ROBIN++: Unified Copyright Protection and Tamper Localization for Diffusion Models via Dual-Domain Synergistic Watermarking

Summary

ROBIN++ is a watermarking framework for diffusion models that aims to provide both copyright protection and tamper localization. It injects a frequency-domain copyright watermark during generation and a spatial-domain localization watermark in the latent space, then uses a dual-branch detector to verify both. The source reports that it significantly outperforms existing approaches in copyright recovery and tamper localization accuracy, though it gives no specific numbers in the text provided.
