Know which one is the lie? A new artificially intelligent camera system is picking up lies with the same accuracy as polygraph -- though those same habitual liars that con even the polygraph will likely still fool the system. The machine learning firm Tselia Data Lab recently developed a camera algorithm that detects lies based on facial signals -- and the work-in-progress already has a 75 percent accuracy rate. A high-definition camera focuses on the subject's facial features while software maps the changes in those facial features to pick up on subtleties like pupil dilation and facial tics, according to the Wall Street Journal. Fraudoscope, as the system is currently dubbed, starts much like a traditional polygraph with a set of calibration questions with a well-known answer.
