Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to the data sharing system shown in fig. 1, the data sharing system 100 refers to a system for performing data sharing between nodes, the data sharing system may include a plurality of nodes 101, and the plurality of nodes 101 may refer to respective clients in the data sharing system. Each node 101 may receive input information while operating normally and maintain shared data within the data sharing system based on the received input information. In order to ensure information intercommunication in the data sharing system, information connection can exist between each node in the data sharing system, and information transmission can be carried out between the nodes through the information connection. For example, when an arbitrary node in the data sharing system receives input information, other nodes in the data sharing system acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all the nodes in the data sharing system are consistent.
Each node in the data sharing system has a node identifier corresponding thereto, and each node in the data sharing system may store a node identifier of another node in the data sharing system, so that the generated block is broadcast to the other node in the data sharing system according to the node identifier of the other node in the following. Each node may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the node, and table 1 only illustrates the IP address as an example.
Each node in the data sharing system stores one identical blockchain. The block chain is composed of a plurality of blocks, referring to fig. 2, the block chain is composed of a plurality of blocks, the starting block includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.
When each block in the block chain is generated, referring to fig. 3, when the node where the block chain is located receives the input information, the input information is verified, after the verification is completed, the input information is stored in the memory pool, and the hash tree for recording the input information is updated; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:
SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))＜TARGET，
wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.
Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. And then, the node where the block chain is located respectively sends the newly generated blocks to other nodes in the data sharing system where the newly generated blocks are located according to the node identifications of the other nodes in the data sharing system, the newly generated blocks are verified by the other nodes, and the newly generated blocks are added to the block chain stored in the newly generated blocks after the verification is completed.
Therefore, the contents in the blocks in the blockchain are related, and the same blockchain is stored in each node of the blockchain system, so that once the blocks in the blockchain are created, the contents in the blocks cannot be modified, and the security of the data in the blocks in the blockchain can be ensured.
Referring to fig. 4, fig. 4 is a diagram of a network architecture 400 of the present application, which includes a server 410, a terminal 420, and a communication link 430. The terminal 420 and the server 410 may communicate via a communication link 430.
Referring to fig. 5, fig. 5 is a schematic diagram of a hardware structure of a server 410 according to an embodiment of the present disclosure. The server 410 includes a processor 411, a memory 412, a communication interface 413, and one or more programs stored in the memory 412 and configured to be executed by the processor 411, the programs including instructions to perform the steps of the tax data processing method of any of the following embodiments. Memory 412 includes Random Access Memory (RAM), and disk storage. Communication interface 413 may optionally include a standard wired interface, a wireless interface (e.g., a WI-FI interface).
The terminal 420 may be, for example, but not limited to, a mobile phone, a smart band, a tablet computer, a notebook computer, etc.
In order to ensure data security, the tax department may store tax data in each block of the block chain. The tax data may be, for example, invoice data. For example, when the tax management system generates an electronic invoice, a new block may be created in the block for storing the invoice information of the electronic invoice. Therefore, the data in the blocks of the block chain are difficult to modify, so that the safety of the invoice information can be ensured, and the invoice information is prevented from being modified. However, this also brings about some problems. The tax management system also needs to count and analyze the tax data to form a visual chart, and the visual chart is displayed at the terminal so that the staff can monitor the tax data conveniently. If data is acquired from the blockchain each time the visualization chart is updated, this may cause a lag in updating the visualization chart.
In order to solve the technical problem, the application provides a tax data processing method, and when a server detects that a block chain has updated tax data, the updated tax data is synchronized to a central database of a tax management system. That is, a plurality of pieces of tax data are stored in the central database, and the tax data in the central database is synchronously updated according to the tax data in the block chain. Therefore, the terminal can form a visual tax data chart according to the tax data in the central database without acquiring the tax data from the block chain, so that the tax data chart can be updated more quickly, and the instantaneity of the tax data chart is ensured.
Referring to fig. 6, fig. 6 is a schematic flow chart illustrating a tax data processing method according to an embodiment of the present application.
601. The server detects the number of blocks in the block chain.
In the embodiment of the application, when the tax data is generated by the tax management system, the tax data is stored in the block chain, and a plurality of pieces of tax data are also stored in the block chain. For example, tax data may include invoice information. When the tax management system generates the electronic invoice, a new block can be created in the block for storing the invoice information of the electronic invoice. The server is a server with access rights to the blockchain, and may be a server of a tax management system, for example.
If the block chain has the updated tax data, the block is added. Then the presence of updated tax data in the blockchain may be detected by detecting the number in the blockchain.
Specifically, the server may detect the number of blocks in real time. That is, the operation of detecting the number of blocks in the block chain is repeated a plurality of times. For example, the server may detect the number of tiles in the tile chain at a first time interval. The first time interval may be, for example, but not limited to, 1s, 0.8s, 0.5s, etc. Thus, the first time interval is less than or equal to 1s, and the tax data updated in the block chain can be detected more timely.
Specifically, the server may compare a first height of the block chain with a second height of the central database, and determine whether the first height is consistent with the second height, where each block in the block chain corresponds to a block height, and a block height corresponding to a block with a later creation time is greater than a block height corresponding to a block with an earlier creation time, where the first height is a maximum block height among block heights corresponding to blocks of the block chain when the detection is performed this time, and the second height is a maximum block height among block heights corresponding to blocks of the block chain when the central database is updated last time; and when the first height is not consistent with the second height, confirming that the block chain has a new block.
It will be appreciated that each tile in the chain of tiles corresponds to a tile height, which is generated when the corresponding tile is created. The earlier the block creation time is, the smaller the block height is; the later the block creation time, the greater the block height. Then, the larger the block height, the later the update time of the tax data stored in the block. The first height is the largest block height among the block heights corresponding to the blocks of the block chain in the current detection, and then the block corresponding to the first height is the newly created block. The second height is the maximum block height among the block heights corresponding to the blocks of the block chain when the central database is updated last time, that is, the maximum block height among the block heights corresponding to the blocks of the block chain when the server updates the tax data is stored after synchronizing the updated tax data into the central database of the tax management system each time. In this way, the second height may reflect the time when the central database was last updated. Since the blocks in the block chain can only be added and can not be deleted. Therefore, whether new blocks are added in the block chain after the central database is updated last time can be judged by comparing the first height with the second height, namely whether updated tax data exists in the detection block chain is detected. When the first height and the second height are different, it can be confirmed that there is a new block in the block chain after the central database is last updated. If the first height and the second height are the same, it can be confirmed that there is no new block in the block chain after the central database is updated last time.
Therefore, whether a newly added block exists in the block chain can be detected quickly and accurately to determine whether the newly added tax data exists in the block chain, and the tax data of each block in the block chain does not need to be compared with the tax data in the central database.
Further, the server may detect the number of blocks in the block chain by using a first process according to a first preset time interval, where the first process is independent from a second process, and the second process is a system process of the tax management system. Therefore, the server detects whether the newly added block exists in the block chain by using the first process independent of the system process, so that the tax data in the newly added block in the block chain can be more quickly synchronized to the central database, and the real-time performance of the tax data in the central database is ensured.
The server can also detect whether the first process is abnormal or not, and restart the first process when the first process is abnormal. Therefore, the server can monitor the running state of the first process in real time and restart the first process when the first process is abnormal so as to ensure that the first process can normally detect whether a block chain has a newly added block.
602. When detecting that a new block exists in the block chain, the server updates a central database of the tax management system according to the tax data in the new block, wherein a plurality of tax data are stored in the central database.
And the server synchronizes the tax data in the newly added blocks into a central database of the tax management system every time the server detects that the newly added blocks exist in the block chain. It will be appreciated then that the tax data stored in the central database is updated as the tax data in the blockchain is updated. Thus, the tax data stored in the central database is substantially synchronized with the tax data in the blockchain.
Specifically, when detecting that updated tax data exists in the block chain, the server synchronizes the tax data stored in the block with the block height greater than the second height in the block chain to a central database of the tax management system. And the tax data stored in the block with the block height larger than the second height is the updated tax data in the block chain when the central database is updated last time and the updated tax data in the block chain is detected this time.
Therefore, the tax data to be synchronized is directly determined according to the block height, the updated tax data can be synchronized to the block chain more conveniently and quickly, the tax data in each block does not need to be compared with the tax data in the central database, and the data to be synchronized is determined according to the time stamp after the time stamp of each block in the block chain is read.
603. The terminal sends a data reading request to the server.
The tax management system can display the tax data chart through the terminal. When the terminal needs to update the tax data chart, the tax data needs to be acquired from the central database. The terminal may then send a data read request to the server.
Specifically, the terminal can access a target web page corresponding to the tax management system to display a tax data chart. And the terminal refreshes the tax data chart at the target web page according to a second time interval, wherein the first time interval is smaller than the second time interval. Therefore, the tax data chart can be updated each time the terminal refreshes the tax data chart, and the situation that the terminal reads tax data from the central database but does not read new tax data to cause resource waste and cause update lag of the tax data chart is avoided.
604. And the server sends an access granting instruction to the terminal, wherein the access granting instruction is used for indicating the terminal to access the updated central database, so that the terminal updates the tax data chart of the target page according to the updated central database.
The server allows the terminal to access the updated central database so that the terminal can read the latest tax data.
The server can send an access grant instruction to the terminal after verifying the access right of the terminal. Specifically, the data reading request sent by the terminal may carry a user identifier, and after the server confirms that the user corresponding to the user identifier has the access right of the central database, the server sends an access grant instruction to the terminal.
Further, each piece of tax data includes data characteristic information. The server can classify and count a plurality of tax data in the central database according to the data characteristic information of each tax data in the updated central database; when a server receives a data reading request sent by a terminal, the terminal is allowed to access the classified and counted multiple pieces of tax data, so that the terminal can update the tax data chart of a target page according to the classified and counted multiple pieces of tax data.
605. And the terminal updates the tax data chart of the target page according to the updated central database.
For example, the data characteristic information may include regional information and data source organization information. The server classifies and counts a plurality of tax data according to the regional information of each tax data to obtain first counting data; and classifying the plurality of tax data according to the data source organization information of each tax data to obtain second statistical data. Therefore, the terminal can read the first statistical data, generate a regional classified tax data chart, read the second statistical data, generate a source classified tax data chart, and display the regional classified tax data chart and the source classified tax data chart on the terminal. When the tax data is invoice data, the regional classified tax data chart may be a chart in the form shown in fig. 7, and the source classified tax data chart may be a chart shown in fig. 8.
Certainly, the data feature information is not limited to the region information and the data source organization information, and may further include more data feature information, the server may generate different statistical data according to different data feature information, and the terminal reads different statistical data to generate different classified tax data charts. The terminal can show multiple classification tax data chart like this for tax data's visual chart is abundanter, and visual effect is better, is convenient for carry out tax management's staff's control tax data more.
In the technical scheme of the embodiment of the application, the server detects the number of blocks in a block chain; when detecting that a newly added block exists in the block chain, updating a central database of the tax management system according to tax data in the newly added block, wherein a plurality of tax data are stored in the central database; and when a data reading request sent by a terminal is received, sending an access granting instruction to the terminal, wherein the access granting instruction is used for indicating the terminal to access the updated central database, so that the terminal updates the tax data chart of the target page according to the updated central database. Therefore, when the terminal updates the tax data chart, the latest tax data can be read from the central database, and the tax data information does not need to be read from the block chain, so that the tax data chart can be updated more quickly, the instantaneity of the tax data chart displayed by the terminal is ensured, and a worker who performs tax management can monitor the tax data more accurately through the tax data chart. The tax data chart may better provide an important reference for the operation of blockchain electronic invoice services when the tax data is an invoice.
In some embodiments, the user may select the target area range by operating the terminal, so that the terminal generates the tax data chart for the tax data corresponding to the target area range selected by the user.
For example, in the example shown in fig. 9, a target page 900 of the terminal is displayed with a map 901, and the user can select a target area range by operating the terminal to select a region on the map. And after acquiring the target area range, the terminal sends a data reading request to the server, wherein the data reading request comprises the target area range. The server can allow the terminal to access one or more pieces of target tax data corresponding to the target area range.
Referring to fig. 9, the terminal may display a plurality of tax data graphs obtained according to the characteristic data information on the target page, so that the tax data graphs obtained through statistics from multiple angles are displayed on the same page, and the tax manager can know statistics of the tax data from multiple angles, thereby monitoring the tax data more accurately. And the terminal refreshes the chart according to the second time interval, so that the terminal can provide the dynamically updated chart on the target page, the display effect has more visual impact, the data is rich in dynamic sense, the real-time change condition of the data can be reflected, and the large-screen display and the external propaganda are facilitated.
Specifically, the server may obtain one or more pieces of target tax data corresponding to a target area range selected by the user from the multiple pieces of tax data in the central database according to the data characteristic information of each piece of tax data in the central database; performing regional classification statistics on the one or more target tax data according to the regional information to obtain first statistic data; and performing regional classified statistics on the one or more pieces of target tax data according to the information of the data source mechanism to obtain second statistical data. When a data reading request sent by a terminal is received, a server sends an access granting instruction to the terminal, and the access granting instruction is used for indicating the terminal to access first statistical data corresponding to the target area in the first statistical data and second statistical data corresponding to the target area in the second statistical data, so that the terminal updates a first tax data table of a target page according to the first statistical data and updates a second tax data table of the target page according to the second statistical data. Therefore, the user selects the target area according to the requirement, and the terminal displays the tax data chart reflecting the tax data of the target area.
Further, when the server receives a data reading request sent by the terminal, since the first statistical data is statistically classified according to regions, and the statistical classification result is the tax data volume of each region, the server can screen out the first statistical data corresponding to the target region in the first statistical data according to the target region. For example, if the target area is the Guangdong province, the server directly screens out the statistical data of the Guangdong province from the first statistical data to obtain the tax data volume of each region of the Guangdong province. The second statistical data is statistically classified according to the information of the data source institution, the obtained statistical classification result is the tax data from each institution, and then the server can screen out the tax data from each institution in the second statistical target area on the basis of the second statistical data to obtain second statistical subdata. Therefore, the terminal can generate the first tax data table according to the first subdata more quickly, and when the second tax data table is generated according to the second subdata, the terminal does not need to further screen data, so that the data processing amount of the terminal is reduced.
Referring to fig. 10, an embodiment of the invention further provides a tax data processing apparatus 1000, including:
a block detection module 1001 for detecting the number of blocks in a block chain;
an updating module 1002, configured to update a central database of the tax administration system according to tax data in a newly added block when the newly added block is detected in the block chain, where multiple pieces of tax data are stored in the central database;
the data processing module 1003 is configured to send an access grant instruction to the terminal when receiving a data reading request sent by the terminal, where the access grant instruction is used to instruct the terminal to access the updated central database, so that the terminal updates the tax data chart of the target page according to the updated central database.
The tax data processing device of the embodiment of the application detects the number of blocks in a block chain; when detecting that a newly added block exists in the block chain, updating a central database of the tax management system according to tax data in the newly added block, wherein a plurality of tax data are stored in the central database; and when a data reading request sent by a terminal is received, sending an access granting instruction to the terminal, wherein the access granting instruction is used for indicating the terminal to access the updated central database, so that the terminal updates the tax data chart of the target page according to the updated central database. Therefore, when the terminal updates the tax data chart, the latest tax data can be read from the central database, and the tax data information does not need to be read from the block chain, so that the tax data chart can be updated more quickly, the instantaneity of the tax data chart displayed by the terminal is ensured, and a worker who performs tax management can monitor the tax data more accurately through the tax data chart. The tax data chart can better provide important reference for the operation of the block chain electronic invoice business.
