“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.”
When an average person can create a realistic fake video of the president saying anything they want, Farid said, “we have entered a new world where it is going to be difficult to know how to believe what we see.” The reverse is a concern, too. People may dismiss as fake genuine footage, say of a real atrocity, to score political points.
Realizing the implications of the technology, the U.S. Defense Advanced Research Projects Agency is already two years into a four-year program to develop technologies that can detect fake images and videos. Right now, it takes extensive analysis to identify phony videos. It’s unclear if new ways to authenticate images or detect fakes will keep pace with deepfake technology.
