Forget fingerprints. Supersleuths have found a highly successful way of tracking down terrorists, illegal immigrants, fraudsters and identity thieves: by scanning their noses.
The technology uses computer software, called the PhotoFace, to analyse the nose then put it in one of six categories.
The software measures the width of the nose tip, length of the ridge, and width of the saddle (the bit under the eyebrows).
To do this, the computer takes four photographs of a person, each one using different lighting.
This means shadows fall on different parts of the face in each photograph, which helps to determine the shape, length and depth of each part of the nose.
The system could take over from iris scanning and fingerprinting because changing the nose by plastic surgery is harder than changing the colour of the eyes
(with contact lenses) or wearing gloves to avoid leaving fingerprints.
It’s also rare to find two people with identically proportioned noses.
‘Noses are prominent facial features,’ says Dr Adrian Evans, one of the researchers involved in a study at the University of Bath. ‘They are easier to photograph and are harder to conceal, so a system that recognises noses would work better with an uncooperative subject or for covert surveillance.’
