holy_calamity writes "New Scientist reports that the Dept of Homeland Security recently tested something called Future Attribute Screening Technologies (FAST) — a battery of sensors that determine whether someone is a security threat from a distance. Sensors look at facial expressions, body heat and can measure pulse and breathing rate from a distance. In trials using 140 volunteers those told to act suspicious were detected with "about 78% accuracy on mal-intent detection, and 80% on deception," says a DHS spokesman."
In seeking the unattainable, simplicity only gets in the way.
