1 is a conceptual diagram showing a content distribution system 1 according to an embodiment. In one embodiment, the content distribution system 1 includes a content management system 100, a creator account 10 and a consumer account 20 using the same, and an electronic money exchange that can trade electronic money used in the content distribution system. It can be composed of (30).

The creator account 10 is an account used by creators who create new content. Here, the creator includes the author or secondary author under the copyright law. In one embodiment, the creator may be anyone who creates an account as a creator and registers content in the content management system, regardless of whether he or she is an actual creator or inventor protected by copyright law or other intellectual property law.

The creator account 10 can be used by registering in the content management system 100. The creator may directly input information necessary to create the creator account 10 into the content management system 100, or may reuse information previously registered in another system.

The consumer account 20 is an account used by a consumer (user) who uses the content registered in the content management system 100. The use of contents refers to all methods of utilizing certain information of contents registered in the contents management system. For example, the use of content is to view content information registered in the content management system (including detailed information such as summary and analysis of the content), or download part or all of the data of the content registered in the content management system. It can be something to receive.

The content management system 100 performs a management process for a creator and a consumer to distribute content. According to a matter to be described later, the creator registers the content in the content management system 100, and the consumer may receive information and data on the content through the content management system 100. The content management system 100 records all content distribution paths from the creator to the consumer in the blockchain, so that the amount paid by the consumer for the content is transparent to the creator and other equity holders who have a stake in the revenue for the content. Can be distributed.

In an embodiment, a consumer may pay for the use of the content by using electronic money to use the content. Payment details of electronic money may be recorded in the blockchain through the content management system 100. Consumers can directly purchase electronic money to use the content from the content management system. Alternatively, the consumer may purchase electronic money required to use the content through the electronic money exchange 30.

Hereinafter, the content management system 100 will be described with reference to FIG. 2. 2 is a block diagram of a content management system 100 according to an exemplary embodiment. The content management system consists of a contract management sub-system 110, a blockchain sub-system 120, and a data storage 130. Here, the expression of each sub-system is an exemplary expression describing that each sub-system is a system constituting a content management system, and the technical idea of the present invention is not limited to the expression of a content management system and its sub-system. For example, in one embodiment, the content management system 100 is composed of each sub-system 110, 120, 130 as described in FIG. 2, and each sub-system is composed of respective devices constituting it. Can be. Meanwhile, in another embodiment, the content management system may be composed of a content management device such as a server, and in this case, the content management device includes modules such as a plurality of processors, memory, data storage, input/output devices, and communication modules constituting the same. Can be configured.

The contract management sub-system 110 performs a process related to a smart contract. In one embodiment, the contract management sub-system 110 creates a smart contract for the creator and records it in the blockchain. When a creator registers a new content, the contract management sub-system 110 may receive an input from the creator of an item required for consumers to use the content and record it in the blockchain as a smart contract. The contract management sub-system 110 proceeds with a predetermined process according to the contents of the smart contract when consumers comply with the smart contract described by the creator.

For example, when registering content, a creator can write a smart contract by writing 100 won as the streaming cost of the content. A consumer who wants to stream the content may pay 100 won to the contract management sub-system 110 according to the smart contract. The contract management sub-system can provide streaming of the content to the consumer terminal after confirming that the consumer pays 100 won.

The contents of the smart contract created by the contract management sub-system 110 and histories according to its execution are recorded in the blockchain by the blockchain sub-system 120. The blockchain sub-system 120 may be a blockchain platform such as Ethereum.

The blockchain sub-system 120 records data requested by an external terminal such as the contract management sub-system 110 in the blockchain, and reads and provides the data recorded in the blockchain according to the request of the external terminal.

The blockchain sub-system 120 may record information on content in a blockchain. When a creator registers a new content in the content management system 100, the blockchain sub-system 120 records the creator information for the new content, the content of the smart contract created by the creator, and the content data in the blockchain. can do. The content data is data for using the content in a conventional manner. For example, when the corresponding content is video or audio, the content data is video or audio data for reproducing it.

When the size of the content data is large, the blockchain sub-system 120 does not record the entire content data in a blockchain, but records the content data in a separate data storage 130, and then stores the recording location for the data storage in a blockchain. Can be recorded.

In one embodiment, the data storage 130 may be an external data server, a cloud, or a storage of a personal PC. The recording location for the data storage 130 may be an access address for the storage, and may be an access code or access file required for P2P transmission.

In one embodiment, the data storage 130 may be a plurality of personal storages using a P2P-based file transfer service, and in this case, a file location for receiving a file using a P2P-based file transfer service is recorded as a recording location. A dedicated file for a P2P-based file transfer service or such record information can be recorded in a blockchain.

In another embodiment, the data storage 130 may be a plurality of personal storages using BitTorrent, and in this case, a magnetic file for receiving a file using BitTorrent as a recording location or such recording information is stored in a blockchain. Can be recorded.

The blockchain sub-system 120 may record information on smart contracts in a blockchain. As described above, the blockchain sub-system 120 may record a smart contract created by the contract management sub-system 110 in a relationship between a creator, a consumer, and other related entities in a blockchain.

The blockchain sub-system 120 may record the usage history of the content in a blockchain. In an embodiment, the block chain sub-system 120 may record a history of providing information on the content recorded in the block chain by the first terminal to the second terminal in a block chain. Alternatively, the blockchain sub-system 120 blocks the history of the first terminal providing the data of the content recorded in the blockchain to the second terminal and allowing the second terminal to play or use the corresponding content. Can be recorded with a chain. Alternatively, the blockchain sub-system 120 blocks the history of the price that the second terminal provided to the content management system 100 in order to use the content and the history of distribution of the price to the beneficiaries of the content. Can be recorded with a chain.

Hereinafter, a basic operation of the content management system according to an embodiment will be described with reference to FIG. 3. 3 is a flowchart illustrating an operation of a content management system according to an exemplary embodiment.

First, when the creator account 10 requests the content to be registered in the content management system 100, the content management system 100 records the new content in the blockchain (S310). When registering new content, the content management system 100 records the smart contract created by the creator for the corresponding content and data of the content in the blockchain. As described above, a recording location in a separate storage may be stored as content data.

Next, when the consumer account 20 makes a request to use the content recorded in the block chain, the content management system 100 provides the content according to the request for use (S320). In order for the consumer account 20 to use the content, all smart contracts required to use the content must be executed. For example, in order to enable consumers to use the content, the content management system 100 must transmit the content to the consumer terminal registered in the consumer account 20 and give the consumer account 20 permission to use the content. do. To this end, the content management system 100 transmits the items of the smart contract required for the use of the corresponding content to the consumer account 20, determines the information received from the consumer account 20, and then If all of the requirements are satisfied, the content by the smart contract is executed so that the consumer can use the content.

For example, in the smart contract required to use video content A, a consumer account with a first contract pays a copyright fee C1 to the copyright holder of the video content A, and a consumer account 20 with a second contract In order to receive the video content A, to download the data of the video content A through BitTorrent, C2 may be paid as a data transmission fee to the BitTorrent relay server and peer accounts that provided the torrent data piece of the data file. The consumer account 20 may transmit a price including data transmission charges C1 and C2 to the content management system 100 in order to use the video content A. The content management system 100 may confirm that the corresponding amount is deposited from the consumer account 20 and transmit the bittorrent access file to the consumer account 10 so that the content A can be used through bittorrent.

In an embodiment, data of content A may be encrypted with DRM. The content management system 100 verifies that the payment is received from the consumer account 20 and transmits the BitTorrent access file to the consumer account 20 so that the content A can be used through BitTorrent. It is also possible to transmit a possible decoding code.

Next, the content management system 100 records the history of content use in the blockchain (S330). As described above, the content management system 100 records a history of content-related information provided to an external consumer, a history of providing data for using content to a consumer, and information about the price provided by the consumer in a blockchain. .

Next, the content management system 100 allocates the content usage fee (S340). The content usage fee is an amount paid by the consumer account 20 to the content management system 100 according to the smart contract. The content management system 100 executes a smart contract created for each content, and distributes the usage amount to the beneficiaries of the content. For example, the allocation of the usage amount may be the deposit of a fixed currency into the bank account of each beneficiary stakeholder. Alternatively, the allocation of the usage amount may be the transmission of the electronic money determined to the electronic money account of each beneficiary stakeholder according to the amount allocated.

Finally, the content management system 100 records the distribution of the usage price in a block chain (S350).

Hereinafter, an embodiment of distributing content using the content management system 100 will be described through a flow chart. First, an embodiment in which the content registered by the creator terminal 420 is directly distributed to the consumer terminal 440 through the content management system 410 will be described with reference to FIG. 4.

Content registration and smart contract creation

The creator terminal 420 registers the content in the content management system 410 and creates a smart contract for it (S411). In the smart contract, a monetary price such as a copyright fee to be distributed by the creator may be recorded according to the usage purpose of the content.

In the smart contract, the author's permission to use and the copyright holder's profit distribution rate can be recorded. The permission to use may include the right to write a secondary work. In this case, if the secondary work is registered in the content management system 410, the percentage of the revenue share or the amount of revenue of the creator who allowed the creation of the secondary work for the secondary work is applied to the smart contract as a condition for permission to create the Can be included.

Next, the promotion server 430 creates a smart contract for promoting the corresponding content (S412). The promotion server 430 may be, for example, an Internet portal site. In the contents of the smart contract created by the promotion server 430, the PR server 430 is recorded in return for the promotion cost per number of times that information on the corresponding content is provided to the consumer terminal, or the content is promoted for a specific period. Promotional costs for acting on behalf of the company can be recorded in return. In addition, information on how to distribute profits from promotion may be recorded. Next, the content management system stores the content information registered by the creator terminal 420 and the promotion server 430 and the created smart contract in the blockchain (S413).

Next, the consumer terminal 440 creates a smart contract for using future content. In the case of transferring money using a blockchain system, a certain amount of time delay occurs in the transfer of the money as multiple approvals for the transmission are required from nodes involved in the transmission. In order to avoid this delay, certain smart contract items may be added between the consumer and the content management system 410.

In one embodiment, the consumer terminal 440 and the content management system 410 remit a predetermined amount from the consumer account to the content management system 410 in advance, and a smart contract in which a content usage fee is deducted and paid within the amount. Can be concluded. Remittance of the amount may be a specific type of electronic money or remittance of an amount according to the currency of a specific country.

The consumer terminal 440 and the content management system 410 set a period in the smart contract, and when the period has elapsed, the remaining balance after use by the consumer from the amount transferred from the consumer account to the content management system 410 Rules for resending money back to the consumer account can be entered. Accordingly, as the period elapses, the smart contract is automatically executed, and the balance remaining in the content management system 410 may be remitted to the consumer account.

In another embodiment, the consumer terminal 440 and the content management system 410 freeze a certain amount from the consumer account to prevent withdrawal to another account, and conclude a smart contract in which the content usage fee is deducted and paid within the frozen amount. can do. Even in this case, by setting a period in the smart contract, the freeze on the balance can be automatically terminated after the period has elapsed. To this end, the consumer account may have electronic money operated by a blockchain with the option to stop withdrawal of a certain amount of electronic money. In the blockchain, whether or not to freeze the amount item corresponding to the amount frozen in the electronic money account and the item of the person who has canceled the freezing can be maintained as shown in the table below.

In Table 1, UTXO # represents the unspent transaction outputs. The associated account represents the address of the account to which the corresponding UTXO is connected. The amount is the amount of electronic money designated for the UTXO. Whether the UTXO is frozen indicates whether the corresponding UTXO has been frozen, and 1 may indicate frozen and 0 may not be frozen. Terminators 1 to 3 indicate the address of the account that must be approved in order to terminate the freezing.

To explain, the UTXO 1 item is an unused output value connected to account A, and the balance including UTXO 1 is displayed in account A. However, the amount corresponding to 324 in account A is frozen and the amount cannot be transferred to another account unless the freeze is canceled as in UTXO 2. In order to remit the amount of UTXO 1, approval of the right holders B and C is required.

For the efficiency of the data structure for expressing whether or not it is frozen, as shown in Table 2, the field on whether or not to be frozen is removed, and only the address of the right of revocation can be entered. Like UXTO 2, if the item of the right to cancel 1 is 0, it can be determined that the UXTO is not frozen.

In addition, the content management system 410 may enter into a smart contract for content transmission in order to compensate peers transmitting the content data when the content data is transmitted in a P2P transmission method. The smart contract for content transmission may include distributing a price for transmitting the content data to peer accounts that have provided the data file according to a certain standard.

For example, the smart contract for content transmission may be performed by remittance of data transmission to the peer that transmitted the data file when all data of the content has been transmitted to the consumer terminal 440. The content management system 410 receives whether the transmission is complete from the peer that transmitted the data file, and after receiving the completion of reception from the consumer terminal 440 that received the data, pays the price for the data transmission to the peer that transmitted the data file. can do. And such history can be recorded on the blockchain.

In an embodiment, the content management system 410 may enter into a smart contract for content transmission in order to compensate peers transmitting the content data when content data is transmitted through bittorrent. The smart contract for content transmission may include distributing a fee for transmitting the content data to the bittorrent relay server and peer accounts that provided the torrent data piece of the data file according to a certain standard.

For example, in the smart contract for content transmission, when all data of the content is transferred to the consumer terminal 440, the payment for the BitTorrent relay server is transferred to an account corresponding to the BitTorrent relay server, and the data It can be performed by sending the pieces to each peer that has transmitted the pieces by dividing the price to be provided to the peers according to the ratio of the pieces of data successfully transmitted by the peers. As described above, BitTorrent relay servers and peers participating in the transmission of content data, data fragments transmitted by peers, and completion of transmission of peers and consumer terminals may be recorded in a blockchain.

Content information acquisition

A step in which the consumer terminal 440 acquires content information through the promotion server 430 will be described. First, the consumer terminal 440 transmits a content inquiry request to the promotion server 430 (S421). Accordingly, the promotion server S430 sends a content inquiry request (S422) to the content management system 410, and transmits the received content inquiry result to the consumer terminal 440 (S423, S424). Then, the content management system 410 stores the content inquiry history in a block chain (S425).

According to an embodiment, the promotion server 430 may receive and store content information from the content management system 410 in advance. In this case, the promotion server 430 may transmit the retained information to the consumer terminal 440 without requesting the content inquiry result from the content management system 410. The publicity server 430 may transmit the content inquiry history to the content management system 410, and the content management system 410 may store the inquiry history in the blockchain (S425).

Content data transmission

Next, a step in which the consumer terminal 440 downloads content data will be described. The consumer terminal transmits a content provision request to the content management system 410 (S431). The content management system 410 may transmit content data according to the request of the consumer terminal 440.

The content management system 410 may review the execution details of the smart contract prior to transmitting the content data. The content management system 410 may review the smart contract for the creator and the smart contract for the promotion server for the corresponding content, and receive money from the consumer terminal 440 for executing the smart contract.

In addition, the content management system 410 may additionally review a smart contract for content transmission in order to compensate peers transmitting the content data when the content data is performed in a P2P transmission method such as BitTorrent. have. The content management system 410 may transmit the content data to the consumer terminal 440 after confirming that all the corresponding amounts have been remitted.

The content management system 410 may transmit content data to the consumer terminal 440 by executing a smart contract for content use (S432). The content management system 410 stores content data as a consumer executes a smart contract with the content management system 410 through a consumer account in order to reduce the procedure and waiting time for receiving payment from the consumer terminal 440. It can be transmitted to the terminal 440. For example, content data may be transmitted while deducting an amount previously remitted from the consumer account to the content management system 410. Alternatively, by executing a smart contract on the unused balance of the frozen payment in the consumer account, the amount corresponding to the consideration of the content use is transmitted to the content management system, and the corresponding amount is the content management system 410 Content data can be transmitted to the consumer terminal 440 without checking whether the deposit is made to the account of ).

According to the above processing, the consumer terminal 440 may download the corresponding content data and consume the content (S434).

Distribution of the usage fee

When the content management system 410 receives payment for content use from the consumer terminal, the content management system 410 distributes the money to the creator, the promotion server, and the server and peers participating in the content transmission to be settled. Can be (S441). The content management system 410 may distribute the proceeds to equity holders who have a stake in the content profit according to the smart contract stored in the block chain. In addition, the content management system 410 may store the distribution result in the blockchain (S442).

Smart contract renewal

Regarding the distribution of contents, by updating the smart contract to the equity holders who have shares through the smart contract, the profits for the contents can be changed.

In the case of the consumer terminal 440, when a smart contract is concluded with the content management system 410 and the balance is less than the set threshold or the set expiration period has expired, the amount is consumed according to the use of the content. The contract may be re-signed, and this may be automatically executed according to the existing smart contract (S451). Such contract update may be stored in the blockchain by the content management system 410 (S452).

Hereinafter, another embodiment of distributing content using the content management system 100 will be described. 5 and 6 illustrate an embodiment in which content data is distributed to the consumer terminal 540 through the content relay system 530. In the embodiment of FIG. 4, the content management system 510 directly transmits the content data to the consumer terminal 540, but for this purpose, the consumer terminal 540 must enter into a smart contract with the content management system. This makes it difficult for the consumer terminal 540 that cannot enter into a smart contract or a consumer who uses it to access the system.

In addition, when the number of consumer terminals 540 accessing the content management system 510 increases significantly, a problem occurs in that the content management system 510 is overloaded. In addition, when the physical distance between the content management system 510 and the consumer terminal 540 is very long enough to perform intercontinental communication, a problem of lowering the transmission efficiency may occur. In order to solve this problem, the content management system 510 may distribute content data to the consumer terminal through the content relay system 530.

In one embodiment, the content management system 510 and the content relay system 530 are connected through a dedicated line for intercontinental communication, and the content relay system 530 and the consumer terminal 540 are connected by a normal communication line. , It is possible to increase the communication efficiency between the content management system 510 and the content relay system 530.
