'Covert' face-reading lie detectors to catch fugitives at airports

London , Mon, 05 Sep 2011 ANI

London, Sept 5 (ANI): Secret lie detectors, which can pick up tell-tale signs of people giving false accounts of themselves, are to be installed "covertly" at a British airport.

 

High definition video and thermal imaging cameras could be used at passport control or in customs interviews to detect those trying to trick immigration officials.

 

Scientists hope the technology will enable officials to be able to detect liars "with the click of a button" - but critics fear the devices could violate privacy if they become more widespread.

 

The system was designed by Hassan Ugail, professor of visual computing at the University of Bradford.

 

"In an interview you can be talking to a person, then you basically just press a computer button and say: "Was this person lying or not?'," the Daily Mail quoted him as telling The Sunday Times.

 

The devices work by monitoring tiny changes in facial expression, including eye movement and micro facial expressions, which indicate the increased brain activity as a liar works out the most plausible story.

 

The brain activity also triggers tiny fluctuations in facial skin temperature, which can be picked up by thermal imaging cameras.

 

The pictures are then compared with a computer database containing the types of changes seen in people who are known to be lying.

 

Those with suspect changes can then be put under deeper scrutiny.

 

Ugail is still developing the system, which has a current success rate of 60-70 per cent. (ANI)
