[liberationtech] Auto expiring document/files & 'rights to be forgotten'

Let's say the information was within a PDF, but the person(s) creating
it wanted it to expire at future date and be technically irrecoverable
say through encryption, irregardless of whether printed or memorised, is
it technically possible at little or no cost? 

Apologies if I come across as naive, it is being built upon the
widespread use of DRM, that currently is too prohibitive in cost terms.
I don't want to post details of available DRM software safe to say it
costs around $1000 per user or hundreds or $'s per month for server
based authentication services.

Does it involve people without printers? Or memories?
