Authentication method and system based on fingerprints

Abstract

The invention provides an authentication method and system based on fingerprints. The authentication method includes the steps that a server receives an authentication request, wherein the authentication request comprises identity information; the server generates challenge codes according to the authentication request and sends the challenge codes to a client side; the client side displays the challenge codes, and then a user of the client side inputs a first fingerprint sequence according to the challenge codes and a preset coding rule and sends the first fingerprint sequence to the server; the server acquires a corresponding prestored fingerprint set and a coding rule corresponding to the prestored fingerprint set according to the identity information and generates a second fingerprint sequence according to the challenge codes, the fingerprint set and the coding rule; the server matches the first fingerprint sequence with the second fingerprint sequence, and authentication is achieved when the first fingerprint sequence is matched with the second fingerprint sequence. According to the method based on the fingerprints, user authentication efficiency can be improved, the risk that the password of the user is stolen or cracked is reduced, and safety of the identity information of the user is improved.

Description

technical field [0001] The invention relates to the field of digital information transmission, in particular to a fingerprint-based authentication method and system. Background technique [0002] At present, the user name / static password authentication method is commonly used in Internet identity authentication. However, in this authentication method, the user password needs to be transmitted in the computer memory and the network, which is easily intercepted by Trojan programs or network monitoring devices. Moreover, in order to avoid forgetting the password, users often use easy-to-remember information such as birthday, phone number, etc. as the password, or use a relatively simple string as the password, which increases the possibility of the password being stolen or cracked, so there is great security. hidden danger. If a complex password is used, it will increase the difficulty for users to remember. Especially when users have multiple accounts, the burden of remember...

AI Technical Summary

Problems solved by technology

However, there are currently many ways to steal fingerprints, and people inevitably come into contact with various items in their lives, so it is difficult to implement protection measures for fingerprint information

Once the fingerprint is stolen, it may cause huge losses to the user's identity information and economic property security
