Description

[Technical Field]

[0001] The present disclosure relates to a home system, a server, an owner authentication method, and an owner authentication program. [Background technology]

[0002] The number of home appliances that can be connected to the Internet is increasing. Smart home systems that utilize home appliances connected to the Internet to provide residents with comfortable and convenient functions have been proposed. For example, smart locks that can remotely lock and unlock front doors using smartphones have been introduced as part of smart home systems.

[0003] When the resident of a house where a smart home system is installed changes, the users who can use the smart home system must be changed from the previous resident to the new resident. Unless the registration of users who can use the smart home system (hereinafter also referred to as "user registration") is changed appropriately, it is difficult to ensure the security of the smart home system.

[0004] A method has been proposed to ensure the security of a smart home system when the resident of a house in which the smart home system is installed changes. For example, the apartment building system described in Patent Document 1 deletes personal information stored in the residential terminal when a resident moves out.

[0053] The smart home application AP can register or change the setting information of the control device 2 by communicating with the control device 2 via the network NW or by communicating with the control device 2 by short-range wireless communication WC2.

[0054] [Server 7] The server 7 is configured, for example, by one or more servers and can be connected to a network NW. The server includes hardware such as a processor such as a CPU, memory, recording media such as a hard disk or flash memory, and a communication device. The functions of the server 7 are realized by a program executed in the server's processor. The server may be an on-site server, or a cloud server that provides IaaS (Infrastructure as a Service), PaaS (Platform as a Service), SaaS (Software as a Service), or the like, or a server that combines these. In the following description, "server" includes any of the above servers.

[0055] The server 7 includes a device management server 8 and a user management server 9. The device management server 8 and the user management server 9 may be the same server.

[0056] [Device Management Server 8] The device management server 8 is a server that manages the household equipment 1. The device management server 8 acquires control instructions for the household equipment 1 that are generated in the smart home application AP. The control instructions for the household equipment 1 are acquired by the household equipment 1.

[0057] The device management server 8 acquires the status of the household equipment 1 based on a user request. The status of the household equipment 1 is acquired by the smart home application AP.

[0058] [User Management Server 9] The user management server 9 is configured by, for example, one or more servers, and is connectable to a network NW. The functions of the user management server 9 are realized by a program executed in a processor of the server.

[0059] The user management server 9 is a server that manages the registration of users who can use the home system 100 (hereinafter also referred to as "user registration"). The user management server 9 assigns a user code to a registered user. The user code is a code that is unique in the home system 100 and is a code that identifies a user in the home system 100. The user code is, for example, a user ID.

[0060] User registration is information that is recorded by associating a user code that identifies a user with the household equipment 1 that the user can use. User registration may be recorded collectively for multiple household equipment 1 installed in a home HO, or may be recorded separately for each household equipment 1. A registered user can use the associated household equipment 1.

[0061] A user of the home system 100 can obtain a user code from the user management server 9. The user code obtained by the user is registered in the smart home application AP of the smartphone 6. The user code is also recorded in the device management server 8. A control instruction for a household equipment 1 generated by the user in the smart home application AP is obtained by the device management server 8 and the household equipment 1, which are associated based on the user code.

[0062] Next, a description will be given of the operation of the home system 100. Hereinafter, the operation of the home system 100 will be described with reference to a sequence diagram of the home system 100 shown in FIG.

[0063] In step S100, the server 7 detects a change in the owner of the home HO. For example, the server 7 determines that the Internet provider ISP of the home HO has changed by detecting a change in the global IP address of any of the communication paths with the home equipment 1 (such as the access point 4, the control device 2, or the home equipment 1 to which a global IP address has been assigned). The server 7 detects a change in the owner of the home HO by determining that the Internet provider ISP of the home HO has changed. Note that the method for detecting a change in the owner of the home HO is not limited to this, and other detection methods may also be used.

[0064] In step S110, the server 7 requests the smartphone 6 to search for the household equipment 1 connected to the facility network. The smartphone 6 requested to be searched by the server 7 is the smartphone 6 of a user who has registered with the household equipment 1 of the home HO. The server 7 may also request the smartphone 6 to search for the control device 2 and the access point 4 connected to the facility network.

[0065] In step S120, the smart home application AP of the smartphone 6 searches for household equipment 1 connected to the facility network.

[0066] The household equipment 1 that can communicate with the smartphone 6 via the facility network responds to the smartphone 6 in step S130.

[0067] In step S140, the smart home application AP of the smartphone 6 reports the detection of the household equipment 1 to the server 7.

[0068] In step S150, the server 7 determines whether the smartphone 6 is located in the home HO. Specifically, if the household equipment 1 detected by the smart home application AP of the smartphone 6 is installed in the home HO, the server 7 determines that the smartphone 6 is located in the home HO. This is to indicate that the smartphone 6 is connected to the facility network of the home HO and has communicated with the household equipment 1.

[0069] In step S160, the server 7 authenticates that the user registered in the smart home application AP of the smartphone 6 is the new owner who has moved into the house HO (owner authentication).

[0070] In step S170, the server 7 registers the user (new owner) registered in the smart home application AP of the smartphone 6 as a user who can use the home system 100, and permits the new owner to use the home system 100.

[0071] If the smart home application AP of the smartphone 6 cannot detect the household equipment 1, or if the household equipment 1 detected by the smart home application AP of the smartphone 6 is not installed in the home HO, the server 7 determines that the user registered in the smart home application AP of the smartphone 6 is the previous owner of the home HO. The server 7 invalidates the registration of the user who could use the household equipment 1. The previous owner of the home HO who was registered as a user will no longer be able to use the household equipment 1.

[0072] Next, another operation of the home system 100 will be described with reference to a sequence diagram of the home system 100 shown in FIG.

[0073] In step S200, the server 7 detects a change in the owner of the residence HO, similarly to step S100.

[0074] In step S210, the server 7 transmits to the smartphone 6 an operation instruction for the household equipment 1. The smartphone 6 requested to be searched by the server 7 is the smartphone 6 of a user who has been registered as a user for the household equipment 1 of the home HO.

[0075] At this time, it is desirable that the server 7 disables remote control instructions to the household equipment 1 from the smart home application AP of the smartphone 6.

[0076] In step S220, the smart home application AP of the smartphone 6 notifies the user of an operation instruction for the household equipment 1 by displaying it on the touch panel 63, for example.

[0077] The user performs operations in accordance with the operation instructions for the household equipment 1. For example, the operation instructions for the household equipment 1 include "open and close the door on which the opening / closing sensor 1A is installed twice," "lock and unlock the electric lock 1B twice," "open and close the electric shutter 1C twice," "change the settings of the camera 1D," and "change the set temperature of the air conditioner 1E to 25 degrees." The operation instructions for the household equipment 1 relate to operations that cannot be performed unless the user of the smartphone 6 is at the house HO.

[0078] In step S230, the dedicated remote controller 3 operates the household equipment 1 from a short distance based on the operation input by the user.

[0079] The server 7 acquires the change in the state of the household equipment 1 in step S240.

[0080] In step S250, the server 7 determines that the smartphone 6 is in the home HO if the state of the household equipment 1 has changed in accordance with the operation instructions for the household equipment 1. This is because if the user of the smartphone 6 is not in the home HO, the household equipment 1 cannot be operated from a short distance by operating the dedicated remote control 3 or the smartphone 6.

[0081] In step S260, the server 7 authenticates that the user registered in the smart home application AP of the smartphone 6 is the new owner who has moved into the house HO (owner authentication).

[0082] In step S270, the server 7 registers the user (new owner) registered in the smart home application AP of the smartphone 6 as a user who can use the home system 100, and permits the new owner to use the home system 100.

[0083] If the state of the household equipment 1 has not changed in accordance with the operation instructions for the household equipment 1, the server 7 determines that the user registered in the smart home application AP of the smartphone 6 is the previous owner of the home HO. The server 7 invalidates the registration of the user who could use the household equipment 1. The previous owner of the home HO who was registered as a user will no longer be able to use the household equipment 1.

[0084] According to the home system 100 of this embodiment, a new resident of a house can easily and safely start using the home system 100 as a user. The user authenticated as the new owner may be any resident residing in the house HO, and may also be a group of multiple people, such as a family. When a group of multiple people is registered as users, all registered users may be authenticated as the owner, or an arbitrarily set user may be authenticated as the owner.
