Embodiment Construction

[0014] Various exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. The flowchart and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of methods and systems according to various embodiments of the present disclosure. It should be noted that each block in a flowchart or a block diagram may represent a module, a program segment, or a part of a code, and the module, a program segment, or a part of a code may include one or more An executable instruction for a specified logical function. It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or they may sometimes be executed in the reverse order, depending upon the functionality involved. It should also b...

Abstract

The embodiment of the invention relates to a data desensitization method and system. The method includes the steps that an identifier corresponding to original data is generated at a service module; the original data and the identifier are sent from the service module to a data encryption module; desensitization data is received from the data encryption module at the service module, wherein the desensitization data is generated after the data encryption module encrypts the original data through a secret key, and the secret key is generate based on the identifier; the desensitization data and the identifier are sent from the service module to a data storage module, and the service module, the data encryption module and the data storage module are located in the same local area network and are physically separated. According to the embodiment, the encryption secret key and the encrypted desensitization data are physically separated and stored in the local area network environment, strict access permission is set for the encryption secret key and the desensitization data, and therefore the safety of data encryption or decryption can be effectively guaranteed.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of data encryption and decryption, and more specifically relate to a data desensitization method and system. Background technique [0002] Data desensitization refers to the transformation of certain sensitive information through desensitization rules to achieve reliable protection of sensitive private data. The common way of data desensitization is to encrypt data. With the help of data masking technology, sensitive information is shielded, and the masked information retains its original data format and attributes, so as to ensure that the system or application can run normally during the development and testing process using masked data. [0003] Due to industry regulatory requirements and the need to protect user privacy information, private information in some systems or applications must be desensitized before being stored in system logs. Moreover, when the system needs to call t...
