Generative image modeling enables a wide range of applications but raises
ethical concerns about responsible deployment. This paper introduces an active
strategy combining image watermarking and Latent Diffusion Models. The goal is
for all generated images to conceal an invisible watermark allowing for future
detection and/or identification. The method quickly fine-tunes the latent
decoder of the image generator, conditioned on a binary signature. A
pre-trained watermark extractor recovers the hidden signature from any
generated image and a statistical test then determines whether it comes from
the generative model. We evaluate the invisibility and robustness of the
watermarks on a variety of generation tasks, showing that Stable Signature
works even after the images are modified. For instance, it detects the origin
of an image generated from a text prompt, then cropped to keep $10\%$ of the
content, with $90$+$\%$ accuracy at a false positive rate below 10$^{-6}$.

本文提出了一种将图像水印和潜在扩散模型相结合的主动策略，以实现所有生成的图像具有隐匿的水印，从而便于将来的检测和 / 或识别，评估了水印在各种生成任务中的隐身性和鲁棒性，显示稳定签名即使在被修改之后仍可使用，能够在误识率低于 10 的负 6 次方以下时，准确率达到 90% 以上，能够检测文本提示生成的图像来源并对图像进行裁剪处理的情况。
