Method for protecting digital certificate by iris recognition technology

Abstract

The invention relates to a method for protecting a digital certificate by an iris recognition technology. The method for protecting the digital certificate through the iris recognition technology comprises an iris acquisition instrument, a server, a client side and an iris recognition terminal, and comprises the following steps that a certificate issuing mechanism issues the digital certificate toa user, and iris image information is converted into binary iris information P1 through the iris acquisition instrument according to the iris image information of the user; binary exclusive-OR operation is carried out on the iris template P1 and certificate private key data to generate a ciphertext K1, and the ciphertext K1 is stored; the iris template data of the user is encrypted into a ciphertext P2 by using algorithms such as AES / SM2 and the like, and the ciphertext P2 is stored; a user uses the iris acquisition instrument to adopt the iris image information P1, the iris information is sent to a server, and the server converts the received user iris image information into binary iris information P2; and the server decrypts the locally stored user iris data to obtain an iris template P3, and the P2 is compared with the P3.

Description

technical field [0001] The invention relates to the technical field of iris recognition, in particular to a method for protecting digital certificates with iris recognition technology. Background technique [0002] Today, with the rapid development of informatization, the problems of traditional user name passwords and IC cards in protecting personal identity information and application system security are becoming more and more apparent. Problems such as password (IC card) loss, forgetting, and theft occur frequently. Digital certificates The emergence of the Internet has injected new technologies into the identity authentication of the Internet. Digital certificates are widely called "digital ID cards". Brilliant, but the use of digital certificates also has certain limitations. For example, the protection of certificates is a 6- or 8-digit digital password, which leads to low complexity in cracking digital certificates to steal personal digital identities, and theft of di...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional digital password is a weak protection scheme, which cannot be guaranteed in terms of security performance;

[0004] 2. The protection of traditional digital passwords is not conducive to the use of users and increases the difficulty of operation. Users need to carry digital certificates at any time;
