Help Securing a PDF File
Posted on 2012-08-15
I just purchased a Digital ID/Certificate from GlobalSign, one of Adobe's CDS providers, so I can sign PDF files. I installed the drivers/certificates and was able to sign a test document. At the top of the file there was a blue banner that says "Certified by ..... Certificate issued by Global Sign".
The only problem is that the document is completely unprotected. By this I mean you can copy all the content you want, and even copy it as formatted. I suspect you could create an unsigned twin of the file by copying everything with formatting and pasting it into MS Word.
In the past, I used password security to prevent changes/copying/extraction of content. How do I get the best of both worlds? I want the final PDF signed by me with my GlobalSign ID. The only thing others should be able to do is print in high-res. There should be no copying, extraction, editing, etc.
I tried securing the document with a password, then signing it. The problem is once it is secure the option to sign wasn't available. Maybe I need to set the password security, then sign it without saving the document first. Would this make signature and restrictions stick?
I hope this whole Digital ID thing wasn't a waste it means anyone can essentially copy my content. Please help!
