It is common knowledge that fingerprints and DNA are unique to individual people but a team of American researchers has now found that kneecaps too are unique to individuals and can be used to identify a particular person.
Lior Shamir of Lawrence Technological University in Southfield, Michigan, has demonstrated how a knee scan could be used to single us out.
The approach based on MRI could be used to quickly register and identify people in a moving queue as they approach passport control at airports for instance or as they walk through the entrance to an office block or other building.
Shamir has tested the approach and achieved accuracy of around 93 percent, this coupled with other factors such as possession of the correct passport, being in the right place at the right time or tied to other biometrics such as iris recognition and signature analysis could be used to prevent deception and fraud. Contact lenses can be used to dupe iris recognition systems, passports can be forged.
"Deceptive manipulation requires an invasive and complicated medical procedure, and therefore it is more resistant to spoofing compared to methods such as face, fingerprints, or iris," Shamir pointed out.
It would be almost impossible to fake one's internal body parts including the kneecaps. Of course, kneecaps are a renowned target of irreversible and deleterious adjustment in the criminal world, but even then shattered kneecaps are likely to be unique to the victim in any case.
