Detecting deepfake videos: Fake videos pose a grave threat to the 2020 elections, writes Olivia Beavers, unless media adopt policies to tell real videos from forgeries.

“In the internet age, newsrooms have scrutinized images and videos to determine whether they are authentic or fake,” she writes. “But deepfakes will be a more difficult challenge, particularly because artificial intelligence makes the authenticity of such videos indistinguishable to the human eye and forgeries harder to detect.”
