Public Policy Professor John Villasenor joined CNN London to discuss the growing threat of deepfake videos, which use artificial intelligence to alter images, swap faces or edit voice audio to create very realistic footage. In one example, a deepfake video was released showing British Prime Minister Boris Johnson appearing to endorse his political rival, Jeremy Corbyn. Villasenor explained that digital misinformation is a real concern in today’s political environment. “We can expect both here in the United States and in other countries that the technology that can be used for these deepfakes will, in some cases, be used in an attempt to influence elections,” he said. Villasenor explained that there are “subtle differences between the audio and the mouth movements, but you have to be looking carefully.” Moving forward, he urges people to “recalibrate their expectations” and unlearn the habit of assuming that what we see on video is always true.
