By using the IoT device sharing apparatus 1 and linking each function of the IoT device 2 that can be used as a shared resource, a new service that cannot be performed by a single device can be provided. At that time, even a company that does not have the IoT device 2 can provide a new service across the network.

  For example, as shown in FIG. 8B, as shared resources registered in the IoT device sharing apparatus 1, a camera of X company (sensor function), a display of Y company (actuator function), and an image of Z company Assume that an analysis engine (computing function) is registered. In this case, Company S uses these resources to detect human behavior with Company X's camera, analyzes it with Company Z's analysis engine, and displays the corresponding advertisement on Company Y's display. It becomes possible to provide such a new service even if the company S does not have resources.

[Effect 3] Reduction of unnecessary facilities through effective use of resources (see Fig. 8 (c))
By grasping each function of the IoT device 2 registered in the IoT device sharing apparatus 1 as an available surplus resource, existing facilities (resources) can be effectively used without adding a new device. That is, the user of the IoT service can reduce the number of devices required for enjoying the service.

For example, as shown in FIG. 8C, when the allowable processing amount of the resource of the X company is four times the reference processing amount (reference processing amount), the reference processing amount of 6 is provided as the service of the X company. When it is necessary to provide a service that doubles, the IoT device sharing device 1 is used and the resource of Company Y that can be used as a shared resource (twice the standard processing amount) is used as the surplus processing amount. It becomes possible.
As a specific example, it is assumed that company X provides an IoT service for analyzing a camera image and specifying a person. In the IoT service, if the camera is shooting a specific point, usually (weekdays), the number of people to be photographed, that is, the number of people to be photographed is small, but the number of people to be photographed suddenly increases on holidays etc. It is necessary to temporarily increase the processing capacity. In such a case, it is possible to cope with a sudden change by using the computing function located in the vicinity of the network cost by using the IoT device sharing apparatus 1.

[Effect 4] Generation of Incentives by Providing Resources A user who has provided the IoT device 2 (owner of the IoT device 2) can obtain a usage fee when the IoT device 2 is used by another user. Therefore, an incentive for providing resources can be generated.

[Effect 5] Prevention of misuse by IoT device users By registering and using each function (sensor function, computing function, actuator function) of the IoT device 2 in the resource management information 120 of the IoT device sharing apparatus 1, The user of the IoT device 2 does not directly control each function, but the IoT device sharing apparatus 1 mediates. This makes it possible to prevent abuse and ensure safety.
