An improved method for detecting truth or deceit ( 15 ) comprising providing a video camera ( 18 ) adapted to record images of a subject's ( 16 ) face, recording images of the subject's face, providing a mathematical model ( 62 ) of a face defined by a set of facial feature locations and textures, providing a mathematical model of facial behaviors ( 78, 82, 98, 104 ) that correlate to truth or deceit, comparing ( 64 ) the facial feature locations to the image ( 29 ) to provide a set of matched facial feature locations ( 70 ), comparing ( 77, 90, 94, 100 ) the mathematical model of facial behaviors to the matched facial feature locations, and providing a deceit indication as a function of the comparison ( 78, 91, 95, 101 or 23 ).
