Abstract
Biometrics refers to metrics related to human characteristics. Biometrics is a realistic authentication used as a form of identification and access control. It is also used to identify individuals in groups that are under surveillance. Biometric identifiers are then measurable, distinctive characteristics used to label and describe individuals. Biometric authenticators are frequently labeled as behavioral as well as physiological characteristics. Physiological characteristics are related to the shape of the body. By utilizing biometrics a man could be distinguished in view of "who she/he is" instead of "what she/he has" (card, token, scratch) or "what she/he knows" (secret key, PIN).In this paper, the fundamental concentrate is on the different biometrics and their applications.
