Rel-Zero: Harnessing Patch-Pair Invariance for Robust Zero-Watermarking Against AI Editing

CVPR 2026

Recent advancements in diffusion-based image editing pose a significant threat to the authenticity of digital visual content. Traditional embedding-based watermarking methods often introduce perceptible perturbations to maintain robustness, inevitably compromising visual fidelity. Meanwhile, existin

Rotation-Invariant Spherical Watermarking via Third-Order SO(3) Representation Coupling

ICML 2026poster

Reliable watermarking of panoramic imagery is fundamentally challenged by arbitrary 3D rotations. As panoramas are defined on the sphere, they naturally transform under the action of $SO(3)$, rendering conventional planar representations and augmentation-based robustness strategies inadequate and de…

PlugMark: A Plug-in Zero-Watermarking Framework for Diffusion Models

ICCV 2025poster

Diffusion models have significantly advanced the field of image synthesis, making the protection of their intellectual property (IP) a critical concern. Existing IP protection methods primarily focus on embedding watermarks into generated images by altering the structure of the diffusion process. Ho…
