File management system based on encryption and authentication mechanism

Abstract

The invention relates to the technical field of file security management, and discloses a file management system based on an encryption and authentication mechanism. The system comprises a file encryption and authentication management application program installed and operated on an operating system of a computer terminal, the file encryption authentication management application program comprises a user registration module, a user verification module and a file encryption module; before the file is stored, the file encryption module encrypts the file to obtain an encrypted file, and the encrypted file is stored on a hard disk of the computer terminal; before the encrypted file is accessed, the user verification module verifies the access authority of the file operation user, after the access authority of the file operation user is successfully verified, the encrypted file is decrypted on the file encryption module, and only the decryption operation of the encrypted file is successful, the file operation user is allowed to access the decrypted file. According to the invention, the technical problem of how to improve the file management security on the computer is solved.

Description

technical field [0001] The invention relates to the technical field of file safety management, in particular to a file management system based on an encryption and authentication mechanism. Background technique [0002] Information security for personal computers focuses on the management of information inside personal computers. Encrypting important files is a common information management strategy. Therefore, using an effective information encryption strategy is of great significance to the security of personal computers. There are generally two traditional file encryption methods: one is to use the encryption function of the application software itself to encrypt the file, such as Word, Excel, Access, WPS, and PDF files all have their own encryption function. This encryption method is easy to operate and is a commonly used file encryption method. But its disadvantage is that it can only encrypt and decrypt files in some formats. The other is to use the encryption func...
