In looking for the next big possibility in biometric identifiers, a computer scientist believes the knees might have it.

As reported on Science Daily, Lior Shamir, a computer scientists at Lawrence Technological University in Southfield, Michigan, says knees are just as unique as fingerprints and could be a valid identifier.

Shamir says that biometric knee scans can be based on MRI, and they could be used to detect people as they are moving, for example, into a building or in a line at passport control.

Shamir’s tests have come back with approximately a 93% accuracy rate. While knees can be manipulated and changed, Shamir says that takes a great deal of effort, so it’s much easier to rely on its constant uniqueness.

Shamir believes that knee scans along with another identifier could prove to be a good multi-modal identification system.
