An external mass storage device is secured against unauthorized access. The ECU modifies, in the case where the revolution speed of the engine is not controlled by the motor generator, the ignition timing for startup of the engine to a further timing advancing side, as compared to the case where the revolution speed of the engine is controlled by the motor generator. Then, an organic layer is formed on the entire surface of the transparent electrode layer and the insulating layer. The databases allow the verification engine to access the user’s personal information only through predefined queries.
