Police to Identify People by Nose Shape

Police are upgrading detective work from fingerprints to "nose prints". It seems we all have different noses, so we can be identified by surveillance cameras. While fingerprints and iris scans are being used for logins and entry to premises, work on identification by nose shape is being ramped up. A lot has been done on ear shape, which differs quite markedly from person to person.

People tend to cover everything but their noses when they are up to no good. Another thing is, if a suspect does not cooperate he/she can be identified by the shape of their nose.

Plastic surgeon Dr Peter Callan says some noses are easy in determining a person's identity. For example, there is the classic Roman nose, Greek nose, turned-up, snub and hawk nose. Cameras that film in 3D give a very accurate picture of nose shape. However, to take a picture this way a person has to be moving quite slowly. It would be okay for prisoners. For general camera surveillance only a basic shot can be taken.

It seems pinning a person down by nose shape will remain a backup system. It certainly does have its uses. Iris, face recognition and finger printing will still be the main ways of identifying a possible felon.
