Title:
データ管理装置、電力使用量計算システム及びプログラム
Document Type and Number:
Japanese Patent JP5509366
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power usage amount calculation technology capable of calculating a total amount of power usage amounts while protecting privacy by concealing each power usage amount aggregated by each power meter in a meter data management device.SOLUTION: In a data management device, a power meter for aggregating power usage amounts of an electric apparatus and an application server are connected. The data management device comprises: a reception section for receiving a first cryptography message where the power usage amount aggregated by the power meter is encrypted so as to be decodable by the application server; a first calculation section for calculating a cryptography message of a first total amount of the power usage amounts within a prescribed period of time by using the first cryptography message; and a sending section for sending the cryptography message of the first total amount to the application server.
