Does anyone know of any free resource that can make a PDF document, for
instance, inaccessible after a certain data, Most Digital Rights
Management (DRM) software prices are too prohibitive to make them a
practical solution to individuals.

This request is being prompted by a desire to find a practical way to
use rights to be forgotten, such as the new European Data Protection
proposals on

Of course there are ways to overcome document based DRM, but an open
source version could be useful to at least add a layer of privacy
protection to documents shared online, particularly when they contain
personal identifiers that unwittingly could become a risk to individuals
at a later date.
