Fingerprinting Text-to-Image Diffusion Models via Collapsed Generation

A non-invasive model fingerprinting framework based on collapsed generation, a phenomenon where certain input conditions produce highly consistent images across multiple stochastic seeds, is presented, establishing collapsed generation as a reliable intrinsic evidence source for non-invasive diffusion model ownership v...
