Download PDF

Abstract:
The lie detector known as Polygraphic Recorder, since it records physiological changes of a subject under test. Various changes in parameters such as respiration rate, blood pressure (B.P) are used to interpret the percentage of lying by the subject. It is possible to analyze and display the possibility of lying by a subject reliably using expert system. The purpose of this study is to investigate the physiological responses while the subject is lying. When we lie, our blood pressure goes up, our heart beats faster, we breathe more quickly (and our breathing slows once the lie has been told). This work evaluating, examining, calculating and observing, an examiner can tell from those scribbles whether or not you have spoken the truth
