Abstract
A Modular Video Authentication System (MVAS) has been designed for use with almost any video surveillance system. MVAS hardware is a standalone system that is packaged in individual 20 cm by 10 cm by 3.8 cm modules that allow for easy system integration. The MVAS can be used to authenticate the transmission of any realtime analog video signal. The microprocessor control circuitry packaged on two small printed wiring boards can monitor for the substitution of false video images inserted into any video transmission link. A video Processing Module is required at the transmission end of the link and an Verifier Module is required at the receiving end. Both modules operate from 12 volts DC and are essentially identical except for software. The \"autfienficatfdn signals are multipTexed into the video signal. A unique Programmable Read-Only- Memory (PROM) is used to protect the MVAS communication. The demonstration hardware shows how the MVAS hardware operates and how false video information is detected.
