Problems solved by technology

However, intercepting and hiding part of the information can make the data irrelevant. For example, hiding a part of the ID number can make the ID number unable to uniquely identify a user, making it impossible or wrong to associate all aspects of user information.
Data desensitization is carried out through the set rules. Although the relevance of the data is retained, after obtaining the known desensitization data of several samples, according to the data change rules, it is possible to crack the desensitization rules, thereby restoring the data, resulting in security.

Abstract

The invention relates to a data desensitization method and device. The data desensitization method comprises the steps that similar data aggregation is carried out on original data, and to-be-desensitized data is obtained; the to-be-desensitized data is subjected to operation through an irreversible encryption algorithm, and desensitized data is obtained; if the desensitized data does not exist ina database, the desensitized data serves as a main key, and the corresponding relation between the to-be-desensitized data and the desensitized data is recorded in the database. The safety of the data is improved by using the irreversible algorithm, the correlation of the data is kept by recording the corresponding relation between the desensitized data and the to-be-desensitized data, and by means of the data desensitization method and device and under the condition that the data correlation is retained, the safety of the data is improved.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, in particular to a data desensitization method and device. Background technique [0002] Data desensitization refers to the transformation of certain sensitive information through desensitization rules to achieve reliable protection of sensitive private data. Leakage of personal information such as ID numbers, addresses, phone numbers, card numbers, and passwords may cause user accounts to be insecure and cause losses to users, requiring data desensitization. [0003] In related technologies, data desensitization can be carried out by intercepting part of the information, hiding necessary information, setting rules (such as linear transformation), and other technical means. However, intercepting and hiding part of the information can lead to data irrelevance. For example, hiding part of the ID card number can make the ID number unable to uniquely identify a user, making all aspe...
