I came across tools like nightshade that can poison images. That way, if someone steals an artist's work to train their AI, it learns the wrong stuff and can potentially begin spewing gibberish.

Is there something that I can use on PDFs? There are two scenarios for me:

Content that I already created that is available as a pdf.
I use LaTeX to make new documents and I want to poison those from scratch if possible rather than an ad hoc step once the PDF is created.

Image poisoning's general principle is to change pixels in a way were our eye can't notice, but that screw up the labeling by LLMs.

You can probably try to apply the same principle, poison the PDF in a way that only humans can read it.

Thing is, I assume you distribute your content on PDFs to make the content accessible to humans. That usually means having the text embedded for easy copy-paste and similar methods. Poisoning these might end up being counterproductive for your objective.

All this to say that No, I have no idea of a poisoning algorithm for PDFs
