High-security desensitization method based on big data information system

Abstract

The invention relates to a high-security desensitization method based on a big data information system. The method is characterized by comprising the first step of conducting preprocessing before conducting desensitization use on sensitive data; the second steps of using a compound layering type desensitization algorithm model to conduct encryption on the sensitive data; the third step of conducting source tracing and auditing after conducting desensitization use on the sensitive data. According to the high-security desensitization method based on the big data information system, the compound layering type desensitization algorithm is adopted as a core, and the method is used for realizing protection of the visited sensitive information under the situation that an information system is invaded illegally and authority is utilized to break loopholes of a traditional desensitization algorithm. The high-security desensitization method based on the big data information system has the advantages that on the one hand, the danger coefficient of the sensitive data is effectively reduced, the security of the sensitive data is sharply improved, the breaking difficulty coefficient is sharply increased, and desensitization protection of the sensitive data is realized; on the other hand, efficiency characteristics of each arithmetic unit in the desensitization model can be given full play through the model algorithm.

Description

technical field [0001] The invention relates to a high-security desensitization method based on a big data information system. Background technique [0002] At present, with the continuous deepening of my country's informatization construction, the enterprise's informatization business system is increasingly dependent on the information communication system, and the security and reliability of the information communication system will directly affect the security and confidentiality of enterprise data information; however, data resources Often contains a large amount of sensitive information, once leaked or illegally used, it will bring irreparable losses to individuals and even the country. [0003] The database protects data security through user, role, and permission technologies. However, most applications do not make full use of this protection mechanism of the database, but control data access through applications. For example, application operators log in to the databa...

Problems solved by technology

Among them, the data volume of sensitive information is also growing rapidly, reaching the PB level. When traditional desensitization technologies face such a large amount of sensitive data, it is difficult to effectively process and solve the problem of sensitive data desensitization.
