Description

{Method for operating trade of building to one-way in multiple real and virtual situation}

The content disclosed in this specification relates to the field of real estate building transactions. More specifically, when trading buildings, etc., the actual situation of the building object is confirmed through encryption of transaction information, and transaction and management are carried out through security verification. It is done.

Generally, real estate includes buildings, and brokerage services for sale, exchange, and lease are performed by real estate agents.

However, in this brokerage business, the seller entrusts the item for sale to a specific certified real estate agent office, and the buyer visits the place to confirm conditions such as the location and price of the building, and then makes the transaction through a contract.

Like this, in the past, you had to go out of your way to make a transaction, and it was difficult to obtain better information because contracts were made through a certified real estate agent office.

Therefore, portal sites such as Naver and Daum are providing better convenience to people who are looking for housing by using the map services provided. For example, these services provide textual explanatory information that explains the location of the building, the type or characteristics of the property, and images to confirm the location. However, most people spend a lot of effort searching for and comparing houses in person to choose the right one.

Accordingly, there has recently been the launch of a service that provides rental information and vacancy information, and through these services, various information can be obtained easily and quickly. Since a lot of information is publicly available, a brokerage service allows users to quickly and easily request properties for sale, lease, and lease. There are also services (exchanges), etc.

However, from the customer's perspective, they are flooded with a lot of listing information, and although they can find the information they want quickly and easily, it sometimes takes extra effort to find out what kind of house or building is actually for sale. Therefore, it is difficult to quickly find a building that customers actually like.

On the other hand, these buildings, etc. require relatively high costs, and the value may vary depending on the situation and location for each transaction. It is common to purchase by referring to similar transaction prices, and the more transaction information that can be used as a reference, the more transparently the transaction is performed. do.

For example, in a situation where so much information is viewed, searched, and used, it is necessary to protect it as personal information.

Therefore, when trading a building, etc., in order to know what kind of building is actually for sale, it is necessary to check the actual situation of the building based on information about it and ensure the safety of information about the transaction and ownership.

Additionally, the prior art literature on the background for this safety is the literature below.

(Patent Document 0001) KR102207993 Y1

(Patent Document 0002) KR102008757 Y1

For reference, similar to this specification, Document 1 allocates an encryption key separately to the platform operator when managing information security, thereby providing security when transacting with such information.

And, this document 2 also concerns blockchain-based data security methods. This method includes the steps of generating information, encrypting it, and storing it in local storage, determining the data to be distributed and processed for the stored information according to setting conditions, and dividing the determined information into several pieces according to setting conditions. Security processing, including steps.

On the other hand, since transactions involving such buildings are relatively expensive, it may be possible to provide this information at a desired location or in a convenient situation through a brokerage exchange, etc., while allowing for a little more personal information protection. For example, it may be possible to use virtual reality.

To explain a little further, objects such as buildings in this way have asset value and can be traded with others, and during the transaction process, it can be conveyed after confirming that it is a clear transaction object (or ownership). To elaborate, this virtual reality refers to creating a specific situation like this and making it as if you are interacting with the real surrounding situation.

However, in the case of high-rise buildings on real and virtual maps, location-based data is provided in various currently released real-world map application service platforms and virtual world platform services, as well as location information for each floor and the building's internal structure and accurate They tend not to provide location.

The disclosed content is that when trading building objects in real and virtual situations, the actual situation of the building object is confirmed to the legitimate user from a specific encryption of the building object, and various realities of transaction and management are conducted through security verification. We aim to provide a single building transaction operation method in the virtual world.

In addition, when conducting such transactions, attribute information including the location information and structure of the relevant building is additionally provided to accurately distinguish the location of the space and utilize the location, altitude, and floor information even in the virtual world.

So, according to this, the multiverse service has been further expanded from the metaverse service, that is, not only the current location information, altitude information, and floor information, but also the time points of the present, past, and future, and whether it is a three-dimensional world, a four-dimensional space including time, or multiple high-dimensional spaces. Using data that specifies, data that transcends time and space is recorded as block information. In addition, this block data will be registered, managed and operated using blockchain-based technology to provide services that can be used to utilize various metaverse multiverse platforms that transcend time and space.

The method of operating a single building transaction in various realities and virtual worlds according to embodiments is,

When trading buildings in various situations such as reality, the location, altitude, number of floors, time, and dimension information of the building in the real world and the virtual world are encrypted and managed in blocks, and blockchain technology is used to provide platform services. to provide.

In addition, by additionally providing property information including location information and structure of the building in question when conducting such transactions, the location of space is accurately distinguished and location, altitude, and floor information is utilized even in the virtual world.

Therefore, location-based data from various real world and virtual world platform services is characterized by providing accurate information such as the location and internal structure of the building when there is a building on a real or virtual map.

Specifically, as before, when an object to be purchased or sold is traded between multiple different users, the transaction information of the corresponding object is stored in the control unit of the relevant service information processing device (or the corresponding platform information processing device). Whenever a transaction is made on the blockchain, a transaction is formed and encrypted into a block.

Therefore, by uploading and managing this information to the registration blockchain network, transaction information can be securely managed for each different user.

And, in this state, depending on the embodiment, if the transaction information is a building object in a real situation or a virtual situation, the first format below is preset and registered in the blockchain, and each time a transaction is made through this, the actual object of the building is registered. Please confirm the situation with the legitimate user. Then, after security verification, the transaction is made, and after completion, it is uploaded and managed. In addition, in the case of a transaction, additional attribute information including location information and structure of the building to be traded is provided.

In addition, the first format processes transactions in the order in which attribute information, including the location, altitude, number of floors, time, and dimensions of each building for each building object for a plurality of different users, is given to each attribute according to the importance of each different attribute. Each time it is configured, it is characterized by blocks for each real/virtual situation and distributed encryption.

According to embodiments, when trading buildings, etc. in real and virtual situations, information about the location and altitude of the building is sequentially block-blocked and distributed encryption is performed to confirm the actual situation of the building object to the legitimate user. Therefore, transactions and management are carried out through security verification.

In other words, data such as location, altitude, number of floors, time, and dimension are blocked for various metaverse platform services in the real world or the virtual world, and security verification management is made easy with blockchain technology, so that the real world, virtual reality, metaverse, etc. Provides services that utilize and operate multiverse platform services.

In addition, by additionally providing attribute information including the location information and structure of the building in question in the case of a transaction, the location of the space is accurately distinguished and the location, altitude, and floor information is utilized even in the virtual world.

Therefore, location-based data from various real world and virtual world platform services provides accurate information such as the location and internal structure of the building when there is a building on a real or virtual map.

Therefore, through this, the multiverse service is further expanded from the metaverse service, that is, not only the current location information, altitude information, and floor information, but also the present, past, and future time points, and whether it is a three-dimensional world, a four-dimensional space including time, or multiple high-dimensional spaces. Using data that specifies, data that transcends time and space is recorded as block information. In addition, this block data is registered, managed and operated using blockchain-based technology to provide services that can be used to utilize various metaverse multiverse platforms that transcend time and space.

Also, in this case, when requesting a transaction and managing registration at a brokerage exchange, various management is performed in conjunction with this, providing stabilization of information management and better security verification and management.

1 is a diagram conceptually illustrating a method of operating a single building transaction in various real and virtual worlds according to an embodiment.

As shown in FIG. 1, the method of operating a single building transaction in various realities and virtual worlds according to an embodiment includes, as before, at least one user terminal 100, a brokerage service information processing device 300, and at least one An information processing device 400 is used to provide information.

Here, the user terminal 100 is a terminal of a buyer or lessee who wishes to manage the transaction information of the building before or after the contract according to security verification using web pages, programs, or applications related to building transaction services. You can. In addition, at least one user terminal 100 inputs transaction information and user information and receives building transaction information.

When the brokerage service information processing device 300 receives a transaction request from the user terminal 100, the brokerage service information processing device 300 collects information from at least one information providing information processing device 400, analyzes the transaction information, etc. according to a preset algorithm, and then analyzes the transaction information, etc. The results are transmitted to the user terminal 100.

When conducting such a transaction, the information providing information processing device 400 provides various situational information regarding the building transaction to the brokerage service information processing device 300 to facilitate the transaction.

So, in this state, according to one embodiment, the single building transaction operation method in these various realities and virtual worlds performs the following operations in the brokerage service information processing device 300 (or various service information processing devices).

In other words, when trading buildings in real and virtual situations, the information about the location and altitude of the building is sequentially block-coded and distributed encryption is performed to confirm the actual situation of the building to the legitimate user, thereby ensuring security verification. Transactions and management are carried out through

In other words, when trading rental buildings, etc. between users in multiple locations, the location, altitude, number of floors, time, and dimension information of the building in the real world and the virtual world are encrypted and managed in blocks for each user and building, and are managed using blockchain. We utilize technology to provide platform services.

So, in addition to the multiverse service, which is a further extension of the metaverse service, it provides not only current location information, elevation information, and floor information, but also current, past, and future time points, and whether it is a three-dimensional world, a four-dimensional space including time, or multiple high-dimensional spaces. Using the specified data, data that transcends time and space is recorded as block information. In addition, this block data is registered, managed and operated using blockchain-based technology to provide services that can be used to utilize various metaverse multiverse platforms that transcend time and space.

In addition, when conducting such transactions, attribute information including location information and structure of the relevant building is additionally provided to accurately distinguish spatial location and utilize location, altitude, and floor information even in the virtual world.

Therefore, location-based data from various real world and virtual world platform services provides accurate information such as the location and internal structure of the building when there is a building on a real or virtual map.

So, overall, through this, one embodiment confirms to the legitimate user the actual situation of the building object, that is, that the building being traded while maintaining security is the actual object of transaction, and allows the transaction to be made accurately with the location and structure of the building. Provided in this situation, security verification makes transactions and management safe and transparent.

Specifically, the method of operating such a transaction is as follows.

In other words, when an object to be purchased or sold is traded between multiple different users, the control unit of the service information processing device (or the platform information processing device) trades the transaction information of the corresponding object on the blockchain. In each case, a transaction is formed and encrypted into a block.

Therefore, by uploading and managing this information to the registration blockchain network, transaction information can be securely managed for each different user.

And, in this state, according to one embodiment, when the transaction information is a building object in a real situation and a virtual situation, the first format below is preset and registered in the blockchain, and each time a transaction is made through this, the building object is registered. The actual situation should be confirmed to the legitimate user. Then, after security verification, it is uploaded and managed. In addition, in the case of a transaction, property information including location information and structure of the relevant building is provided.

In addition, the first format stores attribute information, including the location, altitude, number of floors, time, and dimensions of each building for each building object for a plurality of different users, in the order given to each attribute according to the importance of each different attribute, transaction. Each time it is configured, it is divided into blocks for each real/virtual situation and distributedly encrypted.

Additionally, in this case, this trading operation method first involves service providers, for example, various traders directly or indirectly producing virtual content (building objects, etc.) and providing it in various ways through brokerage exchanges, etc.

So, these building objects, etc., have asset value and can be traded with others, and in the process of trading the object, it can be delivered after confirming that it is a clear transaction object (or ownership). A method is required. To this end, blockchain-based blocking is used to ensure that only legitimate users can verify or transact the actual situation of the object.

To this end, by verifying security using the above-mentioned configuration for various real and virtual situations, the rights of the building object in real and virtual situations are protected and various conveniences and benefits are provided.

In addition, whenever there are multiple buildings on a real or virtual map, location-based data is provided in various reality and virtual world platform services, and detailed location information and internal structure of each building are provided accurately.

Additionally, when trading in a metaverse virtual situation, etc., security verification is performed by checking and managing the actual situation of the building in advance. In this case, this security verification method is also used on the blockchain transaction server. to provide appropriate services.

Therefore, the actual situation of the building is managed accordingly to enable transparent and safe transactions, and furthermore, various management is performed in conjunction with this when requesting sales to other brokerage exchanges and managing registration. Accordingly, it also provides stabilization of information management and better security verification and management.

On the other hand, in this transaction operation method, when transaction information for a building is registered according to these embodiments, from the next transaction, a specific number of transactions with similar transaction information among the transactions for buildings of the same type in the surrounding area within the setting area are registered. Extract as much actual transaction information as possible.

Therefore, by providing price change information from the actual transaction price information extracted in this way, actual transaction information according to the actual situation is also provided.

And, when a transaction is completed based on this price change information, the corresponding information is similarly block-blocked from the above-mentioned blockchain and uploaded to the registration blockchain network for management.

For reference, as shown in the prior art, when a landlord or the like logs in, a list of buildings managed (or owned) is printed and serviced.

For example, for each building, the location, building name, year of completion, number of rooms, classification, photo, registration date, and modification date are displayed.

For example, to explain in detail, the method of providing such price change information is as follows (belongs to the prior art).

First, a lot of public information is collected, and then actual transaction price information and characteristic information of the building are collected.

Afterwards, information about the building is derived from a number of public information.

For example, from the actual transaction price information and characteristic information, information on the location, use area, and area are all considered to be the same building, and street number information is obtained. Then, from this information, the transaction amount can be divided by the area to calculate the price per area, and the location of the building in question can be obtained using a geographic information system (GIS).

Afterwards, the information on the property is confirmed according to a request for property registration from a lessor, etc. or a request for information about the property from various users.

Then, the characteristics of the property are extracted.

Afterwards, the distance to adjacent buildings with similar characteristics in the area containing the property is calculated.

Next, the number of building objects to be considered in calculating price change information is determined according to the distance to these adjacent building objects.

For example, if there are less than the above number of building objects to be considered for price calculation within the area that includes the building object, the scope of the search area is expanded to determine additional building objects to consider the price.

On the other hand, even if the scope of the search area is expanded and additional buildings to be considered for the price are determined, if the number of buildings to be considered for the overall determined price is less than the above number, the decision is made only for the buildings to be considered for the price less than this number.

Afterwards, the average value is calculated from the prices per area of this number of building objects.

For example, the price per area of these building objects can be averaged and multiplied by the area of the building object to calculate the average price.

So, from these average values, the variable price of the building object is obtained.

In addition, in this transaction operation method, when the relevant building object is traded again, other building objects within the same price range are collectively extracted from the transaction information including the price change information blockified in this way and provided in the vicinity within the set area.

And, when the transaction is completed accordingly, it is uploaded and managed in the same manner as above.

Additionally, this transaction operation method is a conventional technology and provides analysis services for rights risk and contract risk. For example, the right risk may be checked based on whether a restricted real right has been established by scraping at least one of the building register, land register, building register copy, and land register copy.

Additionally, in addition to these details, various modifications are possible within the scope of one embodiment.

Figure 2 is a diagram illustrating the entire system applying a single building transaction operation method in various real and virtual worlds according to an embodiment.

As shown in FIG. 2, the system of one embodiment includes a brokerage service information processing device 100 equipped with a blocking method of one embodiment, a lessor terminal 110, a manager terminal 120, and lessee terminals 130 and 140. Includes.

Additionally, the system according to one embodiment performs services through external linkage in conjunction with the brokerage service information processing device 100, and includes a troubleshooting center information processing device (not shown).

Additionally, at this time, each device connects to each other through its own network. In this case, they are connected to each other via TCP/IP, etc., and among user terminals, Wi-Fi or LTE may be used wirelessly with mobile terminals.

The brokerage service information processing device 100 connects the lessor terminal 110, the manager terminal 120, and the lessee terminals 130 and 140 to transmit and receive various information, and transmits and receives various information to/from the lessor terminal 110 or the manager. Information regarding property management is provided to/from the terminal 120. In addition, when trading a building object in a real situation in conjunction with other user terminals 110-140, information about the location and altitude of the building is sequentially blocked and distributed encryption is performed to determine the actual situation of the building object. Since it is confirmed to the legitimate user, transactions and management are carried out through security verification. Additionally, in the case of a transaction, property information including location information and structure of the building in question is provided. In addition, the brokerage service information processing device 100 is also an information processing device of a brokerage exchange, and performs various management using the above method when requesting sales and managing registration at the brokerage exchange, It also provides stabilization of information management and better security verification and management.

The lessor terminal 110 is a brokerage service information processing device (100) provided by a person who is the right holder of the building to be leased or his/her related person (e.g., a family member if the right holder is an individual, a director, etc. in the case of a company) or an interested person. ) to perform the function. In this state, according to one embodiment, the landlord terminal 110 receives the actual situation of the building from a specific service information processing device (including a brokerage exchange) when trading a building object, etc. between users in a real situation, etc. Through security verification, we manage transactions in a safe and transparent manner. In addition, in a transaction situation, property information including location information and structure of the building in question is provided to inform the exact location of the building. In this case, for example, in order to confirm the actual situation of the building, the lessor registers information such as the location and altitude of the building in advance in the brokerage service information processing device 100 and encrypts it into a block. Only ensure security verification and provision of the actual situation of the building. Therefore, after confirming the actual situation of the building through this, the transaction is carried out between the parties, so we create a smooth transaction atmosphere with clear and accurate information about the building being traded while maintaining security and the location of the building. , provides safe and transparent transactions.

The manager terminal 130 provides transaction services for buildings by signing a contract with the right holder (owner, lessor).

The tenant terminals 130 and 140 perform a function that allows a person interested in property information, etc. to access the property and then search for the property, inquire, make transactions, etc.

Figure 3 is an overall diagram illustrating another system applied to a single building transaction operation method in various real and virtual worlds according to an embodiment.

As shown in FIG. 3, a system according to another embodiment includes a number of different user terminals 100 and a web server 200 (i.e., a service information processing device or brokerage service information processing device) equipped with a block method in one embodiment. device), including storage.

The user terminal 100 is a buyer or seller (lessor, lessee, etc.) terminal, and performs a function that allows a person interested in property information, etc. to access the property and search for, inquire about, and conduct transactions for the property. In this state, according to one embodiment, when a building object, etc. is traded between multiple users in a real situation, the user terminal 100 checks the actual situation of the building, etc. from a specific service information processing device (including a brokerage exchange). We manage transactions safely and transparently by receiving and verifying security. In this case, for example, the lessor sends information such as the location, altitude, number of floors, time, and dimensions of the building to the service information processing device 200 in advance in order to confirm the actual situation of the building. By registering and encrypting it through blocking, only the landlord can securely verify and provide the actual situation of the building.

The web server (i.e., service information processing device) 200 is linked with the user terminal 100, and when trading a building object in a real situation, etc., the information about the location and altitude of the building is sequentially divided into blocks and distributed. By performing encryption, the actual situation of the building object is confirmed to the legitimate user, so transactions and management are carried out through security verification. In addition, the web server 200 is also an information processing device of a brokerage exchange in another way, and performs various management using the above method when requesting sales to this brokerage exchange and managing registration, thereby improving information management. It also provides stability and better security verification and management. For reference, a detailed description of this format is provided below. Additionally, when registering transaction information in this way, the web server 200 appropriately classifies a large amount of information from a distributed configuration into the format and location desired by the customer, thereby providing information about the building object, for example, the building object. If the number, type, information capacity, etc. are large, distribute them. For this purpose, if there are multiple building objects or owners, or if the building objects or owners are divided into multiple different locations, groups, and channels, Blocking is also performed on different distributed storages.

Figure 4 is a block diagram showing the configuration of a service information processing device used in a single building transaction operation method in various realities and virtual worlds according to an embodiment.

As shown in FIG. 4, the service information processing device 200 of one embodiment includes an I/F unit 201 for transmitting and receiving various information to the outside, a main processing unit 202 and a database 203 for controlling the same. do.

Additionally, the service information processing device 200 according to one embodiment includes a key signal input unit 204 that receives various setting information according to the user's key operation and a display unit 205 that displays various monitoring information.

The I/F unit 201 is connected to an external customer terminal 100 or storage to receive customer information (customer name, company name, business registration number, etc.), information on the building subject to which the customer will transact, transaction information, etc. Alternatively, registration information based on this information may be distributed and provided.

When receiving building object information and transaction information from the I/F unit 201, the main processing unit 202 sequentially blocks the information about the location and altitude of the building from the above-described first format and performs distributed encryption. By performing this, the actual situation of the building object is confirmed to the legitimate user, allowing transactions and management through security verification, etc.

The database 203 stores and manages building object information and transaction information for each user and building object under the control of the main processing unit 202.

The key signal input unit 204 receives various setting information for transactions of buildings according to the administrator's key operation.

The display unit 205 displays various user interfaces related to building transactions.

Figure 5 is a flow chart sequentially showing a single building transaction operation method in various real and virtual worlds according to an embodiment.

As shown in Figure 5, the transaction operation method of one embodiment is first, when an object to be purchased or sold is traded between multiple different users as before, the control unit of the corresponding service information processing device (or the corresponding platform information processing device) Whenever transaction information of the relevant target is traded on the blockchain, a transaction is formed and encrypted into a block.

Therefore, by uploading and managing it to the registration blockchain network, transaction information is managed securely for different users.

In this state, the transaction operation method according to one embodiment first sets and registers the first format below in the blockchain in case the object is each building object in a real situation and a virtual situation, according to an embodiment. (S501).

And, in this case, the first format is as described above.

In other words, for each building object for multiple different users, property information including the location, altitude, number of floors, time, and dimensions of each building is provided in the order given to each property according to the importance of each property, and each time a transaction is constructed, it is a reality. /Distributed encryption by dividing into blocks for each virtual situation.

Next, the object to be purchased or sold is traded between multiple different users by the blockchain registering the first format (S502-S503). In particular, in these cases, property information including location information and structure of the building to be traded is provided, thereby informing the exact location of the building.

Therefore, whenever the object is traded, after the transaction is completed, the transaction information of the corresponding object is formed into a block from the blockchain in which the first format is registered.

In addition, when the object in question is a building object, the property information of the building is divided into blocks for each different reality and virtual situation according to the user setting information in the first format, distributed and encrypted (S504), and uploaded to the registration blockchain network for management. Do it (S505).

Therefore, through this, the transaction operation method according to one embodiment, when trading buildings, etc. in real and virtual situations, sequentially blocks information about the location and altitude of the building and performs distributed encryption, thereby Since the situation is confirmed to the legitimate user, transactions and management are carried out through security verification.

As described above, in one embodiment, when a rental building, etc. is traded between multiple users in a real situation, etc., the location, altitude, number of floors, time, and dimension information of the building in the real world and the virtual world are divided into blocks for each user and building. It is encrypted, managed and operated, and blockchain technology is used to provide platform services.

In addition, in one embodiment, when conducting such a transaction, attribute information including the location information and structure of the relevant building is additionally provided to accurately distinguish the location of the space and utilize the location, altitude, and floor information even in the virtual world.

Therefore, location-based data from various real world and virtual world platform services provides accurate information such as the location and internal structure of the building when there is a building on a real or virtual map.

Therefore, through this, the multiverse service is further expanded from the metaverse service, that is, not only the current location information, altitude information, and floor information, but also the present, past, and future time points, and whether it is a three-dimensional world, a four-dimensional space including time, or multiple high-dimensional spaces. Using data that specifies, data that transcends time and space is recorded as block information. In addition, this block data is registered, managed and operated using blockchain-based technology to provide services that can be used to utilize various metaverse multiverse platforms that transcend time and space.

On the other hand, in addition, this transaction operation method performs blocking appropriately when there is a lot of characteristic information such as structural information and status information of the building object from the configuration below, so blocking can be performed according to various situations. Let's do it.

For this purpose, the first format is equipped with the first blocking configuration set below.

In addition, the first block configuration is that the building object is provided with a number of different characteristic information, including secondary structure information including size and shape, and status information including noise, vibration, and safety, in addition to the attribute information, or , It is used in various cases where it has management element information including owner information of the building object, or transaction element information including price.

Specifically, blocking is performed from each of these characteristic information, management element information, and transaction element information in the order in which each characteristic, management element, and transaction element is given different importance according to the importance of each characteristic, management element, and transaction element. It is provided.

Also, as another example, this configuration may be as follows.

Looking at this background first, when registering transaction information in this way, a large amount of information from a distributed structure is appropriately classified into the format and location desired by the customer, such as information on building objects, such as the number and type of building objects, In cases where there is a large amount of information, etc., it may be distributed.

In other words, if there are multiple building objects or owners, or if the building objects or owners are divided into multiple different locations, groups, and channels and transact, multiple different transactions are made corresponding to the number, location, group, and channel of the building objects or owners. Blocking is also performed on each distributed storage.

In addition, this configuration performs the corresponding blocking according to the encryption configuration set below, so it can be done according to the situation of a building target.

For this purpose, the setup encryption configuration is as follows.

a) First, when information is input from the user terminal (or in file->plaintext format), a different secret key is selected depending on the shape or length of the plaintext.

Also, according to the size of the secret key, one of a number of different rounds is selected and executed repeatedly to obtain the ciphertext.

In addition, the function for each round applies the ARIA encryption format including round key addition, substitution layer, and spreading layer.

b) So, before performing the round key addition operation, first perform exclusive OR with n-1 scramblers (n is the number of building objects or owners, or the number of locations, groups, channels) from the plaintext and secret key. Modify it by doing.

c) Then, the modulation information is set to n partial secret keys.

d) So, when the modulation is performed in this way, the ciphertext is obtained by repeatedly executing it as a function for each round including one round of round key addition operations according to the secret key size.

Accordingly, each time the ciphertext (format) is obtained, the scrambler systematically destroys the round key addition operation and the operation result is obtained in the same format as the commercial AES.

On the other hand, a single building transaction operation method in these various realities and virtual worlds must ensure the safety of data on transaction records and ownership, and for this purpose, transactions may be possible using NFT (NonFungible Token). do.

For this purpose, the second format below is preset and registered in the blockchain.

In addition, in the second format, when managing a building object, each building owner records video or audio data related to the building owner's ownership in the building object information and the building object transaction information for each building object and/or transaction type. It is converted differently into an NFT by an NFT-free process, creating ownership-related NFT information.

In addition, the ownership-related NFT information is uploaded and registered on the registration blockchain network, and ownership authentication is performed for each transaction of the corresponding building object according to the registered ownership-related NFT information.

Therefore, whenever a building object is traded, the NFT information received through the user terminal from the blockchain that registered the second format (including NFT information related to ownership of the building object/transaction information) is converted into an NFT regarding the owner of the building object. Compare with information (including NFT information related to registered ownership).

As a result of the above comparison, if the NFT information received through the user terminal and the NFT information about the owner of the building object are both identical, it is certified as a legitimate object.

On the other hand, if the NFT information received through the user terminal and the NFT information about the owner of the building object are different, it is certified as not a legitimate object.

On the other hand, if it is certified as a legitimate object, the information and transaction information of the building object corresponding to the registration blockchain network are uploaded, so the transaction information is securely verified and managed.

On the other hand, in addition, this method of operating a single building transaction in various realities and virtual worlds enables distributed storage of information from the following configuration when encrypted in this way, enabling effective distributed storage on the other hand.

To briefly explain this background, as terminals become more high-performance and high-capacity, the importance of protecting and managing important information inside the terminal is emerging.

In order to protect and manage such important information, a method of backing up the important information of the terminal by encrypting it and storing it in an external storage device has been used in the past.

However, if important information is stored in an external storage device, a problem may arise where important information is easily leaked if the storage device is hacked.

Therefore, when storing important information in an external storage device, a more secure method is required.

For example, this configuration first constructs a secret key equal to n-1 scrambles, that is, the number of storages as described above minus one, and creates n pieces of distributed information using this secret key.

To explain more specifically, a t-1st order random polynomial (f(x)) with a constant term as secret information is selected, and values from 1 to n are assigned to x of the t-1st order random polynomial (f(x)). By substituting, n pieces of distributed information can be generated. At this time, t represents the number of distributed information required to recover secret information.

Then, configure a specific secret key.

Next, n-1 random keys, that is, n-1 scrambles, are generated, and both the secret key and the n-1 random keys are bitwise XORed.

Then, this information can be set into n partial secret keys, and a different partial secret key can be transmitted to each of the n storages.

Then, each of the n pieces of distributed information is encrypted with a secret key to generate n pieces of encrypted distributed information.

Then, n pieces of encrypted distributed information are transmitted and stored in corresponding n storage units. For reference, this method is also used in the same way as the above method.

Therefore, before transmitting this encrypted distributed information, a process can be performed to verify whether n storage units are legitimate users.

Meanwhile, this method explains the process of recovering the information distributed and stored here when encrypted in this way.

First, when receiving a request for recovery of secret information, encrypted distributed information is received from at least t of the n storages. In this case, before receiving encrypted distributed information, an authentication process with t storage units can be performed.

Then, configure the secret key

For example, if a secret key is stored internally, this secret key is used, and if not, a secret key is created separately. And in this case, if the secret key cannot be configured internally, the secret key can be obtained through n storages.

Obtaining a secret key through n storages involves authenticating with each of the n storages, receiving n partial secret keys from the n storages, and performing a bitwise exclusive OR (Bitwise XOR) on all the n partial secret keys received. ) to create a secret key. This method may additionally be used together with the two methods described above.

Then, t pieces of encrypted distributed information are decrypted with a secret key to create t pieces of distributed information.

And also, the secret information is recovered using t pieces of distributed information.

To explain the process of recovering secret information in more detail, the t-1st order random polynomial (f(x)) is recovered using t distributed information, and the constant term of the t-1st order random polynomial (f(x)) You can check and recover the constant term as secret information.

Additionally, during the process of distributing and storing secret information in this method, the process of creating distributed information is explained a little further as follows.

First, n pieces of distributed information (S1, S2, ...Sn) are created using the secret information to be distributed and stored.

Then, in order to generate n pieces of distributed information, a t-1st order random polynomial (f(x)) with a constant term as secret information is selected, and 1 to n are added to x of the t-1st order random polynomial (f(x)). By substituting values up to n, n pieces of distributed information (S1, S2, …Sn) can be generated. At this time, t represents the number of distributed information required to recover secret information.

And, distributed information is also stored in the blockchain. In this case, the distributed information may include user identification information, the master storage selected by the user, a list of n storages selected by the user, and the number (t) of distributed information required for recovery.

Additionally, you can request a secret key for the distributed storage service by performing the master storage authentication process.

Then, if authentication is successful, the master storage verifies the record of distributed information stored in the blockchain.

Meanwhile, in addition to this, in the process of distributing and storing secret information in this method, the process of generating encrypted distributed information is explained as follows.

First, the master storage then generates a secret key (V) and generates n partial secret keys (V1, V2, ...Vn) using the secret key (V).

Master storage generates n-1 random keys, sets the n-1 random keys to n-1 partial secret keys (V1, V2, …Vn-1), and combines the secret key and n-1 random keys. A partial secret key (Vn) is generated by performing bitwise exclusive OR (Bitwise XOR). So, finally, n partial secret keys (V1, V2, …Vn) are generated.

Then, the master storage transmits the generated secret key and records the transmission of the secret key to the blockchain.

Additionally, when receiving a secret key from the master storage, each of the n pieces of distributed information (Si) is encrypted with the secret key to create n pieces of encrypted distributed information (Ti).

On the other hand, during the process of distributing and storing secret information in this method, the process of transmitting encrypted distributed information to storage devices and completing distributed storage is explained.

First, an authentication procedure is performed with a storage device that does not transmit encrypted distributed information among n storage devices.

Then, the encrypted distributed information corresponding to the authenticated storage is transmitted to the authenticated storage device. That is, the ith encryption distributed information (Ti) is transmitted to the ith storage device.

When the i-th storage device receives the i-th encryption distributed information (Ti), it records in the blockchain that it has received the i-th encryption distributed information (Ti) and requests the i-th partial secret key (Vi) from the master storage. .

When the master storage receives a request for the i-th partial secret key (Vi), it transmits the i-th partial secret key (Vi) among the n generated partial secret keys to the i-th storage device.

When the i-th storage device receives the i-th partial secret key (Vi), it records in the blockchain that it has received the i-th partial secret key (Vi).

These operations are performed for each n storage units. That is, it is repeated n times.

The master storage verifies that n storage units have received the partial secret key through the blockchain and records it on the blockchain, confirming whether the storage of the encrypted distributed information has been completed. And, when completed, it reports that distributed storage of secret data has been completed.

On the other hand, in addition, this transaction operation method and its corresponding distribution method maintain databases consistent with each other when transmitting and receiving various types of information, thereby providing services quickly and conveniently.

For this purpose, the service information processing device performs the following operations.

a) First, tables storing device registration information and data of customer terminals (i.e., user terminals) or user mobile terminals, storage, etc. are provided identically to each other, and matching relationships for the tables are set and registered in advance.

b) So, when changing information in a table, the tables are synchronized according to the matching relationship.

c) And, when synchronizing the tables, the databases are consistent by diversifying information for each data type for multiple different device (or service) types.

Additionally, when providing various types of information, this method allows the service to be provided effectively by providing customized information according to the wishes of various users from the configuration below.

To this end, this configuration first provides a smooth service by finding and providing information suitable for each user from the format below when exchanging information between users.

For example, this format is:

a) First, classify information about building objects, users, transactions, etc. by multiple different building objects and transaction types.

In addition, a format for modeling by classifying, combining, and learning the above information representing the user's activities for each type is defined.

b) In addition, datasets for each type of information and datasets for the above information representing user activities for each type are extracted separately in different places and time periods.

c) Attribute the dataset to reflect the different transaction locations and times providing the service, and types of surrounding conditions.

d) Next, using the above-attributed information, determine the properties of information about building objects, transactions, etc., and information indicating user activities for each type.

e) And normalize the decision information.

f) So, using the decision information, information on building objects, transactions, etc., and corresponding information representing user activities are modeled for each type.

Through this, independent (recommended information on building objects and transactions) and dependent (information on building objects, users, transactions, etc. by transaction type, etc., and corresponding information indicating the user's activities) are used to recommend building objects and transaction information tailored to each user. ) Set the variable.

g) Then, learning and training data are generated using the above setting information.

h) So, through this, the above-described format is configured using the generation information.

Meanwhile, in this case, additionally, when providing content such as music and background video, this service method allows people to easily and comfortably learn about the relevant information, thereby helping them to know the information.

a) For this purpose, this service method first provides analog sampling information in advance by matching a number of different analog intervals, periods, and cycle information set for different video types in the service information processing device, etc., when providing video content such as background video. Register. In this case, the video type is set separately for each service information processing device and mobile terminal.

b) In this state, when delivering video content, each piece of information is sampled differently from the analog sampling information and animated.

c) Therefore, the digital video sampled in this way is converted into a different GUI for each setting video (or video type), and the video information is returned with an animation suitable for each device.

Additionally, when providing information in this way, this method provides information tailored to various device resolutions, allowing it to be provided in a variety of situations.

For example, in this case, the resolution is set separately for each service information processing device and mobile terminal.

To this end, a type of analog sampling information with an irregular sampling interval but a certain pattern is registered by matching the analog interval, period, and cycle information differently for each resolution type for each image (or image type).

Therefore, by converting digital color images processed with this information into different UIs with GUIs matching each type, the corresponding image information is animated and returned.

At this time, in order to enable additional image processing for each mobile device, it has the following configuration.

In other words, when creating a different UI for each type of image, the corresponding GUI is subdivided and set for each type of mobile device to provide image processing tailored to each mobile device.

On the other hand, in addition to the above, this method allows information to be provided quickly and conveniently by extracting information according to each image information.

For example, when providing the corresponding information, the video content composition information is normalized from a normalization format with edge matching information matched to multiple different video content types, and information is extracted for each composition.

Next, in this state, the normalization format further subdivides the edge matching information for a number of different video content types.

In this case, the GUI for each video, such as mobile, is subdivided and set according to the type of video content, and the videos, such as mobile, are animated multiple times.

Additionally, this method, when providing a variety of information, allows the work owner to re-publish the work in a pretty and nice form, using the structure below, so that it can also be provided to multiple users.

For this purpose, for example, first, the writer terminal, that is, the work owner terminal, can receive a work creation user interface from the server when another user completes the payment for the work, and use it to create the work. In this case, by providing this information differently for each work and transaction type in the format described above, a better service can be provided. That is, and in this case, this work creation information is organized by categorizing different works and transaction types.

Next, when executing the work creation user interface in this way, the work creation user interface can operate the front camera of the work owner's terminal to capture an image in front and save the captured image in the corresponding terminal, that is, the artist's terminal.

And when creating a work through the work creation user interface, the work creation data can be saved in the writer's terminal by capturing the screen every time the writer inputs something on the screen or at a certain set time.

At this time, the artist's terminal can match and store the artist's filmed video and work creation data generated through the user work creation interface.

Work creation data means that when a writer runs a work creation user interface that includes work tools provided from the server to create a work, the screen is captured every time the writer makes an input on the screen of the writer's terminal or at a set specific time period. What is saved is called work creation data.

Additionally, the work creation data may consist of a plurality of screen capture images.

As each captured video data that constitutes the work creation data is automatically played in chronological order, a video can be created that shows the creation process from the beginning to the end of the work creation in animation form.

The video is configured so that the work creation data and the artist's footage can be displayed on a single screen, and the artist's footage can also be configured to automatically play in chronological order.

In a further embodiment, the user work creation interface determines whether the shape of a human face is detected in the artist-shot video, and if not detected, provides a notification to project the face into the camera's shooting area, or disables the work creation user interface. Can stop work creation

In an additional embodiment, it is possible to check whether the person in the image being filmed on the artist's video is the same as the artist performing the work transaction event. The server compares the characteristic points of the person in the image captured in the artist's video with the image of the artist performing the work transaction event, and displays on the orderer's terminal whether the artist performing the actual work transaction event and the person in the artist's video are the same person. can do.

The server can receive the artist's shooting video and work creation data from the artist's terminal, process the video so that it is displayed in a multi-layer format, and provide it to other user terminals.

After completing the work, the artist's terminal can transmit the artist's video and work creation data to the server along with the completed work.

The server can process and transmit the work creation data and artist-filmed video sent to the orderer's terminal so that they are displayed as a single video in a multi-layer format.

At this time, the artist-shot video is displayed in one area of the work creation data screen and can be provided in a smaller area than the work creation data screen.

For example, in this case, the process from registration of the work to completion of the transaction is as follows.

First, the method of registering a work transaction event is to connect to the server using an artist terminal or another user terminal with a specific program or application installed, and register the work transaction event.

At this time, a work transaction event means that an artist or orderer registers a work transaction through each terminal. The contents of the work transaction event include the person who registered the work transaction designating the work availability period and registering it on the server, including information such as the type of work, conditions for not accepting orders, work price, delivery date, deposit information, refund criteria, and sample works. You can.

Artists and clients can view work transaction events registered on the server through the artist's terminal or other user terminals, and can bring up a conversation message window to communicate with the terminal where the desired work transaction event has been registered.

After coordinating the details between the matched artist and the orderer through the work transaction event, a transaction confirmation signal is sent to the server from each terminal.

As described above, the artist terminal or other user terminals can open a conversation message window to communicate with the terminal that has registered the desired work transaction event, and at this time, the writer terminal and other user terminals can coordinate details about the work.

At this time, details about the work may include information such as the type of work, conditions for not accepting orders, work price, delivery date, deposit information, and refund criteria.

When details have been coordinated between the artist's terminal and other user terminals, detailed information can be entered into the server and a transaction confirmation signal can be transmitted through the terminal registered for the work transaction service.

At this time, the server provides an interface where detailed information is input to the writer terminal or another user terminal, and the writer terminal or other user terminal can check the details and transmit a transaction confirmation signal.

After receiving transaction confirmation signals from the artist's terminal and other user terminals, the server requests payment for the work, and the orderer pays for the work.

When the server receives transaction confirmation signals from the artist's terminal and other user terminals, it can provide an interface including information such as the price of the work and deposit method according to the details entered here.

You can deposit the cost of the work using another user terminal using the interface provided by the server.

At this time, the interface provided by the server to other user terminals includes a payment module and can provide payment methods including real-time bank transfer, card payment, etc.

When another user's terminal deposits the payment for the work, the server can confirm the payment for the work and send a payment confirmation notification to the artist's terminal.

When payment for the work is completed from another user terminal, the artist terminal receives the work creation user interface from the server, creates the work, and stores the work creation data and the artist's filmed video 420 in the writer terminal.

The artist terminal can receive a payment confirmation alarm from the server and a user work creation interface that includes production tools.

The writer terminal can create a work using the provided user work creation interface.

When the work is completed, the artist terminal can transmit the work creation data and artist-filmed video to the server along with the completed work and transmit a work completion signal.

When the work is completed, the artist terminal can transmit the work creation data and the artist-filmed video to the server along with the completed work, and can transmit a work completion signal when the transmission is complete.

Other user terminals receive work creation data showing the completed work and artist-shot video from the server, and can transmit a work receipt signal if there are no problems.

Other user terminals can check the work creation data provided by the server in which the completed work and the artist's filmed video are displayed in multiple layers.

If there are no problems with the completed work or work creation data, a work receipt signal can be transmitted to the server.

When the server receives both the work completion signal and the work receipt signal, it transmits the amount paid by the orderer to the artist terminal.

When the server receives both a work production completion signal from the writer terminal and a work receipt signal from another user terminal, the server can transfer the work fee paid by the other user terminal in the previous step to the writer terminal.
