SEAL protects public face photos from fine-tuning-based diffusion personalization by optimizing a sparse set of perturbed pixel locations, using latent-variance disruption and a facial-saliency penalty. On VGGFace2 with Stable Diffusion 2.1 and DreamBooth, it modifies 5% of locations and reports PSNR 41.08 dB, SSIM 0.97, LPIPS 0.07, and ISM 0.15 under P2. It does not protect encoder-based personalization.
