Biometrics refers to the identification of humans by their characteristics or traits. Biometrics is used in computer science as a form of identification and access control.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. Biometric identifiers are often categorized as physiological versus behavioral characteristics. 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.

Other than facial, voice, fingerprints, signature, iris (eye), vein uniqueness, Can we also consider footprints unique from person to person as Biometric identifiers ?

Similar to Thumb impression, the Foot Thumb impression will vary from person to person ?.

Awaiting your reply,

Thanks & Regards,

Answer
Footprints are often taken of babies to identify them. They are not generally useful in criminal identification, because most people wear shoes, and don't leave footprints. As means of routine identification, for access entry, etc. they would be inconvenient, as one would need to remove one's shoes.
With other unique biometric identifiers that do not require removal of clothing, foot-prints or toe prints will not likely gain acceptance as a means of identification for access control devices.

If you have a laptop, with a fingerprint password device, you could certainly use a toe instead of a finger, but I expect you'd soon find it inconvenient to remove your shoe and sock every time you wished to use your PC.
