a display unit,
wherein the storage unit includes a United Extensible Firmware Interface (UEFI) Chip that contains a program for providing functions of a UEFI,
the storage unit stores firmware to be started before the operating system is started, and
the CPU stores in the storage unit a history of information input by users during activation of the firmware after the operating system is shut down and before the operating system is restarted, compares the history at the moment of shut down stored in the storage unit with the history at the moment of start of the operating system, and, when variation between the recorded contents of the respective histories exceeds a predetermined threshold value, displays information indicating presence of an unauthorized use on the display unit.
