Computerized Polygraph Inventor Describes New Lie Detector

Dr. David Raskin — one of the foremost experts in polygraph and inventor of the world’s first computerized polygraph in 1991 — shares fascinating stories about working in this industry and how he became involved in developing a new lie detection technology called EyeDetect.

How does it work?

EyeDetect uses a high-definition, infrared eye-tracking camera to monitor involuntary eye behavior — including pupil dilation, blink rate, and fixations — to detect deception while a person answers true/false questions on a computer screen. The test takes 30 minutes and provides a “truthful” or “deceptive” score within 5 minutes. Polygraph exams, the long-time standard for lie detection, require a trained examiner, take at least 90 minutes to conduct, and reports can sometimes take hours to receive.

Field tests show EyeDetect is 86% accurate. When used in conjunction with the polygraph, and when both tests have the same result, the confidence in the test outcome can be as high as 99%. This is unheard of in the lie detection industry.

Most companies, in countries where it’s legal to administer lie detection tests in the workplace, use EyeDetect for pre-employment screening of job candidates and periodic testing of current employees. EyeDetect is not only ideal for screening job candidates in government, law enforcement and corrections, but also for screening visa applicants, immigrants, sex offenders, probationers, and parolees. For example, an important potential national security application of EyeDetect is screening Syrian refugees for terrorists.

Companies and government agencies throughout Latin America have been using EyeDetect since late 2014. Converus recently began offering EyeDetect to the U.S. market.

The main benefits of EyeDetect include:

  • High accuracy
  • Fast (only 30 minutes for a test)
  • Nonintrusive
  • Cost-effective
  • Portable
  • Incorruptible and unbiased

After the concept was conceived in 2002, a team of five scientists from the University of Utah spent more than 13 years fine-tuning this new ocular-motor based lie detection technology. Two of the five scientists, Drs. David Raskin and John Kircher, are not only world-renowned polygraph experts, but also credited with inventing the computerized polygraph.
