Abstract

In order to realize data desensitization for safely and effectively shielding security transaction trend information, the inventor provides a data desensitization method. The method comprises the following steps: acquiring data to be desensitized; establishing first trend data and second trend data according to the data to be desensitized; acquiring a user password, and acquiring a dynamic key according to the user password and a preset dynamic key scheme; performing change processing on the first trend data according to the user password and the dynamic key to obtain new first trend data; establishing new second trend data through the new first trend data, and performing change processing on the second trend data according to the new second trend data, a user password and a dynamic key. According to the scheme, the high-value information of the security transaction flow trend is finally shielded and masked by dividing the data units and disturbing the two-stage data units, so that the security of the data in multiple scenes such as sharing, transmission and test environments is ensured, and leakage is avoided.

Description

technical field [0001] The invention relates to the field of computer software, in particular to a desensitization method and device for sensitive data in the securities industry. Background technique [0002] With the rapid development of information technology, enterprise business systems have accumulated a large amount of personal privacy data and high-value enterprise information after years of precipitation. In addition to internal circulation, massive data also needs to be "shared" externally, which is also the demand and premise of the national big data development strategic plan. How to ensure the security and availability of data in scenarios such as generation, exchange, sharing, development and testing has become a key issue that customers urgently need to solve. Data desensitization has also become one of the important means to solve the above problems. [0003] As the name suggests, data desensitization is to deform sensitive data, and its purpose is to protec...
