Problems solved by technology

[0003] In the prior art, sensitive keyword detection methods or MD5 / SHA1 matching detection methods are usually used to detect sensitive files. These two methods take a long time to detect, and when keywords are tampered with, it is easy to cause detection failure, and the use effect is poor.

Abstract

The invention provides a sensitive-file detection method, a medium and equipment. According to the method, a simhash algorithm is employed to judge whether a to-be-detected file is a sensitive file {according to a comparison hash value and a to-be-detected hash value}. Compared with traditional keyword detection methods and MD5 / SHA1 matching detection methods, the method can improve speed of detecting the sensitive file, and cannot impact a detection result in a case where the to-be-detected file is relatively slightly modified. At the same time, according to the method, the simhash algorithmis employed, the to-be-detected file is judged according to the hash values without the need for reading the file, and resource occupation is lower.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a sensitive file detection method, medium and equipment. Background technique [0002] With the development of enterprise informatization, more and more information has turned to digitization, and the identification of sensitive information has also shifted from manual to automated. [0003] In the prior art, a sensitive keyword detection method or an MD5 / SHA1 matching detection method is usually used to detect sensitive files. These two methods take a long time to detect, and when keywords are tampered with, it is easy to cause detection failure, and the use effect is poor. Contents of the invention [0004] Aiming at the defects in the prior art, the present invention provides a sensitive file detection method, which can not only increase the detection speed of sensitive files, but also not affect the detection result when the file to be detected is slightly modified. ...
