Facebook's newly announced ban on deepfake videos presents a number of challenges in the fight against the spread of misinformation, says Tim Weninger, associate professor in the Department of Computer Science and Engineering at the University of Notre Dame.
"This is good news for democracy and a good business policy for Facebook," says Weninger, an expert in disinformation and fake news, web and social media, data mining and machine learning. But the policy presents a host of problems and challenges.
"Most obvious is the technological question of how will Facebook determine which content is AI faked and which is not. It's clear that deepfake technology will soon be usable by the masses," Weninger says. "Facebook won't have the capacity to filter fake videos manually." Notre Dame and others are working on deepfake detectors, but the detectors won't catch everything, he says.
"Second is the actual effect that this deepfake ban will have on the actual problem. If a deepfake is created, shared, and quickly taken down, the damage is done — it will live forever."
