Abstract

Embodiments of the invention provide a data desensitization method and device, a computer readable storage medium and electronic equipment, and relate to the technical field of big data processing. The method comprises the steps of obtaining an original structured query statement corresponding to a to-be-queried table name, and performing syntax analysis on the original structured query statementto obtain an abstract syntax tree; binding metadata corresponding to the original structured query statement with the abstract syntax tree to generate an analytic plan tree, and judging whether a to-be-desensitized field name exists in the analytic plan tree or not based on a preset matching rule; when it is determined that the to-be-desensitized field name exists, obtaining a desensitization rulecorresponding to the to-be-desensitized field name according to a preset mapping relationship; and desensitizing a value corresponding to the to-be-desensitized field name according to the desensitization rule, and executing the desensitized analytic plan tree to obtain a query result corresponding to the to-be-queried table name. According to the invention, the desensitization efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of big data processing, and more specifically, embodiments of the present invention relate to a data desensitization method, a data desensitization device, a computer-readable storage medium, and electronic equipment. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In the era of big data, faced with the huge amount of stored user privacy data, enterprises need to use big data analysis technology to realize the value of data, and at the same time avoid data leakage during the analysis process to maintain user privacy and security. Based on this, the industry has an urgent need for the desensitization technology of related big data components, and the dynamic desensitization technology is favor...
