A big data environment-oriented privacy information leakage prevention automatic identification method and system

Abstract

The invention relates to a big data environment-oriented privacy information leakage prevention automatic identification method and system, and the method comprises the steps of screening keywords, and judging that the keywords are automatically extracted; according to the extracted keywords, filtering out the content of the positive privacy-free information, and providing the input for a privacyinformation judgment module; and carrying out deep content analysis on the preliminarily screened data, judging the privacy information, and giving out a judgment result. The method is simple to implement, the judgment data size of the privacy information judgment module is reduced to a great extent aiming at the condition that the output port for data collection or data circulation faces mass data, and the judgment accuracy of privacy information is improved; the automatic extraction of text keywords and deep analysis of privacy information are realized, and the judgment accuracy is high; thetimely updating of the keyword list and the classifier is achieved, and the recall rate and the judgment accuracy of privacy information screening are further improved.

Description

technical field [0001] The invention relates to an automatic identification method and system for anti-disclosure of privacy information in a big data environment.
