  • Electronic apparatus, electronic apparatus operation system, authentication system, authentication method, and information storage medium
    Patent number: 6736312
    Abstract: A system controller reads first identification information from a semiconductor storage medium. The system controller causes an audio block to operate when a portion of the first identification information coincides with one of a whole and a portion of the second identification information stored in a non-volatile memory. The system controller stores another portion of the first identification information as a portion of the second identification information in the non-volatile memory. Even if a user adds the first identification information to the semiconductor storage medium, an onboard audio apparatus reads and stores an additional portion of the first identification information in the non-volatile memory. The first identification information added by the user is used for a next operation enable/disable determination for the audio block.
