INTRODUCTION: Todays society is largely affected by false hood. Criminals have been good at telling lies so efficiently that apparently it becomes difficult for the interrogators to find out what is hidden underneath. Although not fully yet polygraph or lie detector has provided assistance to address this problem up to some extent.A polygraph (popularly referred to as a lie detector) is an instrument that measures and records several physiological responses such as blood pressure, pulse, respiration rhythms body temperature and skin conductivity while the subject is asked and answers a series of questions, on the theory that false answers will produce distinctive measurements. The polygraph measures physiological changes caused by the sympathetic nervous system
