英国巴斯大学的科学家最新研究发现，在特定扫描技术的帮助下，安全人员可以通过人的鼻型辨识出非法移民、恐怖分子或者犯罪分子，而且因为鼻子不容易隐藏，因此其辨识的可信度比指纹或虹膜的扫描识别度要高。

New technology designed to read the unique shapes of each nose could be used to identify Illegal immigrants, terrorists and criminals, experts claim.

Scientists have discovered an unlikely new weapon in the fight against international terrorism – the human nose.

New technology designed to read the unique shapes of each nose could be used to identify Illegal immigrants, terrorists and criminals, experts claim.

The nose is more reliable（可靠的，可信赖的） than fingerprints² or irises⁴（虹膜） as a means of identification because it is harder to conceal⁵, they say.

A new scanner, known as the PhotoFace, takes four flash-lit photographs lit in rapid succession from several different angles.

The nasal images are then analyzed⁷ according to six main shapes – Roman, Greek, Nubian, Hawk⁸, Snub and Turn-up.

Each nose is then further tested by computer software to analyze⁶ its profile, the tip, and the nasion（鼻根） – the top of the nose where it meets the eye line.

Dr Adrian Evans, who conducted the research behind the technology at the University of Bath, said scanning noses could be an easier way to verify an identity than iris³ and fingerprint¹ scans.

''There's no one magic biometric（计量生物学） – irises are a powerful biometric, but can be difficult to capture accurately⁹ and can easily be obscured（掩盖，遮蔽） by eyelids¹⁰ or glasses,” he said.

''Noses, however, are much easier to photograph and are harder to conceal, so a system that recognizes noses would work better with an uncooperative subject or for covert¹¹（隐蔽的） surveillance.''
