Handwritten Signature Security Issues

[dlw]

My boss wants me to do some research on any security issues with having
images of handwritten signatures on email signature blocks. I did a search
and did not come up with much. Can anyone point me to something?
My common sense answer is that anything you sign in the real world can be
scanned, and they have your signature, so what? Like every time you write a
check, your signature goes out to the world...

Security issues are with email as a communication media as a whole.
A scanned image wont wash in any legal sense

The only real issue with having the handwritten signature out there is that
the signature might allow someone to forge documents. Although the
probablity of someone using it to forge a signature is slim, I wouldn't put
it in given that there is no *real* business need to make it available.

What would happen if someone inside your company were to take the signature
and use it to forge a low-dollar value check request or approve an expense
report with questionable expenses? While the signature is available on a
variety of company documents, why chance fate and make it even more widely
available?
