I think if you print the PDF to another PDF, it'll lose any copy protection or potential identifiers.
Can anyone confirm this? Would make the whole process very macroable
The easiest way to confirm this would be:
This obviously assumes that you know exactly what metadata you want to eliminate and how to view it.
The OP’s whole point of asking is that they don't know the former.
This, essentially. Like until I tried to move music from iTunes to Foobar, I didn’t learn that metadata was even a thing, and apparently neither does Apple.
If you use ghostscript, it absolutely should, but you're probably better off using something like cpdf.
Buy two PDFs with different accounts and hash the result?
Adobe and Microsoft PDF printers retain some information. If you run it through ghostscript you'll get only the PostScript output. You can use a free utility like cutepdf to make it easy. Just install the latest gs release after installing cutepdf instead of the download they provide.
I imagine this destroys hyperlinks. Maybe machine-readable text too
