Definitions Edit

A biometric is "[a] physical or behavioral characteristic of a human being."[1]

A biometric is

[a] measurable, physical characteristic or personal behavioral trait used to recognize the identity, or verify the claimed identity, of an applicant.[2]
a measurable physiological or behavioral trait of a living person, especially one that can be used to identify a person or verify a claimed identity. As a biometric is uniquely bound to a person, it can provide the strongest single factor for user authentication. A biometric can be used in conjunction with a password or a token (such as a smart card) to provide strong, two-factor authentication.[3]

Biometrics pertains to the use of specific attributes that reflect unique personal characteristics, such as a fingerprint, an eye blood-vessel print, or a voice print, to validate the identity of a person.
