Abstract :
The polygraphic recorder, known as lie detector, since it records physiological changes of a subject under test. Various changes in parameters such as respiration rate, EGG, blood pressure, galvanic skin response, etc are used to interpret the percentage of lying of the subject. Expert system makes it possible to analyse and display the possibility of lying of a subject reliably
