I have an issue which I need assistance with please.
I can secure a PDF file using Adobe Acrobat XI and it disables it from being copied and pasted (right-click brings no such options) but, when I upload it online (to Wordpress) and link to it then it opens in Adobe Reader (or whatever PDF viewer the user has installed on their computer) and because of this they can highlight the text and right-click and then copy and paste it to a Word document and such, even though this was not possible in Adobe Acrobat XI but as soon as it goes online it is possible. How can this be prevented?
Basically I want to embed PDF's online for others to read and view directly online but I want to disable them from copying and pasting text - can this be done?
Many thanks.
Ian
