    Abstract: An information management system includes: an attribute information DB that stores attribute information of a user as user information; a data obtainer that obtains, from at least one home appliance used by the user, first device data including an operating status of the at least one home appliance; and an updater that updates the user information stored in the attribute information DB, using first attribute information that is based on the first device data obtained. The updater compares the first attribute information and second attribute information stored in the attribute information DB as the user information to determine whether a difference is present between the first attribute information and the second attribute information, and updates the user information with the first attribute information when determining that the difference is present, and does not update the user information when determining that no difference is present.

    IPC: H04L29/08

    Abstract: A device management system includes: a server; base stations for long-distance wireless communication; and a device that communicatively connect to one of the base stations and that each sequentially transmit, to the server via the one base station, operation information indicating the current operation state of the device. Upon sequentially receiving the operation information, each of the base stations sequentially transmits, to the server, unique information unique to the base station together with the sequentially received operation information. The server sequentially receives, and sequentially stores in association with each other, the operation information and the unique information. When first and second unique information received at first and second times, respectively, are different, the server separately manages first operation information received in a first period ending at the first time and second operation information received in a second period starting at the second time.

    IPC: H04L9/08

    CPC classification number: H04L9/0841

    Abstract: The information processing method according to the present disclosure is for a device, and allows for sharing, between a home-appliance main microcontroller (13) and a communication module (11), a shared key that is an encryption key of a common-key cryptosystem for protecting a communication path (12) between the home-appliance main microcontroller (13) and the communication module (11). The information processing method includes: holding, by the home-appliance main microcontroller (13), a first shared key; detecting, by the communication module (11), a mismatch between a first message authentication code added to encrypted data obtained from the home-appliance main microcontroller (13) through the communication path and a second message authentication code calculated from the encrypted data; and when the mismatch is detected in the detecting, sharing the first shared key between the home-appliance main microcontroller (13) and the communication module (11) by the communication module (11) obtaining the first shared key from the home-appliance main microcontroller (13).

    Abstract: An information management device includes: an obtainer that obtains first company information and personal information from a first company, the first company information relating to a first product or service of the first company, the personal information relating to a user who has purchased the first product or who has been provided with the service; a company information storage that stores the first company information obtained; a personal information storage that stores the personal information obtained; an integrator that integrates the company information and the personal information based on a purchase record or a use record to generate integrated information, the purchase record indicating that the user has purchased the first product, the use record indicating that the user has used the service; and a manager that manages an output of the integrated information based on restriction information for restricting an output destination of the integrated information.
