File security management system applied to network and management method thereof

Abstract

The invention provides a file security management system applied to a network, which comprises server and a user which are connected through the network, wherein the server is provided with file encryption equipment and user biological characteristic receiving equipment; the server stores and transmits files encrypted by using user biological characteristics as keys to the user; the user is provided with user biological characteristic acquisition equipment and file decryption equipment; and the user decrypts the files transmitted by the server by adopting the user biological characteristics. The file security management system effectively solves the security management problem of the files in the network.

Description

Technical field [0001] The invention belongs to the field of file safety management and information encryption and decryption, and particularly relates to a file safety management system applied to a network and a management method thereof. Background technique [0002] At present, in the field of file security management, encryption and decryption mechanisms are mostly used. That is, the server encrypts and protects files through symmetric encryption or asymmetric encryption algorithms, while the user uses the corresponding key for decryption. The disadvantage is the security management of the key. Once the key is stolen, there is no security at all, and even if the key is not stolen, after others intercept the ciphertext, they can also obtain plaintext information through brute force cracking, which poses a greater security risk. [0003] Further, the prior art also introduces a verification mechanism, that is, the file is stored on the server. When the user wants to obtain the f...
