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 "signing in" and entry to premises, work on identification by nose shape is being ramped up. A lot has been done on ear shape, which also differs quite markedly from person to person. People tend to cover everything but their noses when they are up to no good.
