Public Policy Professor John Villasenor spoke to Business Insider about “deepfakes,” phony videos and digital images manipulated using artificial intelligence. Easy access to both the technology to alter videos and the platforms to distribute them widely has heightened concern about deepfakes, Villsasenor said. “Everyone’s a global broadcaster now. So I think it’s those two things together that create a fundamentally different landscape than we had when Photoshop came out,” he said. Altered videos can be used in satire and entertainment, creating complications for legal efforts to crack down on malicious users. Time constraints are also an issue, Villasenor said, citing deepfakes used in political attacks. “Election cycles are influenced over the course of sometimes days or even hours with social media, so if someone wants to take legal action that could take weeks or even months,” he said. “And in many cases, the damage may have already been done.”
