Fake image detection based on fact checking

Manipulated videos, audio and images have been around for years, but the increase in access to photo apps in recent years have made it easier for anyone to create fake images/videos. Meanwhile, the rise of artificial intelligence and advanced editing software have made them much harder to spot. O...
