In this paper, robust authentication mechanism using user’s biometrics signals for complementing traditional authentication’s weak points is proposed. In the absence of robust personal recognition schemes, these systems are vulnerable to the wiles of an impostor. Nowadays, authentication system are developed using biometric. Biometric recognition, or simply biometrics, refers to the automatic recognition of individuals based on their physiological and/or behavioral characteristics. The different types of biometric used in authentication system are iris, fingerprint, vein pattern, hand geometry etc. A biometric system provides an automated method of identifying a human being based on his/her biometric characteristics. But there are some security problems. Some biometrics can be copied by a malicious user with scanners. All biometrics characteristics extracted from a user are not possible to maintain a steady normal condition. A biometrics signal is a pattern recognition that uniquely identifies human being based on his/her physiological traits. A biometrics signals should be impossible to masquerade or manipulate. This attribute is used as 3rd authentication phase. Proposed authentication mechanism is composed of 3 layered authentications; ID&P/W, PIN number or biometrics, and biometrics signals.
