"Counter-terrorism experts have drawn up plans to develop an array of advanced technologies capable of spotting would-be terrorists in a crowd before they have time to strike.
Scientists and engineers have been asked to devise ways of analysing people's behaviour and physiology from afar, in the hope they may reveal clues about their mental state and even their future intentions. Under Project Hostile Intent, scientists will aim to build devices that can pick up tell-tale signs of hostile intent or deception from people's heart rates, perspiration and tiny shifts in facial expressions. The project was launched by the US department of homeland security with a call to security companies and government laboratories for assistance. According to the timetable set out, the new devices are expected to be trialled at a handful of airports, borders and ports of entry by 2012.
The project is also expected to investigate developing a lie detector-type test that can be used remotely - an advantage because it would not interfere with the flow of a crowd and it could be used without the target's knowledge."
