Abstract

The invention discloses a method and a system for preventing sensitive data leakage. The method comprises the following steps: establishing an original sensitive field library by utilizing a preset sensitive field discovery algorithm; obtaining metadata in the whole life cycle process of the sensitive data; according to the original sensitive field library and the metadata, analyzing a model and acode in a sensitive data circulation process, and obtaining a blood relationship and a use path of sensitive data in a full link; obtaining a sensitive data use list by utilizing the blood relationship and the use path of the sensitive data; analyzing the sensitive data conversion process by using a preset data feature analysis algorithm to obtain a sensitive data check list; performing early warning and auditing sensitive data. According to the method, the original sensitive field library, metadata management, model and code analysis, sensitive data blood relationship, sensitive data contentfeature analysis and early warning audit are combined, so that the transfer and use process of the sensitive data is more intuitive and clearer, and the risk of sensitive data leakage in each link inthe full life cycle of the data is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of data security governance, in particular to a method and system for preventing sensitive data leakage. Background technique [0002] The power grid field has a large amount of sensitive data such as marketing data, scheduling data, and personal electricity consumption information data. Due to the scattered sources, large scale, rapid growth, various types, different structures, and irregular descriptions of the data, the granularity of sensitive data is inconsistent. First, the span of time and space is large, so there is a risk of sensitive data leakage in all links of data transmission, storage, processing, analysis and mining. [0003] At present, the methods for protecting sensitive data are mostly sensitive data discovery method, sensitive data classification and classification, sensitive data access control, etc. Tracking problems, dealing with the conversion or reverse conversion of non-sensitive r...
