NOVELTY - The server (34) has a verifying unit (3009) analyzing data acquired from a local power management system composed of an electronic appliance provided with a sensor and a power management apparatus managing power supply to the electronic appliance connected to a power network by using history information of the system. Another verifying unit (3011) analyzes the data acquired from the system by using estimated value calculated by simulation using characteristics information and/or specification information of the electronic appliance. A control unit controls the verifying units.    USE - Analysis server i.e. security check server, for use with a power management apparatus to manage power supply of an electronic appliance. Uses include but are not limited to an electric vehicle i.e. electric car, plug-in hybrid electric vehicle, home appliance e.g. refrigerator and washing machine, personal computer, telephone, video appliance e.g. TV set and recorder, rechargeable cell e.g. lithium-ion and network attached storage (NAS), fuel cell, natural gas power generating apparatus, biomass power generating apparatus, photovoltaic apparatus, wind power generating apparatus and geothermal power generating apparatus.    ADVANTAGE - The server provides stable power supply from power generation facilities outside control of power companies. The power management apparatus provides high level security, so that the server detects attack to the local power management system from outside or illegal behavior performed within the local power management system and protects against attack in swift manner. The server enables a display unit to display authentication state of the appliances connected to the power management apparatus, so that a user can easily distinguish the authenticated appliance, thus increasing user maintenance efficiency. The server prevents lifestyle pattern of the user from being discovered by a third party. The server carries out complex management and control of power management apparatus in a safe and efficient manner. The server controls power, reduces power consumption and reduces carbon dioxide (CO2) emission.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for analyzing data.
