DATA MANAGEMENT DEVICE, POWER CONSUMPTION AMOUNT CALCULATION SYSTEM AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a power consumption amount calculation technology capable of calculating a total amount of power consumption while protecting privacy by shielding the power consumption amount tallied by each power meter with a meter data management device.

SOLUTION: A data management device which is connected to a power meter tallying a power consumption amount of electric equipment and an application server comprises: a reception section to receive a first code message where the power consumption amount tallied by the power meter is encrypted so as to be decodable by the application server; a first calculation section to calculate a code message of a first total amount of the power consumption amount within a prescribed period of time using the first code message; and a sending section to send the code message of the first total amount to the application server.
