The service company terminal unit 40, which has received the smart device service request information, uses the smart device authentication key included in the smart device service request information to use the usage history information (state) distributed and stored by the smart device 30 in the blockchain network. information) and begins monitoring for abnormalities in the smart device 30 (S117).

On the other hand, the smart device 30 measures its own operating state periodically or each time it operates (S119), and generates usage history information including status information about the measured operating state and the smart device authentication key (S121). , distributed storage begins on the blockchain network (10) (S123).

When the smart device 30 begins to distribute and store usage history information on the blockchain network 10, the owner terminal 20 and the service provider terminal 40 use the smart device authentication key of the smart device 30. You will be able to check the status of the smart device 30 by checking the usage history information (S125, S127).

When monitoring of the smart device 30 begins, the service provider terminal 40 checks whether a service event occurs (S128). The service event may be generated when there is a problem with the smart device 30 by analyzing the status information of the usage history information, or it may be generated by a service company employee's command to inspect the smart device 30.

When a service provision event occurs, the service provider terminal 40 displays status information based on usage history information (S129).

When the status information is displayed, the service provider terminal 40 checks whether a service provision event has occurred (S130). The service provision event may be generated by a service company employee when a remote management service is provided to the smart device 30 in which the abnormality has occurred. After the service provision event, the service provider terminal unit 40 receives service provision information according to service provision from the service company employee and provides service details information including service provision information, service provider terminal authentication key, and smart device authentication key. After creation (S131), it is distributed and stored in the blockchain network (10) (S133).

After receiving the service, the owner of the owner terminal 20 checks the service history information from the blockchain network 10 through the owner terminal 20 and visually confirms it, then provides verification information (evaluation information, etc.) according to service provision. Enter and save it in the blockchain network (10). The verification information may include verification details, smart device authentication key, service provider terminal authentication key, etc.

The remote management unit 50 periodically checks the service history information for the service assigned to the service company terminal unit 40, checks whether verification information exists accordingly, and, if the service history information and verification information exist, service details After verifying the information and verification information, the contract is implemented when the verification is successful (S137, S139).

Meanwhile, it is common knowledge in the technical field that the present invention is not limited to the above-described typical preferred embodiments, but can be implemented by various improvements, changes, substitutions, or additions without departing from the gist of the present invention. Anyone who has will be able to understand it easily. If the implementation by such improvement, change, substitution or addition falls within the scope of the appended patent claims below, the technical idea thereof should also be regarded as belonging to the present invention.
