Identity authentication system combining fingerprint identification and PKI system

Abstract

The invention relates to an identity authentication system combining fingerprint identification and a PKI system in the technical field of information security, which comprises a certificate identity authentication subsystem, a fingerprint identity authentication subsystem, a service terminal and an intelligent password fingerprint instrument, wherein the certificate identity authentication subsystem, the fingerprint identity authentication subsystem and the service terminal are connected with one another through a network, the intelligent password fingerprint instrument is directly connected with the service terminal, and the certificate identity authentication subsystem is used for network identity authentications to ensure the data secure communications between each subsystems; and the fingerprint identity authentication subsystem consists of a fingerprint verification server which stores personnel fingerprints and identity information, supports the encryption function and simultaneously can transmit fingerprint templates to the certificate identity authentication subsystem, the service terminal and the intelligent password fingerprint instrument according to requests, and can verify the fingerprint templates and return information on matching or not matching according to the requests. The security strength of the identity authentication system is strengthened greatly.

Description

technical field [0001] The invention relates to a system in the technical field of information security, in particular to an identity authentication system combining fingerprint identification and a PKI system. Background technique [0002] Information security involves the whole process of information collection, storage, transmission and access. The illegality of information operation executors and illegal destruction of information will affect information security. Various identification technologies are to establish the matching and consistency between operators and information operations. In the past, passwords and certificates were mostly used for identity verification. These methods are still widely used today. Although the establishment of this method is simple and convenient, it is accompanied by many inherent disadvantages such as easy loss, forgetting, copying and theft. [0003] Broadly speaking, all systems that provide public key encryption and digital signatu...
