See the nose to detect terrorism

Fingerprints and the eye are often used to identify a person, but according to the researchers, the nose is the one that helps identify the person faster and easier.

Experts at the University of Bath in the UK say the human nose has unique characteristics, which are difficult to mimic, and they do not change much under the influence of facial expressions.

New identification technology that researchers are developing will soon play an important role in finding criminals as well as terrorists.

The facial scanning system scans the nose and analyzes in six main forms: Roman, Greek, Nubian, hawkish, upturned and nasal. Each type of nose is then examined further by computer software to analyze parts of the nose.

Nose identification makes it quicker and easier.

Dr. Adrian Evans, head of the research group, said: 'The nose is a key element of the face but so far the use of the nose for biometrics has not been fully exploited. We want to find out if they can be used to identify a person from available data. Black eye lenses are the most accurate biometric extraction unit but are difficult to capture accurately and can be blurred by the eyepiece or eyelid. However, the nose is simpler and difficult to forge. So, a nose recognition system will work better. '

Professor Melvyn Smith, from the University of the West of England, said they used three characteristics in their analysis. 'Our system works by capturing images from several corners under different lighting conditions. Then, the software works to create the color, surface orientation and depth of each point on the face by analyzing the shadows of each image. This technique can give more details than any other technology , "he said.

Researchers plan to build a nasal data bank to test and perfect software for the purpose of accurately identifying individuals in an adult group or distinguishing among the same people. lineage.
