Biometric-based personal identity-authentication system and security analysis

1 Introduction Personal authentication system is a system that verifies a person’s identity, which he (she) claims to be, usually through login name or smart card, etc. Traditional authentication is based on the possession of a secret key, that is, once the user possesses the key, his (her) authenticity is established. Personal authentication based on PKI is one of the most prevalent authentication methods, which uses a private key to prove the user’s identity. Usually cryptographic keys a…

Biometric-based personal identity-authentication system and security analysis

The traditional authentication system is based on the secret key, and is mainly based on public key infrastructure (PKI). Unfortunately, a key has many disadvantages, for example, the key can be forgotten or stolen, and can be easily cracked. Nowadays, authentication systems using biometric technology have become more prevalent because of the advantages over password-based authentication systems. In this article, several biometric authentication models are presented, upon which most biometric authentication systems are based. Biometric authentication systems based-on these models provide high security for access control in non-face-to-face environment such as e-commerce, over open network.
