Abstract

The invention discloses a method and system for preventing a file from being stolen. The method comprises the steps that reasonable segmentation of the file to be stored is conducted, a global environment secret key is generated by means of environment information of all equipment, each segment of the file is encrypted with the secret key, and all the segments of the file are stored in the equipment after being wrapped in a shell program; the equipment storing the segmented file judges whether request equipment and the equipment are located in the same environment when each segment of the file is to be acquired or opened, and the request equipment is considered to be safe and acquiring or opening operation can be allowed only when the request equipment and the equipment are located in the same environment. According to the method and system, the file stored in the equipment is safer, the complete file can not be acquired easily, it can be found out in time if external equipment operates the segments of the file illegally, and then normal acquisition and decryption of the segmented file are prevented.

Description

technical field [0001] The invention relates to the technical field of file security, in particular to a method and system for preventing file theft. Background technique [0002] With the advancement of science and technology, the security of files in computers or mobile devices has been increasingly threatened. The protection of important files such as policies, plans, and technologies has become a top priority for national governments, enterprises and institutions. Heavy. At present, the means and technical level of file theft such as information files between countries, technical files between enterprises, and other company direction strategies are also on the rise, and the protection strategy in terms of file security is particularly important. [0003] The emergence of rootkits poses a more serious threat to file security. This malicious software will obtain the highest authority of the system and return important files and information, and even destroy the system wit...
