Smartphones can become lie detectors
A new machine learning algorithm analyzes your phone interactions to determine if you're being honest.
Computer scientists at the University of Copenhagen (Denmark) can identify lies by analyzing the way you swipe and tap on your smartphone screen. Dishonest interactions tend to last longer and involve more hand movements than honest interactions.
The algorithm, called Veritaps, flags truthful statements in green and questionable information in red. The scientists also created a test app that runs on Android phones, but it has not been released to the public.
Aske Mottelson, one of the study's authors, said the algorithm has lie-detection capabilities comparable to a polygraph. It has limitations, but vWith AI and machine learning technology, accuracy will be increased in the future.

The application can detect lies based on how quickly or slowly you operate the phone. |
People have long wanted to develop a device that can detect who is lying. The Polygraph, invented in 1921, is the most standard device when checking changes in heart rate, blood pressure, breathing... of the speaker, but also faces many criticisms about accuracy.
The startup Converus has also developed an EyeDetect analysis system based on eye movements such as pupil dilation and blink rate. It has an accuracy rate of 86%, but it cannot replace the Polygraph.
