A Study of Biometrics Technology Methods and Their Applications- A review

This paper discusses the methods of biometrics recognition technology and applications that used as personal identifying factors. Biometric recognition refers to an automatic recognition of individuals based on a feature vector(s) derived from their physiological and/or behavioral characteristic. Technologies are being developed to verify or identify individuals on the basis of measurement of face, hand geometry, iris, retina, finger, ear, voice, signature, DNA and even body order. Biometric recognition systems should provide a reliable personal recognition schemes to either confirm or determine the identity of an individual. The importance of biometrics in current fields like computer systems security, secure electronic banking, mobile phones, credit cards, secure access to buildings, Evoting, health and social services. This technology can be utilized alone or integrated with other technologies such as smart cards, encryption keys and digital signatures, biometrics is anticipated to pervade nearly all aspects of the economy and our daily lives. There are many tools and techniques that can support the management of information security. But system based on biometric has evolved to support some aspects of information security. Biometric authentication supports the facet of identification, authentication and non-repudiation in information security. Biometric systems for today’s high security applications must meet stringent performance requirements. The main reason for the acceptance of the biometrics as a tool for security is its universality, distinctiveness, permanence and collectability. Thus the biometrics methods are used as authentication technologies which offer high level accuracy for identification.
