ELECTRONIC APPLIANCE, POWER MANAGEMENT APPARATUS, AND METHOD OF IDENTIFYING APPLIANCE

摘要

PROBLEM TO BE SOLVED: To provide an electronic appliance configured such that it can more reliably detect tampering. SOLUTION: The electronic appliance includes: multiple electrical components having electrical characteristics different at every electronic appliance; a characteristics measuring unit that measures the characteristics of each electrical component; a switch that switches the electrical components whose characteristics are to be measured by the characteristics measuring unit; and a control unit that controls the switch and causes the characteristics measuring unit to measure the characteristics of a predetermined electrical component and transmits, to a power management apparatus managing at least power supply to its own electronic appliance, information relating to the characteristics measured by the characteristics measuring unit and the appliance ID of its own electronic appliance.
