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.
**See Section 5 in our paper for a discussion of the intended use cases for (as well as limitations of) this tool.**

*First, let's edit your image:*
+ Upload an image (or select from the examples below)
+ Use the brush to mask the parts of the image you want to keep unedited (e.g., faces of people)
+ Add a prompt to guide the edit (see examples below)
+ Play with the seed and click submit until you get a realistic edit that you are happy with (we provided good example seeds for you below)
*Now, let's immunize your image and try again:*
+ Click on the "Immunize" button, then submit.
+ You will get an immunized version of the image (which should look essentially identical to the original one) as well as its edited version (which should now look rather unrealistic)
