Quote:
When generated according to the standard methods, UUIDs are, for practical purposes, unique. Their uniqueness does not depend on a central registration authority or coordination between the parties generating them, unlike most other numbering schemes. While the probability that a UUID will be duplicated is not zero, it is close enough to zero to be negligible.[2][3]
So if generated by Amazon it could be used as a watermark.

Is "uid" or "uuid" tag in .opf a watermark?

In the customization options of dedrm there is an option "remove watermark", to what extent does this work?
