According to nature.com, Homeland Security field tested the new Future Attribute Screening Technology system, at an undisclosed location in March 2011.  Up ’till now testing was done in a laboratory setting, officials claim 70% success rate.

FAST is a system that is supposed to tell if you are going to commit a crime (they call it “malintent”).  It measures things like heart rate, and eye movement.  U.S. Department of Homeland Security wants to use it at airports, sporting events, shopping malls, etc.

Many scientists question the rational of the FAST system: “Even having an iris scan or fingerprint read at immigration is enough to raise the heart rate of most legitimate travelers.”-Tom Ormerod, Investigative Expertise Unit at Lancaster University, U.K.

“I believe that the premise of this approach — that there is an identifiable physiological signature uniquely associated with malicious intent — is mistaken.”-Steven Aftergood, Federation of American Scientists
