I know Calibre can remove DRM, but it seems that Calibre does not remove things like watermarks, references to the buyer by name, etc. Now maybe I can try to find those manually, but that is an error prone process. Plus, what if they embed a unique digital signature that ties back to me? I understand that this is a very uncommon practice, but I do not want to find myself in a bad place.

I suppose the only way to remove a digital signature of any sort is to buy two of the same e-book by different people, diff them, and remove anything that differentiates them.

Is there any tool that does this or automates the process? am I being too paranoid, and this is not a real threat?

I'm an idiot so excuse me if this is just way too simple. If you're able to remove DRM and get the file, is it not just possible to copy the content out of the file and make a brand new file?

I know I'm probably over simplifying things but I know if I'm paranoid about stuff like exif data in an image, if I'm in a pinch I'll just screenshot the original image instead.

What if the signature is embedded in the content and I missed it? Maybe it's just a hash in some footnote with white text color.

Screenshotting the photo would work, but it would be difficult doing that for every page.
