Computer lie detector may undergo secrets trial at British airport
Researchers from the University of Bradford have created a computer program that detects subtle changes in facial expressions and changes in blood flow around the eyes to detect lies.
They are planning to use the program in research trials at an airport, but it is not yet clear whether passengers will know they are being monitored.

Participants were asked ten questions in which they told the truth to establish a baseline for their facial expressions and the blood flow patterns around their eyes, using a standard camera and a thermal camera. Then they were interrogated on ten questions when they had to lie.
