Researchers have developed a new theoretical framework to understand the vulnerabilities of semantic watermarks in latent diffusion models (LDMs). Their analysis reveals that structural mismatches between different models create an irreducible distortion floor, limiting the fidelity of forged watermarks. This distortion manifests as geometric deviations on the latent manifold, rather than random noise. Based on these findings, the team proposes a detection method that can identify forged samples before watermark verification, demonstrating its effectiveness across various black-box scenarios. AI
