To prevent the spread of false information on its website, the large social media network Facebook plans to ban videos extensively altered by artificial intelligence technology. The company’s vice president of global policy management, Monica Bickert (at left in photo), announced that such videos, called deepfakes, would be banned when they are either in user’s posts or in advertisements. Subbarao Kambhampati, a Fulton Schools professor of computer science and leading artificial intelligence researcher, says automated systems for detecting deepfakes will likely have limited effectiveness and provide incentives for users to attempt to fool Facebook’s detection systems.
