Problems solved by technology

In the prior art, people will store files in pre-divided reserved areas. This method improves the security of file storage to a certain extent, but due to the lack of reasonable encryption and division methods when storing files, it still cannot prevent file storage. The data in the area is illegally read or modified

Abstract

The invention provides a method for file invisibility processing and a system for the file invisibility processing. The method comprises the following steps: a file sent by a client terminal is received by a file processor; according to a first strategy, an encrypted file is generated and sent to a controller. The size of free storage space of a strategy execution server and the number of clusters are obtained by the controller. If the size of the free storage space of the strategy execution server is larger than or equal to the size of the encrypted file, a file allocation table is obtained and the encrypted file and the file allocation table are sent to the strategy execution server by the controller according to a second strategy. The encrypted file is stored in the clusters in the free storage space of the strategy execution server according to the received file allocation table and the received encrypted file through the strategy execution server.

Description

technical field [0001] The invention belongs to the field of instant communication, and in particular relates to a method and system for stealth processing of files. Background technique [0002] With the continuous progress of the networked society, more and more instant messaging tools are applied to work and life, such as Fetion, MSN and some enterprise application software. In practical applications, the security of file storage plays a vital role in the use of video conferencing. In the prior art, people will store files in pre-divided reserved areas. This method improves the security of file storage to a certain extent, but due to the lack of reasonable encryption and division methods when storing files, it still cannot prevent file storage. The data in the area is illegally read or modified. Contents of the invention [0003] The present invention provides a method and system for file invisible processing to solve the above problems. [0004] The invention provid...
