Depending on how technical and secure you're looking for, I'd say do
some poking around the bank/check industry. After all, they are quite
concerned with fraudulent documents getting around.
I forget the exact website but there is an entire site based on a secure
paper and printing/signing. Some Googling will probably reveal it. Once
again, depending on your exact worries and concerns, using special paper
might be overkill. However, I'll betcha the bank industry (along with
check books and such) will lead to a wealth of information.

i'm not impressed with banking technology when it comes to paper, and much
less impressed now that CHECK21 is being implemented.
banks have something that the rest of us don't: the rule and force of law.
aside from the usual laws that protect all of us against fraud, banks are
protected by special laws and special branches of law enforcement. when it
comes down to it, that may be a bigger deterrent against fraud than what
kind of ink or paper they're using.
from a security perspective, CHECK21 is a joke. i'm looking forward to the
first case where CHECK21 evidence is thrown out of court because it
amounts to hearsay, not physical evidence... and there's no chain of
custody.

really, if you want to have a digital signature on a piece of paper, the
only practical way i can think of is to scan it into a file and sign the
file. verification could then become a tedious process of comparing the
actual paper to the signed file, but it can be done. you still have to be
aware of other factors, such as who has access to the keys, etc.
