Hi all,
My organization hosts an online learning community with video tutorials and printables. We're struggling to find a good way to protect PDFs from unwanted distribution. We'd like people to be able to view and print the documents, but not be able to share it on Facebook, email it out, or modify it. I know there's not a clear way to prevent downloading if printing is an option, but is there any way to authorize a file *only* for a specific group of users (in the thousands)? The closest I've seen is some sheet music providers, who watermark the PDF with your name after you purchase it.
Thanks for your help,
Jen
