Prevent Save & Disable Save As

Probably the simplest way to make a copy of a file is to open it (wherever it happens to be) and then Save it to where you want a copy.  Some applications even help you by making copies on the local drive without even asking.

So if you want to preserve DRM you must prevent Save and prevent Save As from taking place either at the user's choice or because of applications design.

Some techniques, such as plug-ins, try to prevent Save and prevent Save As by trying to disable Save in pdf (and disable Save As pdf) by altering the code in the main application.  This is not a good approach because anything being disabled by one plug-in may be enabled by another.  And because all the functionality is still there the hacker is not stopped.

The simplest way to disable save and disable save as is not to have the code to do that present at all.  The same goes with disable save pdf and disable save as pdf, and that means not using one of the pdf viewers.  LockLizard Safeguard viewers prevent save and prevent save as by this approach since it is impossible to use code that is not there.

It is important to recall that when you prevent Save and prevent Save As you are not stopping people from making copies of the original file(s) by using the copy command from Windows File Explorer.  But you prevent Save and prevent Save As so that a copy cannot be made without the DRM controls, or in a format that may not apply DRM controls (text files or picture files perhaps).  For files that rely on access control mechanisms (non- DRM protected files), you prevent Save and prevent Save As so that files cannot be moved to different locations, such as memory sticks or servers or network drives, where the access controls may be very different.

There are other ways of copying the contents of a document, but if you can prevent Save and prevent Save As then you will have stopped the simplest and most effective way of making copies of documents.
