The team trained a convolutional neural network (CNN) to spot changes in images made with Photoshop’s Face Away Liquify feature, which was designed to change people’s eyes, mouth and other facial features. When put to the test, the neural network detected altered images up to 99 percent of the time. In comparison, people who saw the same photos only spotted the changes 53 percent of the time. The tool was also able to revert images to what it predicted was their original state.

This isn’t the first time, Adobe has used AI to spot photoshopped images, but this work is specifically targeted at detecting facial manipulation. The company says the work is more pressing than ever. “We live in a world where it’s becoming harder to trust the digital information we consume,” said Adobe researcher Richard Zhang. And when it comes to spotting manipulated images and altered faces, Adobe says this is just the beginning.
