It sure is an interesting area of research.

You might be interested in hearing about a parallel move - for creators to (invisibly) 'watermark' images so that people identify if their images have been adapted used by others - I'm not 100% sure but it might even be apparent if AI has utilized it too. I do remember that it's FOSS and up to the creator to do to protect their copyright.

There's also a seperate move to 'taint' AI's well of images that they might use.

When these purposely 'tainted' images are used by AI some objects are transformed into things like dogs - against both the AI algorithm's and end-user's wish. The idea, I believe, is to really mess with the AI's output. A 21st century sabot (clog) in AI's wheels as it were...

I'll try and find a source on it and write a post - but as you can imagine, unless I've bookmarked it, there'll be many more people separately writing about putting dogs in images on purpose too.
