Want to spot a deepfake video caller? Ask them to turn sideways


Researchers have discovered a surprisingly simple way to detect deepfake video calls: ask the suspect to turn sideways.

The trick was shared this week by Metaphysic.ai, a London-based startup behind the viral  Tom Cruise deepfakes.

The company used DeepFaceLive, a popular app for video deepfakes, to transform a volunteer into various celebrities.

Most of the recreations were impressive when they looked straight-ahead. But once the faces rotated a full 90-degrees, the images became distorted and the spell was broken.

The recreations clearly failed when at a sharp 90° profile. Credit:Metaphysic.ai
