Application of invisible image watermarks to produce remotely printed, duplication resistant, and demonstrably authentic documents
Abstract
A complete Internet-based system for the remote production of verifiably-authentic and duplication-resistant documents is presented. This system has a reasonable and straightforward migration path to an eventual "all-digital" embodiment where completed transactions are acknowledged by sending an electronic receipt to the Client that has been signed with the electronic signature of the Originator.
