Lie detectors could soon sense micro-expressions using AI: Researchers

The invention is expected to pave its way into the private sector for vivid applications

The world is currently witnessing a wave of technological developments. One such technological breakthroughs has been achieved by scientists of the Tel Aviv University. Reports suggest that researchers in the University have recently announced discovering a new lie detector which examines facial muscles, making it unnoticeable to identify.  

As per reports, the study conducted has been published in ‘Brain and Behavior’. Apparently, the analysis is based on micro-expressions which disappear within 40 to 60 milliseconds because of which speed and accuracy play a vital role.  

Dino Levy, Behavioral Neuroscientist claimed that although the new lie detector using micro-expressions might not be the perfect type but is considered to be much better than the existing facial recognition technology.

Essentially, researchers conducted tests of the give-away indicators on 48 participants in the course of which people claimed experiencing twitching of cheek muscles or eyebrows.

Commenting on the potential results obtained, Levy stated that the new lie detector technology was able to detect lies in all the participants better than untrained human detectors. He also mentioned that the machine-learning algorithm could easily detect lies of the human counterparts who successfully tricked their partners.  

For the uninitiated, the lie detector functions on the basis of artificial intelligence and offers to bring more transparency in future. Besides, it can also be used at the borer to boost the security.

According to reliable sources, the new innovation also boasts of the ability to be used in the private sector for diverse applications including screening the insurance claims or over job applicants.

However, researchers are possibly facing criticism from human rights groups questioning the technology’s ability to effectively evaluate people’s intentions and its potential for discrimination.
