Imagine a world where deepfakes have become so good that no detection mechanism can unmask them as imposters. This would be a bonanza for criminals and malignant state actors: for example, these might use deepfakes to slander rival political candidates or frame inconvenient defenders of human rights.
This nightmare scenario isn’t real yet, but for years, methods for creating deepfakes have been locked in a ‘technological arms race’ against detection algorithms. And now, scientists have shown that deepfakes have gained a significant advantage: the lack of a pulse no longer gives them away.
“Here we show for the first time that recent high-quality deepfake videos can feature a realistic heartbeat and minute changes in the color of the face, which makes them much harder to detect,” said Dr Peter Eisert, a professor at the Humboldt University of Berlin, and the corresponding author of a new study in Frontiers in Imaging.
