Referring to FIG. 3, the method for providing online music scores with an authentication code within a consortium blockchain network for providing music scores is composed of the following steps. In step 301, the music score providing server 11 configures a consortium blockchain network for providing music score consisting of the music score providing server 11 and a plurality of nodes 12. The music score providing server 11 is a server that configures and manages a consortium blockchain network for providing music score, and verifies the node 12 participating in the consortium blockchain network for providing music score. Only the node 12 verified by the music score providing server 11 can participate as a member node of the consortium blockchain network for providing music score.

In this regard, FIG. 4 is a detailed flowchart of the steps of configuring the consortium block chain network for providing musical scores shown in FIG. 3 . Referring to FIG. 4, in step 3011, the music score providing server 11 transmits an information request signal requesting node verification information to the node 12 that intends to participate in the music score providing consortium blockchain network. The music score providing server 11 transmits a signal requesting information of the corresponding node 12 in order to verify a node that intends to participate in the music score providing consortium blockchain network.

In step 3012, the music score providing server 11 is based on the node verification information transmitted from the node in response to the information request signal, based on the node verification information of the node 12 trying to participate in the consortium blockchain network for providing music score Verify node 12. Upon receiving the information request signal from the sheet music providing server 11, the node 12 transmits a signal including node verification information to the sheet music providing server 11 in response to the information request signal. The node verification information includes an identifier of the node 12, a password associated with the identifier, user information of the node 12, an internet protocol (IP) of the node 12, and the like.

The verification module 1104 of the music score providing server 11 verifies the node 12 that intends to participate in the consortium blockchain network for providing music score based on the node verification information transmitted from the node 12. For example, the verification code 1104 of the music score providing server 11 stores the identifier and password associated with the identifier included in the node verification information stored in the storage 1103 of the music score providing server 11 and the password associated with the identifier. It is verified whether they match and/or whether the IP of the node 12 is included in the subscription IP list stored in the storage 1103 of the music score providing server 11.

In step 3013, the music score providing server 11 configures a consortium blockchain network for providing music score consisting of the music score providing server 11 and the verified node 12 based on the verification result. For example, the music score providing server 11 matches the identifier and password associated with the identifier included in the node verification information transmitted by the node 12 and the identifier stored in the storage 1103 and/or Alternatively, if the IP of the node 12 is an IP included in the subscription IP list stored in the storage 1103, the corresponding node 12 is involved as a member node of the consortium blockchain network for providing musical scores.

In step 302, the music score providing server 11 receives a request for providing music score from an arbitrary node 12 of the consortium blockchain network for providing music score. The sheet music providing server 11 receives a request for providing sheet music for a specific sheet music from any node 12 constituting the consortium blockchain network for providing sheet music, that is, the node 12 verified by the sheet music providing server 11. . A user of the node 12 may input a command requesting a score desired to be output through the node 12 . The node 12 transmits a sheet music providing request including a request for the input sheet music to the sheet music providing server 11 based on the user's input. The sheet music provision request includes sheet music specific information (eg, name of the sheet music, composer, release year, etc.) input by the user of the node 12, sheet music usage period, sheet music usage range (eg, performance venue, performance date, number of performances, recordings other than performances, broadcasting, etc.).

In step 303, the music score providing server 11 approves the music score provision request based on the node verification information of the node 12 and the music score provision request, and generates an authentication code associated with the music score included in the music score provision request. The music score providing server 11 determines whether to approve the music score provision request based on the node verification information transmitted from the node 12 and the music score provision request.

More specifically, the sheet music providing server 11 checks the sheet music access authority of the identifier included in the node verification information. The sheet music providing server 11 compares at least one sheet music included in the sheet music access list for each identifier stored in the storage 1103 with sheet music specific information included in the sheet music provision request, and the sheet music specific information included in the sheet music provision request indicates If the sheet music is included in the user's sheet music access list, it is determined that the sheet music access right exists. When it is determined that there is a music score access right, the music score providing server 11 approves the music score provision request of the node 12 .

For example, when user "A" of node 12 purchases sheet music "B", sheet music providing server 11 adds the sheet music access list of the identifier of user "A" to storage 1103. The storage 1103 of the music score providing server 11 stores a music score access list for each user's identifier. The storage 1103 stores a musical score access list for each user identifier, a musical score providing period, and a musical score providing range for each musical score.

When the sheet music providing server 11 approves the sheet music provision request of the node 12, that is, when the sheet music access list associated with the identifier of the node 12 includes the sheet music indicated by the sheet music specific information, it is included in the sheet music provision request. Generates an authentication code including authentication information for the recorded sheet music. The authentication code generation module 1105 of the sheet music providing server 11 generates an authentication code including information about sheet music specific information, a sheet music providing period, and a sheet music providing range of the sheet music provided by the user. Here, the authentication code is a code representing the authentication information of the score, and representative examples include a QR (Quick Response) code, a barcode, and the like.

In step 304, the sheet music provision server 11 transmits the sheet music included in the sheet music provision request and an associated authentication code to the node 12 that has transmitted the sheet music provision request. When the sheet music providing server 11 approves the request for providing the sheet music of the node 12, it transmits the determined sheet music and the authentication code associated with the sheet music generated in step 303 to the node 12 that has transmitted the request for providing the sheet music.

In step 305, the node 12 that has received the sheet music and the authentication code associated therewith from the sheet music providing server 11 generates a block including the sheet music and the associated authentication code, and uses the generated block as a consortium blockchain network for providing sheet music. distributed to The node 11 creates a block including the sheet music received from the sheet music providing server 11, a sheet music providing period, and a sheet music providing range. The node 12 distributes the created block to the consortium blockchain network for providing music scores including the node 12 and the music score providing server 11.

In this way, a specific node of the consortium blockchain network for providing musical scores receives a specific musical score, and distributes a block containing information such as the musical score providing period of the provided musical score and the range of musical scores provided to the consortium blockchain network for providing musical scores. By distributing the music score and the block containing the verification code associated with the score to the consortium blockchain network for providing music scores, it prevents third parties from arbitrarily modifying the score related verification code.

In step 306, the node 12 having received the sheet music and the authentication code associated therewith from the sheet music providing server 11 outputs the sheet music and the authentication code associated therewith. The node 12 may output the received sheet music and an authentication code associated therewith using an output device 21 connected to the node 12 . Here, a representative example of the output device 21 may include a printer. The user of the node 12 can check the sheet music and the authentication code output through the output device 21. For example, the node 12 may output the sheet music and the associated authentication code on paper through a connected print.

In this regard, FIG. 5 is a diagram showing an embodiment of the sheet music output in the step of outputting the sheet music shown in FIG. 3 . Referring to the example shown in FIG. 5 , a musical score displaying clefs, key signatures, time signatures, and musical notes is output, and an authentication code of the musical score is output together at the top left of the musical score.

As the authentication code is output together with the musical score, the user of the node 12 can check whether the musical score output through the authentication code is legitimate. More specifically, each of the plurality of nodes participating in the consortium blockchain network for providing musical scores can verify whether the musical score printed with the authentication code is a legitimate musical score by verifying the authentication code output together with the musical score.

The user of the node 12 may take an image representing the authentication code output on the sheet music. The user can use the camera module 1204 of the node 12 to take a picture of the authentication code included in the output sheet music. The camera module 1204 of the node 12 generates an authentication code image representing the authentication code included in the score.

The node 12 determines whether the sheet music printed with the authentication code is a legitimate sheet music based on the generated authentication code image. More specifically, the node 12 determines whether the same authentication code as the authentication code indicated by the authentication code image exists among the blocks distributed in the consortium blockchain network for providing musical scores. The node 12 compares the authentication code included in the blocks distributed in the consortium blockchain network for providing musical scores with the authentication code represented by the authentication code image.

As a result of the comparison, if the authentication code represented by the authentication code image matches the authentication code included in any one of the blocks distributed in the consortium blockchain network for providing musical scores, the node 12 determines the authentication code represented by the authentication code image. read The node 12 reads the sheet music specific information included in the authentication code, the sheet music use period, and the sheet music use range. If the sheet music usage period has not elapsed, the node 12 determines that the sheet music printed with the authentication code is a legitimate sheet music. Conversely, if the period of use of the sheet music included in the authentication code results, node 12 determines that the sheet music printed with the authentication code is an invalid sheet music.

As a result of the comparison, if the authentication code indicated by the authentication code image does not match the authentication code included in all of the blocks distributed in the consortium blockchain network for providing musical scores, the node 12 determines that the musical score printed with the authentication code is an illegal musical score. decide that

The node 12 performs authentication indicated by the authentication code included in the block and the authentication code image, based on whether or not the similarity between the authentication code included in the block and the authentication code represented by the authentication code image is equal to or greater than a threshold similarity preset by the designer. Determines whether the codes match.

More specifically, the similarity calculation module 1205 of the node 12 outputs a similarity between the authentication code included in the block and the authentication code represented by the authentication code image. The similarity calculation module 1205 of the node 12 is an artificial neural network trained to output a similarity between two images. The similarity calculation module 1205 outputs a similarity between the two authentication codes input to the similarity calculation module 1205 . The degree of similarity between two authentication codes is an index indicating the similarity between the authentication code represented by the authentication code image and the authentication code included in the block, and is expressed as a score between 0 and 100. The similarity calculation module 1205 outputs 100 points when both authentication codes completely match, and outputs 0 points when both authentication codes are completely different. In the similarity calculation module 1205 , the node 12 inputs the output similarity to the comparison module 1206 .

The comparison module 1206 of the node 12 compares the similarity input from the similarity calculation module 1205 with a threshold similarity, and if the similarity is greater than or equal to the threshold similarity, the authentication code indicated by the authentication code image matches the authentication code included in the block. If not, it is determined that the authentication code indicated by the authentication code image and the authentication code included in the block do not match.

Here, the threshold similarity is a criterion score for determining whether the authentication code included in the block and the authentication code represented by the authentication code image match. When the similarity calculated by the similarity calculation module 1205 is equal to or greater than the threshold similarity, it is determined that both authentication codes match, and when the calculated similarity is less than the threshold similarity, it is determined that both authentication codes do not match.

When the node 12 determines that the authentication code included in the block and the authentication code represented by the authentication code image match, it determines that the musical score including the authentication code is legitimate, and if not, it determines that the musical score including the authentication code is illegal. do.

Summarizing the above, a random node among the plurality of nodes participating in the consortium blockchain network for providing music scores displays the authentication code image representing the authentication code output along with the music score and the blocks distributed in the consortium blockchain network for providing music scores, respectively. Compares the authentication codes included in , and verifies the authentication code based on the comparison result. The node verifies whether the score printed with the verification code is a legitimate score by verifying the authentication code output together with the score.

According to an embodiment of the present invention, the threshold similarity may be set in advance by a designer or manager of the score providing server 11 . According to another embodiment of the present invention, the threshold similarity may be set to be proportional to the resolution of the camera module 1204 of the node 12 that captures the authentication code printed along with the score. For example, when the resolution of the camera module 1204 of the node 12 is high, the threshold similarity is set high, and when the resolution of the camera module 1204 of the node 12 is low, the threshold similarity is set low. Accordingly, by varying the threshold similarity according to the resolution of the camera module 1204 of the user's node 12, the accuracy of determining the degree of similarity between the authentication code printed with the score and the authentication code stored in the block can be improved.

According to the above-described embodiments of the present invention, the method for providing online music scores having an authentication code within the consortium blockchain network for providing music scores involves only nodes verified by the music score providing server participating in the consortium blockchain network for providing music scores, Only nodes participating in the consortium blockchain network for providing musical scores provide musical scores. Accordingly, it is possible to prevent nodes and users who do not have access rights to the musical score from accessing the musical score.

In addition, according to the embodiments of the present invention, when the music score providing server provides the score to the node within the consortium blockchain network for providing the score, the score providing server provides the authentication code associated with the score to the node, and to the node. A block containing the provided sheet music and authentication code is created and distributed to the consortium blockchain network for providing sheet music. As described above, by distributing a block indicating that a specific node has been provided with a specific sheet music to the consortium blockchain network for providing sheet music, it is possible to prevent hacking of access rights to the sheet music by nodes and users who do not have access to the sheet music, Security can be improved.

Additionally, according to embodiments of the present invention, when a node outputs a score, it also outputs an authentication code associated with the score. Using the output authentication code, it is possible to check whether the sheet music being used is a legitimate sheet music purchased from a sheet music seller. The node can compare the authentication code image representing the authentication code printed on the sheet music with the authentication code included in the block distributed on the blockchain network of the consortium for providing sheet music to confirm whether the sheet music is legitimate. Accordingly, it is possible to quickly and accurately determine whether the sheet music being used is a legitimate sheet music.
