How to allow users to only open PDF file but not save them

How can I allow users to open PDF file but not save them. All User's PCs are using Windows and do not have admin permission. I remember when i downloaded Game Magazine via online they let me download certificate first so i could open the PDF Game Magazine. Can i do something like that? Or is there better solution?

The general rule is "whatever you give to the user is not yours anymore". So there's no reliable way to prevent saving. Adobe tried to implement some kind of DRM solution with its Reader, but it works only for Reader and any application or library that can open the PDF would be able to save the data (should the developers decide to ignore the flags in the PDF).
