Identity authentication model based on block chain and face recognition

Abstract

The invention discloses an identity authentication model based on a block chain and face recognition. The identity authentication model is composed of three participants and two technical components,the three participants are respectively a user, a mobile terminal APP and a service provider, and the two technical components are respectively a face recognition neural network model and an identitychain IdentiChain based on a block chain; the user needs to become a legal authentication user of the service provider and accesses the service of the corresponding service provider through the mobileterminal APP; the user needs to complete registration operation when initiating a service request for the first time, and the service provider returns a service and a public key after registration succeeds; when the user requests the service again, verification operation needs to be completed, and after verification succeeds, the service provider returns the service and a new public key; the facerecognition neural network model receives a face image input by the mobile terminal APP, and outputs a face feature value ID of the user after training and returns the face feature value ID to the mobile terminal APP; each service provider is one of the nodes of the identity chain IdentiChain.

Description

technical field [0001] The invention relates to the fields of face recognition and block chain, in particular to an identity authentication model based on block chain and face recognition. Background technique [0002] Identity authentication refers to the process of confirming the identity of a visitor in a computer and computer network system, and then determining whether the user has access and use rights to a certain resource, ensuring the security of the system and data. It is an important means of ensuring information security. [0003] At present, the mainstream identity authentication methods are divided into the following three types: 1) to prove the identity based on the information known to the user represented by the static password; 2) to prove the identity based on the things the user owns represented by the dynamic password; 3 ) Represented by face recognition, iris recognition, etc., according to the unique biological characteristics to prove the identity of ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an identity authentication model based on blockchain and face recognition. If a node in the blockchain only has an anonymous address and cannot prove its identity, its application The scene is relatively narrow. Therefore, applying blockchain technology to identity authentication scenarios can not only solve the problems existing in traditional identity authentication methods, but also expand more application areas
