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

Embodiment Construction

[0026] The implementation of the dynamic password generation method based on iris information of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] The dynamic password, also known as the one-time password OTP, or One-Time-Password, is characterized by the fact that the user enters the dynamic password according to the displayed number of the hardware token of the service provider, and each password to log in to the server is used only once. The eavesdropped login password cannot be used for the next login. At the same time, the irreversibility of the one-way hash function such as the SHA-1 algorithm is used to prevent the eavesdropper from inferring the next login password from the eavesdropped login password. With the prevalence of e-commerce and online games, more and more attention has been paid to online identity authentication technology. People need password authentication schemes with improved reliability. Therefor...

Abstract

The invention relates to a dynamic password generating method based on iris information. The method includes that a digital camera is used for shooting the eyes of a user to acquire a digital image of the eyes of the user. An iris treatment terminal receives the digital image and extracting the iris image from the digital image, coding is conducted on the iris image based on a Gabor function set to generate binary coding data, an SM3 encryption algorithm is utilized to encrypt the binary coding data based on time factors to generate a digital format challenge code, a token device utilizes an SM3 algorithm to conduct encryption conversion on the digital format challenge code based on the time factors to acquire a dynamic password, and the user records the dynamic password into an authentication entering frame corresponding to an identity authentication server to conduct authentication. By means of the method, safety of the challenge dynamic password can be further improved, the requirements for application occasions with high reliability are met, the automation degree of the system is improved, and the use is facilitated.

Description

[0001] The present invention is a divisional application for a patent whose application number is 2014101662377, the application date is April 23, 2014, and the invention title is "Dynamic Password Generation Method Based on Iris Information". Technical field [0002] The invention relates to the field of electronic authentication, in particular to a dynamic password generation method based on iris information. Background technique [0003] 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 the mobile Internet, dynamic password technology has become the mainstream of identity authentication technology, which is widely used in enterprises, online games, finance and other fields. It is engaged in dynamic password related research and development and production at home and abroad. There are also more and more companie...
