Abstract
A system and method are provided for producing verified signatures on documents such as checks and affidavits. Initially, a customer who is to obtain a verified signature, at some point in time, registers with a signatory authority, and a secret key, having public and private components, is established uniquely for that customer. When a document requires a verified signature, the customer presents the document and proof of his/her identity, such as a preprogrammed computer-interfacable card, to a signature system. Typically, such a system is to be available at an institution, such as an office, bank, or post office, where such services will routinely be used. The system accesses the archive of the private portion of the customer's key, and generates an encoded signature based, in part, on the content of the document. Accordingly, when a recipient of the document later wishes to verify the signature, the recipient uses the customer's public key to decode the signature. It is then straightforward to verify the signature against the content of the document.
