A new AI that detects "deception" may bring an end to lying as we know it

Being able to tell when a person is lying is an important part of everyday life, but it's even more crucial in a courtroom. People may vow under oath that they will tell the truth, but they don't always adhere to that promise, and the ability to spot those lies can literally be the difference between a verdict of innocent or guilty. To address this issue, researchers from the University of Maryland (UMD) developed the Deception Analysis and Reasoning Engine (DARE), a system that uses artificial intelligence (AI) to autonomously detect deception in courtroom trial videos. The team of UMD computer science researchers led by Center for Automation Research (CfAR) chair Larry Davis describe their AI that detects deception in a study that's still to be peer-reviewed. DARE was taught to look for and classify human micro-expressions, such as "lips protruded" or "eyebrows frown," as well as analyze audio frequency for revealing vocal patterns that indicate whether a person is lying or not.
