  • Anti-tampering method and corresponding circuits and electric systems
    Patent number: 6069410
    Abstract: An anti-tampering circuit for a vehicle includes an operational circuit providing a predetermined function for the vehicle to be protected, and a control circuit connected to the operational circuit for enabling and disabling operation thereof. The control circuit includes a semiconductor substrate, a communications circuit formed on the semiconductor substrate receiving data corresponding to an identification code from at least one external source within the vehicle, and a non-volatile memory formed on the semiconductor substrate and connected to the communications circuit for storing only once a predetermined identification code. The communications circuit writes the received data to the non-volatile memory as the predetermined identification code when the control circuit is within the vehicle if the predetermined identification code has not already been stored therein.
