PDF protection based on user's PC hardware id.

Hello!

I am looking for a Adobe solution to protect my PDF files from spreading across the web. 

So, I am making learning material for students and teachers and would like to protect the concret copy of the PDF file from opening on other PC then a customer one. In other words I would like the protection based on user's PC hardware id. If anybody will get this file and will try to open it with the password so it will not be possible to do on other PC. It is some kind of DRM system.

Thank you in advance.
