Contrary to a traditional polygraph (also known as a lie detector) that relies on changes to sweat glands as nervous responses to determine the subject's honesty, brain fingerprinting is entirely concealed in the brain's responses to stimuli. [7] This makes the technique harder to resist or beat, making it a more reliable method of detecting lies.
Lie detection is an assessment of a verbal statement with the goal to reveal a possible intentional deceit. Lie detection may refer to a cognitive process of detecting deception by evaluating message content as well as non-verbal cues. [ 1 ]
American inventor Leonarde Keeler testing his improved polygraph on Arthur Koehler, a former witness for the prosecution at the 1935 trial of Richard Hauptmann. A polygraph, often incorrectly referred to as a lie detector test, [1] [2] [3] is a pseudoscientific [4] [5] [6] device or procedure that measures and records several physiological indicators such as blood pressure, pulse, respiration ...
The Silent Talker Lie Detector is an attempt to increase the accuracy of the most common lie detector, the polygraph, which does not directly measure whether the subject is truthful, but records physiological measures that are associated with emotional responses.

The use of voice stress analysis (VSA) for the detection of deception is controversial. Discussions about the application of VSA have focused on whether this technology can indeed reliably detect stress, and, if so, whether deception can be inferred from this stress. [2]
As "Prospects of fMRI as a Lie Detector" [9] states, fMRIs use electromagnets to create pulse sequences in the cells of the brain. The fMRI scanner then detects the different pulses and fields that are used to distinguish tissue structures and the distinction between layers of the brain, matter type, and the ability to see growths.
Lie detector is the popular term for a polygraph, a device that measures and records physiological indices, under the belief that these are useful for lie detection. Lie Detector may also refer to: Silent Talker Lie Detector, an alternative to the polygraph, invented between 2000 and 2002; Lie Detector, a 2005 show on PAX TV; Lie Detectors, an ...
