Information compounding desensitization method based on association of sensitive information types

Abstract

The invention relates to an information compounding desensitization method based on association of sensitive information types. The method comprises the following steps that database field informationto be desensitized is determined; the sensitive information types contained in the database field information are set; desensitization rules corresponding to the sensitive information types one to one are set; all information values of the database field information are subjected to sensitive information type matching; desensitization is conducted according to the desensitization rules corresponding to the sensitive information types, and the desensitization information values are updated to a database. According to the information compounding desensitization method, all the information values in the database field information can be matched with the set sensitive information types, all the information values in the database field information are converted according to the desensitizationrules corresponding to the sensitive information types, multiple kinds of sensitive information types can be identified and matched at the same time, multiple pieces of sensitive information can be desensitized at the same time, and the safety of personal information is improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an information composite desensitization method based on sensitive information type association. Background technique [0002] At present, while big data is widely used, the protection of personal information is facing unprecedented challenges. While enjoying the appropriate services brought by data analysis to their lives, people are also troubled by personal information leakage or even being harassed. Therefore, it is particularly important to desensitize the use of data. [0003] Data desensitization refers to the transformation of certain sensitive information through desensitization rules to achieve reliable protection of sensitive private data. This way, masked real-world datasets can be safely used in development, testing, and other non-production environments, as well as in outsourced or cloud computing environments. [0004] The desensitization function in...

Problems solved by technology

[0004] The desensitization function in the existing technology only desensitizes a single type of sensitive data of the user, for example: desensitize the phone number data to the phone number, desensitize the name data to the name, desensitize the ID number data to the ID number ; The common desensitization method is insufficient for the desensitization of composite data information. For example, when the original data also has composite data information such as phone number, name, and ID card number, the normal desensitization method cannot correspond to the original information type of the user. desensitization of data
