      Good morning, I need to prevent people from exchanging Pdf files. I want to sell to my students a textbook in pdf, but I want to prevent them from exchanign the files. I have secured the files, but people still are able to copy the entire file and paste it in an other directory, or hard disk or USB.

      How can I do?

      Thanks for your help,
