Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions 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. Obviously, the described embodiments are only Some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In the existing personnel file management technology, the dual-track file storage method in which paper files and electronic files coexist is usually adopted, and there are potential security risks in file management. For paper files, there is a risk of loss and damage, and for electronic files, there are hidden dangers of virus intrusion and human tampering. Therefore, the embodiments of the present invention introduce blockchain technology to manage personnel files, and utilize the advantages of decentralization and non-tampering in the blockchain to make the personnel file management process open, transparent, supervised, and more secure.

Example 1

As shown in Figure 1, a blockchain-based personnel file management method mainly includes the following steps:

S11, adopt the hash encryption algorithm to encrypt the user's file to generate the Hash value of the file, and extract the content information corresponding to the Hash value;

S12. Create file information, encrypt the file information with the user's public key, and store the ciphertext of the file information in the blockchain, where the file information includes: the Hash value, the content information , the transaction address of the user.

The above method includes two processes: the generation of the file Hash value and the establishment of the file information. The purpose of generating the Hash value is to ensure the security of the personnel file and ensure that the personnel file cannot be altered artificially. The purpose of creating file information is to package the personnel files and store them in the blockchain, so that the personnel files can be managed systematically.

It should be noted that, in the above method steps, the file includes: the user's personnel file information and the creation time of the personnel file. The file for generating the Hash value is preferably a file copy file, and the content information is a summary of the file, including: user name, ID number, creation time of the personnel file, and the like. In the process of creating file information, the user's public key is generated according to the user's basic information. Each user is configured with a unique public-private key pair, which is used to encrypt and decrypt the file information. The basic information includes the user's name and ID number. The user's transaction address can be the only parameter used to identify the user, such as the user account. The file information also includes the information of the person who provided the file generator.

As shown in Figure 2, as a possible implementation, the method disclosed in this embodiment further includes a blockchain-based update method for personnel files, including:

S21, searching for all profile information of the user through the transaction address, and obtaining the last profile information in all the profile information;

S22, decrypt the last archive information by the private key of the user, and obtain the Hash value of the last archive information;

S23, adopting the hash encryption algorithm to encrypt the copy of the Hash value of the newly added archive material and the last archive information to generate a new Hash value, and extract the new content information corresponding to the new Hash value simultaneously;

S24. Create new file information, encrypt the new file information with the user's public key, and store the ciphertext of the new file information in the blockchain, where the new file information includes: the new Hash value, The new content information, the user's transaction address.

In the above method of updating the file, since the file is stored in the blockchain in the form of a hash value, it is necessary to encrypt the hash value in the new file material and the latest file information with a hash encryption algorithm to generate a new hash value when updating. , which not only ensures the continuity of the archives, but also encrypts the newly added archives to ensure the security of the archives. The newly added archive material used to generate the new Hash value is preferably a copy of the newly added archive material. The new profile information also includes the information of the person who provided the update profile of the profile generator.

The following is an example to illustrate the update process of the file. The file information of the first generated user is "A", and "A" contains the file's Hash value "a", content information, and transaction address. The file data that needs to be added is "w". When updating, decrypt A to get the Hash value "a", then encrypt the copy of "a" and "w" into a new Hash value "b", and extract the corresponding value "b". Corresponding new content information "x", then package "b", "x" and transaction address to generate new file information "B" and encrypt "B" on the chain, so that the file information "A" is included on the blockchain and file information "B", where "B" includes the most complete file information. The subsequent update process is analogous, and as the number of updates increases, the more file information contained on the blockchain will be.

As a possible implementation, the method disclosed in this embodiment also includes a method for querying archives:

S31. After receiving the file query request, query all the file information of the user through the user's transaction address.

As shown in FIG. 3 , on the basis of the file query method, as a possible implementation situation, the method disclosed in this embodiment is the file verification method:

S32: After the file management user receives the verification request, decrypt the file information through the user's private key to obtain the plaintext of the file information, and send the plain text of the file information to the authentication manager for comparison with the real file.

File verification is to ensure the authenticity and integrity of file content. Among them, the certification management party is the government administrative department that keeps paper personnel files.

The following is a further description of the process of file query and authentication in this embodiment following the foregoing examples. When querying and certifying files, you only need to query the last file information in the blockchain, that is to say, if the above blockchain includes both "A" and "B", you only need to find "B" to carry out The query and authentication of the file is enough, because "B" contains the most complete file information.

As shown in FIG. 4 , based on the above-mentioned management method for personnel files disclosed in this embodiment, this embodiment also provides a management system for personnel files based on blockchain, which specifically includes:

The hash encryption module is used to encrypt the user's file to generate the hash value of the file;

a content information acquisition module, used for extracting content information corresponding to the Hash value;

Among them, the personnel file generation department is mainly responsible for making personnel files and updating personnel files, the personnel file management department is mainly responsible for managing personnel files, and the units that query and authenticate mainly refer to the units that have the need to query personnel files. The four parties complete the interaction and management of personnel files through the personnel file management system.

Users need to fill in their basic information when registering in the personnel file management system. The basic information includes: user name, ID number. The public and private key configuration module of the personnel file management system generates the user's unique public key and private key according to the user's basic information.

The personnel file generation department obtains the user's file from the user, and uses the hash algorithm of the system's hash encryption module to generate the file's Hash value from the copy of the file, and extracts the content corresponding to the Hash value from the file through the content information acquisition module. information. The personnel file generation department packs the hash value, content information and the user's transaction address to generate the file information, then encrypts the file information through the encryption module, and stores the ciphertext of the file information into the blockchain.

When the user needs to update the file information, he can send the file to be updated to the personnel file generation department. The personnel file generation department finds the user's file information through the file information search module, and obtains the Hash value of the last file information, here The last profile information is the latest updated profile information. The personnel file generation department uses the user's private key to decrypt the last file information through the decryption module of the system to obtain the Hash value of the last file information. The personnel file generation department encrypts the new Hash value by encrypting the copy of the Hash value in the new file material and the last file information through the hash encryption module, and extracts the new content information through the content information acquisition module. Then use the encryption module to encrypt the new file information through the public key, and store the ciphertext of the new file information into the blockchain. The new profile information includes: the new HASH value, the new content information, and the user's transaction address.

When the inquiring and certifying unit needs to authenticate the user's file, the inquiring and certifying unit sends an authentication request to the personnel file management department through the launch module. After receiving the authentication request, the personnel file management department searches for the user's file information through the file information search module and decrypts it by decrypting it. The module uses the user's private key to decrypt the archive information to obtain the plaintext of the archive information. Then the personnel archives management department sends the plaintext of the archives information to the personnel archives management department through the transmitting module, and the personnel archives management department is responsible for comparing the plaintext of the archives information with the paper personnel archives, and sending the comparison results to the inquiry and certification unit.

It can be seen from the above method that a blockchain-based personnel file management method and system disclosed in the present invention have the following advantages:

1. The present invention introduces blockchain technology to manage personnel files to form a distributed, supervised, traceable and authenticated file network system, which helps to improve the security, convenience and credibility of files;
