Embodiment Construction

[0018] The invention proposes a file marking system, which can realize the control of the calibration of the confidential information of the electronic file, and complete the binding of the marking information and the electronic file, so that the marking information and the digital signature are not lost during the transmission and copying of the electronic file, and the improvement is improved. Security and control over files.

[0019] figure 1 It is a block diagram of an embodiment of the document encryption system of the present invention. In the example, as figure 1 As shown, the document encryption system 1 is mounted on an operating system platform, and includes a database module 11 , an encryption module 12 and an association module 13 . The database module 11 creates a database file under each drive letter of the computer hard disk to store the encryption information of the encrypted files. Even if the removable disk is separated from the host computer, the classifi...

Abstract

The invention provides a file encryption system and a file encryption method. The file encryption system is carried on an operation system platform and comprises a database module, an encryption module and a related module, wherein the database module establishes a database file under each drive letter of a computer hard disk to store time of encrypting a file, a file name of the encrypted file, a file full path of the encrypted file and a file encryption grade; the related module is related to an operation system to monitor the operation to the file by a user, generates a corresponding instruction according to the operation to the file by the user and transmits the instruction to the encryption module; and the encryption module receives the instruction, operates the time of encrypting the file, the file name of the encrypted file, the file full path of the encrypted file and the file encryption grade, which are stored by the database file under the drive letter related to user operation, according to the instruction to mark the encryption grade of the file, and meanwhile, realizes the binding between encryption information and an electronic file, so that the encryption information of the electronic file is not lost in a transmission and copying process, and the safety and the 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...
