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 an elliptic curve and a revocable biometric certificate.

[0057] In order to enable users to securely access online services and establish secure communication between participants, the security requirements for identity verification are getting higher and higher. The portability and reliability of biometric authentication are superior to traditional technologies, and are widely used in In various online services, but facing great security risks, by adopting revocable biometrics to generate revocable pseudo-biometrics, and combining with vague promises to protect the generated pseudo-biometric templates, users and Between servers, an elliptic curve is used to establish a secure session key agreement to further improve the privacy protection of biometric authentication.

[0058] Specifically, it includes the system initialization phase, the 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 biometrics. Flow chart such as Figure 7 As shown, the system includes a client, a server, a database and a smart card, and secure communication is established between the client and the server to achieve 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 an anonymous operation on the user's identity, and uses the fuzzy commitment scheme to process the pseudo-biometric template to generate auxiliary data, which is stored 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, sends...

Abstract

The invention provides a biometric authentication method and system based on elliptic curves and cancelable biometric features, and belongs to the technical field of biometric authentication privacy protection. The invention generates pseudo-biological features by using random distance method, protects the generated pseudo-biological feature template by combining with fuzzy promise, and uses elliptic curve to establish a secure session key protocol, which further improves the security of bio-authentication privacy protection, and can resist various Therefore, it has good practical application value.

Description

technical field [0001] The invention belongs to the technical field of biometric authentication privacy protection, and in particular relates to a biometric authentication method and system based on elliptic curves and revocable biometric features. Background technique [0002] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill 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 insecure channel, they become the target of attacks, in order to protect sensitive information Not to be stolen and used illegally, the demand for identity authentication between users and servers is incre...
