Fake, but realistic celebrity porn videos showing popular actresses such as Emma Watson and Gal Gadot in explicit scenarios are being created using artificial intelligence.

As reported by Motherboard, “There’s a video of Gal Gadot having sex with her stepbrother on the internet. But it’s not really Gadot’s body, and it’s barely her own face. It’s an approximation, face-swapped to look like she’s performing in an existing incest-themed porn video.”

“The video was created with a machine learning algorithm, using easily accessible materials and open-source code that anyone with a working knowledge of deep learning algorithms could put together,” they explained, adding that the fake videos are being created by a single Reddit user.

The user, a programmer who goes by the name “deepfakes,” has also created fake porn videos featuring Scarlett Johansson, Maisie Williams, and Aubrey Plaza.

“I just found a clever way to do face-swap,” declared the programmer in an interview with Motherboard. “With hundreds of face images, I can easily generate millions of distorted images to train the network… After that if I feed the network someone else’s face, the network will think it’s just another distorted image and try to make it look like the training face.”

“Every technology can be used with bad motivations, and it’s impossible to stop that,” he continued. “The main difference is how easy [it is] to do that by everyone. I don’t think it’s a bad thing for more average people [to] engage in machine learning research.”

The videos, which all vary in quality, can be found on Reddit, where the posts have been upvoted hundreds, and sometimes even thousands, of times.
