National: ‘Deepfake’ videos called new election threat, with no easy fix | Susannah George/San Francisco Chronicle
“Deepfake” videos pose a clear and growing threat to America’s national security, lawmakers and experts say. The question is what to do about it, and that’s not easily answered. A House Intelligence Committee hearing Thursday served up a public warning about the deceptive powers of artificial intelligence software and offered a sobering assessment of how fast the technology is outpacing efforts to stop it. With a crudely altered video of House Speaker Nancy Pelosi, D-San Francisco., fresh on everyone’s minds, lawmakers heard from experts how difficult it will be to combat these fakes and prevent them from being used to interfere in the 2020 election. “We don’t have a general solution,” said David Doermann, a former official with Defense Advanced Research Projects Agency. “This is a cat and a mouse game.” As the ability to detect such videos improves, so does the technology used to make them. The videos are made using facial mapping and artificial intelligence. The altered video of Pelosi, which was viewed more than 3 million times on social media, gave only a glimpse of what the technology can do. Experts dismissed the clip, which was slowed down to make it appear that Pelosi was slurring her words, as nothing more than a “cheap fake.”
