1 is a diagram for explaining a service use system through a token issued on a blockchain network according to an embodiment of the present invention.

Referring to FIG. 1, the system for using a service through a token issued on a blockchain network of the present invention includes a first user terminal 100, a second user terminal 400, a service providing server 200, and a service access server 300. ) may be included.

The first user terminal 100 may access the service providing server 200, provide a service token issuance request, and receive a service token issued on the blockchain network 500 by the service providing server 200. The transmitted service token may be stored in a wallet application running on the first user terminal 100 . The user terminal 100 may include, for example, a computing device such as a smart phone, a personal computer (PC), a tablet PC, or a hardware wallet.

The first user terminal 100 may store and transmit the issued service token using the blockchain network 500 . The first user terminal 100 may perform user authentication and receive a service from the service server 1000 by providing a service token to the service server 1000 .

In addition, the first user terminal 100 may allow the second user terminal 400 to receive a service from the service server 1000 by transmitting the corresponding service token to the second user terminal 400 of another user.

That is, in the service use system through the service token issued on the blockchain network according to the embodiment of the present invention, any user who has the service token issued from the service providing server 200 can use the service token through the user terminal. User authentication is performed by providing the data to the access server 300, and the service can be provided from the service server 1000.

In addition, the first user terminal 100 may execute an application for using a service operated by the service server 1000 . For example, when the service provided by the service server 1000 is an OTT (Over the top) media service, the first user terminal 100 accesses the corresponding service and can reproduce an image provided from the service server 1000. You can run your application. Alternatively, when the service provided from the service server 1000 is a video conference service, the first user terminal 100 may access the corresponding service and execute a service application capable of conducting a video conference with at least one other user terminal.

Here, the wallet application and the service application running in the first user terminal 100 may be linked. For example, when the first user terminal 100 attempts to access a service through a service application, the service application connects to the URL address included in the service token, provides a service request, and causes the wallet application to access the stored service. A token may be requested to be transmitted to the service access server 300 . Of course, the first user terminal 100 may perform service use and storage/transmission of a service token by executing a single application.

Alternatively, when the first user terminal 100 receives a service token from another user terminal, the wallet application running in the first user terminal 100 stores the transmitted service token and provides the service included in the corresponding service token. Execution of an available service application may be requested, or a link through which a service application may be downloaded may be generated and output to the first user terminal 100 .

Like the first user terminal 100 , the second user terminal 400 may include a computing device capable of receiving services by accessing the service server 1000 through a service token. As described below, the second user terminal 400 may receive a service token from the first user terminal 100 and provide the service token to the service server 1000 to receive a service.

The service server 1000 may issue and distribute service tokens as user authentication means on the blockchain network 500 to users, and provide services to user terminals that have provided the service tokens. The service server 1000 may include a service providing server 200 and a service access server 300 . However, the configuration of the service server 1000 is not limited to this example, and a series of processes may be performed in one server unit, from issuance of a service token, user authentication using the service token, and service provision.

The service providing server 200 may issue a service token on the blockchain network 500 at the user's request and transmit the service token to the user terminal that provided the request.

The service token generated by the service providing server 200 may include a URL (Uniform Resource Locator) address that can be accessed to receive a corresponding service, access authority, and access conditions.

For example, when the service provided by the service server 1000 is an Over the top (OTT) media service, the service token generated by the service providing server 200 includes a URL address that can be accessed to use the OTT service, It may include a service level accessible by using the corresponding service token or a list of works to be serviced, a period of use for using the corresponding service token, and the like.

Alternatively, if the service provided by the service server 1000 is a video conference service, the service token generated by the service providing server 200 uses the URL address of a host that can be accessed to conduct a video conference and the corresponding service token. It may include the number of participants who can participate and the holding time of a video conference that can participate using the corresponding service token.

However, the service token may not include the personal information of the user using the corresponding service. That is, user authentication performed in the process of using a service may be performed based on whether or not the user provides a valid service token to the service server 1000, not based on provided personal information. Therefore, even if the service token is stolen by hacking the wallet application that stores the service token, personal information of the user holding the service token may not be leaked through the service token.

In addition, the issuance record of the service token issued from the service providing server 200 may be stored as blockchain data of the blockchain network 500 . The service token issuance date, issue quantity, and issuance history from the service providing server 200 may be distributed and stored in a plurality of nodes of the blockchain network 500 in the form of blockchain data.

The service providing server 200 may provide the service to the service access server 300 based on the authentication result provided from the service access server 300 . For example, when the service provided by the service server 1000 is an OTT service, the service providing server 200 may provide the user terminal with video data requested by the user through the service access server 300 .

The service access server 300 may receive a service token from a user who wants to access a service, and perform an authentication process using the service token. The authentication performed by the service access server 300 is, for example, whether the corresponding service token is a service token issued from the service providing server 200 or not, and the service request provided from the user terminal uses the access authority included in the corresponding service token. It may be based on whether access is possible and whether the service request provided from the user terminal is included in the validity period included in the corresponding service token.

Also, in some embodiments, the service access server 300 may perform authentication based on whether the user terminal that provided the service token has validly acquired the corresponding service token. For example, it is assumed that a service token is provided to the service access server 300 along with a service request from the second user terminal 400 . The service access server 300 may perform user authentication through validity of the service token, access authority, and access conditions.

The service access server 300 may verify the validity of the service token provided from the user terminal using blockchain data of the blockchain network 500 .

Validation of the service token may be performed by checking the issuance date, issuance quantity, and issuance history of the service token provided from the user terminal through blockchain data of the blockchain network 500 .

In addition, when the service access server 300 receives the service token from the second user terminal 400, it checks whether the service token has been effectively transmitted from the first user terminal 100 to the second user terminal 400. can

That is, a transaction record in which a service token is transmitted from the first user terminal 100 to the second user terminal 400 is checked on the blockchain network 500, and the service provided by the second user terminal 400 is checked. It is to check whether it is a user who owns the rightful right of the token.

Accordingly, when the service access server 300 receives a service token from a user terminal, it checks blockchain data related to the corresponding service token for user authentication. At this time, whether the user terminal (for example, the second user terminal 400) that provided the service token is a user terminal that received the service token after the first issuance from the service providing server 200, and if not, the second user terminal It can be verified through transaction data whether 400 has validly received the issued service token.

Through this, when the service token is leaked due to hacking of the first user terminal 100 or the like, security can be improved by preventing a user who does not have legitimate rights from accessing the service server 1000 and receiving a service. .

The blockchain network 500 may include a network formed by connecting nodes composed of a plurality of computing devices to each other. A plurality of nodes constituting the blockchain network 500 may generate and store blockchain data to store service token generation and transmission details.
