Here's how an AI lie detector can tell when you're fibbing

Deception detection meets artificial intelligence.
By Rob Verger November 2, 2018


Researchers have trained AI on data representing both truth and falsehood.


Artificial intelligence is everywhere—it figures out what’s in the food photos on sites like Yelp, it helps researchers attempt to make MRI scans faster, and it can even look for signs of depression in someone’s voice. But here’s a use you may not have considered: lie detection.


That idea—an AI fib sniffer—is in the news because of a border security project in Europe called iBorderCtrl that involves technology focused on “deception detection.” The initiative includes a two-step process, and the lie-detection part happens at home. According to the European Commission, the protocol begins with a pre-screening in which voyagers “use a webcam to answer questions from a computer-animated border guard, personalised to the traveller’s gender, ethnicity and language. The unique approach to ‘deception detection’ analyses the micro-expressions of travellers to figure out if the interviewee is lying.”
