Definition: FakeCatcher


Software from Intel that determines if a video is a fake or not. Operating in real time, FakeCatcher uses photoplethysmography (PPG), which uses light to analyze the blood flow in a person's face. As the heart pumps blood, a person's veins change color, and FakeCatcher analyzes 32 areas on the face as the person speaks. See deepfake.
