Description

System and method for domain search / registration on client PCs {SYSTEM AND METHOD FOR DOMAIN SEARCHING / REGISTRATION OVER THE CLIENT PC}

The present invention relates to a domain search / registration system and method on a client PC. Specifically, a client downloads a domain search engine from a server to a client PC, creates and manages its own domain DB, and stores the domain stored in the domain DB. The present invention relates to a domain search / registration system and method on a client PC that enables a domain search and registration in real time.

More specifically, in the case of a new top-level domain that has not yet been confirmed, the extension and the mutual significance of domains are reviewed in advance and made into a DB, and displayed according to their importance, and stored directly on the client's PC for editing (creation, modification, and deletion). The present invention relates to a domain search / registration system and method on a client PC which enables the user to remove the trouble of having to input important keywords again and search by enabling this at any time.

Recently, with the development of information and communication technology and the explosive growth of Internet users, Electronic Commerce (EC) through the Internet has emerged as a new economic activity.

The Internet is no longer just a channel of information and communication, but it has become a global market, a new market that overcomes the temporal and spatial limitations of traditional markets and brings the world together without the concept of borders.

The United States and the world's leading companies, including the United States, are aware of the growth potential and development potential of the Internet e-commerce market and are making great efforts to take the lead in the Internet market.

Governments, institutions, companies and shops around the world have established homepages and virtual shoppingmalls on the Internet to carry out marketing and sales activities to consumers. As part of this marketing, it's important to provide quality information so that more consumers can visit homepages and virtual stores opened over the Internet, but it's important to have a domain name that you can easily associate with after listening or visiting. There is an increasing need to own a web address (hereinafter referred to as a URL) of a Domain Name.

As such, governments, institutions, corporations, and shops on the Internet who want to use e-commerce can recognize the importance of the added value created by online domain names that play the same role as a store's trader. It's been a long time since the competition for name preemption, and it's limited to seven top-level domains, namely '.COM', '.ORG' and '.NET'. Not only has it been corrected, but now people have preoccupied domains and sold them at a high price, which is becoming a social problem worldwide.

As the importance of domain names grows, a number of websites that provide services such as domain search, registration, and transaction on the Internet have been created, and services are currently performed through the Internet.

However, the conventional domain management system searches manually by inputting arbitrary words one by one manually or checks various types of top-level domains (hereinafter, referred to as domain extensions) by check boxes and checks whether domain names are registered. It is a form of searching whether the domain is registered, and sometimes even when the unregistered domain is discovered, the domain can be registered only after typing and entering personal information and card information each time.

In addition, there is no special organization or Internet service provider for managing the entire domain list owned by an individual or company. Or the problem of handing over to a competitor appeared.

Therefore, there is a need for a new type of domain management system in which these problems are eliminated.

Therefore, the present invention was devised to solve the above-mentioned problems, and in the case of a new top-level domain that has not yet been determined, the extension name and the mutual significance of the domain are reviewed in advance and made into a DB and displayed according to the importance of each client. It is an object of the present invention to provide a domain search / registration system and method on a client PC that eliminates the need to re-enter important keywords again and again by storing them directly at any time.

Another object of the present invention, as well as arbitrary word search, can be used to search the already recognized domains that have been verified in the market with basic data, and above all, the difficulty of domain search and registration due to the explosive increase in domain demand and extension name, etc. It is an object of the present invention to provide a domain search / registration system and method on a client PC.

Yet another object of the present invention is to share information related to cross-domain sales between clients, so that when a desired domain is searched, the sales information of the corresponding domain can be viewed, and when the deposit is made through the card payment system, the operator changes the domain. It is an object of the present invention to provide a domain search / registration system and method on a client PC that performs the escrow function by executing the transaction and remitting the deposit amount to the seller.

Another object of the present invention is to find a non-registered domain among the important domains and individual clients judged to be valuable in a short time, and introduce a shopping mall concept in the domain registration procedure. An object of the present invention is to provide a domain search / registration system and method on a client PC that can realize a user-oriented interface so that registration is possible.

Another object of the present invention is to make it possible to search more than 100 domains and more than 10 extension names (top domains) at the same time, and the search results are colored whether registered or unregistered in order to know whether the domain is registered at a glance. It is an object of the present invention to provide a domain search / registration system and method on a client PC.

A domain search / registration method on a client PC of the present invention for achieving the above object comprises the steps of: a client accessing a web server via the Internet to download a domain search engine program; Database, by the client's discretion, dividing the domain list into categories on the client-side computer; When the client selects a category of a domain to be searched for and then requests a search, searching whether the domain list of the domain list corresponding to the category is registered and displaying whether or not the domain is registered / unregistered for each category through a browser of the client; Searching a list of domains displayed for each category by a client, and then selecting a domain to be registered among unregistered domains; And when the client requests registration of the domain selected from the domain list for each category, the web server displays and pays the status and cost of the requested domain.

In addition, the domain search / registration method on the client PC of the present invention, in the step of the client selects a domain to register among the unregistered domain, if the client wants to buy and sell the registration domain owned by the web server By establishing communication between clients through the client, the client inputs the intention of domain ownership such as domain sale request, lease request, and hypocrisy into the web server, and the other client sees the latest information updated from the web server on his PC. Retrieving posts related to domain sales of a; If the client makes a domain sale related intention about a domain sale related post retrieved from another client, and the client's intention is entered into the web server again, the web server reflects the change on the next page. Characterized in that it further comprises the step of being able to check.

In addition, the step of displaying whether or not the domain is registered or unregistered is characterized in that the domain name that is already registered is displayed in a visual manner so as to search for the domain which becomes available for registration after the expiration date among the preemptive domains.

In addition, the domain search / registration system on the client PC of the present invention can download a domain search engine program through the Internet to enable domain search, registration, sale, exchange, and lease, and has a general purpose or dedicated browser for displaying the same. With one client; Database server that holds domain search program to search each domain among the domain list that database is divided into categories and databased in client side computer by client arbitrarily, and holds all data information and client information necessary to execute the program. ; And an operation server connected to the Internet through the client to manage and control the database server, and to enable data transmission to the client browser and data reception from the client on the Internet.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram illustrating the concept of a domain search / registration system on a client PC according to the present invention.

First, the client 10 who wants to use the Internet web site of the present invention should have a computer, a monitor, a modem, a telephone line, and a corresponding program configured for computer communication. need.

In this case, the client 10 refers to a computer used by those who access the site of the present invention through a network such as the Internet in order to use the domain search and registration service according to the present invention.

The client 10 accesses the Internet 20 by wire or wirelessly using a desktop, laptop, notebook, palmtop computer or wireless information communication terminal such as a WAP phone, a wireless Internet phone, a web TV or an IMT2000, and searches and registers a domain. It connects to a site, downloads a domain search engine program to a client PC, searches for a domain in its own computer working environment while connected to the Internet, and simultaneously registers a domain.

The domain search and registration system and method according to the present invention uses a server push, that is, a push technique. This is the first attempt by Point Cast (http: /www.pointcast.com), which allows clients to continuously receive information via the Web, such as a TV, over a channel of their choice. In fact, the push method is a polling method in which a client checks a server and brings data back.

In addition, the push technique ends with a single contact with the web site when accessing an arbitrary web site, but the push technique continuously connects like a TV channel and continuously receives information.

In addition, the domain name list can be arbitrarily stored in the client PC to be deduced and used when necessary. The shared memory can be allocated from the web server 30 to indicate the intention to trade the domain with each other only by checking in their own computer working environment. In this way, it is possible to facilitate the actual sale, exchange, and lease with other clients, so that the client does not have to actively connect to a specific site and offer a domain offer. To avoid the hassle of registering.

In addition, the operating system can be executed in UNIX, Linux, windows, etc., although somewhat different in form, and the protocol can be executed in protocols such as http, ftp, and wap.

2 is an overall system configuration diagram of a domain search / registration system on a client PC according to the present invention.

First, the domain search / registration system on the client PC accesses the web server 30 to download the domain search engine program to receive the service of domain search results and registration procedure through the Internet, and then downloads the downloaded program to the client PC. Installed to enable domain search, registration, sale, exchange, and lease, and a plurality of clients 10 equipped with a general or dedicated browser displaying the same, and the domain is searched according to the request of the client 10, and as a result It consists of a web server 30 that outputs or performs a registration procedure.

The web server 30 has a domain search program that allows the client 10 to arbitrarily determine and search each domain among database lists of domains divided into categories on the client-side computer, and all data necessary for executing the program. A database server 30b holding information and client information, connected to the client 10 and the Internet 20 to manage and control the database server 30b, and to transmit data to the client browser 10a over the Internet; An operational server 30a is provided for enabling data reception from a client.

At this time, the client 10 is provided with the update data module 10b-1 for receiving the update data from the latest information DB of the web server 30 to be displayed through the browser of the client PC 10, the domain name of the It has a domain search and search setting module 10b-2 that enables single search, classification keyword search and combination keyword search to search for registered / unregistered status in real time. In addition, a client is provided with a domain management module (10b-3) for managing the domain DB (10c-3) in which the database of the domain list is divided into categories by the client-side computer by the discretion of the client, the registration held by each client An equal layer function module 10b-4 is provided to enable clients to trade, exchange, and lease by sharing data for the sale, exchange, and lease of domains among clients.

It also has a file management module (10b-5) for cart file management, keyword file management, naming rule file management, whois file management, and an editing function module (10b-6) for selecting, moving, and deleting domain name data. do.

In addition, the client PC of the present invention manages the registration date of the domain DB 10c-1 in which the client arbitrarily determines and divides the domain list into categories on the client-side computer by database, and the registered domain among the domain names in the database. A registration domain management DB 10c-2 is provided.

In the web server 30, the operation server 30a includes a member management module, a control module, an update data transmission module, a domain registration / non-registration search module, a domain registration module, an escrow service module, and the database server 30b is a member. Domain that contains domain information and registered domains divided into categories, consisting of the member information DB that manages member's subscription and withdrawal and member's credit card file, and the domain names that are judged to have economic value verified on the web. DB and web server 30 through the shared memory (not shown) to establish a communication between the client to update the domain ownership related intentions, such as domain sales request, lease request, frostbite, etc. to the operator's server It is equipped with the latest information DB, and the client downloads the domain search engine from the domain search engine program DB. By loading, it is possible to search whether a domain is registered or unregistered on the client PC and perform domain registration through a web server.

At this time, the domain DB of the web server 30 and the domain DB 10c-1 of the client PC 10 have a category assigned to the same category code, a keyword including the corresponding category code, Allows domains containing keywords to be stored in table format.

3A to 3B are flowcharts for explaining a method of operating a domain search / registration system on a client PC according to the present invention.

If the client 10 wants the Internet service of the present invention, the client 10 accesses the client computer to the web server 30 through the Internet 20, registers through the main screen, and then approves through the member DB. After receiving the Internet service of the present invention (S1 ~ S4).

At this time, the member DB stores personal information such as ID, PASSWORD, member's name, social security number, address, telephone number and credit card number.

The web server 30 of the present invention has a function of transmitting data desired by a user to a user browser through an internet protocol.

The client 10, which has been authenticated, accesses the web server 30 through the Internet 20, downloads a domain search engine from the domain search engine program DB, and installs the downloaded domain search engine program on the client PC. (S5).

Of course, the installation of the domain search engine program can be clicked on the domain search engine program installed on the web server 30 to install the program directly on his PC, or by distributing the domain search engine program on CD Various changes to the program installation and distribution methods can be made, such as allowing the program to be installed.

After installing the program, click the domain search engine installed in the client PC to display the main screen as shown in FIG.

As a result, the client arbitrarily judges and divides the domain list into categories on the client side computer to construct a database DB to construct the domain DB 10c-1 in the client side PC 10 (S6).

In addition, the registered domain management DB 10c-2 of the client-side PC stores the owning domain information such as a list of domains registered and owned by the client, a registration date, and a registration expiration date in a table format.

Therefore, when the client wants to check the list of domains owned by the client, a list of all owned domains is displayed, and information such as domain registration date and registration expiration date is displayed together with the domain list to display the re-registration period. This can solve problems such as having to pass on your own domain name to another person or competitor.

At this time, the step of database the domain list by dividing by category, it is possible to mutually join the domain names already generated for each category to enable the registration search according to the combination of important words.

In addition, the creation, modification, deletion, etc. of domain names are performed under the autonomous rights of the client, and the domain names determined to have a verified economic value on the web displayed on the web server 30 are also determined by the client 10. It can be selected for purposes and applied to client-side categories.

For example, the categories of client 10 domains are 'highly-traded domains', 'high-priced domains', 'world famous brands', 'world-wide country names', 'major cities worldwide', 'multinational companies' It can be composed of 'LIST', 'major companies around the world', 'world famous sites', 'North Korea core domains', and 'world famous people'.

At this time, some of the categories of domains are composed of data that has been recognized as commercially verified through the existing web, or the client arbitrarily judges and divides the domain list into categories on the client-side computer by database. .

In the present invention, the domain DB (10c-1) for each category is divided into categories and stored in a table format. The category table is stored by dividing into category codes, category names, upper categories, absolute paths, and the like. . In addition, a keyword including a category code is stored in a table form similarly to a category, and the keyword table is stored separately by a corresponding keyword, category code, addition point, and dictionary solution.

At this time, the domain table is classified into data such as keywords, extensions, automatic evaluation scores, manual evaluation scores, and stored in a domain DB in advance.

In a preferred embodiment of the present invention, the domain search engine program is displayed on the monitor of the client PC as shown in Figs. FIG. 5 is a diagram illustrating a screen displaying domains databased by a client classified by category, and FIG. 6 is a diagram illustrating a screen displayed when a client selects a domain which has been traded at a high price among the categories of FIG. 5. 7 is a diagram illustrating a screen displayed according to a domain registration procedure.

The web server 30 searches in real time whether or not each domain is registered or not registered in the domain list DB, which is databased by category on the client PC, and transmits it to the client-side computer by a push technique (S7 to S8).

That is, when the client 10 selects one of the categories displayed on the monitor, for example, 'highly traded domain', the domain search engine downloaded from the web server 30 searches for the domain DB and the 'high price' A list of data stored with the keyword 'traded domain' is generated, and a list of 'highly traded domains' separated by the domain and the highest extension is displayed on the monitor.

As a result, the domain list data searched for in real time is transmitted from the web server 30 to display whether the domain is registered or unregistered for each category through the browser of the client 10.

At this time, the client 10 can check the displayed image such as the 'high-valued domain list' with the monitor by transmitting the data retrieved by the domain search engine to the web browser of the client 10.

The domain list displayed on the monitor screen of the client 10 is displayed in a certain table format and color so as to distinguish registration at a glance according to the domain corresponding to the category selected by the client and the highest extension name used.

In addition, the domain name already registered is displayed in a visual manner so that the domains that have been registered after the expiration date can be searched among the occupied domains so that the clients can easily find the domains that are valuable but can be registered. Do it.

For example, in the case of the domain name 'Altavista', 'Altavista' is registered in the extensions 'COM' and 'NET', so the entire area in red with 'x' in 'COM' and 'NET' respectively. And nobody has registered for the extension 'ORG', so 'Get It!' Mark the entire area in blue with markers.

In addition, when displaying the domain list, not only the existing top extension name registered according to the domain, but also the new top extension name to be used, for example, 'SHOP', 'WEB', 'INFO', 'ARTS' and 'FIRM' And 'NOM' and the mutual significance of each domain, etc., and then self-evaluate, and according to the evaluated value, a number of symbols, for example, an asterisk (★), etc. are displayed.

The client 10 searches for the output domain list, and the client 10 can see the domains displayed in color on the domain list, and can know at a glance whether the domain is registered or unregistered. In addition, by looking at the indicator of the evaluated value according to the new highest extension that is to be used, the significance of the domain is determined.

Subsequently, after retrieving the list of domains displayed by category, the client 10 displays 'Get It!' On an unregistered domain, for example, the domain list. Click to select a domain to be registered from among those displayed in blue with a mark (S9).

When an unregistered domain is selected by the client 10, the number of selected domains is automatically inserted into the cart.

If the client 10 selects the domain 'Altavista' with the extension 'ORG' and the domain 'Coupon' with the extensions 'NET' and 'ORG' from the list of domains that have been traded at a high price, the selected extension of the domain The number of matches is displayed as '1' and '2' in Cart respectively.

When the client 10 requests the registration of the domain inserted into the cart, the web server 30 outputs the status and cost of the domain requested to the registration to the web browser of the client 10, and the client 10 registers the registration. The list of domains that have been clicked is displayed and displayed on the screen together with the registration fee and automatically settled (S10 to S11).

At this time, payment is made so that the domain registration fee is automatically settled according to the choice of credit card payment or direct deposit, etc. registered at the time of membership registration by the client.

In the present invention, when the client 10 first registers by a program that applies the concept of one-click shopping mall without inputting personal information and credit card number for each domain registered as in other domain registration systems. You can register a domain only with the information (personal information and credit card information, etc.) stored in the member DB by registering.

On the other hand, the client 10 who wants to search a domain other than the category displayed on the monitor clicks the search key L on the domain search engine in FIG. 4 and inputs a key keyword of the domain to search for registration of the domain. Can be.

Referring to FIG. 8, a case in which the client 10 wants to trade and exchange registered domains is referred to as a domain sales request, lease request, and free donation by establishing communication between clients through the shared memory of the web server 30. The client inputs the intention of ownership of the domain into the operator's server, and allows the other client to search for posts related to the domain sale of the other client while viewing the latest updated information on the operator's server 30 on his PC. . In other words, enter the domain name that you want to request for domain sales, lease request, and free donation in the domain name column, display the desired domain extension, click Find, and then real-time domain sales between clients through peer-to-peer function. Allow referrals, lease requests, and free donations.

In addition, the domain sale related inquiries retrieved from other clients 10 can be displayed on the domain sale related intention, and the client's intention is input back to the web server 30 of the operator, and the change is reflected on the next page. So that the domain owner (other clients) can be identified. To this end, the web server enables escrow service (S12 ~ S13).

Looking at another embodiment of the present invention with reference to Figure 3b as follows.

Clients who have subscribed to a member list search for a domain list database divided into categories consisting of domain names that are judged to have a proven economic value on the web. After generating and displaying a domain list, the client searches a displayed domain list and selects a domain to be registered among unregistered domains (S15 to S18).

When the client requests the registration of the domain selected from the domain list for each category, the web server 30 displays and pays the status and cost of the domain requested for registration (S19 to S20).

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention is not limited to the contents described in the accompanying drawings and the detailed description of the specification.

As described above, according to the present invention, the new top-level domain, which is not yet determined, is reviewed in advance in the DB of the extension name and the mutual significance of the domain, and displayed according to the importance of each, but stored directly on the client's PC to edit By doing so, the user can eliminate the hassle of having to search for important keywords again.

In addition, the present invention can search not only arbitrary word search, but also the highly recognized domains already verified in the market with basic data, and above all, easily solve the difficulty of domain search and registration due to the explosive increase in domain demand and extension name. can do.

In addition, the present invention when the desired domain is searched by sharing information related to cross-domain sales between the clients, it is possible to see the sales information of the domain, when the deposit through the card payment system, the operator changes the domain And escrow function by sending the deposit to the seller.

In addition, it searches for unregistered domains among important domains and client domains that are judged to be valuable and databases that are arbitrarily determined, and introduces the concept of a shopping mall in the domain registration process so that payment can be made with only one pre-registration. There is an excellent effect to realize a user-centered interface.

In addition, at least 100 domains and 10 or more extension names (top-level domains) can be searched at the same time, and the search results indicate whether the domain is registered at a glance by displaying whether registered or unregistered.
