Biometrics

• Biometrics refers to the quantifiable data (or metrics) related to human characteristics and traits. Biometrics identification (or biometric authentication)[note 1] is used in computer science 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] Biometric identifiers are often categorized as physiological versus behavioral characteristics.
