What worries me is, what if they put in some obfudcated unique ID in the document that can be traced back to you? Is there a way to catch it with reasonable certainty?
I doubt OP is a publisher. Nobody goes after the little guy (except when they want to make an example of someone, but the odds of that happening to you are slim to none).
I regularly get materials with identifying information embedded in them, it’s very common in the technical publishing industry, not unreasonable to check a purchased eBook for an identifier which ties it back to the original purchaser.

you can view and edit every bit of metadata inside Calibre. If you want to make sure, go and edit the metadata there.
Yeah but what if the fingerprint is more tricky? Like a blank line with the font called afzer the fingerprint? Metadata inside of an image?
To be reasonable safe one would have to buy the book from multiple accounts and compare some hashes.
For fucks sake I’m pretty privacy conscious but you guys just take it too far
I’m pretty sure there was at least one publisher caught experimenting with this.
