Abstract

The embodiment of the invention provides a method and system of data masking. The method of data masking comprises the steps of reading a structuralized query language; when it is judged that the structuralized query language is in accordance with a preset masking rule, rewriting the structuralized query language according to the masking rule; executing the rewritten structuralized query language, and outputting a query result. According to the method and system of data masking, dynamic data masking can be achieved, a masked query result can be flexibly output, and the safety of the data can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a data desensitization method and a data desensitization system. Background technique [0002] With the advent of the big data era, the mining of big data business value, the precise positioning of users, and the huge business value contained in big data are gradually being tapped, but at the same time it also brings a huge challenge - the protection of personal privacy information. Personal information and personal behavior (such as location information, consumption behavior, network access behavior), etc., these are people's privacy, that is, sensitive information. How to protect the user's privacy information on the basis of big data value mining will also be the key to data detachment. A puzzle that Min must solve. [0003] Data desensitization refers to the transformation of certain sensitive information through desensitization rules, changing its value wh...
