Abstract
A method of controlling the use of a custom image by a user in a value dispensing system, such as a mail processing system, that enables the system provider to account and charge for the use of the custom image without ever actually receiving the data representing custom image. The method includes steps of receiving a hash generated from at least the custom image at a provider location, such as a data center, generating a digital signature from data including at least the received hash, and transmitting the digital signature and data used to generate the digital signature to the user at a user location. The method may further include additional steps of determining whether the digital signature can be successfully verified, and allowing the custom image to be printed by the user only if it is determined that the digital signature can be successfully verified.
