Facebook takes on deepfakes

In September, Facebook sent out a strange casting call: We need all types of people to look into a webcam or phone camera and say very mundane things. The actors stood in bedrooms, hallways, and backyards, and they talked about topics such as the perils of junk food and the importance of arts education. It was a quick and easy gig-with an odd caveat. Facebook researchers would be altering the videos, extracting each person's face and fusing it onto another person's head. In other words, the participants had to agree to become deepfake characters.
