With digital signatures, how can you insure that noone "steals" your signature and uses it for a form of identify theft by opening an account, charge card, or withdrawing money from your bank account, etc.? Has something like this occurred before?

My Product Information:
Acrobat Standard 8.1.1, Windows

Acrobat uses special certificates that are either provided by a trusted site or created from within Acrobat/Reader. The user has unique password for accessing the signing certificate and the other party can verify the signature by access the trusted site or validating against a public certificate with just enough information to validate the signature field but not recreate the signature certificate.

My name is Olga and I work for a company that specializes in digital signatures. Basically in order to steel your signature the person has to know your access password.
If you're interested, there's some useful background (non-commercial) information about digital signatures at http://www.arx.com/digital-signatures-faq.php
