Dynamic password generation method based on iris information

Abstract

The invention relates to a dynamic password generation method based on iris information. The dynamic password generation method comprises the steps that a digital camera carries out shooting on the eyes of a user to obtain a digital image of the eyes of the user; an iris processing terminal receives the digital image, an iris image is extracted from the digital image, the iris image is encoded based on a Gabor function set, binary encoding data are generated, an SM3 encryption algorithm is used for encrypting the binary encoding data based on time factors, and number format challenge codes are generated; the SM3 encryption algorithm is used by a token device for carrying out encryption conversion on the number format challenge codes based on the time factors, a dynamic password is obtained, and a user inputs the dynamic password to an authentication input frame corresponding to an identity authentication server for authentication. Through the method, the safety performance of the challenge type dynamic password can be further improved, the needs of application occasions with high reliability requirements are met, meanwhile, the automation degree of the system is improved, and the system is convenient for the user to use.

Description

technical field [0001] The invention relates to the field of electronic authentication, in particular to a method for generating a dynamic password based on iris information. Background technique [0002] As one of the most secure identity authentication technologies, dynamic passwords have been applied by more and more industries. Because it is easy to use and has nothing to do with the platform, with the development of mobile Internet, dynamic password technology has become the mainstream of identity authentication technology, and is widely used in enterprises, online games, finance and other fields. It is engaged in the research and development and production of dynamic passwords at home and abroad. There are more and more enterprises. Its advantage lies in the rapid and seamless interoperability with various business systems. Its completely self-developed command dynamic password identity authentication software system is stable, efficient, and supports multiple authenti...

AI Technical Summary

Problems solved by technology

For the dynamic password in the challenge-response mode, since there is no synchronization condition between the token and the server except the same algorithm, it can effectively solve the problem of token out-of-sync, reduce the impact on the application, and greatly The reliability of the system is increased, but the disadvantage of using this dynamic password is that the user needs to manually input the challenge value when using it, which increases the complexity for the operator
