Virtual disk-based file protection system and method

Abstract

The invention discloses a virtual disk-based file protection system. The system comprises an outgoing manufacturing module, an outgoing packaging module and an outgoing executive module, wherein the outgoing manufacturing module is positioned at a transmitting end and used for compressing and encrypting outgoing files to acquire an outgoing encrypted file set and setting the using right of the outgoing files to acquire an outgoing right control file; the outgoing packaging module is positioned at the transmitting end and used for packaging the outgoing encrypted file set and the outgoing right control file to generate executable outgoing packaged files; and the outgoing executive module is positioned at a receiving end and used for verifying the outgoing right control file in the executable outgoing packaged files, decrypting and decompressing the outgoing encrypted file set to a virtual disk which is generated by an outgoing virtual disk driving module to acquire the outgoing files if the outgoing right control file passes the verification, and stopping operation if the outgoing right control file does not pass the verification. The protection level is improved by the virtual disk, and the outgoing files are easy to make, so that users can easily and conveniently use the virtual disk-based file protection system.

Description

technical field [0001] The invention relates to a virtual disk-based file protection system and method. Background technique [0002] In the application of existing file transmission and protection methods, the more commonly used methods are as follows: Sending company A uses the file sending terminal to make outgoing files for the files that need to be sent out. First, encrypt the file and then set the file designation. Control information such as opening the software, operating authority, verification information, and time limit is encrypted and recorded in a file, and then the file processed by the file sending terminal and the file sending terminal are sent to other enterprise B, and other enterprise B installs After setting up the file sending terminal and passing the authentication, the processed outgoing file can be decrypted and opened according to the previously specified software, and the file can be operated according to its permission setting. In this way, even ...
