The paper describes a system based on lie detection named “Lie Detection Using Facial Analysis, Electrodermal Activity, Pulse and Temperature”. Detecting lies plays a vital role in many areas, such as airport security, police investigations, counter-terrorism, etc. The system uses four parameters for detecting a lie such as facial gestures using the 68 point facial landmark, pulse and temperature sensing and electrodermal activity using the galvanic skin response i.e. GSR. The traditional method of lie detection is by using heart pulse of the convict which is not that reliable as the convict might be able to manipulate his heart pulse to avoid lie detection. The other technique to detect lies is through the identification of facial micro-expressions, which are brief, involuntary expressions shown on the face of humans when they are trying to conceal or repress emotions. Along with the pulse detection and facial analysis, the system also includes the electrodermal activity which helps to get more accuracy while testing the convict. When a set of targeted question in line with the investigation are asked to the suspect, the liars experience stress which manifests itself as body language cues. The system uses these cues to determine if the convict is telling the truth or not.
