Tech Fragments reports on Homeland Security's Future Attribute Screening Technology (FAST), which will screen people for "mal-intent" as they walk past checkpoints.
The system uses cameras to detect slight alterations in pupil sizes, blink rate and even direction of gaze. A laser radar called BioLIDAR measures heart rate and changes between heartbeats. The BioLIDAR can even monitor a persons respiration and track movements in the face, neck, and cheeks. Stressed out? A thermal camera will pick up on this too by gauging changes in the skin temperature.Homeland Security ran a test in September of 140 volunteers using a FAST prototype. The system was very accurately able to pick out people with hostile intent. "We're still very early on in this research, but it is looking very promising," says DHS science spokesman John Verrico. "We are running at about 78% accuracy on mal-intent detection, and 80% on deception."
