A doctored video of House Speaker Nancy Pelosi, in which she appears to be impaired, made the rounds on social media this week, picking up more than 2.5 million views on Facebook and demonstrating the power of what's called "deepfakes."
Hany Farid, a professor of computer science at the University of California Berkeley, told CBS News' Jeff Pegues that this video is just the tip of the iceberg of how videos and images can be manipulated.
"The video is really a pretty low tech fake," Farid said. "Most standard one is to take an image or a video of a person, candidate a president, and alter it to make it look like they are saying something that they never said..."
Professor Hany Farid has a joint appointment at UC Berkeley in the School of Information and EECS.
