Lie Detector Test in Aachen | Professional Polygraph Services

Lie detector

A lie detector, also known as a polygraph, is a method that measures physiological responses such as heart rate, blood pressure, breathing, and skin conductivity to help determine whether a person is telling the truth. During the examination, the examinee is asked a series of questions while the polygraph records physiological changes that may indicate stress responses associated with deception

StimulTest

StimulTest enables remote truth verification through an online examination without the need for traditional polygraph testing. The system also helps assess a person's credibility, reliability, behavioral predictability, underlying motives, and the likelihood of future actions, providing valuable insights for both personal and professional decision-making.

EyeDetect

EyeDetect is a next-generation lie detection system that analyzes subtle eye movements to identify signs of deception. Scientific studies have reported accuracy rates of approximately 86–90%, depending on the testing protocol and conditions. The technology was developed in 2003 by internationally recognized researchers at the University of Utah and has since become one of the world's leading eye-tracking credibility assessment systems.
