Hi Tony
This topic is often discussed in the newsgroups.
You're correct... sort of. Word was always designed to be an *editor*
-- a program for creating and modifying documents. Any efforts to make
Word documents uneditable are really fighting the nature if the thing.
PDF was designed as a display/print format. Unless you have the full
Acrobat authoring program, it is (or was, until recently) fairly hard
to modify an existing PDF file. There are now a number of programs,
mostly optical character recognition (OCR), that can easily turn a PDF
file into a Word file, making PDF considerably less secure than you
think. And it was always possibly to print the PDF and then scan/OCR
the paper copy.
The rule to remember is "if I can read your document, I can alter it."
The only electronic document that's really safe from tampering is the
one you never send to anyone. If it's a matter of legal proof, use
paper or escrow the documents with a third party.
So you're saying that the following scenario cannot be had:
I create a contract of some sort, protect it, email it to a client, have them
print it out, sign it and send it back to me via snail mail. I have no way of
knowing if an "or" was changed to "and" somewhere in the document by
any means available. OK, understood.
But what if I just wanted it to be NOT SO EASY to exploit? Couldn't it
be made much more simpler than IRM? What does IRM get me that
some kind of password read-only protection couldn't get me? The problem
with "read-only" in Word is that it's still copyable and saveable, especially
form fields are hard to protect. Why can't MS implement real read-only
where no caret would even show up in the doc and no cut-n-paste or save
as another file would be allowed without the password? Isn't this very
fundamental (sending a contract or other document to someone outside
of the company!)? I just don't understand why it has to be so difficult and
so imposing on authors and recipients (I need a service to send a read-only
doc or receive one? Ouch!).
I'm trying to give a client of mine this functionality and am now looking at
conversion to PDF via a print driver as a simpler solution than IRM to
get read-only functionality. If I would have known this would become an
issue, I may have chosen Acrobat to begin with rather than Word.
Certainly I'm going to be asked by the client why I selected Word in the
first place if we end up converting to PDF in then end.
