The biological data used in detection of biomethics system is more likely to be ignored. • Physiological: Human face, hand finger, hand line, retina, iris, vein. Behavioral: The behavior of the person, handwriting, talking or moving style. . These are described below: Face: Assess the characteristics of the face and give it protection. Due to differences in ala in this technology The complexity of the case occurs. Besides hairstyles, beard changes, makeup use, jewelery use Disrupts face recognition. Hand Finger: Currently comparisons of office, court, employee identification to different autonomous organizations. The most widely used method is Fingerprint Reader. One by using this method. The fingerprint image of the person's hand is taken through the scans. Then processing it on the computer. Is stored on the database. Later on, under the reader, the fingerprints below the fingers are digital. The person is identified by converting and matching the matching points. In biometric procedures. Finger prints worldwide have the highest popularity. Advantages: • The price of the device used in finger print method is low. • Using this method is cost-less and success rate is almost 100%. • Recognition takes very little time. Disadvantages: • Who works for the workers. This system works particularly well for the people of the country, especially for the elephants. Due to the hammer patta the finger print may be broken. | The correct person can not be identified if dryness, finger dirt or corner type lining is involved. .. Scientific technology to measure and analyze biological data in biometrics. The Greek word "bio" (which means life) and metric "(which means measurements) have been derived from biometrics. Biometrics is a kind of type. Strategy or technology by which people are defined by physical structures, behaviors, attributes, qualities, personality etc. The person can be identified or identified. The basic work of biometrics is to find out the unique characteristics of each and every person, Helping to identify different aspects of the feature. Biometric methods are used to ensure computer safety. In this method, human biological data is stored on the computer's database and subsequently these data is automatically matched. If you match the data, it is considered valid and is allowed. Various organizations maintain access control for various types of access to their offices - (Access is restricted to one office by one type of machine, access to the office, at the corner, in the office, at the corner of the office, the fingerprint printed in the office at the proximated identity card, All the Movements, including their presence, save on the database Sometimes we face as a child computer system passwords, pupils, finger prints, etc., and do. In fact, all the bayaemetriksa system.
