Entity) and HSS (Home Subscriber Server), etc. In addition, the network according to the present invention may include an Internet network, which is a conventional network in which information is exchanged according to the TCP/IP protocol. It means an open communication network, that is, a public network.

The contract server 10 is an entity that exists on a network, and is a device capable of performing computing operations and communicating through a network. The contract server 10 is a server for executing and managing contracts according to an embodiment of the present invention.

The plurality of nodes 20 and 30 include a client node 20 and a general node 30 . Each of the nodes 20 and 30 is a device capable of performing computing operations and communicating through a network. In particular, the plurality of nodes 20 and 30 constitute a blockchain network. The nodes 20 and 30 may be any device that performs computing operations, executes a virtual machine (VM) through computing operations, stores data, and performs communication through a network.

The platform server 40 is a server operated by an operator that provides various content-based platform services. Such a service may exemplify a user-created content (UCC) service, an over-the-top media (OTT) service, and the like.

Both the provider device 50 and the consumer device 60 are devices used by users, and among them, the provider device 50 is a device used by a user playing the role of a content provider, and the consumer device 60 is a device used by a user. It is a device used by a user who plays the role of a content consumer who watches, that is, consumes. Of course, a single user can play both roles of a content provider and a consumer, but to clarify the gist of the invention, it will be described separately. Both the supplier device 50 and the consumer device 60 are devices capable of performing computing calculations and communicating through a network.

In particular, the nodes 20 and 30, the provider device 50, and the consumer device 60 can be applied to various terminals such as all information communication devices, multimedia terminals, wired terminals, fixed terminals, and IP (Internet Protocol) terminals. For example, the nodes 20 and 30, the provider device 50, and the consumer device 60 may exemplify a personal computer, a laptop computer, a mobile phone, a smart phone, a tablet, a phablet, and the like.

Then, a method for performing settlement according to a contract based on a smart contract according to an embodiment of the present invention will be described. 2 is a flowchart for explaining a method of storing a contract based on a smart contract according to an embodiment of the present invention.

Referring to FIG. 2, the operator of the platform server 40 creates a draft contract, creates a contract, and according to the operation of the operator who wants to store the generated contract, the platform server 40 transmits the contract server 10 through the network. ) to access. The contract server 10 may provide the drafting page to the platform server 40 in step S110. Accordingly, the platform server 40 may display the contract creation page so that the user can view it. The contract creation page provides an input form including mandatory and optional elements that must be entered in the standard contract form. In particular, the required elements must include the ratio of profit distribution at the time of settlement, and are preferably in the form of a table.

Business operators can input element values for mandatory elements and optional elements that they want to input through an input form. According to the operator's input, the platform server 40 transmits the element value. Then, the contract server 10 receives element values for essential elements and optional elements from the platform server 40 in step S120, and stores the received element values according to the elements including the corresponding required elements and optional elements. . In this case, it is preferable that the element values to be stored are stored in a PDF (Portable Document Format) format. In addition, the contract server 10 generates a contract in a standard contract format based on the element values received in step S130 and stores the generated contract.

Next, the contract server 10 generates smart contract code in step S140, compiles the generated smart contract code (source code), and generates bytecode executable in a virtual machine (e.g., Ethereum Virtual Machine, EVM). . In the embodiment of the present invention, the smart contract code (byte code) creates a program that stores and updates contract data, issues contracts based on contract data, and performs settlement according to contract details. This will be explained in more detail below.

Next, the contract server 10 obtains a binary interface (eg, ABI (Application Binary Interface) code) in step S150, and then compiles into bytecode executable in the virtual machine using the binary interface (ABI) in step S160. Create an execution contract object containing the smart contract code.

Subsequently, the contract server 10 generates a transaction including an execution contract object in step S170 and transmits the generated transaction to the client node (CN) of the blockchain network.

Then, the plurality of nodes 20 and 30 including the client node 20 of the blockchain network verify the validity of the transaction in step S180, that is, perform proof-of-work and generate and distribute blocks. That is, the execution contract object including the smart contract code compiled into the bytecode included in the transaction provided to the client node (CN) can be stored in the blockchain through a proof-of-work process between a plurality of nodes in the blockchain network. The proof-of-work process is as follows. The miner node collects transactions generated in the blockchain network and includes them in a block, and encrypts the hash value of the previous block, the merkle root, and the nonce together using a hash function to register the block in the blockchain. The miner node changes the nonce value until the hash value derived from the encryption result is smaller than the target value. If a nonce value smaller than the target value is found, the nonce is stored in the n-th block and the generated block is propagated to nodes participating in the blockchain network to store the block containing the transaction in the blockchain. When creating these blocks, a contract address is created. The contract address is a unique address given to the smart contract code. Among the plurality of nodes in the blockchain network, the miner node provides the contract address created at the time of block generation to the contract server 10. That is, the contract server 10 receives the contract address in step S190.

Upon receiving the contract address, the contract server 10 extracts the contract data in step S200 and creates a data contract object. That is, the contract server 10 extracts contract data indicating only the contents of the contract itself, excluding contents related to privacy such as personal information from the previously created contract (step S130). For example, assuming that the content of the contract is a revenue distribution ratio for revenue generated when a user watches a specific content, only the distribution ratio of beneficiaries A and B can be extracted. Then, the contract server 10 creates a data contract object that allows the smart contract code of the contract address to be executed based on the contract data.

Then, the contract server 10 creates a transaction including the data contract object in step S210 and transmits the generated transaction to the client node CN of the blockchain network. Then, a plurality of nodes including client nodes (CN) of the blockchain network verify the validity of the transaction, that is, perform proof-of-work, and generate and distribute blocks in step S220. That is, the data contract object included in the transaction provided to the client node (CN) is stored in the blockchain through a proof-of-work process between a plurality of nodes in the blockchain network. This proof-of-work process is as described above (step S180). This means that the contract data of the data contract object is stored in the blockchain. In addition, the virtual machine of the blockchain network can execute the smart contract code (byte code) based on the contract data of the execution contract object.

Next, a method for performing settlement according to a contract based on a smart contract according to an embodiment of the present invention will be described. 3 is a flowchart for explaining a method for performing settlement according to a contract based on a smart contract according to an embodiment of the present invention.

Meanwhile, the contract server 10 may receive a request for contract data from contracting parties such as the platform server 40 , the supplier device 50 and the consumer device 60 in step S310 . Then, the contract server 10 finds a block in which the contract data is stored and a transaction in the block using the contract address and the binary interface in step S320 and loads the contract data.

Next, the contract server 10 converts the contract data into XML format or JSON format in step S330.

According to one embodiment, when changing the contract data into an XML format, the contract processing unit 140 sets Java Annotations and converts the contract data into an XML format using "XmlAccessorType". At this time, the contract processing unit 140 may set a root by setting a "rootElement" command for each element including essential elements and optional elements of the contract data. According to another embodiment, when changing the contract data to JSON format, the contract server 10 may change the contract data received from the blockchain network to JSON format through "HTTPMessageConvertor" with reference to the Jaxson2 library.

Subsequently, the contract server 10 may transmit the contract data converted into XML format or JSON format in step S340 to the device of the contracting party, such as the platform server 40 and the provider device 50. Then, the contracting parties can perform settlement according to the transmitted contract data.

Next, a method for performing settlement based on a contract based on a smart contract according to another embodiment of the present invention will be described. 4 and 5 are views for explaining a method for performing settlement based on a contract based on a smart contract according to another embodiment of the present invention.

Prior to the full-scale description of FIG. 4, the embodiment of FIG. 4, as described in steps S110 to S220 of FIG. 2, the platform server 40 generates a standard contract through the contract server 10, and the contract server ( 10) distributes the smart contract code for contract management, extracts contract data from the standard contract, and transmits the contract data to the blockchain network (BCN) through a transaction so that the contract data is stored in the blockchain network (BCN) , The virtual machine (EVM) of the blockchain network (BCN) executes the smart contract code based on the contract data.

On the other hand, according to the operation of the content provider who wants to supply the content to the platform server 40, the provider device 50 transmits a contract content request message requesting viewing of the contract content to the platform server 40 in step S410. The contract content request message includes the address of the provider device 50 . Then, the platform server 40 transmits the contract content request message to the contract server 10 in step S420, and the contract server 10 takes the address of the provider device 50 as a factor in step S430 and generates a smart contract code (byte Code) transmits a transaction that calls the contract details providing function. At this time, the transaction uses the contract address as a medium.

The contract content providing function according to an embodiment of the present invention basically converts the contract data stored in the blockchain into XML format or JSON format, and then delivers it to the destination address specified in the transaction, that is, the address of the provider device 50 play a role Accordingly, when the transaction is transmitted and the proof-of-work process is completed between the plurality of nodes 20 and 30, a virtual machine is executed on any one node 20 or 30 among the plurality of nodes 20 or 30, The executed virtual machine executes the contract content providing function. Accordingly, the virtual machines of the nodes 20 and 30 convert the contract data stored in the blockchain into XML format or JSON format in step S440, and then return to the destination address specified in the transaction, that is, the address of the provider device 50. play a role in conveying Accordingly, the supplier device 50 may receive contract data and display the received contract data on the screen. Then, the provider reviews the contents of the contract data and, when agreeing to the contract, transmits an acceptance message through the provider device 50 in step S450.

Then, upon receiving the acceptance message in step S460, the contract server 10 transmits an acceptance message including the address of the provider device 50 that transmitted the received acceptance message through a transaction. Accordingly, when the transaction is transferred and the proof-of-work process is completed between the plurality of nodes 20 and 30, the address of the supplier device 50 is stored by being mapped to contract data with the same account in the blockchain. This means that the status of the content provider under the contract is recognized.

Meanwhile, a content consumer who wants to view content on the platform server 40 can also request, view, and accept contract details through the consumer device 60 through steps S470 to S520. Steps S470 to S520 differ only in that the party to the contract is a content consumer rather than a content provider, and proceeds in the same way as steps S410 to S460. Therefore, detailed description thereof is omitted.

Finally, when the acceptance message is delivered to the blockchain network (BCN) through a transaction, the proof-of-work process is completed between a plurality of nodes (20, 30), and it is mapped to the same account as the contract data within the blockchain to the consumer device ( 60) is stored. This means that the status of a content consumer is recognized under the contract.

Referring to FIG. 5 , after the contract is completed, it is assumed that the provider device 50 uploads the content to the platform server 40 in step S570 by manipulation of the content provider. Then, the platform server 40 generates content identification information, which is information capable of identifying the uploaded content in step S580, and transmits the generated content identification information to the contract server 10. The content identification information includes, for example, a content identifier, an address where the content is stored, access information on a viewing record log indicating a record of viewing the corresponding content, and the like. Then, the contract server 10 generates a transaction including content identification information in step S590 and transmits the generated transaction to the blockchain network (BCN). Accordingly, after the transaction is transferred, when the proof-of-work process is completed between the plurality of nodes 20 and 30, a virtual machine is executed on any one node 20 or 30 among the plurality of nodes 20 or 30. , the executed virtual machine starts the settlement process in response to the content identification information. At this time, the virtual machine specifies the contract data corresponding to the content identification information and manages the same account.

Meanwhile, when the content is uploaded, the consumer device 60 can view the corresponding content through streaming by accessing the platform server 40 in step S600 by manipulation of the content consumer. In this way, whenever content is viewed, the consumer device 60 stores a viewing record log, which is a record of content viewing, in step S610. The viewing record log includes, for example, a content identifier, a content address, a viewing time, and a date.

Meanwhile, the platform server 40 also creates a viewing record log in step S620 whenever content viewing is performed. The viewing record log of the platform server 40 further includes the identifier of the consumer device 60 that viewed the corresponding content in the viewing record log of the consumer device 60 .

In addition, whenever the platform server 40 generates a viewing record log, it transfers the viewing record log to the contract server 10 in step S630. Then, the contract server 10 stores the viewing record log in step S640.

On the other hand, after the virtual machine of the blockchain network (BCN) starts the settlement process, at least one of the contract server 10, the platform server 40 and the consumer device 60 is operated at a random cycle and a random number of times within the settlement cycle. Collect verification data from one random subject. Here, the verification data is a viewing record log stored in each of the contract server 10, the platform server 40, and the consumer device 60.

All three of these viewing record logs must match. Therefore, it would be most accurate to continuously collect and store all corresponding viewing record logs, but there is a problem of storage space and load.

Therefore, the present invention collects verification data, which is part of the viewing record log, from at least one random object among the contract server 10, the platform server 40, and the consumer device 60 at random cycles and at random times within the settlement period. collect

In this way, when the settlement date arrives while collecting verification data, the platform server 40 transmits sales data for the content uploaded by the corresponding provider device 50 in step S660. The sales data basically includes a viewing record log, and indicates sales generated in response to the viewing record log.

The contract server 10 receiving the sales data generates a transaction including the sales data in step S670 and transmits the generated transaction to the blockchain network (BCN). Accordingly, when the transaction is transferred and the proof-of-work process is completed between the plurality of nodes 20 and 30, the virtual machine of any one node 20 or 30 among the plurality of nodes 20 or 30 operates at step S680. Verify sales history. That is, the virtual machine compares sales data with pre-collected verification data to verify errors or omissions in sales.

As a result of the verification, if there is no abnormality in the sales data, the virtual machine proceeds from sales of the sales data based on the contract data in step S690 to each of the platform server 40 side operator and the provider device 50 side content provider, Settlement is performed including a fee using the blockchain network-based settlement service of the contract server 10 and a cost provided as a benefit for the verification data provided by the consumer device 60.

Then, the virtual machine transmits the settlement result to the contract server 10, the platform server 40, the supplier device 50 and the consumer device 60 in step S700. In this way, according to an embodiment of the present invention, the reliability of profit distribution according to settlement is improved by making settlement through a blockchain network according to a contract based on a contract.
