APPARATUS AND METHOD FOR PSYCHO-PHYSIOLOGICAL DETECTION OF DECEPTION (LIE DETECTION) BY VIDEO

摘要

Disclosed is a method for determining whether or not an examinee lies. The disclosed method includes the following steps: obtaining a video before and after a statement on a certain question from an examinee by using a camera; extracting at least one parameter among A1, A3, A4, A1X, A4X, INT0A, INT1A, and INT2A from the video; calculating a standard deviation from the parameter extracted in the previous step; and determining whether or not the examinee lies by using the standard deviation.
