Semitransparent encryption method and system for preventing sensitive information leakage, terminal and medium

Abstract

The invention belongs to the technical field of information security, and discloses a semitransparent encryption method and system for preventing sensitive information leakage, a terminal and a medium, the semitransparent encryption method and system are combined with a transparent encryption strategy for use according to requirements to realize encryption by different departments according to the requirements, and the document interaction efficiency is compatible under the condition of ensuring the security of core data of a user; after a semitransparent encryption strategy is issued through the server platform, the client monitors read-write operation of an application program on a specified type of file in real time according to the strategy; an encrypted document and a common document are intelligently distinguished, and a strategy is controlled to process the encrypted document and the common document; and classifying, compressing and storing the encrypted document data and the common document data. The semitransparent encryption is used as an encryption strategy, can be independently used, and can also be combined with a transparent encryption strategy according to customer requirements, so that encryption can be carried out by different departments according to requirements, and the document interaction efficiency is compatible under the condition that the security of core data of a user is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a translucent encryption method, system, terminal and medium for preventing leakage of sensitive information. Background technique [0002] At present, with the popularity of Internet applications and people's dependence on the Internet, Internet security issues have become increasingly prominent. Malicious programs, various types of phishing and fraud continue to maintain rapid growth. At the same time, hacker attacks and large-scale personal information leakage incidents occur frequently. Accompanied by the substantial growth of various network attacks, the leakage of a large number of Internet users' personal information and property losses continue to increase. . According to public information, since 2011, 1.127 billion user privacy information has been leaked, including basic information, device information, account information, private information...

AI Technical Summary

Problems solved by technology

However, the existing encryption methods to prevent sensitive information leakage have problems in the supervision of data transmission channels, sensitive data classification, management and use of core data, and cannot meet the requirements of data security control. More powerful sensitive data security supervision and management are urgently needed. Anti-leakage protection to ensure data security in company information systems

[0004] Through the above analysis, the existing problems and defects of the existing technology are as follows: the existing encryption methods to prevent sensitive information leakage have problems in the supervision of data transmission channels, sensitive data classification, management and use of core data, and cannot meet the requirements of data security. control requirements
