How to Protect Your eDocument

[zo_oz]

Hi,

When customers buy an e-document (in PDF or word) online, is there a way I could imprint customers’ partial information (such as first name and last name) as footer in the document without letting customers alter the document later? I believe with Adobe Acrobat 9, you could do prevent people from altering/copying/printing document, but could you dynamically imprint information into the document?

Any thoughts would be greatly appreciated. Many thanks!!
