Sensitive-information desensitization method and system of transaction message

Abstract

The application provides a sensitive-information desensitization method and system of a transaction message. When the sensitive-information desensitization method of the transaction message desensitizes the transaction message containing sensitive information, a desensitization rule about the transaction message is determined according to a preset transaction message desensitization rule table storing a correspondence relationship of the sensitive information and the desensitization rule, then the transaction message is desensitized according to the determined desensitization rule to achieve the purpose of replacing the sensitive information in the transaction message on the premise of not changing data distribution characteristics and logic characteristics of the desensitized transactionmessage, and generated replacement fields are different according to different sensitive information and desensitization rules corresponding thereto. A dispersion degree of the desensitized transaction message is increased, and an effect of enabling the desensitized transaction message to satisfy a requirement of automated message playback of a comprehensive scene is facilitated.

Description

technical field [0001] The present application relates to the technical field of data processing, and more specifically, to a method and system for desensitizing sensitive information of transaction messages. Background technique [0002] With the continuous development of electronic information technology, all kinds of transactions and transaction information are stored in the form of transaction messages, especially large trading companies, e-commerce platforms and banking systems store a large number of transaction messages. These transaction messages usually record sensitive information about customers or companies, such as account, phone information, and transaction account information. Once a transaction message containing such sensitive information is leaked, it will have a bad impact on the company and the individual customer. [0003] When an enterprise builds an internal integrated application system test environment, it usually needs to perform integrated scenario...

Problems solved by technology

[0004] In the prior art, there are mainly two methods for desensitizing transaction messages containing sensitive information: 1. For a small amount of transaction messages, the sensitive information is replaced with meaningless constants; 2. For the transaction messages in the database table, According to the known database table name and the sensitive information field that needs to be replaced, the fixed field position is replaced with the preset field; among them, the processing method of the first method destroys the data distribution characteristics and logic characteristics of the original transaction message, In addition, the desensitized transaction message contains the same meaningless constant, which leads to the fact that the desensitized transaction message cannot match the basic data of the test environment, and the dispersion is low, making it difficult to meet the requirements of the desensitized transaction report. Requirements for automatic message playback in the comprehensive scenario of the document; the processing method of the second method will also make the desensitized transaction message contain the same preset fields, resulting in low dispersion of the desensitized transaction message. Difficult to meet the requirements of automated message playback in comprehensive scenarios for desensitized transaction messages
