What other parts of human body are unique other than finger prints?

Gait

OK, it’s not quite your feet—but how you use them. Do you slightly drag one foot? Bounce on another? Even if you’ve never noticed anything unusual about how you stroll, sophisticated systems can. When an international team of bioengineers analyzed the foot pressure patterns of more than 100 participants, they identified individuals with a 99.6 percent accuracy rate. Though more research is needed, gait identification could eventually be a way of identifying individuals from a distance—such as camera footage that identifies a robber walking out of a bank.
