Licensing PDFs

by Rosie Evans / March 12, 2008 9:51 PM PDT


We want to license some of our documents for electronic use, we thought this would be done best as PDFs. However, the problem we have is that we want the user to be able to edit the documents for their own purposes - as such they will need to be able to save this version but we do not want them to be able to save the original document. We also want to limit the number of documents they can create from our template. For example, they may pay for 10 licenses so we would want the document to expire after 10 copies had been produced from the template.

Can anyone offer any advice on how to go about this or if it is even possible?

And what would happen ...

if, after the document somehow expired after being used 10 times, they replaced it with their original backup copy? For all purposes, including any general purpose editor, it would be the original that could be used 10 times. Ad infinitum.

So I think this can't be done without using some form of DRM (Digital Rights Management). Like you can make 3 copies of a mp3-file you paid for. But that's beyond this forum.

Hi Kees,

Thanks for your help, I don't suppose you are able to tell me a bit more about Digital Rights Management?

Thanks, Rosie

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
