How can I
create a Word document that cannot be copied or modified?
Rule number 1 - If they can read it, they can copy it.
Rule number 2 - If they can copy it, they can modify it.
All you can do is make it harder.
The best way to distribute something you don't want modified is as a protected
pdf. I think you will need Adobe Acrobat for this. (The above rules still apply.) A Word
document, even protected, is going to have metadata in it and is designed for
editing. A pdf file is designed for reading. The above rules still apply with
pdf files, but you have made it harder.
Any protection method will only keep honest (or lazy) people from copying or
modifying your document. Locks are there to help keep honest people honest.
Rule 1 explained. If they can see it they can copy it.
Having access to a printer and scanner a document can be
printed, scanned, put through OCR and reproduced. It will take some tweaking.
Without a printer, a person can take a screenshot. A viewer can take a picture
with a phone. If they only have a paper
copy, they can make a photocopy, or, if need be, they can take out a paper and
pencil and write it down. With only a paper copy in a secure room, they can memorize it and reproduce it elsewhere.
be hard, but it is not impossible. All you can do is make it more
difficult. The best solution is to give the
document only to people you trust.
The problem with unwanted copies did not start with computers or
copy machines. Counterfeiting of currency and other documents has
long been a problem; it remains a problem.
Rule 2 explained. If they can copy it, they can edit/modify it.
This is essentially a corollary. If it is copied, it can be scanned with
OCR or retyped. Then it can be edited.
OK - So if they really want to do it, I can't stop them. What tools do I
have in Word to make it harder?
All versions of Word beginning with Word 97:
You can protect the document for forms. Even though it is
not a form and has no form fields you can apply protection for forms and
give it a password. For most users this means that they cannot select any
text so they can't copy and paste.
You can add features like document properties and document
variables to a document. This does not keep someone from copying it, it just
makes it more likely that you can detect a copy or modification.
If someone knows what they are doing, this protection can be
broken in less than 90 seconds. No, I'm not going to tell you how. That is
an exercise left for the student.
Hint: I learned how to do this on the
Internet. Our courts publish mandatory forms for lawyers to use. They are
poorly designed so they are hard to use but they are password protected
Word forms. I learned how to do this so I could make the forms easy for me to
use, not to change the content of the form. It took some searching but the
method is out there.
You can add macros to make copying/printing very difficult.
Macros are easily circumvented by setting the system to not run them. For
one document I designed a macro so that the content could not be viewed
unless macros were allowed to run. This is not very practical and can still
Word 2003 and later
There are various forms of protection including password
protection from opening to allowing editing only on parts. All of these are
subject to Rules 1 and 2. I may write more about these later. The password
for opening is very secure, it takes you back to rule 1: only show documents
to people you trust.
Word 2007 and later
You can apply very strong editing restrictions. These can be
found under the Developer Tab
or under the Review Tab. Again these make editing harder, not impossible!
