Problems solved by technology

[0005] In order to establish a secure channel on the open network, further improve the privacy protection of reversible biometric technology, and better verify the authenticity of servers and users, mutual authentication and session keys play an important role. The current key agreement The scheme cannot resist denial of service attacks, cannot provide perfect forward secrecy, cannot resist user anonymity and impersonation attacks and replay attacks, etc., to develop a reliable new biometric authentication key agreement scheme, which can overcome the existing well-known attacks is a new challenge

Embodiment 1

[0056] Embodiment 1 of the present invention provides a biometric authentication method for privacy protection based on elliptic curves and revocable biometric certificates.

[0057] In order to enable users to safely access online services and establish secure communications between participants, the security requirements for identity verification are getting higher and higher. Among them, the portability and reliability of biometric authentication are superior to traditional technologies, and are widely used in Various online services face great security risks. By using revocable biometrics to generate revocable pseudo-biometrics and combining them with fuzzy commitments to protect the generated pseudo-biometrics templates, users and Between servers, the elliptic curve is used to establish a secure session key agreement to further improve the privacy protection of biometric authentication.

[0058] It specifically includes the system initialization phase, registration phase,...

Embodiment 2

[0079] In one or more embodiments, the present invention provides a system for privacy-preserving biometric authentication based on elliptic curves and revocable biometric features. Flowchart such as Figure 7 As shown, the system includes client, server, database and smart card, establishes secure communication between client and server, and realizes the following functions.

[0080] (1) Registration stage

[0081] The client sends the user's identity to the server, and stores the converted pseudo-biometric template in the database. The server performs anonymous operations on the user's identity, uses the fuzzy commitment scheme to process the pseudo-biometric template to generate auxiliary data, and stores it in the database. middle.

[0082] (2) Verification stage

[0083] The client user carries the smart card to enter the identity, password and biometric information, uses the same conversion parameters to generate a pseudo-biometric template, and sends it and the anony...

Abstract

The invention provides a biometric authentication method and system based on an elliptic curve and capable of cancelling biological characteristics, and belongs to the technical field of biometric authentication privacy protection. Pseudo-biological characteristics are generated by using a random distance method, the generated pseudo-biological characteristic template is protected by combining thepseudo-biological characteristics with fuzzy commitments, and a secure session key protocol is established by using an elliptic curve, so that the security of biometric authentication privacy protection is further improved, and various attacks can be resisted, and therefore, the invention has a good practical application value.

Description

technical field [0001] The invention belongs to the technical field of biometric authentication privacy protection, in particular to a biometric authentication method and system based on elliptic curves and cancelable biometric features. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] With the rapid development of the Internet and mobile technology, various convenient online services are provided for our lives, but when users access these services through an unsafe channel, they become the target of attacks, in order to protect sensitive information Not to be stolen and illegally used, the demand for identity authentication between users and servers is getting higher and ...
