Dual confidence break-prevention method and system for files based on HOOK and window filtering

Abstract

The invention discloses a dual confidence break-prevention method and system for files based on HOOK and window filtering. The method and system are used for a management end and a client side in communication. The method includes the following steps that S1, the management end sends a HOOK and window filtering instruction to the client side; S2, the client side receives the filtering instruction,the HOOK and window filtering instruction is loaded into a system progress, and a hardware variation catching function is registered in an operation system; S3, the client side obtains equipment information interpolated into a client side computer according to the hardware variation catching function, whether equipment is storage equipment is judged, and if yes, read-write control is performed onthe USB storage equipment according to a set authority limit type of a storage equipment control strategy; S4, the client side monitors computer window information according to the window filtering instruction, and if the computer window information meets the window filtering instruction, the client side closes a corresponding computer window. In the scheme, the confidence of the files can be prevented from being broken.

Description

technical field [0001] The invention relates to the technical field of file anti-leakage, in particular to a double file anti-leakage method and system based on HOOK and window filtering. Background technique [0002] In the field of information security, document protection has always been the focus of research, especially the document transparent encryption technology, which aims to automatically complete the encryption and decryption of documents without changing the user's operating habits. Realizing a stable, efficient and secure document protection system is a difficult problem, but it has been widely used in the fields of network security and information protection. The technical difficulty is not only transparent protection, but more importantly, preventing document leakage. [0003] At present, similar computer file anti-leakage systems are mainly implemented based on the following technologies: [0004] 1. Computer file anti-leakage system based on C / S architectu...

AI Technical Summary

Problems solved by technology

[0007] 4. Many traditional anti-leakage systems for computer files prevent copying of computer files through the clipboard of the HOOK client computer. However, many copying and cutting actions of third-party software do not need to be realized through the clipboard, which directly leads to failure of such control

The original technical means can no longer satisfy the protection of these important files and key data for enterprises, especially at present, various leaking methods are constantly emerging, how to prevent computer files from leaking is more urgent
