If you have full PDF tools you can create an actual digital

Yes, I am aware of that (well not how it looks because I haven't
used digital signatures with PDFs).
I was just looking today for somewhere to buy a good personal
certificate (name, physical address and email address for example,
not just email address) and on both Verisign and Thawte I couldn't
find any thing resembling that. It needs to be one of the big CAs
that have their certificates distributed with the major operating
systems.
You don't need a certificate to use these fields. The process is
similar to creating a PGP key pair -- as long as only you know the
keyphrase, you own the signature.
I have been using the same scanned "graphic" signature on computer-
generated documents for 20 years. In fact, since an expert could
tell they were identical, I suspect I would be able to make a good
mitigating case should it be stolen and misused on some strange
document.
But how would you prove that someone stole it?
Certainly it wouldn't be ironclad proof, but it would serve as an
indication. Like a signature from a physical rubber stamp is
considered potentially more questionable than a pen-and-ink one.
