Biometrics is the science of automated recognition of persons based on one or more physiological or behavioral characteristics. Possible biometrics methods include face, fingerprint, iris, hand shape, gait, signature, etc. Biometrics is widely used in many applications, such as access control to secure facilities, verification of financial transactions, welfare fraud protection, law enforcement, and immigration status checking when entering a country. Biometrics is the only method capable of recognizing human beings using the real features of the user instead of his or her knowledge (e.g., passwords) or belongings (e.g., a magnetic stripe card). Among currently existing biometric modalities, iris recognition is considered to be one of the most secure and reliable technologies.
