In 2001, he published his first work with lie detection using a modified form of the Guilty Knowledge Test, which is sometimes used in polygraph tests. [3]

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.
