METHOD AND DEVICE FOR PSYCHO-PHYSIOLOGICAL DETECTION (LIE DETECTION) WITH RESPECT TO DISTORTION BY USING VIDEO-BASED PHYSIOLOGICAL SIGNAL DETECTION

摘要

A method for determining whether a test subject is lying is disclosed. The disclosed method comprises the steps of: acquiring, by using a camera, a video of before and after a statement is given for a predetermined question from the test subject; extracting, from the video, at least one of parameters A1, A3, A4, A1X, A4X, INT0A, INT1A, and INT2A; calculating a standard deviation from the parameter extracted in the aforementioned step; and determining whether the test subject is lying by using the standard deviation.
