An undisclosed airport in Britain is implementing this new technology that keeps an unwitting eye on people entering the country by scanning passengers for signs of truthfulness.
Mail Online News has reported on Britain’s new security defense. This covert operation, if you will, could be used at passport control stations and in customs interview rooms. The “new” deception detection tool has a greater advantage than the current tools such as electronic body scanners and metal detectors because it is being implemented without the knowledge of the person in question.
This device reads tiny changes in facial expressions such as eye movement and micro facial expressions that have corresponding reactions in the brain, which cause changes in the patterns of blood flow around the face. The changes in blood flow to the face are picked up by thermal imaging cameras. These “truthfulness” measurements can prove to be useful not only in airports but in a variety of places such as schools and business conferences.
The system’s designer Hassan Ugail, a professor of visual computing at the University of Bradford, commented on this software, ‘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?”’
Detecting deception with just a click of the button can be misleading. What do you think about this type of software? Do “real” people also need to be trained to understand the nuances of human behavior for this to be a double edged sword for criminals?
Professor Ugail goes on to state, “What we try to do is experiment with the face itself, but it is purely non-invasive, which means the person is probably not aware the measurements are being taken.”
This system is still being developed but Ugail and his colleagues have claimed a 60-70 percent success rate.
What are your thoughts on this non-invasive lie detection technology?
