Identity authentication system based on multiple biological characteristics

Abstract

The invention discloses an identity authentication system based on multiple biological characteristics. The system comprises a universal identity verification system framework which comprises a servermodule and a client module which communicate by adopting a remote procedure call protocol, wherein when a feature unit is added to a biological feature verification module, a unified implementation mode is provided for function functions of the client module and the server module of the feature unit; a biological characteristic verification module whichi comprises more than two characteristic units added according to the framework, and each characteristic unit performs identity verification through different biological characteristics; and a verification precision adjusting module used for adjusting the identity verification precision of the system, including basic precision, high precision and low precision, by setting the verification logic of the biological characteristic verificationmodule. The identity authentication precision can be flexibly adjusted as required on the premise of ensuring the accuracy and safety of identity authentication, and the flexibility of the identity authentication system when biological characteristics are increased or decreased for identity authentication is improved.

Description

technical field [0001] The invention relates to the field of identity identification, in particular to an identity verification system based on multiple biometric features. Background technique [0002] With the development of digitalization and information technology, identification has become a problem that people often encounter in daily life, especially the increasing demand for high-accuracy identification. Traditional identity authentication methods, such as identification through passwords, passwords, ID cards, etc., have shortcomings such as easy to forget, easy to crack, and inconvenient to carry, so they are facing severe tests. The biometric feature is unique information of a person, which has the characteristics of not being lost, not easy to forge, and being carried with you. Therefore, the identification technology based on biometrics has shown unprecedented superiority, and has become an international research hotspot in recent years. [0003] The so-called ...
