Technologies that employ a distinctive, measurable biological or behavioral characteristic that can reliably distinguish one individual from another (biometric) for authentication, identification, and verification of individuals. Biometric authentication is the process of confirming the identity of an individual by comparing the individual's biometric sample against (1) one or more previously collected reference samples (biometric identification) or (2) a specific reference sample based on the individual's claimed identity (biometric verification). Biometric identification is a one-to-many process, and biometric verification is a one-to-one process. Biometric technologies commonly used for authentication and identification in access control systems include fingerprints, iris, voice, and face recognition (see illustration).
