Fake video clips made with machine learning algorithms can be spotted using AI, too.
Some background: The most common technique for generating fake videos involves using a technique called deep learning to swap one person’s face onto another individual—a trick also known as “deepfakes.”
The news: Through a Defense Advanced Research Projects Agency (DARPA) run program called Media Forensics, experts have made tools to detect videos manipulated using machine learning. One technique relies on the fact that faces made using deepfakes rarely, if ever, blink. Other tools explored similar ideas, like watching for strange head movements and odd eye color.
What’s next: As our own Will Knight writes, the arrival of these forensics tools may be the beginning of an AI-powered arms race between video forgers and digital sleuths. But the researchers aren’t revealing all of their tactics yet. “We have a little advantage over the forgers right now, and we want to keep that advantage,” says Siwei Lyu, a professor at the University of Albany, SUNY.
