MANAGING DEVICE, MEASURING DEVICE, SERVICE PROVIDING DEVICE, PROGRAM, TRANSMITTING SYSTEM AND TRANSMITTING METHOD

Document Type and Number:

WIPO Patent Application WO/2016/042664

Kind Code:

A1

Abstract:

A managing device according to an embodiment is connected via a first network to a measuring device installed for each user. The managing device is also connected via a second network to a service providing device managed by a service provider. The managing device includes a class creating unit, a first key creating unit, a class transmitting unit, and user secret information transmitting unit. The class creating unit uses a service-providing-device identifier, which is stored therein and shared with the service providing device, to create class information. The first key creating unit uses the class information and a measuring device individual key, which is stored therein and shared with the measuring device, to create a user key. The class transmitting unit transmits the created class information to the measuring device via the first network. The user secret information transmitting unit transmits the created user key to the service providing device via the second network.
