The U.S. Transportation Security Administration (TSA) already uses human agents and surveillance cameras to search airport passengers for their bodys' non-verbal clues to predict whether they intend harm to their fellow passengers. And the U.S. Department of Homeland Security (DHS) is updating this skill using a mobile laboratory with its Future Attribute Screening Technology (FAST) program (formerly known as "Project Hostile Intent") to detect harmful intentions from its citizens.
The premise is to reconfigure large trailers to become mobile screening modules that can be set-up at major events, border crossings or even airports that consist of an array of sensors that can measure breathing patterns, pulse rates, facial expressions and skin temperatures as persons answer a series of controlled questions. These questions are akin to those asked by polygraph examiners, such as, "Are you attempting to detonate an explosive device in this airport today?"
The benefit of this approach is that unlike a polygraph examination there is no baseline questioning or wires connected to an individual, so it takes less time. It is being described by DHS and its technology partners as an, "X-ray for bad intentions". The system, known as "Malintent," uses multiple sensors - everything from cameras to infrared sensors to laser radars to collect and collate data to determine if people are displaying certain behavioral, biological or psychological markers that can be classified as malicious.
