Non Savable File format?

Question

I have a *.DOC file which I want to convert in to file format which cannot be saved or copied on any other computer,which one can only read?

Answer 1

That is not possible with the standard windows operating system. If you were to implement Digital Rights Management you could get close (it would be unusable, but still able to be copied).

There are other options however, things like bitarmor (cost money of course) allow you to assign a password to allow access.  If the password is strong enough, even if it's copied, it would be useless.
