I have some book (with permission) and want to sell it on CD for our non-profit organization. However, I am concerned about someone copying the file or the CD and reproducing it. I would like an affordable software program ?

Solution

A-PDF Password Security can protect pdf documents from copying, printing and distribution PDFs.

A-PDF Password Security is specially designed for pdf users to protect pdf files from copying with 40/128 bit RC4 and 128 AES encryption, therefore, if you set a password, then other people cannot print, copy or change the content of the file without the password. You can set up a monitored directory in which all the PDF files are encrypted, and you can contrarily remove the standard password security from protected PDF files.
