Hereinafter, an identity and identity management service application using a blockchain according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the identity and identity management service application 100 using the blockchain according to the present invention authenticates the identity or account of the original and multi-use copyright holder, as well as the date of occurrence and contents. It is linked with the prototype web page 120 and the blockchain network 150 so that it can be done.

As an embodiment, the identity and identity management service system 100 using the blockchain of the present invention accesses the prototype webpage 120 from the terminal of the original copyright holder and the multi-use copyright holder who has transformed the original work, and uploads information related to the work. And it can be authenticated in the blockchain network 150.

At this time, the original copyright holder and the multi-use copyright holder access the prototype web page 120 through a wired/wireless communication network and upload a work file, and the uploaded file is distributed and stored among peers of the block chain network 150, and copyright to certify the occurrence of

Meanwhile, as shown in FIG. 2, the present invention includes an original account management unit 110, a prototype web page 120, a multi-use account management unit 130, a contract management unit 140, and a blockchain network 150 as an embodiment. do.

In this configuration, the present invention is implemented programmatically by being installed in a terminal device processed by a computer such as a server, and as shown in FIG. 3, the original account management step (S110), the work upload step (S120), and the multi-use account management step (S130), use contract management step (S140) and encryption step (S150).

Therefore, the original account management unit 110 and the multi-use account management unit 130 manage the accounts of the original copyright holder and the Nth copyright holder, respectively, and upload the work to the prototype web page 120 so that it can be started.

In addition, according to the contract management unit 140, it manages the copyright use contract between the original copyright holder and the Nth copyright holder as well as the screening of dynamic participation of global participating organizations, and the blockchain network 150 includes works, copyright holders' accounts, copyrights, Encrypt and distribute contracts and reviews.

To this end, in the original account management step (S110), the primary copyright account of the original copyright holder is received and managed through the original account management unit 110. can do.

In this case, the original copyright holder means the copyright holder for the original work among One Source Multi-Use (OSMU) works.

For example, the original work may typically be a webtoon file including an image file, and in comparison, a multi-use copyright holder may be a producer of a movie or drama that transforms a webtoon.

This original account management unit 110 may be implemented in a web server where the prototype web page 120 is built in a way that allows computational processing or may be implemented in a node (peer) constituting the blockchain network 150.

Next, in the work upload step (S120), through the prototype web page 120, content as a work and related information are registered. The uploaded original work and meta information of the original work are managed for each primary copyright account.

As an example, the prototype web page 120 is planned and designed as a UI/UX that can be conveniently used by original authors and second-level to multi-dimensional authors, and includes a main page, announcements, content registration management page, and content revenue status. contains the page

This prototype web page 120 may further include a database 121 for temporary storage of data, and the uploaded original work is finally encrypted and stored in the blockchain network 150 in a distributed manner.

In addition, through the prototype web page 120, works of multi-use copyright holders can also be uploaded, and if necessary, works can be provided to the general public in conjunction with a work providing service server.

For example, if the work is a webtoon, the registered content is individually processed along with the author's account information on the webtoon platform, and is processed so that each artist can register and manage multiple contents. In addition, when content registration is completed, readers can check whether the content has been published and view it through the app service.

In the multi-use account management step (S130), the multi-use account management unit 130 receives and manages the Nth copyright account of the multi-use copyright owner, which has transformed the original work into another form. As described above, a multi-use work may be a movie or drama that transforms a webtoon.

In addition, the multi-use account management unit 130 may also be implemented in a web server where the prototype web page 120 is built in a manner capable of computing processing, or implemented in one or more nodes constituting the blockchain network 150. .

Next, in the use contract management step (S140), the copyright use contract between the original copyright holder and the multi-use copyright holder is managed through the contract management unit 140. The content of the contract that permits secondary, tertiary or more transformation of the original copyright holder's work is recorded in a smart contract method.

To this end, the contract management unit 140 may call the primary copyright account of the original copyright holder and the Nth copyright account of the multi-use copyright holder, specify the parties, receive works and/or meta information, and include them in the contents of the contract.

In addition, the contract management unit 140 manages the review of dynamic participation of global participating organizations, stores related records during internal review according to the request for participation in the blockchain network 150 node, and provides new organizations and peers through the cloud. Dynamically generated programs can be provided.

Next, in the encryption step (S150), the information on the content, which is a work, is encrypted together with the copyright owner's account and stored in the blockchain network 150. In particular, it is recorded by assigning a hash value to the block file including the original work and the work meta information, and is based on a distributed P2P file system.

As shown in FIG. 4 , content-related information recorded in the blockchain network 150 includes a copyright owner's account, a copyright generation date, and various 'work meta-information' included in the content. The 'work meta information' may include the title of the content, readership, serial information, characters, and logline.

In addition, the distributed P2P file system distributes and stores data to a plurality of peers to enable large-capacity file storage, and each node constituting the blockchain network 150 can be applied as a peer.

At this time, a multi-use work modified from the original work by a multi-use copyright holder may also be recorded (distributed storage) in the blockchain network 150 .

As above, the present invention includes a file mapping step of performing interface access by the content management API 151 and location storage by the file matching unit 152 so that the work can be stored and recalled in the blockchain network 150 .

The content management API 151 corresponds to an interface that connects to the blockchain network 150 through the web (WEB) or WAP, specifies resources, and transmits commands. For example, Restful API (application programming interface ) is applied.

Therefore, the works uploaded through the prototype webpage 120 are recorded by accessing the blockchain network 150 through the content management API 151, and the file matching unit 152 is connected to the blockchain network 150. The location information of the recorded work is memorized and provided.

For example, when content is uploaded through the prototype web page 120 to register content of a webtoon artist, the original image of the registered content is converted into a PNG file, compressed, and uploaded. At the same time, the meta information of works such as the title, genre, target readership, serial information, characters, and logline of the content is also registered.

In addition, the content identification key generates, registers, and uses the hash (HASH) value of the uploaded content source file with the double sha256 algorithm, and the uploaded content source file is distributed by linking the content management API (151) of the Block Nova solution. It is stored in IPFS (InterPlanetary File System), a peer-to-peer file system.

In the case of distributed storage, the original work and the Nth work may be divided into unit files of a predetermined size and stored in a distributed manner. Such a distributed storage file is also called a chunk file according to a distributed system, and if necessary, a plurality of chunk files are copied and stored together.

By recording in which node the distributedly stored file is recorded on the blockchain network 150 in a look-up table method, etc., it can be recalled later as well as recorded in the blockchain.

At this time, by including a storage key for encryption and a content identification key in the block file, unauthorized persons or unauthorized users may not be allowed to access or download.

Meanwhile, as shown in FIGS. 5 and 6, the present invention provides dynamic participation and review management functions of global participating organizations. To this end, the contract management unit 140 manages dynamic organization (Org) and blockchain node (Peer) addition and channel join so that foreign affiliates can easily participate in the blockchain network (150).

In addition, new blockchain nodes can provide existing smart contracts and data, conduct internal screening when requested to participate in the blockchain network 150, and dynamically create new organizations and peers through the cloud.
