I am asking a question regarding the processing of PDF. I am generating a PDF using RadPDFProcessing through asp.net mvc. I want to prevent users from copying my contents in PDF after they have downloaded it. I have added in watermark on my document but users are still able to copy and paste text in the pdf to a text document. I tried to look for related materials in the listed Telerik resources but to no avail.
How am I able to prevent users who download my PDF from copy pasting the content inside the pdf to another document?
Thanks in advance.
