Researchers have developed GaitProtector, a novel framework for de-identifying gait patterns by simultaneously obscuring the original identity and impersonating a target identity. This method utilizes a training-free diffusion latent optimization pipeline, leveraging a pretrained 3D video diffusion model to generate protected gaits. Experiments demonstrate significant reductions in gait recognition accuracy while preserving visual and temporal quality, and maintaining utility for downstream diagnostic tasks. AI
