Abstract

The invention relates to an identity authentication data modeling method, device and system based on privacy protection, and the method applied to an authority end comprises the steps: building a Merkel tree model of identity authentication information, obtaining all end public keys of an identity and a root Hash value of the Merkel tree model, and obtaining the public keys of all ends of the identity and the root Hash value of the Merkel tree model; establishing a privacy information constraint according to the privacy information constraint verification logic, the identity authentication information, all identity end public keys and the privacy information constraint verification logic corresponding to the root hash value of the Merkel tree model; processing the plurality of privacy information constraints to obtain a public parameter of a proving party and a public parameter of a verifying party; and respectively performing signature calculation on each privacy information constraint, the proving party public parameter and the verifying party public parameter to generate a privacy information constraint set comprising signature items, and publishing the proving party public parameter and the verifying party public parameter as public information. Therefore, the identity authentication information has the endorsement capability of an authority, and corresponding constraint verification is carried out on different privacy data according to the requirements of application scenes.

Description

technical field [0001] The present disclosure relates to the technical field of identity authentication, and in particular to a privacy protection-based identity authentication data modeling method, device and system. Background technique [0002] The current identity authentication method leaks too much private information, so the current application system proposes different zero-knowledge proof methods to protect the security of private data in identity authentication. [0003] In the current relevant identity authentication technology, there are the following technical problems: [0004] 1. The certification information does not have the endorsement ability of an authoritative organization [0005] 2. The authentication method does not have the ability to protect private data [0006] 3. The authentication method does not have the expansion capability of private data constraint verification Contents of the invention [0007] In order to solve the above technical pro...
