Security and printing of specific pages

I am developing a line of publications for our company and they want them to be
secure from copying but allow them to be able to print specific pages. Is this
possible? If so, how?

Also, in light of an earlier post on breaking security, is there a way to
prevent this? I thought 128 bit was secure.

I recommend you post in the Acrobat forum, but I think you will find
the answers are no and no.

The answers are maybe (but with a fair bit of hassle) and it depends.

For Acrobat and Reader permissions apply to a document as a whole, ie there are
specific page level permissions. However if you split the documents with pages
that can be printed, and documents with pages that can be printed. You can the
combine the two (or more than two depending upon how you split it up) document
back into a package (From Acrobat 8 - File->Combine Files..., Select
Documents, when asked to either Combine into single PDF or put into a Package,
choose Package). The resulting file will only work well in Acrobat 8 and above
and the user experience may not be what you were hoping for, but I'd play with
it to find out.

Now if for the question of it is secure - it depends. The key length used is
beside the point for DRM because the key to decrypt the content must exist on
the user's machine which means this is a clear example of the currently unsolved
CS problem of running trusted code on an untrusted host. (ie the strength of the
algorithm doesn't matter because the attack comes through key recovery not
through brute forcing the algorithm). For Password security on PDF files where
you choose to only use a Permissions password and not an Open password (the most
common case for over the Web distribution with some protection), this is
actually worse, since the algorithm to generate the password to open the file in
this case is published as part of the PDF Specification and because of this
there are any number of tools available to remove permissions on these files.
(If you have an open password this is still as secure as the combination of the
password you used and the underlying algorithm).

Oops, should've proof read better. First sentence of second paragraph should
read:

aren't specific page level permissions

Ok, you just re affirmed my suspicions. As for the watermarking, I will look
into that as a possibility.
