In Information Technology (IT), biometric authentication refers to technologies for measuring and analyzing human physical and behavioral characteristics for authentication purposes. Examples of mostly physical characteristics include fingerprints, eye retinas and irises, facial patterns and hand measurements, while examples of mostly behavioural characteristics include signature, gait and typing patterns. Voice is considered a mix of both physical and behavioral characteristics, but all biometric traits share physical and behavioral aspects.
