New watermarking technique for diffusion models preserves fidelity

Researchers have developed a new method called Latent Angular Watermarking (LAW) for embedding robust watermarks into diffusion models. This technique operates in the latent space, ensuring it doesn't interfere with the model's parameters or generation process. LAW addresses issues like the violation of latent Gaussianity and i.i.d. conditions, which can degrade generation fidelity and make watermarks vulnerable to removal. The method encodes watermark bits as antipodal angles between latent elements, with a magnitude-driven variant (LAW-M) offering enhanced robustness by anchoring bits in stable dimensions. AI
