Proving material privacy data processing method based on block chain

Abstract

The invention provides a block chain-based certificate material privacy data processing method, which comprises the following steps: 1) an electronic certificate material storage step: a user submits an electronic certificate material to a trusted data platform, and the trusted data platform performs noise addition processing on the electronic certificate material to form desensitized data, and then the trusted data platform respectively calculates hash values of the original electronic certificate material and the desensitization data, and the block chain returns a corresponding material number to the event processing platform; 2) an electronic certificate material verification step: a user sends an electronic certificate material and a material number to a verification platform; and 3) a desensitization data lookup and verification step: the event management mechanism obtains the material number of the event proof material and the desensitization data from the database, and sends the material number and the desensitization data to a verification platform. In this way, the block chain technology can ensure that data is not tampered, differential privacy protects data privacy, data stored in a database is prevented from being attacked and leaked, and meanwhile, collection of effective electronic certificate materials is ensured during event processing.

Description

technical field [0001] The present invention relates to block chain technology, in particular to block chain-based privacy data processing technology. Background technique [0002] With the rapid advancement of informatization, a large number of proof materials in event processing are presented in the form of electronic data materials, and the forms of electronic data are increasingly diversified, and the frequency of use and data volume of electronic proof materials have increased significantly. Compared with traditional certification materials, electronic certification materials have the characteristics of perishability, easy tampering, and strong technical dependence, and the authenticity and legality of electronic certification materials are more difficult to review and authenticate. Moreover, electronic certification materials often involve sensitive information such as personal privacy and business secrets. If these private data are directly stored in the network, once...

Compared with traditional certification materials, electronic certification materials have the characteristics of perishability, easy tampering, and strong technical dependence, and it is more difficult to verify the authenticity and legality of electronic certification materials

Moreover, electronic certification materials often involve sensitive information such as personal privacy and business secrets. If these private data are directly stored in the network, once they are attacked and leaked, it will cause huge losses to the interests of the parties involved, and will also have a negative impact on the event management agency.
