Polygraph like machines to "spot terrorists" by scanning general public for anxietySteve Watson, Sept 19, 2008
The Department of Homeland Security has previewed new technology that they promise will help rout out terrorists and other dangerous people in public places by covertly bio-scanning subjects as they walk past sets of cameras.
It may seem Orwellian, but on Thursday, the Homeland Security Department showed off an early version of physiological screeners that could spot terrorists, reports USA Today.
According to DHS officials, the scanners work like polygraphs but without the subjects having to be wired up to them. They measure body temperature, pulse and breathing regularity. Any sudden changes recorded could indicate "the kind of anxiety exuded by a would-be terrorist or criminal."
According to the report, the new technology will not just be limited to use in airports:
The system would be portable and fast, said project manager Robert Burns, who envisions machines that scan people as they walk into airports, train stations or arenas. Those flagged by the machines would be interviewed in front of cameras that measure minute facial movements for signs they are lying. USA Today Article
