Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
As shown in fig. 1, an embodiment of the present invention provides a result evidence storage method based on a federation chain, including the following steps:
s1, determining bottom layer parameters, rules and alliance chain nodes of an alliance chain, and building the alliance chain; the federation chain node comprises a first node, a digital identity authentication center and a plurality of second nodes; and the first node and the second node both store block data of the whole alliance chain, and each block data comprises a data index of the achievement information and a hash value of the achievement information. Fig. 2 is a schematic structural diagram of a federation chain built in the embodiment of the present invention.
In the step S1, the initially established alliance chain may further include a third node, where the third node is configured to store the block data uploaded by the second node, and is further configured to implement an inquiry operation of a node user, and generate a corresponding electronic score sheet after the verification is passed.
In this embodiment, the difference between the three types of nodes is that the first node may be configured to implement authorization of the second node and the third node, the second node may be configured to generate block data to be uploaded according to a score to be stored, and the third node is only configured to perform operations such as query and verification of the score. In addition, the score to be stored is only stored in the second node, and when the first node needs to acquire the score, the second node sends the score to the first node.
Before a alliance chain is built, department units corresponding to a first node and a second node are determined. In this embodiment, the first node may be a higher level executive education department, and the second node may be each school capable of uploading scores. The underlying parameters and rule settings (e.g., block size, data index, score information type and type, block ordering, etc.) in the federation chain are determined by a superior education department, such as the provincial or educational hall.
And S2, authorizing and authenticating the identity of each node through a digital identity authentication center.
The digital identity authentication center (such as Shanghai CA authentication center) authorizes and authenticates the identity of each node (including the first node, the second node or the third node) and provides digital identity authentication and management service. Before the identity of the second node is authorized through the digital identity authentication center, the second node needs to be authorized through the first node.
S3, the second node creates a data index for the score information needing to be linked, and calculates the hash value of the score information by adopting a hash encryption algorithm; and after the hash values of the data index and the achievement information are digitally signed and then packaged to generate new block data, broadcasting the new block data to each node in the alliance chain, and updating the block of the node.
Fig. 3 is a schematic diagram of data indexing in the present embodiment. The preprocessing before the result chaining specifically means that according to the existing teaching process links of colleges and universities, the results submitted by teachers are stored in a server of a teaching system, data indexes are created for relevant information such as performance generated by the department needing to chain, the hash values of the student performance information needing to chain are calculated by using a hash encryption algorithm, the relevant information such as performance generated by the department is shown in a table 1, and the corresponding relation between the data indexes and the hash values of the performance information is shown in a figure 3.
TABLE 1 selection of Ready-to-cochain score information and its Categories
Specifically, in step S3, after the second node performs identity authentication on the administrator, the second node creates an index of the data. In addition, other operations of the second node, including data chaining, performance interaction, etc., may also all be performed under the authority of the administrator.
S4, verifying the format and the signature of the new block by all nodes except for data uploading, and if the verification of one node fails, discarding the block by the node; if the verification is passed, each node updates the block data in the local node. The nodes that perform the verification and update of the block include a first node and other second nodes.
In step S4, if each node receives the block broadcasts of multiple nodes in a short time, the block sequence of the multiple nodes is configured according to a predetermined rule. The new block is uplinked as long as the other nodes check the correctness of the new block, the speed is higher, node design competing for accounting does not exist, the process that the new block is gradually confirmed does not exist, and the problem is solved according to a preset rule only when the ordering conflict of the new block is accepted.
The other nodes verify the format and the signature of the new block, and the authorization of the Shanghai CA authentication center ensures that the signature of the new block cannot be forged by nodes except a sender, any node can verify the correctness of the signature, and the other nodes discard the block if the correctness verification of the new block fails; after the other nodes verify the correctness of the new block, the block data in the local node is updated, and if each node receives block broadcasts of a plurality of nodes in a short time (for example, 1 minute), the block sequence of the plurality of nodes is configured (for example, dictionary sound sequence ordering of node names) according to a preset rule.
In this embodiment, after the authorization of the digital identity authentication center, the operation of chaining the score information can be performed, and meanwhile, the data index and the score information hash value are appended with the digital signature of the administrator of the second node, which is used for storing and tracing the certificates of the operation and the personnel.
S5, when score data under a chain needs to be inquired, verified or audited, determining a data index corresponding to the score data, and acquiring hash values H corresponding to the data indexes on all nodes according to the data index 1 ~H n Meanwhile, calculating the Hash value H of the corresponding result information under the chain 0 And comparing all the hash values, if all the hash values are equal, proving that the verification is passed and the result is correct, otherwise, indicating that the hash values are tampered. The result information under the chain is stored in the corresponding second node for uploading data, H n Represents the corresponding hash value in the nth federation chain node, and n represents the number of nodes in the federation chain.
Specifically, when a node user queries, verifies and audits the correctness of the score data under the link, the data index is queried according to the retrieval field and the like, hash data of score information on all nodes is obtained according to the data index, hash values of relevant information such as the scores are calculated again according to the data index, and all the hash values are compared. If all the results are equal, the results are proved to be correct, otherwise, the results data of the educational administration system or the hash value of the results information stored by some nodes is falsified.
And S6, after the verification is passed, the corresponding second node generates an electronic score sheet containing the score information of the student and sends the electronic score sheet to the inquiry user.
In the step S6, after the node user passes the verification, the generated electronic achievement list further includes the hash value of the achievement information and the two-dimensional code corresponding to the electronic achievement list. In addition, the electronic transcript also includes a digital signature of the corresponding second node.
And S7, authorizing the new node to serve as a third node of the alliance chain, wherein the third node is used for storing the block data uploaded by the second node, realizing the query operation of the node user, and generating a corresponding electronic score sheet after the verification is passed.
In this embodiment, the third node may be another organization (e.g., provincial society, provincial science and technology, provincial statistics bureau, student communication network, employment unit, human resource broker, consulting organization, student performance data transaction party, other industry alliance chain nodes, etc.), and authorization of the third node needs to be granted by the first node.
In addition, after the third-party organization is authorized as the third node, the third node can execute the operations of verifying, updating and sequencing the correctness of the new block, realize score interaction and acquire the corresponding score after the verification is passed. In addition to this, more complex intelligent contracts can be executed, such as: after data desensitization, the student score can be regarded as a resource, so that the student score can be shared by third-party big data organizations for studying situation analysis, data analysis and data mining to obtain more useful information; or can be regarded as an asset after data desensitization and is subjected to achievement transaction with a third party; or used by alliance chains in other industry fields to fulfill commercial and cross-chain requirements.
