Protecting a PDF
Hi
I was wondering if any of you have experience with protecting PDF files?
What i want to do, is somehow stop the editing of the PDF, and not allow copy and paste.
It would be a bonus if somehow i can stop the PDF been distributed around too, but how hard/expensive is this?
It too would be great if there was an easy way to add somesort of watermark to each page, for example, the persons email address to put them off passing it around.
In short, it be great if the only way they can copy it, was to litrually type it out word for word.
Looked over google, bing, etc, and found a million and one things, so just wondering if anyone can save me time and recommend a way or product to do this?
Thanks
