Researchers have developed a new technique called cyclic denoising to probe image diffusion models for memorized training data. This method involves repeatedly applying forward and reverse diffusion processes at controlled noise levels, revealing "ultrastable memories" within the model. These memories can regenerate even after significant corruption and persist through thousands of cycles, often corresponding to specific training images like stock photos or watermarks. The attack requires only sampler-level control and does not need gradients, weight inspection, or prior knowledge of the training data, demonstrating its potential for privacy and copyright auditing.
