Researchers have developed a novel method to authenticate real videos against AI-generated content by leveraging the Moiré effect. This physical signature, produced by the interference fringes when a camera views a specific grating structure, is naturally present in real footage but difficult for current AI video generators to replicate. The proposed Moiré motion invariant demonstrates that the correlation between fringe phase and grating image displacement can reliably distinguish between authentic and synthesized videos. AI
