According to computer scientists at the University of Buffalo, light reflections in the eye are the key to deciphering whether the person you're watching in a given image is genuine or a clever deepfake. There's a special tool that can automatically identify deepfake photos by analyzing light reflections in the subject's eyes. When used on portrait-like photos across a series of experiments, the tool achieved 94% efficacy when sussing out real photos from fakes. Experiments using the tool were written up in a paper accepted at the IEEE International Conference on Acoustics, Speech, and Signal Processing, which takes place in June in Toronto. The paper, "Exposing GAN-Generated Faces Using Inconsistent Corneal Specular Highlights," refers to generative adversary network (GAN) images, including those created by AI.
