Fig. 2 is a signaling interaction diagram of a data storage method according to an embodiment of the present invention. The embodiment of the invention is realized by interaction among a block chain link point, a sequencing service node and an accounting node in a data storage system, wherein the operation on the block chain link point can be realized by a plurality of servers which are used as the block chain nodes in the data storage system, and target block chains are configured on the plurality of servers. The operations performed by the ranking service node may be performed by a server within the target blockchain as the ranking service node, and the operations performed by the accounting node may be performed by a server within the target blockchain as the ranking service node. Referring to fig. 2, the method includes:
201. and the block chain node receives a personnel information storage request.
In the embodiment of the invention, the personnel information storage request carries the abstract of the personnel information and the storage address of the personnel information. When the enterprise end needs to store the personnel information, the enterprise end sends a personnel information storage request to the block chain node, and the block chain node receives the personnel information storage request and acquires the abstract of the personnel information to be stored and the storage address of the personnel information based on the personnel information storage request.
The staff information is information of staff currently included in the enterprise corresponding to the enterprise terminal. The storage address of the person can be a storage path for storing the person information for the device at the enterprise end. The enterprise terminal can obtain the abstract of the personnel in advance through a preset encryption algorithm according to the information of the personnel, the enterprise and the monitoring organization. As shown in fig. 3, the summary of the person may be generated based on the following data: the identity of the person, the identity of the regulatory agency in the blockchain, the business identity of the business in which the person is located, the business name, the employee record of the person, the employee performance and/or the employee position, etc.
The preset encryption algorithm may be set based on needs, which is not specifically limited in the embodiment of the present invention. The identity of the person may be the name of the person, employee number, etc. In addition, as shown in fig. 3, the data for generating the summary may further include the gender, birth date, name of the regulatory agency, and the like of the person.
As shown in fig. 3, the preset encryption algorithm may be a one-way Hash (Hash) algorithm, through which a unique and irreversible digest can be obtained, and other people cannot reversely derive information of the person, the enterprise, and the regulatory organization from the digest of the person, and the obtained digest is different from the digest of any other information, thereby further ensuring the security and privacy of the information.
It should be noted that the enterprise end may establish a communication connection with the block link node through the human resource management system of the enterprise end, and send the personnel information storage request to the block link node.
202. And the block chain node sends the personnel information storage request to an endorsement node in the target block chain.
In the embodiment of the present invention, the plurality of block link nodes may obtain a node identifier of an endorsement node, and the block link node may send the personnel information storage request to the endorsement node based on the node identifier of the endorsement node. The intelligent contracts can be installed on a plurality of block chain nodes of the data storage system in advance, and the plurality of block chain nodes can execute the flow of data storage on the data storage system based on the intelligent contracts. In generating the intelligent contract, an endorsement node within the target blockchain may be specified, the plurality of blockchain nodes storing node identifications of the endorsement nodes.
In the embodiment of the present invention, the endorsement node may be a node and/or a block link point corresponding to a regulatory mechanism in the data storage system, that is, a node corresponding to an enterprise in which the person is located. The intelligent contract may be created by and sent to a block link point, which is validated when other block link points install and agree to the intelligent contract. It should be noted that, when a contract is created, an endorsement node in the target block chain may be specified in advance, and meanwhile, endorsement policy information corresponding to the intelligent contract is stored in an associated manner. Of course, the number of endorsement nodes may be plural. The intelligent contract is also correspondingly stored on the blockchain, so that the accounting node in the target blockchain executes the relevant process of data storage according to the intelligent contract.
203. And the endorsement node returns a storage response to the block link point based on the intelligent contract of the data storage system.
The storage response may endorse the endorsement node with a signature of the personal information storage request. As shown in fig. 4, the endorsement node verifies the staff information storage request based on an intelligent contract; and according to the verification result, endorsement signature is carried out on the personnel information storage request, and the endorsement signature is returned to the block chain node.
When the personnel information storage request meets a first preset condition, the endorsement node verifies the personnel information storage request; otherwise, the verification is not passed. The first preset condition includes but is not limited to: whether the block link point has storage authority or not, whether the personnel information storage request is legal information or not and the like. For the storage authority of the block chain node, the endorsement node may determine whether the identifier of the block chain node is the identifier of the block chain node having the storage authority based on the node identifier of the block chain node. For whether the personnel information storage request is legal or not, the endorsement node can judge whether the block link point sending the personnel information storage request is a disguised node or not, and when the block link point is a disguised node with storage authority, the endorsement node determines that the personnel information storage request is not legal information; when the block link point is not a masquerading node, the endorsement node determines that the personnel information storage request is legal information.
In one possible design, the endorsement node can acquire the signature of the block chain link point, compare the signature with the signature of the block chain node with the storage authority, judge whether the signature is matched with the signature of the block chain node with the storage authority, and determine that the block chain link point is the disguised node when the signature is not matched with the signature of the block chain node with the storage authority; when the matching is performed, the block link point is determined not to be a masquerading node.
In the actual technical process, the endorsement node may also install the intelligent contract, or obtain the intelligent contract of the data storage system, where the intelligent contract includes the above-mentioned determination logic for determining whether the staff information storage request meets the first preset condition. When the intelligent contract is executed, the endorsement node stores the personnel information to request parameters of the intelligent contract, inputs the intelligent contract and runs the intelligent contract. When the intelligent contract outputs that the personnel information storage request is legal, the endorsement node uses a private key of the endorsement node to sign the output result, and returns the signed output result as a storage response to the block link point.
It should be noted that the operations performed by the endorsement node may be implemented by a server in the target block chain as the endorsement node. The signature is encrypted by the endorsement node through a private key, so that even if the endorsement node returns the signature to the block link point or the endorsement signature is transmitted for multiple times subsequently, the information of the endorsement signature cannot be tampered, and the accuracy and the reliability of the information are ensured.
204. And the block link node sends the storage response of each endorsement node and the personnel information storage request to a sequencing service node in the target block chain.
As shown in fig. 4, the block link point obtains the node identifier of the ranking service node, and sends the personnel information storage request and the received storage response of each endorsement node to the ranking service node according to the node identifier.
205. When the sequencing service node receives the storage response of each endorsement node and the personnel information storage request, the sequencing service node sequences the personnel information storage request and sends the sequenced personnel information storage request and the storage response of each endorsement node to the accounting node in the target block chain.
The data storage system may currently have a plurality of personnel information storage requests, and the sequencing service node may sequence according to the sending time of each request, and submit the sequenced personnel information storage requests and storage responses corresponding to the personnel information storage requests to the accounting node.
In one possible design, as shown in fig. 4, when the sequencing service node completes the above sequencing and submitting process to the accounting node, the sequencing service node notifies the enterprise side, and the process may be: and the sequencing service node returns the processing result of the personnel information storage request. The sequencing service node may return the processing result to a block link point, and the block link point forwards the processing result to the enterprise terminal.
It should be noted that, when the blockchain is a federation chain, the accounting node may be a respective blockchain node in the target channel. The target channel is a channel associated with the block chain node, of course, the target channel is also associated with other block chain nodes, and the plurality of block chain nodes can realize personnel information sharing based on an intelligent contract.
206. And the accounting node judges whether the storage response of each endorsement node conforms to the endorsement policy information or not, generates a target block based on the personnel information storage request when each endorsement node conforms to the endorsement policy information, and adds the target block into a target block chain.
And the accounting node judges whether the storage response of each endorsement node meets the authentication condition according to the authentication condition indicated by the endorsement policy information, and when the storage response of each endorsement node meets the authentication condition, the storage response of each endorsement node is determined to meet the endorsement policy information. And the accounting node generates a target block according to the abstract of the personnel information and the storage address of the personnel information, and adds the target block into a target block chain. And when the storage response of each endorsement node does not meet the authentication condition, the accounting node does not perform the in-chain processing on the target block, and the process is finished.
It should be noted that the endorsement policy information includes a plurality of authentication roles, the plurality of authentication roles may verify each personal information storage request, and when the plurality of authentication roles pass the verification, the block link point may link the personal information. Wherein the authentication condition includes but is not limited to: the endorsement policy information comprises that all authentication roles pass the verification of the personnel information storage request, or the authentication roles with preset number in all authentication roles pass the verification of the personnel information storage request. The authentication role may be set based on needs, which is not specifically limited in the embodiment of the present invention, and the authentication role may be a plurality of endorsement nodes in the target block chain or one or more endorsement nodes specified in the plurality of endorsement nodes.
In a possible embodiment, the accounting node may decrypt the endorsement signature corresponding to each endorsement node through the public key of each endorsement node to obtain the verification results of the plurality of endorsement nodes. And when the plurality of verification results meet the authentication condition of the endorsement policy information, determining whether the storage response of each endorsement node meets the endorsement policy information.
Further, when the storage response conforms to the endorsement policy information, the accounting node generates a target block based on the abstract of the person information in the person information storage request and the storage address of the person information. The accounting node may add the digest of the person information and the storage address of the person information to the block of the target block, store the packing time of the target block, the hash value of the block, and the hash value of a block in the block chain into the block header of the target block, and generate the target block according to the block and the block header.
In the embodiment of the present invention, the block chain may include a plurality of block chains storing different information, the plurality of chains may store a plurality of types of data, and the different types of data may be stored in different block chains correspondingly. And the accounting node acquires the target block chain for storing the abstract of the personnel information and the storage address of the personnel information and adds the target block to the target block chain according to the sequence of the block in the target block chain.
The hash value of the chunk is used to identify the uniqueness of the chunk in the blockchain. In addition, the sequencing service node can also add the uploading time of the personnel summary, version information of the block required to meet the protocol and the like to the target block.
As shown in fig. 5, only the abstract and the storage address of the person are stored in the target block, and the detailed information of the person is not directly stored, so that other users cannot directly view the information of the person, the privacy of data is protected, and the abstract and the storage address occupy less space, thereby saving the block space occupied by the data and improving the space utilization rate.
Moreover, the data storage system may include a plurality of block chains for storing different information, for example, a block chain for storing information of personnel included in an enterprise, a block chain for storing news of an enterprise, and the like, so that a plurality of data can be shared among a plurality of block chain nodes of the data storage system, the applicability of data storage is improved, and the user experience is improved.
It should be noted that the step 204 and 206 are actually a specific implementation manner of a process in which the block link node submits the received storage response of each endorsement node and the personnel information storage request to the accounting node, and the accounting node generates the block merge chain. The implementation mode is actually a process that the sequencing service node sequences and the accounting node executes endorsement policy verification and merging into a chain.
In the embodiment of the invention, after receiving a personnel information storage request, a block link node firstly sends the personnel information storage request to an endorsement node, and submits a storage response of each endorsement node and the personnel information storage request to an accounting node; when the storage response of each endorsement node accords with the endorsement policy information, the accounting node links the target block, so that the information source is real and reliable, the data in the target block cannot be tampered randomly, and the safety and the correctness of the data are ensured.
In the application, when the abstract and the storage address of the personnel information are stored in the block chain, any block chain node in the data storage system can inquire the personnel information as required. The following is an introduction to the query process.
