Current image immunization defense techniques against diffusion-based editing embed imperceptible noise in target images to disrupt editing models. However, these methods face scalability challenges, as they require time-consuming re-optimization for each image—taking hours for small batches. To address these challenges, we introduce DiffVax, a scalable, lightweight, and optimization-free framework for image immunization, specifically designed to prevent diffusion-based editing. Our approach enables effective generalization to unseen content, reducing computational costs and cutting immunization time from days to milliseconds—achieving a 250,000$\times$ speedup. This is achieved through a loss term that ensures the failure of editing attempts and the imperceptibility of the perturbations. Extensive qualitative and quantitative results demonstrate that our model is scalable, optimization-free, adaptable to various diffusion-based editing tools, robust against counter-attacks, and, for the first time, effectively protects video content from editing. Our code and qualitative results are provided in the supplementary.

Our process begins with the immunizer model $f(\cdot;\theta)$ which generates imperceptible noise $\epsilon_{im}$ to be applied to original image $I$. This noise is applied to the masked region $M$ of the image, resulting in immunized image $I_{im}$. The immunized image is then processed by a diffusion-based editing model $SD(\cdot)$ using a text prompt $P$ and the complementary mask $\sim M$ to edit the background of the original image. The training aims to minimize two loss terms $\mathcal{L}_{noise}$ and $\mathcal{L}_{edit}$, which penalizes the applied noise magnitude, and if the edit is successful, respectively. During training, the immunizer learns to generalize across diverse images, ensuring editing attempts fail while preserving visual fidelity. This end-to-end framework enables robust, scalable immunization against diffusion-based editing for both images and videos. |
