1 is a diagram showing the configuration of a platform providing system according to an embodiment of the present invention.

The system for providing a platform according to an embodiment of the present invention may support trading of copyright-backed securities, which are digital assets owned by one user, with another user.

Specifically, the platform providing system may include a platform supporting server 100 that provides a transaction service of digital assets (eg, copyright-backed securities) and a plurality of user devices 200 that want to trade digital assets (copyright-backed securities). there is. Furthermore, the user device may include a first user device 201 that wants to sell digital assets owned by the user and a second user device 202 that wants to buy digital assets (copyright-backed securities).

The server 100 may receive a digital asset sale request signal from the first user device 201 that wants to sell the digital asset. At this time, the server 100 sends a digital asset sale request signal along with digital asset information (e.g., digital asset type, digital asset issuer, investment (purchase price), interest rate (return rate), etc.) and transaction information (e.g., sales price, Transaction conditions such as types of exchangeable assets) may be requested from the first user device 201 .

The server 100 can also determine the safety of the digital asset as it receives information about the digital asset, and if it is determined that the safety level is higher than the standard value, it will support the transaction of the digital asset to other users through the trading platform. can

In addition, the server 100 may receive purchase conditions from a user (second user) who accesses to purchase digital assets, and may search for or recommend products corresponding to the purchase conditions. The purchase condition may correspond to, for example, information on the type of product (copyright-backed securities), a price to be purchased, and the like.

In addition, when the server 100 searches for and recommends a product corresponding to the purchase condition input by the second user and confirms the user's consent to purchase, the server 100 may perform an operation of selling the corresponding product.

In addition, the server 100 may perform a selling operation of the corresponding product as the second user directly selects one product from among products registered and posted on the trading platform and requests purchase.

In addition, when the transaction is completed, the server 100 records the transaction details in the transaction ledger of the block chain, and can simplify the authentication procedure for the same product by referring to the recorded contents when re-transacting the same product later.

2 is a diagram for explaining an operation of trading digital assets in a platform according to an embodiment of the present invention.

As shown in FIG. 2, the platform according to an embodiment of the present invention provides not only digital assets (eg, copyright-backed securities) issued by one company, but also digital assets (copyright-backed securities) issued by various types and various companies. We can support trading services.

Specifically, in the trading platform according to an embodiment of the present invention, when an owner wants to sell copyright-backed securities issued by Company A, the corresponding asset (copyright-backed securities) can be registered as a sales product from the owner. Also, if there is a user requesting purchase of a pre-registered product, the server 100 supporting the transaction platform may perform a series of processes for selling the product. As the selling operation is performed, ownership of the copyright-backed securities may be transferred from the first user, the original owner, to the second user, the purchaser. In this case, the price for selling the digital asset by the first user to the second user may be paid to the account of the first user.

In this way, when the ownership of the digital asset is changed through the sales process, the target to be distributed the profits of the digital asset (eg, copyright securitization) later from the company A becomes the second user, the changed owner, not the first user.

When a transaction product (copyright-backed securities) is registered for sale, the server 100 providing the transaction platform service determines the transaction price at an amount to which a certain discount rate is applied, so that the transaction can be conducted promptly.

In addition, the server 100 may automatically charge fees for using the platform to users who are transaction participants. At this time, the platform use fee is automatically deducted in value corresponding to the transaction amount as the transaction is made, and the platform server 100 can be provided.

The fee may be paid to the trading platform, for example, in a step in which a first user registers a digital asset to be sold on a trading platform or in a step in which a digital asset registered to be sold by a first user is traded to another user.

According to various embodiments, the sale price of digital assets may be paid not only in cash but also in various forms of funds such as cryptocurrency, stocks, and precious metal certificates.

As the owner of the digital asset is changed through a transaction, the profit dividend for the corresponding security must be transferred to the second user, the changed owner. The process of transferring the profit to the second user can be done in various ways. For example, when the second user purchases a copyright-backed securities issued by company A from the first user, the server 100 provides changed owner information (eg, account information) to the affiliated company A and receives approval. Through this process, profit dividends can be directly deposited into the account of the second user. Alternatively, the server 100 allows the first revenue delivery of the amount to be provided to the first user who sold the copyright-backed securities to the account on the platform server 100, and then the server 100 to the second user who is a digital asset purchaser. You can also help make the delivery of revenue happen. If the distribution of profit dividends made by other companies is made through the platform server 100 in this way, the server 100 may deduct a predetermined fee when delivering the dividends.

In the case of implementation by firmware or software, an embodiment of the present invention may be implemented in the form of a module, procedure, or function that performs the functions or operations described above. The software code may be stored in the memory and driven by the control unit. The memory may be located inside or outside the user terminal and server, and data may be exchanged with the control unit by various means known in the art.

The control unit 130 according to an embodiment of the present invention may perform a series of operations required for an issuer to trade various digital assets on the same platform.

Specifically, the control unit 130 according to an embodiment of the present invention may include a sales request confirmation unit 131, a transaction asset evaluation unit 132, a blockchain management unit 133, and a transaction support unit 134. Through each of these components, the control unit 130 confirms the value of the digital asset to be traded, certifies suitability as a traded subject, and private blockchain-based products (copyright-backed securities) whose suitability is certified as a traded subject It is possible to perform management operations and actual transaction operations of trading objects (copyright-backed securities).

Among the components of the controller 130, the sales request confirmation unit 131 first receives a sales request from the first user and can check it. Upon receiving a sales request from the first user, the sales request confirmation unit 131 may request the first user to input seller information in order to check whether the first user meets seller requirements. For example, the seller requirements may be based on the input of personal information such as the seller's name and date of birth, and other requirements may include registration of sales history information, registration of seller account information, and the like.

In addition, the sales request confirmation unit 131 may receive information about the type, quantity, and sales price of products to be sold from the first user and check them. The sale request confirmation unit 131 determines whether or not the blockchain management of the digital asset requested for sale is confirmed, and if it is confirmed as a product under blockchain management, it can confirm whether previous transaction details exist. The sales request confirmation unit 131 determines whether the product requested for sale is managed by blockchain, and if the product is not under blockchain management, the transaction asset evaluation unit 132 goes through an authentication procedure and starts blockchain management, and then registers sales data. action can be performed. At this time, blockchain management may mean that transaction details are recorded on a transaction of a blockchain for a digital asset.

The transactional asset evaluation unit 132 may evaluate whether a blockchain management condition for a corresponding product is satisfied with respect to a product for which blockchain management is not performed. Specifically, the transaction asset evaluation unit 132 determines the type of digital asset that the first user wants to register as a product, the safety of the digital asset, and the monetary value of the corresponding digital asset, and evaluates whether the blockchain management conditions are satisfied based on this. can

In addition, the transaction asset evaluation unit 132 may perform an operation of authenticating a digital asset to be traded as a tradable asset when confirmation of the authenticity of the digital asset that the user intends to trade is completed. At this time, assets that can be traded on the integrated trading platform according to an embodiment of the present invention may include various types of digital assets. Preferably, assets traded on the integrated trading platform according to an embodiment of the present invention may include copyright-backed securities issued using copyrighted works as underlying assets.

The transaction asset evaluation unit 132 is based on the number of personal authentication items of the owner of the product to be traded (Criterion 1) and the difference between the result of converting the value of the product into an amount and the seller's request price (Criterion 2). to evaluate the safety of the product. In addition, the server 100 may determine whether the product can be registered according to the safety of the corresponding product. For example, if the safety of the copyright-backed securities determined by the trading asset evaluation unit 132 is less than the standard value, the server 100 may notify that the securities cannot be registered as a product for sale and may reject the registration.

On the other hand, the server 100 approves the product registration of the security when the safety value of the product evaluated by the transaction asset evaluation unit 132 is higher than the standard value, and notifies the user accessing the platform of the safety value so that the user can refer to it when trading can help

The transaction asset evaluation unit 132 may include a type confirmation unit 131a, a safety evaluation unit 131b, and a value evaluation unit 132c.

A more detailed description of the transaction asset evaluation unit 132 will be described with reference to FIG. 4 .

Blockchain can be used to record and manage a shared ledger used by multiple people. According to an embodiment of the present invention, the blockchain management unit 133 records the transaction information (owner change information, transaction price, etc.) of the digital asset in the transaction of the blockchain when a digital asset whose transaction suitability is verified is traded on the integrated transaction platform. can do.

For reference, the private blockchain used in the embodiment of the present invention is a blockchain in which only authorized entities (organizations) with legal responsibility create transactions, unlike public blockchains in which anyone can access data and create transactions. means network method. Because the target to participate in the blockchain network is clear, there is no need to issue a cryptocurrency, which is an incentive system, and participants who can participate in the reading, writing, and consensus process are designated in advance, and new subjects can be added or removed as needed. This method is mainly used by financial institutions.

A private blockchain is a centralized network method and has many differences from a public blockchain in that only authorized entities participate in transaction creation. In particular, the fact that the scope of information sharing can be set in a private blockchain and the existence of an operating subject can mean that anonymity is not guaranteed. This feature can reduce problems caused by anonymity. In addition, since only authorized subjects can participate in the network, the transaction processing speed is faster and the amount of transactions that can be processed is significantly higher than that of the public blockchain method, which goes through the process of checking transaction details from all participants in order to create a block. there is

The blockchain management unit 133 may support records of transactions performed through the transaction support unit 134 in a ledger through a blockchain network. Accordingly, transaction information (eg, ownership transfer history of the same product, etc.) of all digital assets traded through the integrated transaction platform according to an embodiment of the present invention may be recorded in a private blockchain ledger.

As such, the blockchain management unit 133 may record transaction information in a blockchain transaction for a transaction of a product that is determined to be registered as a product for sale, and the transaction data of the blockchain recorded in this way can verify its validity in future transactions. Can be checked for verification.

Among the configurations of the control unit 130, the transaction support unit 134 may perform a series of processes required for a digital asset (copyright-backed securities) registered as a sales product to be transacted with another person on the integrated trading platform.

The transaction support unit 134 may include a transaction condition confirmation unit 133a, a transaction condition adjustment unit 133b, a transaction target recommendation unit 133c, and a transaction execution unit 134d.

A more detailed description of the transaction support unit 134 will be described with reference to FIG. 5 .

4 is a diagram showing the configuration of a trading asset evaluation unit according to an embodiment of the present invention.

As shown in FIG. 4 , the transaction asset evaluation unit 132 may include a type confirmation unit 132a, a safety evaluation unit 132b, and a value evaluation unit 132c.

As described above, the trading asset evaluation unit 132 evaluates the type, safety, and exchange value of the product to be traded, and if the evaluation standard is satisfied, it can be certified as a tradable asset. The authenticated digital asset can be registered as a product for trading on the trading platform as requested by the user, and data management based on the blockchain can be applied by the blockchain management unit 133. Accordingly, the detailed information of the authenticated digital asset is recorded in a blockchain-based public ledger, and transaction-related information such as future transaction history and transaction conditions of the corresponding asset may also be recorded in a blockchain transaction.

Among the configurations of the transaction asset evaluation unit 132, first, the type confirmation unit 132a may perform an operation of confirming the type of digital asset and classifying the digital asset according to the identified type. In this case, the types of digital assets may include, for example, copyright-backed securities, P2P principal and interest receivables, and real estate-backed securities. In addition, in the case of copyright-backed securities, the type confirmation unit 132a may classify more subdivided types such as share ratio, contract period, copyright type, and copyright type.

In order to determine whether the copyright-backed securities requested for sale are safe products suitable for trading, an operation for evaluating the value of a work that is the basis for issuing the security (hereinafter referred to as basic work) is required. To this end, the server 100 of the present invention can obtain value evaluation information of the basic work from an expert who can appraise the value of the work, and measure the asset value of the corresponding product (copyright-backed securities) based on the value evaluation information. . To proceed with this process, the transaction asset evaluation unit 132 may perform an operation to check the type of underlying work of the corresponding copyright-backed securities.

When classifying the type of the work, the type confirmation unit 132a may perform a primary classification operation for classifying the work into text, music, art, and program. In addition, the type checking unit 132a may perform a second classification operation subdivided by one level from the first classification standard, and the second classification operation standard may include, for example, a genre, an artist, a company, and the like.

The safety evaluation unit 132b may perform a safety authentication operation based on information about the seller of copyright-backed securities in order to confirm safety from fraud and counterfeiting.

Specifically, the safety evaluation unit 132b may evaluate the safety value of the corresponding product higher as the number of personal authentication items of the product seller (first user) increases.

Personal authentication items may include, for example, first user's phone number authentication, address authentication, e-mail authentication, account authentication of a digital asset issuer, transaction history authentication, and the like.

Among them, the transaction history authentication may mean confirming and authenticating that there is no fraudulent transaction history or fraudulent activity of the user trying to register a product for sale.

Specifically, the safety evaluation unit 132b inquires the user's fraudulent transaction attempt history (fraud history) requesting the transaction of copyright-backed securities on the trading platform, and performs an authentication operation (transaction history) to confirm that there is no fraudulent transaction history of the user. authentication) can be performed. In this case, the safety evaluation unit 132b may determine whether a user is a bad user by inquiring all fraudulent transaction histories confirmed at the time of purchase as well as sales of one user.

In addition, according to various embodiments, the safety evaluation unit 132b calculates the probability of fraudulent transactions compared to the entire transaction history of the user based on the transaction history recorded in the blockchain-based ledger, and the safety value corresponding to the calculated probability information. can be calculated (the lower the probability of fraudulent transaction, the higher the safety value). For example, even if there are users A and B who do not have identical fraudulent transaction histories, in the case of B having more transaction histories than A having no transaction histories, the safety value may be measured as a higher value.

The safety evaluation unit 132b may determine that criterion 1 is satisfied when it is confirmed that there is no history of fraudulent transactions of users who want to sell copyright-backed securities on the trading platform. The safety evaluation unit 132b may evaluate whether criterion 1 is satisfied and safety in response to the personal authentication degree of the corresponding user as well as the fraudulent transaction history. For example, the safety evaluation unit 132b may evaluate the safety value as a high value for a seller's product in which the user's personal information is described in detail and the number of personal authentication items is large.

In addition, the safety evaluation unit 132b may include an issuer evaluation unit (not shown), and through the issuer evaluation unit, credit evaluation of the company that issued the copyright-backed securities may be performed. The issuer evaluation unit may evaluate securities issuers through, for example, a user reporting system. Specifically, the issuing company evaluation unit inputs the name of the company from the users, the product for which the overdue or non-payment occurred, and the number of times when the copyright proceeds dividend is overdue or non-paid from users who have purchased copyright-backed securities through the trading platform. can receive

Accordingly, the issuing company evaluation unit may calculate companies having a payment rate of income equal to or less than the standard value, and subtracting (eg, -2) a safety value for products issued by these companies.

For reference, the issuer evaluation unit may determine the type of product whose payment rate for each company is higher than or equal to the standard value (excellent) or the type of work whose payment rate for each company is higher than the standard value. In this case, if it is determined that the product requested by the seller belongs to the type of work for which the issuer has a payment rate equal to or greater than the standard value, the issuer evaluation unit may calculate the safety value of the product by adding it (eg, +2).

The value evaluation unit 132c may perform a series of operations to check the asset value of the copyright-backed securities and measure the safety of the product therefrom.

The value evaluation unit 132c may evaluate the safety of the product in response to the degree of difference between the result of converting the value of the product to be sold and the selling price of the seller.

The value evaluator 132c may analyze the copyright (hereinafter referred to as copyright based on issuance) that is the issuance basis of the copyright-backed securities and estimate the copyright revenue of the corresponding work in order to determine the degree of the gap. The value evaluator 132c may evaluate the asset value of the copyright-backed securities by converting them into money based on the current value and expected profit of the analyzed issuance copyright. Thereafter, the value evaluation unit 132c may calculate the difference between the selling price of the product desired by the seller (first user) and the converted asset value of the copyright-backed securities, and may evaluate safety according to the degree of the difference. At this time, as the difference increases, the safety may be calculated as a lower value.

According to an embodiment, when determining the asset value of copyright-backed securities, the value evaluation unit 132c evaluates the underlying asset for the copyright issued by the first user who wants to sell the copyright-backed securities or the related copyright-backed securities issuer. Data can be received, and based on the received underlying asset evaluation data (e.g., copyright share ratio, original copyright holder information, copyright type information, copyright revenue status, etc.), the asset value of the copyright-backed securities can be evaluated.

At this time, the value evaluator 132c may evaluate the asset value based on information related to the issuance of the securities, such as the time the securities were issued and the company that issued the securities, in addition to the information on the copyright on the basis of issuance.

In addition, the value evaluator 132c matches a potential value evaluator according to the classification information classified by the type confirmation unit 132a, and evaluates the asset value of the copyright-backed securities in consideration of the potential value evaluation information by the potential value evaluator. .

Specifically, for example, the value evaluation unit 132c may include, for example, a potential value evaluation unit (not shown). The potential value evaluation unit may request potential value evaluation from a plurality of evaluator accounts for each type or genre of the underlying work of the asset-backed securities. The value evaluation unit 132c, for example, when a product is classified as 'music (first classification)-hip-hop (second classification)', in order to evaluate the potential value of the product, in the field of 'music-hip-hop' You can grant multiple evaluator accounts the right to view samples for evaluation of the product and request evaluation. The potential value evaluation unit may evaluate the asset value of a corresponding product (copyright-backed securities) based on evaluation information of potential value evaluators on the underlying works of a product.

In addition to the purpose of evaluating the safety of a product before it is registered for sale, the value evaluation unit 132c may evaluate an asset value to inform a purchaser of the value of the product. For this purpose, the asset value of the copyright-backed securities converted into numerical values by the value evaluation unit 132c may be disclosed to a plurality of users accessing the platform to purchase digital assets.

5 is a diagram showing the configuration of a transaction support unit according to an embodiment of the present invention.

When a product (copyright-backed securities) is requested to be registered as a product for sale, the transaction support unit 134 checks the suitability of the transaction determined by the transaction asset evaluation unit 132, and confirms that the product is certified as a tradable asset. can be registered as a product for sale.

In addition, the transaction support unit 134 checks whether the transaction conditions of the day copyright-backed securities registered as sales products are input more than the standard number, determines whether the input transaction conditions are appropriate in comparison to the asset value of the product, and receives information from other users.
