A kind of Truth Machine
A called "Brain Fingerprinting" is in current use in the legal system. Brain Fingerprinting is based on reading a particular brain wave related to prior knowledge. Someone suspected of committing a crime is attached at a monitor and shown an image of the crime scene. The reading shows whether they have prior knowledge of the scene.

Brain Fingerprinting - Brief Summary of the Technology
Unlike the polygraph or lie detector to which it is often compared, the accuracy of this technology lies in its ability to pick up the electrical signal, known as a p300 wave, before the suspect has time to affect the output.
"It is highly scientific, brain fingerprinting doesn't have anything to do with the emotions, whether a person is sweating or not; it simply detects scientifically if that information is stored in the brain," says Dr Farwell.
"It doesn't depend upon the subjective interpretation of the person conducting the test. The computer monitors the information and comes up with information present or information absent."
Brain fingerprinting is admissible in court for use in identifying or exonerating individuals in the US.
