A British team of researchers led by Professor Hassan Ugail of Bradford University have demonstrated a new type of lie-detector.

The new system records subtle clues that people give off when lying, such as increased blood flow around the eyes, tiny lip movements or nose twitching. All of these bits of information are then fed into the computer that uses an algorithm based on the work of psychologists Paul Ekman and Walter Friesen, to give an educated guess as to whether the person being analyzed is lying.
