Perhaps you can use policy-protected (encrypted) PDFs by deploying DRM solutions like Adobe LiveCycle. But they are not cheap. On the other hand, there is no protection of opening a PDF in a browser and then take screenshots of each page (or just photograph each page on the screen) and then OCR them and recreate PDF. So, legal way as George Johnson suggested is perhaps the way to go.
Thank you for the response George and Isakten.
I found my solution, and better yet it will not break the budget. CopySafe PDF Protector while perhaps a bit unwieldy for a first-time end user, offers all I needed. It forces the end user to add an add-on for their browser and we all know that can be difficult at best, but the program takes care of it handily.
