ABSTRACT
Biometrics is a generic term that refers to a wide range of measures of biological data. The use of biometrics is not new. The signature has been used for authentication for a very long time. Later the system was fine tuned to a photograph. A whole range of well-known and new biometrics is being used and experimented with.
Biometrics is the process of identifying an individual using his physical feature(s) or action(s) which are both unique and measurable. Real life applications like ATM, AIRPORTS, and BANKS etc lack proper security as the logical elements of security like passwords, ID cards are easily captured. The ambiguity in using them can be relieved using various biometric technologies.
Latest advances in the field of biometrics can be categorized into technologies like face recognition, finger scanning, retina patterns, hand geometry,
Voice recognition etc. Combination of these technologies with the logical identities ensures a remarkable security to the applications.
Understanding the technologies not only ensures proper utility but also provides an initiative for future advances. Our paper is a description of the face recognition technology. Biometric face recognition is currently used in handful of applications to guard against the perceived threat of hackers. A number of groups are looking at using this technology in the near future.
