Sensitive data protection system and method of data circulation and transaction of big data platform

Abstract

The invention discloses a sensitive data protection system of the data circulation and transaction of a big data platform. The sensitive data protection system is characterized in that the sensitive data protection system of the data circulation and transaction of the big data platform comprises a data collection module, a data sharing module, a data exchange module, a data acquisition module and a desensitization management module, wherein the data collection module discovers sensitive contents in data collection and carries out protection processing on the sensitive contents; the data sharing module carries out the protection processing on the sensitive data in a data sharing process; the data exchange module carries out desensitization processing on a relative sensitive data configuration desensitization strategy in a data exchange process; the data acquisition module protects a data file downloading link and a storage address in a data acquisition process; and the desensitization management module manages, monitors and audits the desensitization and the protection processing of the sensitive data. The invention also discloses a sensitive data protection method of the data circulation and transaction of the big data platform.

Description

technical field [0001] The invention relates to the field of big data, in particular, to a sensitive data protection system and method for data circulation and transaction of a big data platform. Background technique [0002] In the big data environment, the demand for data collection, circulation, exchange and sharing, transaction, analysis and mining is becoming stronger and stronger, and a large amount of sensitive data is collected on the big data center platform. Protecting these sensitive data in use and preventing user privacy leakage has become the focus of big data security. At present, the existing sensitive data protection adopts the following four protection methods: [0003] (1) The method of access control: by restricting the user's access to data through the user's identity and the security level to which it belongs, preventing unauthorized access to sensitive data, and realizing the protection of sensitive data. This method reduces the availability of data ...

AI Technical Summary

Problems solved by technology

[0008] (1) Most of the existing sensitive data protection methods focus on the sharing and publishing of data circulation, and lack the protection of sensitive data in the entire link of data circulation

[0009] (2) Excessive attention to user privacy will also hinder data circulation. How to combine the advantages and disadvantages of different sensitive data protection methods to select appropriate technologies for different links of data circulation and achieve a balance between sensitive data protection and data availability is an urgent problem to be solved question

[0010] (3) Most of the sensitive data protection technologies are directly processing sensitive data, but they do not consider how to discover sensitive data, how to verify the correctness and authenticity of desensitization results
