FIG. 1 is a flow chart of a method of blockchain-based report data processing in accordance with an embodiment of the invention. As one embodiment of the present invention, as shown in FIG. 1, the report data processing method based on the blockchain is applied to a back-end node, and may include:
step 101, receiving a report generation request sent by a front-end node, wherein the report generation request carries authority information of the front-end node.
The back-end node (blockchain node) receives a report generation request sent by the front-end node (blockchain node), wherein the report generation request carries authority information of the front-end node, and the authority information can be user group identification and/or user group authority.
Step 102, calculating a first hash value of authority information of the front-end node, and acquiring the first hash value generated by the front-end node from the blockchain.
After receiving a report generation request sent by a front-end node, a back-end node hashes authority information of the front-end node, so as to calculate a first hash value, and then acquires the first hash value generated by the front-end node from the blockchain.
A blockchain is a chain of blocks one by one. Each block holds certain information which is linked in a chain according to the time sequence of their respective generation. This chain is kept in all servers, and the entire blockchain is secure as long as one server in the entire system can work. These servers, referred to in the blockchain system as blockchain nodes, provide storage space and computational support for the entire blockchain system. If the information in the blockchain is to be modified, it is necessary to sign consent of more than half of the nodes and modify the information in all the nodes, which are usually held in different subject hands, so it is an extremely difficult thing to tamper with the information in the blockchain. Compared with the traditional network, the blockchain has two main core characteristics: firstly, the data is difficult to tamper, and secondly, the data is decentralised. Based on the two characteristics, the information recorded by the blockchain is more real and reliable, and can help solve the problem that people are not trusted each other.
In the basic working process of the blockchain, when the node A transfers to the node B, the generated transaction information is broadcast to all effective nodes in the network in a P2P mode in the form of blocks, the nodes authenticate the blocks through a consensus mechanism, and when the correctness and the validity of the blocks are approved, the blocks are added into the existing blockchain of the network in sequence, and the transfer from A to B is completed. Because the information in the blockchain is agreed upon by the consistency of most nodes in the network, the information is not erasable and tamperable and all nodes can read and query the transaction information. Since the blockchain is independent of authentication and management of the central node, correct information can be transmitted on an unreliable network, and the risks of data leakage and authentication failure caused by the attack of the central node are prevented.
And 103, if the calculated first hash value is consistent with the first hash value obtained from the blockchain, calculating a second hash value of the authority information of the front end node and the authority information of the rear end node, and writing the authority information of the front end node, the authority information of the rear end node and the second hash value into the blockchain.
It should be noted that when the front end node sends a report generation request to the back end node, the authority information of the front end node is hashed, and the authority information of the front end node and the calculated first hash value are written into the blockchain.
And the back-end node compares whether the calculated first hash value is consistent with the first hash value obtained from the blockchain, if so, the front-end node authority information is not tampered in the transmission process, the front-end node authority information and the back-end node authority information are further calculated, the front-end node authority information, the back-end node authority information and the second hash value are written into the blockchain, and therefore the fact that the back-end node authority information cannot be tampered can be further guaranteed. If the authority information of the front-end nodes is inconsistent, the authority information of the front-end nodes is tampered in the transmission process, and the process is ended.
And 104, acquiring service data from the organization node, generating report data according to the service data, and returning the report data to the front-end node.
After the authority information of the front end node passes verification, the back end node acquires service data stored in the organization node (blockchain node), then generates report data according to the acquired service data, and returns the generated report data to the front end node, so that the report data is displayed on the front end node.
Optionally, the report generation request further carries a report query scope and a report requirement. Optionally, obtaining service data from an organization node, thereby generating report data according to the service data, including: sending a service data acquisition request to an organization node, wherein the service data acquisition request carries authority information of the front end node and authority information of the rear end node; receiving service data returned by the mechanism node; generating report data according to the report query range and the report requirement and based on the business data. In some embodiments of the present invention, a user may select a report query range and a report requirement in a page of a front end node, and after receiving service data returned by an organization node, a back end node generates report data according to the report query range and the report requirement and based on the service data, so as to satisfy a report generation requirement of the user.
As long as one blockchain node modifies the request content, the hash value is modified, so that the hash values of all nodes need to be modified, and if other nodes do not allow modification, the modification operation of the node fails.
In some embodiments of the present invention, the front end node calculates hash of authority information, report query scope and report requirement of the user, writes the hash value into the blockchain, correspondingly, after the back end node receives the report generation request sent by the front end node, calculates hash of the authority information, report query scope and report requirement of the front end node, compares whether the two hash values are consistent, if so, calculates hash values of the authority information, report query scope, report requirement and the authority information of the back end node, and writes the authority information, report query scope, report requirement and the authority information of the back end node of the front end node into the blockchain. If not, the process ends.
Optionally, generating report data according to the report query range and the report requirement and based on the service data includes: if the sensitive data exist in the service data, calculating a hash value of the sensitive data, and acquiring the hash value of the sensitive data from the block chain; and if the calculated hash value of the sensitive data is consistent with the hash value of the sensitive data acquired from the blockchain, generating report data according to the report query range and the report requirement and based on the service data. In some embodiments of the present invention, before generating report data, judging whether service data acquired from a mechanism node includes sensitive data, if yes, calculating a hash value of the sensitive data, comparing the calculated hash value of the sensitive data with a hash value of the sensitive data acquired from the blockchain, and if consistent, indicating that the sensitive data is not tampered in a transmission process, generating report data according to the report query range and the report requirement and based on the service data; if the data are inconsistent, the sensitive data are tampered in the transmission process, and the process is ended.
It should be noted that, the organization node hashes sensitive data (such as name, certificate number, payment account number, etc.) in the service data, and writes the hash value of the sensitive data into the blockchain to ensure the data security. Therefore, the embodiment of the invention adopts transparent transmission to the sensitive data in the service data in the transmission process, and ensures that the sensitive data is not intercepted and checked.
In the embodiment of the invention, identity verification is needed for checking the report data, so that the problem that the report data is unauthorized to check is solved, verification is needed for checking the sensitive data, and a mutual trust mechanism between systems is increased.
The client initiates a request for checking the report at the front end node, and the client passes through the front end node, the back end node, the mechanism node (bank, insurance company, etc.) and other blockchain nodes, and in the process, the authority information of the user, the report query range, the report requirement and other information pass through the layer-by-layer nodes to generate blockdata and put the blockchain data on the blockchain. And after each block chain node passes, the request information and the information of the node side are hashed to generate block header information, and the block header information is transmitted to the next block chain node so as to prevent the data from being tampered.
According to the various embodiments described above, it can be seen that the technical means of calculating the first hash value of the authority information of the front end node and obtaining the first hash value generated by the front end node from the blockchain, if the calculated first hash value is consistent with the first hash value obtained from the blockchain, calculating the second hash value of the authority information of the front end node and the authority information of the rear end node, and writing the authority information of the rear end node and the second hash value into the blockchain, solves the technical problem that the prior art lacks effective protection on the aspects of authenticity, tamper resistance, sensitive information privacy and the like of report data. The embodiment of the invention can ensure the non-tamper property, traceability and the like of the report data through the blockchain technology, provide reliable basis for subsequent payment, claim settlement, security and other services, save labor cost and time cost for transacting business, reduce error rate, ensure the control of the report data viewing authority and avoid the leakage of private data.
