Modern life spreads worldwide (estimate 500 million people) connected with the technology revolution or Cyber Generation which transformed the way of living. As with, powerful developments of technology boost.

The technology covers the development of IT security. It have been said about the bloom of security code, where you can protect your personal data. For most people it sounds cool. It’s like an idea called from James Bond on the movie Mission Impossible so it end up getting just to be at the cutting edge.

However, unlike in the movies, people can seem to find use for it yet, at least in the practical sense. One of the technologies that boost is the BIOMETRICS. Biometric authentication technologies have been use in the personal physical characteristics or behavior to physical access control systems for many years.

Biometrics starts with fingerprinting; the first recorded use of finger prints was by ancient Assyrians and Chinese for the signing of legal documents. Probably, the first modern study of fingerprints was made by the Czech physiologist Johannes Evangelista Purkinje (1823), who proposed a system of classification that attracted little attention. The use of fingerprints for identification purposes was proposed late in the 19^th century by the British Scientist Sir Francis Galton, who wrote a detailed study of fingerprints in which he presented a new classification system using prints of all ten fingers, which are the basics of identification systems still in use. Until it reach the modernity, it becomes biometric. (http://en.wikipedia.org/wiki/Biometrics)

Biometrics comes from the greek hybrid words of bio meaning life and metry meaning to measure. The websters biological observations & phenomena. In a more simplier terms biometrics means using the body as a password. Biometric identification is simply the technique of verifying a person by a physical characteristics or personal trait.

There are two main classes of Biometric characteristic. First, physiological which are related to the shape of the body. The oldest traits are the fingerprints, other examples are face recognition, iris recognition. Second, behavioral which are related to the behavior of a person. The first characteristic to be used still widely used is the signature. More modern approaches are the study of keystroke, dynamic, vein recognition and voice. Strictly speaking, voice is also a physiological trait because every person has a different pitch of voice recognition is mainly based on the study of the way a person speaks, commonly classified as behavioral. Other biometric strategies are being developed such as those based on gait(way of walking), retina, hard veins, ear canal, facial thermogram, DNA, odor and scent and palm prints.

There are many biometrics that have been used today and the future holds more advances. Like at Coca Cola Company, land scanning machine recently replaced and venerable time card for many workers. Fingerprint scanners crack down on people claiming welfare benefits. In other schools, they are installing automated teller machines with a finger scanner that will identify their personal identification numbers. Mastercard International Inc., and Visa USA Inc. the world largest credit card companies, begun to study the feasibility of using a finger-scanning devices at the card holder. The scanners would compare fingerprints with biometric Information stored on a microchip embedded in the credit card.

As an important mechanism for verification & identification, Biometrics system result to be rampant or spread worldwide. Verification which authenticates its users in conjunction by a smart card, username or ID number. The biometric template captured is compared with that stoned against the registered user either on a smart card on database for verification. Identification which will authenticates its users from the biometric characteristic alone without the biometric template is compared to all records within the database & a closest. With the used of biometrics, there will be a central database to contain the digital templates from everyone eyes, fingers or voices. This technologies starting to bloom. And your right as an individual or person will be protected, your privacy about yourself and direction through the use of an important mechanism for verification & identification which is BIOMETRICS.
