Description

{System for protection of trade content by verifying transaction sender}

As a system for protecting transactions of digital content, more specifically, it relates to a system for preventing illegal or improper use of exchanges and for preventing harm caused by transactions of digital content with uniqueness through confirmation and verification of the owner, and is a technical field for a content transaction protection system through verification of digital content authority information.

NFT (Non-Fungible Token) is a blockchain token with non-fungible information added. It uses blockchain encryption technology to give separate, unique identification information to digital files such as pictures, videos, and music, and has the advantage of being able to prove the originality, authenticity, and uniqueness of digital files.

However, there are copyright issues before issuing tokens (NFTs) that grant uniqueness. In the case of digital data that is not granted uniqueness, there may be a risk that it can be easily copied, and if tokens granting uniqueness are made for someone else's work, copyright issues may arise.

In the case of NFT, various digital assets including digital art are traded through exchanges, and minting, which issues tokens (NFTs) that grant uniqueness through the platform, takes place.

More than 85% of NFTs actually created within platforms (e.g. OpenSea) are plagiarized or fake, and there are cases where there were actual problems with transactions.

There are technical attempts to solve existing problems in digital content transactions that grant uniqueness, for example, there is a prior patent document, "Method for Determining and Monitoring Infringement/Forgery of NFT Content Based on Intellectual Property Rights Database (Registration No. 10-2410669, hereinafter referred to as Patent Document 1)".

In the case of the patented invention according to Patent Document 1, the method for determining whether or not NFT content is in conflict/forgery based on the intellectual property database and for monitoring the same includes (a) a step of storing user NFT (Not Fungible Token) content designated by the user in the upload database of the management server, (b) a step of the communication unit of the management server accessing the selected intellectual property database, (c) a step of the content comparison unit of the management server comparing images included in documents existing in the intellectual property database with the user NFT content stored in the upload database through a pre-input image comparison algorithm to determine whether there is an image having a similarity level higher than a preset standard, and (d) a step of the tag setting unit of the management server assigning a similarity warning tag to the user NFT content if it is determined as a result of the determination in step (c) that there is an image having a similarity level higher than the preset standard.

In addition, there exists a “Method, device, and system for digitalizing real assets based on blockchain (Registration No. 10-2355550, hereinafter referred to as Patent Document 2).”

In the case of Patent Document 2, a method for providing a transaction service for real assets based on blockchain is provided, comprising: a step of matching a real asset with a non-fungible token (NFT); a step of setting a first user as the owner of the real asset; and a step of changing the second user to the owner of the real asset when a second party purchases the real asset from the first user.

As a prior literature on an evaluation method for an exchange, there is, for example, "Method for evaluating whether to list a cryptocurrency exchange using an artificial neural network (Publication No. 10-2020-0130767, hereinafter referred to as Patent Document 3)".

In the case of patent document 3, a method for evaluating whether to list a blockchain cryptocurrency exchange using an artificial neural network, which is performed by a server, includes the steps of collecting metadata of ICO cryptocurrency; performing deep learning on the collected metadata of ICO cryptocurrency using a training data set; and outputting information on the success of the ICO based on the deep learning result information and external evaluation information.

In the case of the existing patent documents 1 and 2, verification of NFT is done through a method of establishing a database of intellectual property rights and owners of real assets, and in the case of patent document 3, it is mentioned that information on cryptocurrency exchanges is evaluated through machine learning.

In reality, verification is being conducted in a different way from the verification of whether the entity that issued the NFT and the creator are the same, which is currently a problem in NFT transactions, and whether the NFT corresponds to an exchange where it is being traded illegally or fraudulently.

The present invention seeks to protect transactions regarding NFTs by 1) verifying the legitimacy of the transaction site and 2) verifying that the seller (transaction sender) matches the actual creator when trading digital content.

The system for protecting transactions of digital content through verification of rights information of digital content according to the present invention relates to a system for protecting transactions of digital content (1) to which uniqueness has been granted, and provides reference information to a purchaser who wishes to trade digital content (1) during transactions of digital content (1) traded on a blockchain, and protects transactions of digital content (1) through verification of the rights holder of the digital content (1).

A content transaction protection system through verification of digital content authority information according to the present invention comprises a purchaser terminal unit (100), an owner terminal unit (200), a transaction unit (300), and a verification unit (400).

First, the purchaser terminal unit (100) obtains a request signal to obtain digital content (1) and ultimately obtains the digital content (1) according to the request signal.

In the case of digital content (1), it refers to digital content (1) to which uniqueness has been granted, and means that a token (2) has been granted within the digital content (1) using blockchain technology.

In the case of digital content (1) granted with uniqueness, it may mean a non-fungible token (NFT), and in the case of uniqueness, it may indicate the unique originality and ownership of the digital content (1).

In the case of the purchaser terminal unit (100), a purchaser's request signal can be obtained and digital content (1) can be obtained according to the request signal.

As illustrated in FIG. 1, the purchaser terminal unit (100) may be a network-capable device, such as a personal computer (PC), a smart phone, a tablet computer (such as an iPad), a notebook computer, or a desktop computer, that is connected to a network and is capable of inputting and outputting data.

In the case of a consumer terminal unit (200), the digital content (1) is directly or indirectly held, and the digital content (1) is transmitted to the purchaser terminal unit (100) according to an acceptance signal based on a request signal.

The consumer terminal unit (200) may store or retain digital content (1) in its own wallet, for example, to enable the digital content (1) to be traded, and may also retain digital content (1) by uploading the digital content (1) to an exchange and retaining it in the exchange.

In the case of the owner terminal unit (200), digital content (1) can be transmitted to the purchaser terminal unit (100). In the case of the digital content (1), it can be transmitted from the owner terminal unit (200) to the purchaser terminal unit (100) through the exchange.

In the case of the owner terminal unit (200), it is also desirable that it be network-capable, such as a PC (Personal Computer), smartphone, tablet computer (iPad, etc.), notebook computer, or desktop computer, which is connected to a network and can input and output data.

In the case of a transaction unit (300), an acceptance signal for accepting a request signal is provided according to a request signal of a purchaser terminal unit (100), and a task of transmitting digital content (1) from an owner terminal unit (200) to a purchaser terminal unit (100) is performed.

In the case of a transaction unit (300), the right to ownership of digital content (1) can be converted, so that information on the ownership of the digital content (1) can be converted.

The verification unit (400) provides certain reference information of the transaction unit (300) in response to a request signal from the purchaser terminal unit (100) and verifies the transaction of digital content (1) by confirming the rights holder of the digital content (1).

In the case of the verification unit (400), when the purchaser trades digital content (1), it is intended to prevent the use of illegal or fraudulent exchanges, and when the purchaser terminal unit (100) trades digital content (1), reference information about the exchange can be provided to provide guidance about the exchange.

For example, when a transaction for digital content (1) is made using the purchaser's smartphone, the verification unit (400) enables verification of the exchange through information about the exchange, and if the exchange is suspected of being an illegal or fraudulent exchange after verification, a push notification can be provided to the purchaser's smartphone saying, "The site you are trying to trade on is not safe."

The verification unit (400) of the content transaction protection system through verification of authority information of digital content according to the present invention is configured to include trade management (410).

In the case of trade management (410), variable data that selectively allocates a variable verification area for verification criteria of digital content (1) transactions through predetermined reference information can be provided to the purchaser terminal unit (100) when trading digital content (1).

In the case of certain reference information, it may include information about the exchange and information that can be used to determine and verify illegal or fraudulent exchanges.

Specified reference information can be collected and stored through a database server, as illustrated in FIG. 5.

In addition, a variable verification area can be selectively allocated through reference information. In the case of a variable verification area, for example, it can be variably determined through reference information whether identity verification has been performed at the exchange, whether a transaction has proceeded smoothly, or whether a verifiable account has been confirmed.

By setting a variable verification area, the exchange's illegal or faulty verification criteria can be set for the data given from each exchange, and the verification area can be set variably.

The verification unit (400) of the content transaction protection system through verification of authority information of digital content according to the present invention is configured to include a certificate management unit (420).

In the case of the certificate management department (420), when a request for digital content (1) is generated from the purchaser terminal unit (100), the authority information for the digital content (1) can be provided to the purchaser terminal unit (100).

The certificate management department (420) aims to prevent sleepminting during transactions by verifying the transaction sender that occurs during transactions for digital content (1).

In the case of slipminting, it can mean that invalid uniqueness has been granted through forgery or alteration that is different from the original author's intention.

In the case of a transaction sender, it may correspond to a sender who sends digital content (1) when trading digital content (1), and may correspond to a seller or owner.

The certificate management department (420) can verify and confirm the authority information for a transaction by verifying the relationship between the transaction sender and the creator.

The verification unit (400) of the content transaction protection system through verification of authority information of digital content according to the present invention may include an application providing unit (401), a variable area setting unit (402), a transaction safety confirmation unit (403), and a verification information providing unit (404).

First, in the case of the application provider (401), a service application is received from the purchaser terminal unit (100) and the purchaser terminal unit (100) is requested to install an app for the service.

Information of the verification unit (400) is provided to the purchaser through the purchaser terminal unit (100), and it is preferable to provide information to the purchaser through an application for the service.

At this time, the application provider (401) may request installation of the app on the purchaser terminal unit (100).

To explain in more detail the installation of an application (App) and the provision of services and information through the application, as shown in FIG. 5, a purchaser can apply for a service to receive services regarding information provided by the verification unit (400).

Applications for services can be made by authenticating the purchaser through payment using identity verification.

The purchaser is instructed to install an app that can use the verification unit (400) according to the service requested, and this can be done by requesting the installation of the app to a customer who has completed payment for the use of the app, and causing the app to be installed.

In the case of the verification unit (400), consent to provide related information on digital content (1) stored in the purchaser's wallet, cloud, etc. may be requested.

Information related to digital content (1) previously agreed upon by the purchaser can be transmitted to the database (DB) server of the verification unit (400).

Afterwards, a service can be initiated that provides reference information held by the verification unit (400) to the purchaser.

In addition, when a buyer trades digital content (1) by utilizing the buyer's digital content information stored in a database (DB) server, information can be provided to enable a safe transaction.

In the case of the variable area setting unit (402), certain reference information on the exchange of digital content (1) is collected, and a variable verification area for verification criteria is assigned from the certain reference information to form variable data.

As for the description of the verification criteria, as explained above, the verification area is variably allocated and set for the verification criteria, and details on the verification criteria will be described later in the description of the variable area setting section (402).

In the case of the transaction safety verification department (403), when requesting a digital content (1) transaction, the safety of the digital content (1) transaction is verified through variable data.

In the case of the transaction safety verification unit (403), the safety of digital content (1) can be verified. In the case of safety, the safety of the transaction unit (300) that wishes to trade the digital content (1) is verified. It is preferable that the safety of the transaction unit (300) be verified through variable data.

For example, when a transaction of digital content (1) is requested through a purchaser terminal unit (100), verification is performed on the transaction unit (300) in which the transaction of the digital content (1) is made, and verification of the transaction unit (300) can be performed through variable data among the reference information included in the verification unit (400).

For the transaction unit (300), if it is confirmed that there is false or illegal transaction information among the variable data, it can be notified that the transaction unit (300) is an unsafe site.

In the case of the verification information provision department (404), when a digital content (1) transaction is requested, the authority information of the digital content (1) is verified and authority verification information for the digital content (1) is provided through the authority information.

As illustrated in FIG. 3, the verification unit (400) can verify authority information for digital content (1) and provide authority verification information for the digital content (1) to the purchaser terminal unit (100).

The variable area setting unit (402) of the content transaction protection system through verification of digital content rights information according to the present invention collects data for a predetermined reference, and determines information for the predetermined reference variably for at least one of i) transaction information of digital content (1); ii) account verification information for the rights holder of digital content (1); or iii) identification information for the rights holder of digital content (1), and includes it within the range of variable data.

For variable data, this may correspond to a list of explicitly permitted access, movement, services, specific permissions, and recognition for some identified exchanges.

For the scope of variable data, it can be set variably depending on the extent to which the standards for the exchange's verification scope are recognized.

For example, in the case of identity verification information, the identity verification information may be set based on whether the identity verification information is verified through a credit card, resident registration number, or identity verification through SNS.

In the case of account verification, it is carried out variably according to the laws of each country, and the reference point may be set differently.

In the case of transaction information, it may correspond to the exchange's transaction history, and the transaction history may include information on transaction accidents, delays in deposits, delays in interest, and violations of counter obligations.

It is desirable that the range of such variable data be expandable or contractible.

In the case of variable data, for example, it can correspond to data on whether an exchange is a safe exchange, and through variable data, it can be confirmed whether the exchange is within the risk zone or outside the risk zone.

The transaction safety verification unit (403) of the content transaction protection system through verification of authority information of digital content according to the present invention provides transaction risk information on digital content (1) when the exchange is not within the variable data range during digital content (1) transaction.

In the case of transaction risk information, it can be provided through the buyer terminal unit (100), for example, it can be provided through an app push notification of the buyer terminal unit (100).

Transaction risk information may correspond to safety information about the exchange you are trading on, and may provide information through phrases, icons, sound notifications, vibration notifications, text notifications, etc. that can confirm that the site or app you are attempting to trade on is unsafe.

In the case of the verification unit (400) of the content transaction protection system through verification of authority information of digital content according to the present invention, whether the public key and private key of the digital content (1) are used is checked, and if the digital content (1) is unique by using the public key, the transaction of the digital content (1) is restricted.

When issuing uniqueness to existing digital content, the public and private keys can be stored and used during the initial NFT creation process.

In the case of a public key, it is public, and in the case of a private key, it is not public and is a key that is used secretly and cannot be known by anyone other than the individual.

When storing and using public and private keys, it is desirable that the personal signature of information on the issuance of uniqueness at the time of use be sealed and stored within the digital content, and at the same time, data on the use of the public and private keys be issued simultaneously, combined with the personal signature, and stored in a sealed manner.

In the case of existing NFT issuance (minting), there was a problem in that invalid uniqueness was granted through falsification (sleepminting) that was different from the original author's intention by indicating the transaction sender by verifying the public key on the exchange.

In the case of the verification unit (400) of the content transaction protection system through verification of authority information of digital content according to the present invention, the transaction sender can be verified at the time of transaction to verify whether uniqueness has been issued to the digital content (1) through a public key or whether uniqueness has been issued to the digital content (1) through a private key.

In addition, if digital content (1) is uniquely identified using a public key, it is possible to provide guidance on limiting or restricting transactions.

In the case of the verification unit (400) of the content transaction protection system through verification of authority information of digital content according to the present invention, when a digital content (1) transaction of a purchaser terminal unit (100) is performed, variable data and authority information are cross-checked through an app for the service to cross-verify the digital content (1) transaction of the purchaser terminal unit (100).

In the case of the verification unit (400), it is desirable to cross-verify transactions for digital content (1) by verifying information about the exchange and authority information about the digital content (1).

Problems with conventional digital content transactions include the use of illegal or fraudulent exchanges, and problems with digital content transactions (1) when the creator and seller of the digital content are not the same.

The present invention aims to prevent this problem by cross-checking and verifying digital content (1) authority information for creators and sellers, while checking for illegal or fraudulent exchanges, and thereby verifying transactions.

The content transaction protection system through verification of digital content authority information according to the present invention may further include a sharing unit (500).

In the case of a sharing unit (500), it is formed by a plurality of nodes, and when uniqueness is generated in digital content through a private key or public key through a plurality of nodes, it is shared for a transaction generated in digital content (1), as shown in FIG. 8.

In the case of a transaction of digital content (1), it refers to a record of an event that occurred in the digital content, which corresponds to information about an event that occurred in the digital content (1).

For example, when uniqueness is issued using a private key for digital content (1), the event for issuing uniqueness is shared among multiple nodes.

For multiple nodes, information on transactions for shared digital content (1) is shared and merged.

A plurality of nodes are formed into a preset cluster, and when a transaction for digital content (1) occurs in one of the plurality of nodes, it is desirable to compare transaction information shared in the plurality of nodes, and determine whether to modify or change an event for the transaction information through one of the plurality of nodes.

Through the process of sharing transactions across multiple nodes, the process of issuing uniqueness to digital content (1) is shared and stored across all multiple nodes.

In addition, it is desirable for multiple nodes to perform a cross-match comparison on transactions to check whether events for digital content (1) are mutually consistent, and for events for digital content (1) stored in each node to be aligned.

For example, if an event of digital content (1) occurs at one node but matching between nodes is not achieved, information that is not sourced from the purchaser terminal unit (100), the owner terminal unit (200), the transaction unit (300), and the verification unit (400) is selectively removed, and matching of the event of digital content (1) between nodes is achieved.

In the event that digital content (1) has uniqueness generated by using a private key or shared key, trust in digital data for which uniqueness has been issued can be secured by sharing it with multiple nodes, and the verification unit (400) can enable verification through multiple nodes when confirming whether a public key and private key have been used.

The scope of the rights of the present invention is determined by the matters described in the claims, and the parentheses used in the claims are not described for optional limitation, but are used to indicate clear elements, and the description within the parentheses should also be interpreted as essential elements.
