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 converted a pdf book scan to epub with tessaract ocr and calibre, it didn't need any programming, but the end result did have a typo every few paragraphs. Most were very similar to each other though, so a few hours cleaning it up would've made it pretty readable.
