Researchers have developed a new method to determine the origin of images, focusing on whether pixels alone can reveal if an image was created by a human, an AI class, or a specific generator. The study frames this as a robustness problem under adversarial distribution shifts, establishing a statistical limit for image-only verifiers. Experiments on real and diffusion benchmarks showed that public CLIP verifiers failed under targeted pixel attacks, while a ResNet-18 model exhibited partial fake-to-real transfer, indicating a need to evaluate both the statistical ceiling and the information released by deployed verifiers.
