A SECURITY BY BIOMETRIC AUTHENTICATION

Abstract

This paper present a state of art about biometric hand, different techniques used. Biometric is essentially used to avoid risks of password easy to find or Stoll; with as slogan save Time and Attendance. BIOMETRICS is the measurement of biological data. The term biometrics is commonly used today to refer to the authentication of a person by analyzing physical characteristics, such as fingerprints, or behavioral characteristics, such as signatures. Since many physical and behavioral characteristics are unique to an individual, biometrics provides a more reliable system of authentication than ID cards, keys, passwords, or other traditional systems. The word biometrics comes from two Greek words and means life measure. To provide a comprehensive survey, we not only categorize existing biometric techniques but also present detailed of representative methods within each category. Biometrics is a rapidly evolving technology which is being widely used in forensics such as criminal identification and prison security, and has the potential to be used in a large range of civilian application areas. Biometrics can be used to prevent unauthorized access to ATMs, cellular phones, smart cards, desktop PCs, workstations, and computer networks. It can be used during transactions conducted via telephone and internet (electronic commerce and electronic banking). In automobiles, biometrics can replace keys with key-less entry devices. Although many technologies fit in the biometric space, each works a bit differently. Relatively new on the biometric scene, face recognition devices use PC-attached cameras to record facial geometry. Once the biometric data is collected, it is encrypted and stored--locally, in the case of the desktop-only products; in a central database for the network solutions. When a user tries to log on, the software compares the incoming biometric data against the stored data.
