System of controlled certificate production and management

摘要

Techniques are described for distributed production of controlled certificates, such as license plates for motor vehicles, in a secure manner. Controlled certificates may be printed at a local branch office subject to the control of a client computer. A server computer may regulate the operations of the client computers at the branch offices. The production system includes any of several security features to deter forgery and counterfeiting. For example, the security components that make up a finished controlled certificate may be separately secured with unique security elements. The finished controlled certificate may also have a unique security element.
