Biometrics (or biometric authentication)[note 1] refers to the identification of humans by their characteristics or traits. Computer science, biometrics to be specific, is used as a form of identification and access control.[1] It is also used to identify individuals in groups that are under surveillance.
Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals.[2] The two categories of biometric identifiers include physiological and behavioral characteristics.[3] A physiological biometric would identify by one's voice, DNA, hand print or behavior. Behavioral biometrics are related to the behavior of a person, including but not limited to: typing rhythm, gait, and voice.[note 2] Some researchers have coined the termbehaviometrics to describe the latter class of biometrics.[4]
More traditional means of access control include token-based identification systems, such as a driver's license orpassport, and knowledge-based identification systems, such as a password or personal identification number.[2] Since biometric identifiers are unique to individuals, they are more reliable in verifying identity than token and knowledge-based methods, however, the collection of biometric identifiers raises privacy concerns about the ultimate use of this information.[2][5]
