biometrics
Identity through physiology
Biometrics is the measurement and analysis of unique physical characteristics for identification purposes.
Fingerprints, iris patterns, facial geometry, and voiceprints can verify identity more reliably than passwords or cards.
The airport uses biometrics for passport control.
The field also encompasses broader biological measurement—heart rate, gait, typing rhythm—increasingly used in security systems and personal devices.
