Abstract: An electronic license plate and information processing system allows for a vehicle license plate to serve not only the purpose of identifying a specifically associated vehicle, but to also serve as a media for publishing temporal messages specifically associated with the vehicle or its locale. A license plate assembly consisting of a microprocessor chip in communication with a radio frequency transponder serves to control a light emitting diode matrix or other similar display and to publish messages therethrough in accordance with data and commands received from the transponder. The various information sources, including a department of motor vehicles, law enforcement, insurance records, and public service agencies are capable of communicating with the electronic license plate through encrypted transmission. The control server is interposed between these various sources and the interactive license plate for effecting the desired transmission and receipt of data and commands.
