… Researchers at NYU Tandon propose a way to protect digital images and videos from misleading manipulation with an authenticating watermark. … “Unlike previously used watermarking techniques, these AI-learned artifacts can reveal not only the existence of photo manipulations, but also their character,” said Paweł Korus, a research assistant professor in the Department of Computer Science and Engineering at NYU Tandon. … “If the camera itself produces an image that is more sensitive to tampering, any adjustments will be detected with high probability,” said Nasir Memon, a professor of computer science and engineering at NYU Tandon.
