Method and system for identification authentication using biology characteristics

Abstract

The invention provides a method for authenticating identification by biological specificity. The method comprises the following steps: firstly, a transmitting end generates a biological specificity digital certificate, wherein generation of the biological specificity digital certificate comprises the following steps: generating a public and private key pair; extracting biological specificity point information, transmitting the public key in the public and private key pair, the biological specificity point information and personal register information to a CA center, and signing and generatingthe biological specificity digital certificate by the CA center; secondly, time of two communication parties are synchronized, and during communication, a current time stamp of the transmitting end is extracted, the time stamp is loaded into the biological specificity digital certificate, and the biological specificity digital certificate is signed by the private key corresponding to the public key and is transmitted to a receiving end; and finally, the receiving end decrypts the biological specificity digital certificate by the public key, and determines whether the identification passes theauthentication or not according to the time stamp in the biological specificity digital certificate and the biological specificity point information. The invention makes identification authenticationmore secure and more reliable.

Description

technical field [0001] The invention relates to the network field, in particular to a method and system for online identity authentication using biometric technology. Background technique [0002] With the vigorous development of e-commerce and e-government on the Internet, online transactions have also developed rapidly due to its advantages of low transaction costs, convenience and speed, and online e-government has also developed rapidly due to its convenience. The number of users working has also increased dramatically. However, the security problem in the process of online transaction or data exchange is becoming increasingly prominent, and it has become a major bottleneck hindering the development of online transaction or online government affairs. This causes most users to pay more attention to the security of the whole process in addition to the convenience and speed of network transmission. In particular, when important information (such as account number and pass...

AI Technical Summary

Problems solved by technology

If the key is breached and modified, the communication content can be easily tampered with, the online identity authentication system of e-commerce and e-government affairs will be confused, and incidents such as theft of online account funds will also occur.

[0025] In addition, the private key of the digital certificate is usually fixedly stored in the computer or USB Key at the sending end, which is easy to be hacked and stolen by hackers on the Internet, which directly leads to the risk of tampering with the private key data
