Getting started

Our code relies on the stable diffusion code on Hugging Face.

1. Clone our repo: git clone https://github.com/madrylab/photoguard.git

2. Install dependencies:

     conda create -n photoguard python=3.10
     conda activate photoguard
     pip install -r requirements.txt
     huggingface-cli login
   

3. You should now be all set! Check out our notebooks!

[New] Interactive demo

We created an interactive demo using gradio, and we are hosting it on this HuggingFace space.

However, for faster inference, you can run the demo locally on your machine! Simply do this:

conda activate photoguard
cd demo
python app.py

Generating high-quality fake images

The first step is we will walk you through how you can generate high quality fake images. Check out this notebook! The result will be such images:

See this notebook!

Simple photo-guarding (Encoder Attack):

Now, we describe the simplest form of photo safeguarding that we implement. In particular, we implement a simple PGD attack on the image embedding part of the stable diffusion model. We have two demos demonstrating the efficacy of such photo safeguarding method. The goal of both is to cause the stable diffusion model to generate something that is either unrealistic, or unrelated to the original image.

Photo-guarding against Image-to-Image pipelines

The first is the case where someone uses an image + prompt to modify the input image based on the prompt description.

See this notebook!

Photo-guarding against Inpainting pipelines

The second is the more interesting scenario where someone wants to edit parts of an existing image via inpainting. The generated images after immunization are clearly fake!

See this notebook!

Complex photo-guarding (Diffusion attack)

For more effective photo-guarding especially against image inpainting, we need to attack the stable diffusion model end-to-end. Now, the generated images after immunization are even more clearly fake than above!

See this notebook!

That's it! Please let us know if you have any questions. And check our paper for details about each of these attacks.
