Problems solved by technology

The main process is as follows: the user defines the sensitive data pattern matching formula, determines the dictionary matching range according to the predefined model, and then uses the dictionary matching to scan the target for matching, after the scanning is completed, manually filters the matching results, and matches the pattern data Optimized, but the recognition speed will be slow due to judging criteria and dictionary matching problems

Abstract

The invention discloses a sensitive recognition method based on a knowledge graph, and the method comprises the steps: firstly carrying out the preprocessing of an obtained original data set in orderto build a user commodity knowledge graph, building a mode graph of a user-article through the preprocessed data, and then building the knowledge graph according to the preprocessed data and the modegraph; secondly, in order to identify the sensitive data, complementing the sensitive relationship which originally does not exist between the user and the object in the knowledge graph through the constructed sensitive relationship reasoning rule; and finally, inquiring sensitive data from the whole knowledge graph and outputting the sensitive data. The recognition speed is increased.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a sensitive identification method based on a knowledge map. Background technique [0002] The recommendation system is an information filtering tool, which aims to accurately predict the user's preference for the product, so as to present the product that is more valuable to the user to them first. The user's historical behavior data is the supporting basis of the recommendation system, and the user's historical behavior data often involves the user's personal sensitive data. The premise of privacy protection for sensitive data is to be able to select sensitive data from a large amount of data and complete the identification of sensitive data. [0003] Traditional sensitive data identification methods mainly include dictionary matching method and manual identification. Most of the industry uses a combination of dictionary matching methods and manual identification methods...
