Biometric Authentication System by Various Techniques

Abstract

Biometrics is an evolving technology which is used in various fields like forensics, secured area and security system. Biometric system takes the base for the pattern recognition system that recognize a person with authentication by using different features such as Fingerprint, Retinal Scan, Iris scan, Hand geometry and Face recognition. These are the major biometrics systems. These are used in various applications like ATM, cellular phones, secure access to a building. Biometrics are designed to enhance the security and reduce vulnerability. In this paper different biometrics techniques such as Fingerprint, Iris Scan, Retinal Scan, Face Recognition, Hand Geometry, Voice and Signature are available to implement a biometric system.
