Washington DC — Hey, did my congressman really say that? Is that really President Donald Trump on that video, or am I being duped?

New technology on the internet lets anyone make videos of real people appearing to say things they’ve never said.

Republicans and Democrats predict this high-tech way of putting words in someone’s mouth will become the latest weapon in disinformation wars against the United States and other Western democracies.

We’re not talking about lip-syncing videos.

This technology uses facial mapping and artificial intelligence to produce videos that appear so genuine it’s hard to spot the phonies. Lawmakers and intelligence officials worry that the bogus videos — called deepfakes — could be used to threaten national security or interfere in elections.

So far, that hasn’t happened, but experts say it’s not a question of if, but when.

“I expect that here in the United States we will start to see this content in the upcoming midterms and national election two years from now,” said Hany Farid, a digital forensics expert at Dartmouth College in Hanover, New Hampshire.

“The technology, of course, knows no borders, so I expect the impact to ripple around the globe.”
