Information leakage prevention system

Abstract

The invention discloses a safe and reliable information anti-leakage system capable of enciphering in real time, which comprises a server and a client, wherein an operating system kernel of the client comprises an intelligent monitoring module, a dynamic enciphering and deciphering module and a log auditing module; the client enters a local safety environment after verified by the server; and the intelligent monitoring module comprises a text/binary discrimination submodule, a local file I/O monitoring submodule, a network I/O monitoring submodule, a clipboard monitoring submodule, a drag monitoring submodule and a printing monitoring submodule. The information anti-leakage system constructs a transparent use environment for users, wherein all file I/O and the all network I/O of the users in the transparent environment are automatically monitored, and all local text file I/O in the environment is automatically enciphered and deciphered. The information anti-leakage system monitors various applications and possible risks at the kernel level of the system, and has higher safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of computers, in particular to an information leakage prevention system. Background technique [0002] The ultimate goal of information security is to ensure the security of information during storage and transmission. Vulnerabilities in information security can exist in wired or wireless, fixed or mobile networks, and can also be formed through direct physical contact through USB and other device interfaces. ) technology and solutions have certain application value in the field of computer security technology. At present, some manufacturers at home and abroad have successively launched different information protection products. These products are all set for document permissions, such as read-only within a certain period of time, limit the number of prints, limit the number of read-only, etc., and there are the following security loopholes and limitations sex: [0003] 1) Only specified file formats can ...

AI Technical Summary

Problems solved by technology

[0003] 1) Only specified file formats can be processed, such as PDF, Office, TXT, CAD, etc., and some even require special readers

[0004] 2) There is no protection against the first author, the first author can arbitrarily make a copy of the important information document written by him, so it is easy to leak information through the copy of the document

[0005] 3) After the file encryption is delayed, the current information protection products can only encrypt the entire file, but before that, the file edited/modified by the author is stored in plain text o
