This week on Lawfare's Arbiters of Truth series on disinformation, Evelyn Douek and Quinta Jurecic spoke with Hany Farid, a professor at the University of California, Berkeley, whose work focuses on analyzing and identifying altered photo and video—what’s known as digital image forensics. Recently, he has done work on deep fakes—realistic synthetic media in which a person’s likeness is altered to show them doing or saying something they never did or said. He’s also helped develop technology used by platforms to identify and remove material related to child sexual abuse. They talked about how dangerous deep fakes really are, how much of that danger is the technology itself and how much of it has to do with how big platforms amplify incendiary content, and whether platforms should moderate disinformation and misinformation in the same aggressive way they take down sexually abusive material.
