A polygraph, popularly referred to as a lie detector (test), is a device or procedure that measures and records several physiological indicators such as blood pressure, pulse, respiration, and skin conductivity while a person is asked and answers a series of questions the belief underpinning the use of the polygraph is that deceptive answers will produce physiological responses that can be. Face reading technology for lie detection by hugail, mhyap, brajoub technology for lie/guilt detection •system should be purely based on reading cues from the face (nothing else) potential to outperform traditional polygraph measures.

Qualitatively changed crimeusing conventional, traditional techniques consequently there is the needfor newdetectionmethods, meaningful information meaningful is there any evidence that the polygraph is really able to detect lies the machine measures changes in blood pressure, pulse, and respiration rate when a person lies it is assumed. A technology that monitors miniscule shifts in the heat of the human face as a means of detecting deception laser doppler vibrometry a lie detection technique that monitors physiological stress like respiration, heart rate, muscle tremors via a near-infrared light beam aimed at the neck of a subject a few 100 feet away. Source of evidence the evidence for polygraph validity lies primarily in atheoretical, empirical studies showing associations between summary scores derived from polygraph measures and independent indicators of truth or deception, in short, in studies that estimate the accuracy of polygraph tests.
