Embodiment Construction

[0039] The lie detection method using vibration images of the present invention will be described below in conjunction with the accompanying drawings.

[0040] Various theorists believe that all humans are born with emotions. Many researchers defined emotions from more than one angle, and by 1897, emotions were explained from three aspects, namely "pleasure and unpleasantness", "awakening and calmness", and "stress and relief". Emotions were classified in 1980 by a model developed by James Russell on a binary circular space. Such as figure 1 As shown, in Russell's model, the language of emotion is registered in a dualistic circular space of arousal and balance. figure 1 Arousal is shown on the vertical axis and mood (pleasant / unpleasant) is shown on the horizontal axis.

[0041] Vibration images revealed brain activity characterized by Vestibulo-Emotional Reflex (VER) information. That is, vibrating images measure the movement of the face and upper body, as well as subtle ...

Abstract

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 apredetermined 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 parameterextracted in the aforementioned step; and determining whether the test subject is lying by using the standard deviation.

Description

technical field [0001] The present invention relates to a method for obtaining biological signals used in the fields of biometrics, electronic engineering, medicine, etc. and a technology for detecting polygraphs using this method, specifically, using the video of the polygraph process formed in a comparative analysis to obtain physiological signals, and This is the method of judging whether it is a lie or not after analyzing it. Background technique [0002] The founder of analytical psychology, Sigmund Freud, first proposed the hypothesis of the inseparable relationship between human psychology and physiology based on scientific knowledge between 1890 and 1895. It is now widely accepted that any change in human psychology is related to physiological responses of the human body. Of course, the connection points of their mutual correlations have not yet been determined, and various methods can be used to study this. [0003] In order to obtain these comprehensive informati...
