Preventing the ability to copy a PDF file is a question I've seen often. I guess it can get a little confusing due to the security mechanisms embedded in a PDF document. The short answer is you CANNOT prevent a PDF file from being copied. You can password protect it so anyone without a password is not able to open it, but if you had given a PDF file with a password to someone, it can now be freely copied.
You will need DRM or document control solutions in place to do any more than that.

Hello,
ReplyDeleteNice blog! You can prevent users from copying text, images and graphics from a PDF file by modifying the document's security settings in Adobe Acrobat. Thank you...
