The tax data chain can be an alliance chain formed by tax related departments in various places, and is used for storing bill data uploaded by various buyer terminals or seller terminals and ensuring the safety of the bill data. The purchaser information chain may be a private chain in which a plurality of purchaser information is stored, and the purchaser information stored in the chain is not disclosed, so that privacy and security of the purchaser information can be ensured. Optionally, the buyer information chain may be connected to a service node in the blockchain network, so as to provide corresponding buyer information for the taxing bureau inspectors, judicial authorities and financial auditors.
Based on the above data processing scheme, an embodiment of the present invention provides a schematic structural diagram of a data processing system, as shown in fig. 1 a. The data processing system shown in fig. 1a may comprise a buyer terminal 101, a seller terminal 102 and a node device 103 of a blockchain network, and the node device 103 may be any node device located in the blockchain network. The purchaser terminal 101 and the seller terminal 102 may be terminal devices such as a smart phone, a tablet computer, and a smart wearable device, and these terminal devices have functions such as network communication. The purchaser terminal 101 is a terminal device used by a purchaser, and the seller terminal is a terminal device used by a seller.
The purchaser may perform business transactions with the seller through the purchaser terminal 101, such as purchasing goods, catering consumption, internet traffic consumption, and the like. The seller terminal 102 may provide the purchaser with the billing data when the business transaction between the purchaser and the seller is ended. Alternatively, the seller terminal 102 may provide the ticket data to the purchaser by issuing a ticket data for each transaction; alternatively, multiple business transactions are aggregated together to produce a single billing datum. In other words, the number of target ticket data may be one or more.
For example, assuming that the purchaser makes 3 business transactions with the seller through the purchaser terminal 101, and purchases a notebook having a value of 5 yuan, a pen having a value of 10 yuan, and a pencil having a value of 2 yuan, respectively, the seller may provide three billing data to the purchaser: wherein, the note data of the notebook computer comprises the number, unit price, buyer information, seller information, etc. of the purchased notebook computer; the bill data about the pens includes the number of purchased pens, unit price, purchaser information, seller information, and the like; the bill data about the pencil includes the number of purchased pencils, unit price, purchaser information, seller information, and the like. In other embodiments, the seller may provide a ticket data for the purchaser, and the purchased goods information is displayed in the ticket data.
In one embodiment, after the seller terminal 101 provides the ticket data to the purchaser, the purchaser may view and save the ticket data through the purchaser terminal 101. Optionally, the purchaser terminal 101 displays a prompt message for receiving and storing the ticket data on the user interface, the purchaser may select a storage address for storing the ticket data with respect to the prompt message, and the purchaser terminal 101 stores the ticket data in the storage address selected by the user. The storage address may be any one or more of a local storage, a cloud storage, and a blockchain storage of the purchaser terminal 101. The block chain becomes a more common bill data storage address because of its non-tamper property.
For example, referring to fig. 1b, a schematic diagram of a user interface of a buyer terminal according to an embodiment of the present invention is provided, when the buyer terminal receives ticket data provided by a seller terminal, a prompt message for receiving and storing the ticket data may be displayed in the user interface. Also included in the user interface are a trigger 104 to view ticket data and a trigger 105 to store ticket data. If the purchaser clicks 105, a storage address selection interface may be invoked, which may include a plurality of storage addresses, such as a local C disk, a local E disk, a cloud storage, a block chain storage, and the like. Assuming that the user selects the blockchain storage, the purchaser terminal outputs notification information uploaded to the blockchain storage in the user interface according to the purchaser's selection as shown in fig. 1 c. The block chain may include a tax data chain specially used for storing the ticket data, and the tax data chain may be a federation chain, and the data stored in the chain is public, and if the buyer does not want the buyer information to be public, the buyer information included in the ticket data may be selected to be stored in an encrypted manner.
Optionally, in the user interface shown in fig. 1c, a trigger button 106 for storing the buyer information in an encrypted manner may be further displayed, and after the buyer clicks 106, the buyer terminal 101 may replace the buyer information in the ticket data with the target information identifier to obtain target ticket data; the target ticket data is then published to the blockchain network. In other embodiments, the purchaser terminal 101 may also generate an encrypted storage request according to a click operation of the purchaser, carry the ticket data in the encrypted storage request, send the encrypted storage request to the blockchain network, generate a target information identifier corresponding to the purchaser information by a node device of the blockchain network, and replace the purchaser information included in the ticket data with the target information identifier to obtain the target ticket data.
After acquiring target bill data, the node device 103 in the block chain network executes the data processing scheme, that is, the target bill data is sent to a tax data chain of the block chain network, so that the tax data chain stores the target bill data; and acquiring the buyer information from a buyer information chain of the blockchain network according to the target information identifier, and establishing an association relation between the buyer information and the target bill data.
Based on the data processing system, an embodiment of the present invention further provides a data processing method, and reference is made to fig. 2, which is a schematic flow chart of the data processing method provided in the embodiment of the present invention. The data processing method may be performed by any node device in the blockchain network, and may specifically be performed by a processor of the node device. The data processing method shown in fig. 2 may include the steps of:
step S201, obtaining target ticket data, where the target ticket data includes transaction data generated by the purchaser terminal and the seller terminal in the service transaction process and a target information identifier corresponding to the purchaser information.
The business transaction between the purchaser terminal and the seller terminal can be executed through a point-to-point payment channel between the purchaser terminal and the seller terminal, and the point-to-point payment channel is a transaction channel under a chain, so that compared with the business transaction executed on the chain, the business transaction executed by adopting the point-to-point payment channel has higher business execution efficiency. After the transaction is ended in the point-to-point payment channel, the settlement transaction is issued to the blockchain network according to the multiple business transactions of the purchaser terminal and the seller terminal, and the blockchain is responsible for transaction settlement. The business transaction may refer to a transaction of purchasing goods, lodging consumption, dining consumption, and the like. The transaction data may refer to the name of the item purchased, the quantity, the unit price, the total price, and so on.
In one embodiment, the target ticket data may be issued by a purchaser terminal into a blockchain network. Specifically, optionally, the purchaser terminal receives initial ticket data provided by the seller terminal, where the initial ticket data includes transaction data and purchaser information generated by the purchaser terminal and the seller terminal in the process of executing the business transaction. The transaction data may include names, quantities, prices, etc. of goods purchased by the purchaser, and the purchaser information may include names of purchasers, tax payment identification codes of the purchaser, etc.; if the buyer inputs a trigger operation of encrypting and storing the buyer information in a user interface of the buyer terminal, the buyer terminal acquires the buyer information included in the initial bill data and encrypts the acquired buyer information to obtain a target information identifier corresponding to the buyer information; then, replacing the buyer information in the initial bill data with a target information identifier to obtain target bill data; and finally, issuing the target bill data to the blockchain network.
In other embodiments, the target ticket data may also be generated by a blockchain network. Specifically, optionally, after the purchaser terminal receives the initial ticket number data provided by the seller terminal, the notification information of the received initial ticket data and the stored ticket data is displayed in the user interface, and the trigger button is further included for encrypting and storing the purchaser information; if the purchaser clicks a trigger button for storing purchase information in an encrypted manner, the purchaser terminal can send an encrypted storage request carrying initial bill data to the blockchain network; acquiring purchaser information in initial bill data by a block chain network, and encrypting the purchaser information to obtain a target information identifier; and replacing the buyer information in the initial bill data with the target information identifier to obtain target bill data.
Step S202, the target bill data is sent to a tax data chain of the block chain network, so that the tax data chain stores the target bill data.
In one embodiment, the blockchain network may include service nodes, the node device may be any one of the service nodes, the blockchain network may further include service nodes, and the tax data link may be a federation link composed of various local tax-related departments. The node equipment can send the target bill data to the service node, and the service node sends the target bill data to the tax data chain, so that the consensus node corresponding to the tax data chain performs consensus verification and storage on the target bill data.
In one embodiment, the number of tax data chains may be one or more, and each tax data chain may store one type of ticket data. It should be appreciated that categorizing different types of ticket data stores facilitates management of the ticket data and subsequent querying. Optionally, the target ticket data acquired by the node device may further include a target ticket type, and the sending of the target ticket data to the tax data link in the block link network includes: acquiring a tax data chain for storing target bill data according to the type of the target bill; and sending the target bill data to the acquired tax data chain. The bill type can comprise catering bills, office supplies bills, accommodation bills and other bills, and the target bill type can be any one of the above bills types.
In other embodiments, the number of the tax data chains may be one or more, and each tax data chain may store various types of ticket data. Optionally, the sending, by the node device, the target ticket data to the tax data link in the block link network includes: acquiring tax data chains for storing target bill data according to the block height of each tax data chain; and sending the target bill data to the acquired tax data chain. The method for acquiring the tax data chain for storing the target bill data according to the block height of each tax data chain may be as follows: acquiring the block height of each tax data chain; and taking the tax data chain meeting the preset block height condition as the tax data chain for storing the target bill data. The preset block height adjustable condition can refer to a block height threshold, and in each tax data chain, tax data chain storage target bill data with the block height smaller than or equal to the block height threshold is obtained; alternatively, the preset block height condition may refer to: and selecting the tax data chain with the smallest block height from the block heights as the tax data chain for storing the target bill data.
It should be understood that the above are only two exemplary ways to send target ticket data to the tax data chain according to the embodiments of the present invention. In practical application, an appropriate manner can be selected according to actual requirements, and is not limited to the two manners.
Step S203, acquiring the buyer information from the buyer information chain of the block chain network according to the target information identification, and establishing the association relationship between the buyer information and the target bill data.
In one embodiment, if the purchaser wants to store his own ticket data in the blockchain, the purchaser may upload his own purchaser information to the purchaser information chain of the blockchain network in advance through the purchaser terminal for storage, so that the subsequent blockchain network associates the target ticket data with the purchaser information stored in the purchaser information chain when acquiring the target ticket data of the purchaser, so that the purchaser information chain and the tax data chain are associated with each other for reconciliation. The buyer information chain is a private chain, information stored in the private chain cannot be disclosed, only a specified user can view the information, and the privacy of the buyer can be protected.
Optionally, the node device in the blockchain network obtains a storage request related to the buyer information, where the storage request includes the buyer information and a target information identifier corresponding to the buyer information; the node device sends a storage request to the purchaser information chain such that the purchaser information chain stores the purchaser information and the target information identification.
In one embodiment, the storage request may be issued by the purchaser terminal into the blockchain network, specifically, the purchaser inputs purchaser information through the purchaser terminal and inputs a trigger for uploading to the blockchain network encrypted storage; the purchaser terminal encrypts the purchaser information to obtain a target information identifier; and generating a storage request according to the target information identifier and the trigger operation of the purchaser, and sending the storage request to the block chain network.
In other embodiments, the storage request may also be generated by a blockchain network. Specifically, the purchaser inputs purchaser information and triggers the operation of encrypting and storing the purchaser information through the purchaser, and then the purchaser terminal issues the purchaser information to the block chain network; the block chain network encrypts the purchaser information to obtain a target information identifier corresponding to the purchaser information; and generating a storage request according to the target information identification and the buyer information.
It should be understood that, when the block chain network stores data, the data to be stored is subjected to hash processing to obtain a hash value corresponding to the data to be stored, and the hash value is stored in a block. The embodiment of establishing the association relationship between the buyer information and the target ticket data in the step S203 may be: acquiring a target hash value corresponding to the purchaser information on the purchaser information chain; and determining the target hash value as the hash value of the target information identifier. In short, the hash value of the ticket header in the target ticket is equal to the hash value of the corresponding purchaser information in the purchaser information chain.
In the embodiment of the invention, the node equipment of the block link network acquires the target bill data and sends the acquired target bill data to the tax data link of the block link network, so that the tax data link stores the target bill data, and the storage safety of the target bill data is ensured based on the non-tamper property of the block link. In addition, the target bill data acquired by the node device includes transaction data generated by the buyer terminal and the seller terminal in the process of executing business transaction and a target information identifier corresponding to the buyer information, and the target information identifier corresponding to the buyer information is carried in the target bill data instead of directly carrying the buyer information in the target bill data, so that the buyer information can be protected from being disclosed. In this case, in order to ensure the authenticity of the target ticket data, the node device obtains the buyer information from a buyer information chain of the blockchain network according to the target information identifier, and establishes an association relationship between the buyer information and the target ticket data. In this way, the authenticity of the target bill data can be verified subsequently through the association relationship between the two. In summary, the embodiments of the present invention can implement both the storage of the target ticket data in the blockchain network to ensure its security and the protection of the privacy of the buyer information.
Based on the above data processing method, an embodiment of the present invention further provides another data processing method, and referring to fig. 3, a schematic flow diagram of another data processing method provided in an embodiment of the present invention is shown. The data processing method shown in fig. 3 may be executed by a node device in a blockchain network, and may specifically be executed by a processor of the node device. The data processing method shown in fig. 3 may include the steps of:
step S301, target bill data is obtained, wherein the target bill data comprises transaction data generated by the purchaser terminal and the seller terminal in the process of executing business transaction and a target information identifier corresponding to the purchaser information.
Step S302, the target bill data is sent to a tax data chain of the block chain network, so that the tax data chain stores the target bill data.
Step S303, acquiring the buyer information from the buyer information chain of the block chain network according to the target information identifier, and establishing the association relationship between the buyer information and the target bill data.
In an embodiment, some possible implementations included in steps S301 to S303 may refer to descriptions of related steps in the embodiment shown in fig. 2, and are not described herein again.
Step S304, a change request about the buyer information is acquired.
Step S305, sending a change request to the buyer information chain for instructing the buyer information chain to change the stored buyer information and/or the target information identification based on the change request.
In one embodiment, the buyer information may include first attribute information and a first status of a buyer before modification, the buyer being any one of an individual user or an enterprise user; if the purchaser is an individual user, the first attribute information includes an identity for identifying the identity of the individual user, and the first state includes that the credit score of the purchaser is greater than a preset value or the credit score is not greater than a preset value; if the purchaser is an enterprise user, the first attribute information includes enterprise identification information for identifying the enterprise, and the first state includes a logout state or a business state.
The purchaser information may change over time, and if the purchaser is an individual user, the purchaser information change may refer to a change in the first attribute information, for example, the identification information of the individual user is expired, for example, the identification information is an identification card, and the expiration of the identification information may refer to the expiration of the validity period of the identification card; the purchaser information change may also refer to a first status change of the individual user, such as an increase or decrease in credit score. If the purchaser is a business user, the purchaser information change may refer to a change in the first attribute information, for example, a change in business identification information of the business, for example, the business identification information may be a business name, if the business name is changed, indicating that the purchaser information is changed; alternatively, the buyer information change may also refer to a first status change, such as the enterprise user changing from an open status to a logged off status, or from a logged off status to an open status.
In order to ensure the accuracy of the buyer information stored on the buyer information chain, the information of the buyer on the buyer information chain needs to be updated synchronously once the buyer information changes. In one embodiment, the change request may be generated and issued by the purchaser terminal to the blockchain network in step S304, or the blockchain network may be generated according to new purchaser information produced by the purchaser terminal.
In one embodiment, the buyer information stored in the buyer information chain may include first attribute information and a first state of the buyer before the change, and the change request includes one or more of second attribute information, a second state of the buyer after the change and a new information identifier, and the change request is sent to the buyer information chain for instructing the buyer information to change the stored buyer information and/or target information identifier based on the change request, including: if the second attribute information and the new identification information are included in the change request, the change request is used for instructing the buyer information chain to change the first attribute information into the second attribute information and change the target information identification into the new information identification; if the second state is included in the change request, the change request is used to instruct the purchaser information chain to change the first state to the second state.
As can be seen from the foregoing, the destination information identifier is obtained by encrypting the purchaser information by the purchaser terminal or the node device in the blockchain network, where the purchaser information may specifically refer to the first attribute information of the purchaser, and if the first attribute information included in the purchaser is changed into the second attribute information, the destination information identifier is also changed, and if the first state included in the purchaser is changed into the second state, the destination information identifier is not changed; alternatively, the purchaser information described herein may include first attribute information and a first status of the purchaser, in which case, if the first attribute information included in the purchaser is changed to second attribute information and/or the first status is changed to a second status, the destination information identification may be changed accordingly. In the embodiment of the present invention, the first case is described as an example.
Therefore, if the change request includes the second attribute information, it indicates that the first attribute information included in the purchaser information is changed, and at this time, the change request also carries a new information identifier obtained by encrypting the second attribute information, and at this time, after the purchaser information chain receives the change request, the first attribute information in the purchaser information stored in the purchaser information chain is changed to the second attribute information, and the target information is changed to the new information identifier. If the second state is included in the change request, it indicates that the first attribute information of the purchaser information is not changed, and only the first state is changed, and at this time, the purchaser information chain only needs to change the first state in the purchaser information to the second state.
In one embodiment, the tax data chain may also set access rights for the target ticket data when storing the target ticket data. If the second state is included in the change request, the first state indicates that the purchaser is a valid purchaser, and the second state indicates that the purchaser is an invalid purchaser, if it is detected that the first state included in the purchaser information on the purchaser information chain is changed to the second state, a second data change notification is initiated to the tax data chain, the second change notification being used for indicating that the tax data chain sets the access right of the target ticket data to be only visible to the tax manager. If the buyer is an individual user, the buyer can indicate that the credit score of the buyer is greater than a preset value for effective buyers and the credit score of the buyer is not greater than the preset value for ineffective buyers; if the buyer is an enterprise user, the buyer being valid may indicate that the enterprise is in an open state, and the buyer being invalid may indicate that the enterprise is in a logout state or a sealed state.
To summarize, when the purchaser is a valid purchaser, the access rights of the target ticket data associated with the purchaser information may be set to be visible to all users; when the purchaser is an invalid purchaser, the access authority of the target ticket data associated with the purchaser information may be set to be visible only to the tax manager, facilitating management of the tax data.
Step S306, if the target information identification on the purchaser information chain is detected to be changed, a first data change notice is sent to the tax data chain, and the first data change notice is used for indicating the tax data chain to change the target bill identification included in the target bill data into a new information identification.
In order to ensure the accuracy of the ticket data, once the target information identifier of the buyer information is detected to be changed, the target information identifier in the target ticket data needs to be updated synchronously. Specifically, if the target information identifier on the purchaser information chain is detected to be changed, a first data change notification is initiated to the tax data chain, and the tax data chain changes the target information identifier in the target bill data to a new information identifier indicated in the first data change notification.
For example, fig. 4 is a schematic diagram for associating the modified target information identifier with the target ticket data according to an embodiment of the present invention. In fig. 4, it is assumed that the creation block responsible for the tax data association in the block chain network hastens two block chains, one is a tax data chain and is responsible for executing tax control service; one is a purchaser information chain responsible for managing purchaser information. As can be seen from fig. 4, a plurality of pieces of ticket data, such as ticket data a, ticket data B, ticket data X, and ticket data Y, are stored in the tax data chain, and it is assumed that the ticket data X is the target ticket data. The purchaser information chain stores a plurality of purchaser information, such as corporate a information, business B information, corporate C information, and corporate D information.
It is assumed that, when the ticket data a, the ticket data B, and the ticket data Y are stored in the tax data chain, the buyer corresponding to the ticket data does not input the trigger operation of the buyer information encryption storage at the corresponding buyer terminal, and therefore, the ticket data includes the transaction data and the corresponding buyer information. If the purchaser corresponding to the ticket data X is a legal person C, and the legal person C inputs a trigger operation of encrypting and storing purchaser information when the ticket data X is stored, the ticket data C includes transaction data and a target information identifier of the purchaser information.
The billing data X is associated with corporate C information on the purchaser information chain. Assuming that the legal information C changes, the node device sends a notification to the tax data chain to cause the tax data chain to change the ticket data X. Assuming that the first state included in the information of the legal person C is a business state, if a change request of the information of the legal person C is detected, the change request indicates to change the first state into the second state, and the second state indicates that the legal person C is in a logout state. At this time, the node device sends a first data change notification to the tax data chain, and the visibility state of the ticket data X is changed by the tax data chain, as shown in fig. 4. Assuming that the information identifier corresponding to the legal person information C is changed from the target information identifier to a new information identifier, the node device sends a data change request to the tax data chain, and the tax data chain changes the target information identifier included in the ticket data X to the new information identifier (not shown in fig. 4).
In other embodiments, the buyer information chain may be externally connected to a buyer information query service, which may provide buyer information to tax authorities such as tax authorities or jurisdictions. Optionally, the buyer information chain may be a private chain, the block chain network may include a service node, the service node is configured to provide a query service for the buyer information stored in the facet information chain, and the node device interacts with the buyer information chain through the service node. Specifically, the node equipment acquires a query request aiming at the buyer information; the query request is sent to the service node to cause the service node to obtain the buyer information from the buyer information chain based on the buyer identification included in the query request.
In the embodiment of the invention, the node equipment of the block link network acquires the target bill data and sends the acquired target bill data to the tax data link of the block link network so that the tax data link stores the target bill data. In addition, the target bill data acquired by the node device includes transaction data generated by the buyer terminal and the seller terminal in the process of executing business transaction and a target information identifier corresponding to the buyer information, and the target information representation corresponding to the buyer information is carried in the target bill data instead of directly carrying the buyer information in the target bill data, so that the buyer information can be protected from being disclosed. In this case, in order to ensure the authenticity of the target ticket data, the node device obtains the buyer information from a buyer information chain of the blockchain network according to the target information identifier, and establishes an association relationship between the buyer information and the target ticket data. In this way, the authenticity of the target bill data can be verified subsequently through the association relationship between the two. In summary, the embodiments of the present invention can implement both the storage of the target ticket data in the blockchain network to ensure its security and the protection of the privacy of the buyer information.
Further, if a change request regarding the purchaser information is obtained, a change request is sent to the purchaser information chain for instructing the purchaser information chain to change the stored purchaser information and/or target information identification based on the change request. And sending a first data change request to the tax data chain to instruct the tax data chain to change the target information identifier included in the target bill data into a new information identifier once the change of the target information identifier corresponding to the buyer information on the buyer information chain is detected. Therefore, the synchronization of the buyer information and the target bill data can be kept at any time, and the accuracy of the target bill data storage is ensured.
