Explanation

A deepfake is an altered photo or video that's completely different from the original but still looks totally realistic. A film that appears to show your school principal winning the U.S. Open — it's probably a deepfake. Deepfakes are manipulated recordings that are made using artificial intelligence. Unlike older techniques for creating false images, deepfakes seem so authentic that you're not sure what's true and what isn't. They can be used for entertainment, to bring back long-dead Hollywood stars or swap characters from different movies. But deepfakes are often intended to deliberately mislead people by spreading fake (but real-looking) information. Deepfake was coined in 2017.
