Below you can test our (encoder attack) immunization method for making images resistant to manipulation by Stable Diffusion. This immunization process forces the model to perform unrealistic edits.
<br />
**This is a research project and is not production-ready. See Section 5 in our paper for discussion on its limitations.**
<details closed>
<summary>Click for demo steps:</summary>
+ Upload an image (or select from the below examples!)
+ Mask (using the drawing tool) the parts of the image you want to maintain unedited (e.g., faces of people)
+ Add a prompt to edit the image accordingly (see examples below)
+ Play with the seed and click submit until you get a realistic edit that you are happy with (or use default seeds below)
Now let's immunize your image and try again!
+ Click on the "immunize" button, then submit.
+ You will get the immunized image (which looks identical to the original one) and the edited image, which is now hopefully unrealistic!
