Topic: check if document has been modified

I use to create my PDF docs dynamically, therefore when adding a signature to the document and click it
(the signature) I get "sign is UNKNOWN" and "....document has not been modified"
Since "sign is UNKNOWN" doesn't look good,
I'm looking for a way that mark the PDF if changes
where made to the document after it was published.
I heard that there is a way of placing a hidden gif that will show when the document has been modified.
Do you know of such way?
