[0058] File encryption module: used to encrypt and save electronic files through file encryption technology.

[0059] The specific steps of the file encryption technology are as follows:

[0060] S21. The archive system manager uses the access policy to encrypt the electronic archive and output the ciphertext data, and stores the ciphertext data in the archive management system;

[0061] S22, the archive management system authenticates all users and user authority organizations in the system, generates user identifiers, performs authority collection on the authority corresponding to the user, and generates archive keys;

[0062] S23, the authenticated user authority generates its corresponding authority key;

[0063] S24. The user generates a user private key by submitting the user's identifier, the authority key, and the user's authority set to the user authority agency corresponding to the user;

[0064] S25. When the user needs to decrypt, the user sends a decryption request to the archive management system, and the archive management system sends the ciphertext data to the user. The user inputs the archive key, ciphertext and user private key into the archive management system for decryption.

[0065] Archive access module: used to verify the user's identity, obtain access rights to electronic archives based on the user's identity, record the user's browsing, borrowing, modification, and deletion operations on electronic archives in the system, generate user logs based on the user's operations, and audit the user logs.

[0066] Users can borrow paper archives through the archive access module. When users return paper archives within the specified period, they can verify their identities through the archive access module and recognize the QR code of the paper archive through the QR code reader in the archive collection module to achieve rapid archiving of paper archives.

[0067] The user log is reviewed, wherein the user's borrowing behavior is evaluated and reviewed, as shown below:

[0068]

[0069] Wherein, Z is the frequency of user borrowing, A and B are the standard deviation and mean of the time interval distribution of user borrowing respectively; the value range of Z is [-1,1], when the value of Z is closer to -1, it means that the user has regular borrowing behavior; when the value of Z is closer to 0, the values ​​of A and B are closer, which means that the user rarely does not borrow for a long time; when the value of Z is closer to 1, the difference between A and B is larger, which means that the user is prone to have a long time interval between borrowing; the user's borrowing time interval is judged to evaluate and audit it.

[0070] Automatically set automatic backup strategies, regularly back up electronic archive data, ensure the long-term storage and integrity of electronic archive data, and have archive recovery functions to prevent data loss caused by inevitable failures in the archive system. The archive backup module can quickly restore archive information and minimize losses. It can effectively respond to various emergencies and ensure the reliability of electronic archive data.
