File Encryption System and File Encryption Method

Abstract

A file encryption system and a file encryption method. The file encryption system is mounted on an operating system platform, including a database module, an encryption module, and an associated module; the database module creates a database file for storage under each drive letter of a computer hard disk The time when the file was marked as encrypted, the file name of the marked file, the full path of the marked file, and the file's confidentiality level; the association module is associated with the operating system to monitor the user's operation on the file, and generate corresponding instruction transmission according to the user's operation on the file To the encryption module; the encryption module receives the instruction, according to the instruction, the time when the file stored in the database file under the drive letter related to the user operation is encrypted, the file name of the encrypted file, and the full file path of the encrypted file And the confidentiality level of the file is operated, the confidentiality level of the file is calibrated, and the binding of the confidentiality information and the electronic file is realized at the same time, so that the confidentiality information of the electronic file is not lost during the transmission and copying process, and the security and controllability of the file are improved.

Description

technical field [0001] The invention relates to the field of network communication security, in particular to a file encryption system and a file encryption method. Background technique [0002] With the popularization of the network, network communication has been integrated into all aspects of production and life in contemporary society, and the security and confidentiality of communication information has gradually attracted people's attention. When the sender realizes file transfer through the network, the successfully sent file is also out of the control of the sender. It is difficult for the sender to restrict the use and dissemination of the sent file, so that the sender faces the abuse or maliciousness of the sent file risk of spreading. [0003] In order to solve the above problems, the prior art CN101826964A discloses an outgoing file security management system that supports collaborative work. The security management system realizes the tracking and control of o...
