If you download a paper you should know that it has a unique fingerprint. If your cloud gets hacked, and the paper released with your “signature”, it affects you.
Yeah, it should be clearly visible. E-books bought from certain shops come with a notice like “This copy was bought by Tiuku” on the first page (and probably have something like this embedded as well). When it’s done in the open like this, I think it’s a pretty fair way of doing DRM.
Is it ‚really‘ fair, though?
