I made a PDF from a Microsoft Word document. So far so good. Now what is the best way to protect my PDF eBook to ensure I don't get thousands of unauthorized copies of my PDF eBook floating around the internet?
I don't want to use a simple password to protect the PDF document, because judging by the amount of unauthorized PDF copies of other eBooks I have seen available on the internet, that security method is very weak.

DoPDF does not contain this functionality. You can try novaPDF, our commercial version instead as it does contain security features as explained here : http://www.novapdf.com/kb/password-prot ... nt-55.html
