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

Thu Jan 26 10:47:39 PST 2012

Frank any of the suggestions you are making can be circumvented by using a
"screen capture" during the time of review to create a "copy" of the
document. much like a photocopy of even a black and white document is not
as good as the original, this screen capture will have lower resolution
than the original, but still functional.

that said can you clarify what types of documents you are talking about? we
need more information about the use case in order to discuss further.

Are you just looking to raise the bar of difficulty? If that is what you
are looking for i think its possible, making it impossible to copy and
archive would be pretty difficult, probably not doable.
