Hereinafter, the service providing device 100 described with reference to FIG. 1, the service providing device 200 described with reference to FIG. 2, the user terminal 300, and the server 400 according to the present invention. A specific process for the NFT-based service provision method applied to the metaverse space according to one embodiment can be described in more detail with reference to FIGS. 3 to 10.

Figure 3 is a flowchart illustrating an NFT-based service provision method applied to the metaverse space according to an embodiment of the present invention.

Referring to FIG. 3, the NFT-based service providing method applied to the metaverse space according to an embodiment of the present invention includes the service providing device 100 described with reference to FIG. 1 and the service providing device 100 described with reference to FIG. 2. It may be performed by the service providing device 200, the user's terminal 300, and the server 400, and more specifically, it may be performed under the leadership of the service providing device.

First, the service providing device matches the NFT issued for the registered sound source of the platform providing metaverse space and an identifier to identify the sound source to generate an NFT ID used to manage the sound source on the platform. (S100).

Here, the specific process of generating an NFT ID used to manage sound sources on the platform by matching the identifier for identifying the sound source and the NFT issued for the registered sound source of the platform that provides metaverse space in the service providing device is It can be described in more detail below with reference to FIG. 4.

Figure 4 is a flowchart showing a method of generating an NFT ID in an NFT-based service provision method applied to the metaverse space according to an embodiment of the present invention.

Referring to Figure 4, a service providing device that performs an NFT-based service providing method applied to the metaverse space according to an embodiment of the present invention includes ownership, copyright, average transaction amount, and number of transaction history of sound sources registered on the platform. By collecting information about the management status level and management status level, a blockchain-based NFT containing each information can be issued (S110).

Specifically, when an event requesting registration of a sound source occurs on the platform, the service providing device is the terminal of the user who generated the event requesting registration of the sound source, which provides information on the ownership of the sound source, copyright, average transaction amount, and number of transaction history. You can request information.

First, the service providing device requests information from the user's terminal about the owner of the sound source requesting registration on the platform, information about the author holding the copyright, information about the amount of past transactions, and information about the number of past transactions. You can obtain it by doing this.

At this time, the service providing device is based on the information on the number of past transactions obtained by receiving it from the user's terminal and the information on the past transaction amount, and the degree of change in the transaction amount (slope through a graph for the amount for each transaction, etc.) ) can be confirmed, and the management status grade can be determined based on preset standards for the degree of confirmed change.

For example, assuming that the management status level is divided into three types (high, intermediate, and low) based on preset standards, the service providing device has a slope value that can check the change in transaction amount for the music source in advance. If the slope value of the set standard is exceeded, the management status level can be determined to be high.

On the other hand, if the slope value that can confirm the change in the transaction amount for the sound source is the same as the slope value of the preset standard, the service providing device may determine that the management status level is intermediate. In addition, the service providing device may determine that the management status level is low when the slope value that can confirm the change in the transaction amount for the sound source is less than the slope value of the preset standard.

Afterwards, the service providing device can issue a blockchain-based NFT to include information on the ownership, copyright, average transaction amount, number of transaction history, and management status level of the finally confirmed music source. In this way, a service providing device may refer to a device capable of performing the function of issuing a blockchain-based NFT.

Afterwards, the service providing device can generate an identifier format having a structure of a plurality of fields for each information included in the NFT and match each information to be stored in each field included in the identifier format to generate the NFT ID of the sound source ( S120).

Specifically, the identifier format may refer to the format of a unique identifier, such as a universally unique identifier (UUID), and is an identifier having a structure of a plurality of fields that can store information generated based on a plurality of items within the identifier. It can mean format. At this time, the identifier format may have at least a field containing a number of items corresponding to information set to be included in the NFT in the service providing device.

Meanwhile, the service providing device can match each information included in the NFT to each field included in the identifier format, and process each matched information to be stored in each field so that all information included in the NFT is stored in the identifier format. When stored, the creation of the NFT ID of the sound source can be completed by additionally reflecting the unique identification value for the NFT ID of the sound source (for example, a value such as a serial number that can identify the ID itself).

Again, referring to Figure 3, the service providing device performing the NFT-based service providing method applied to the metaverse space according to an embodiment of the present invention uses the NFT ID based on a preset encryption method to protect the sound source on the platform. It can be encrypted and stored in the platform's database by matching it with the sound source corresponding to the NFT ID (S200).

Specifically, the service providing device can pre-set an encryption method to protect the sound source, and more specifically, set a plurality of encryption methods in advance and then select one encryption method among the plurality of encryption methods to use the sound source. It can be set as required conditions.

In other words, in order to utilize a sound source in the metaverse space, the sound source can be in a usable state by decrypting it based on the encryption method. In addition, the NFT ID for the sound source and the information contained in the NFT can be confirmed by decrypting the NFT ID for the sound source based on the encryption method for the sound source.

Afterwards, the service providing device can provide services by processing events related to sound sources based on the NFT ID for events related to sound sources generated by a plurality of users connected to the metaverse space provided by the platform (S300 ).

Here, the events related to the sound source that the service provision device determines to provide the service are the first event requesting registration of a new sound source on the platform, the second event requesting the purchase of the copyright of the sound source registered on the platform, and the metaverse space. It may be one of a third event requesting streaming of a sound source registered on the platform and a fourth event requesting download of a sound source registered on the platform.

Specifically, the service providing device requests verification of the NFT ID for the sound source corresponding to the event related to the sound source to the user's terminal that generated an event related to the sound source, and matches the sound source and the sound source based on the verification result received from the user's terminal. A response to a related event can be transmitted to the user's terminal.

Here, the service providing device requests verification of the NFT ID for the sound source corresponding to the event related to the sound source to the user's terminal that generated the event related to the sound source, and based on the verification result received from the user's terminal, the information related to the sound source is requested. The specific process of transmitting a response to an event to the user's terminal can be described in more detail below with reference to FIGS. 5 to 10.

Figure 5 is a flowchart showing a method of processing a first event in an NFT-based service provision method applied to the metaverse space according to an embodiment of the present invention.

Referring to Figure 5, when the service providing device performing an NFT-based service providing method applied to the metaverse space according to an embodiment of the present invention determines that an event related to a sound source is the first event, a new sound source The information required to generate the first sound source and the NFT ID for the first sound source can be requested from the terminal of the first user who generated the first event (S311).

First, the service providing device provides information about the ownership, copyright, average transaction amount, and number of transaction history of the first sound source, which is the information required to issue the NFT of the first sound source, to generate the NFT ID of the first sound source. Information can be requested from the first user's terminal.

Afterwards, the service providing device can encrypt the NFT ID generated based on the information required to generate the NFT ID of the first sound source using an encryption method, match the encrypted NFT ID with the first sound source, and store it in the database (S312 ).

Here, the specific process of storing the NFT ID for the first sound source, which means a new sound source, in the database of the platform in the service providing device may be similar or the same as previously described with reference to step S200 of FIG. 3.

Thereafter, the service providing device may transmit authentication information verifying that the first sound source is registered on the platform, an NFT ID for the first sound source, and information about the encryption method of the NFT ID for the first sound source to the first user's terminal. (S313).

Specifically, when the NFT ID for the first sound source is completely stored in the platform's database, the service providing device can generate authentication information authenticating the registration of the platform for the first sound source, and more specifically, in the platform. It may mean a value such as an issued authentication number. For example, the accreditation information may include the name of the platform, which may indicate the certification authority, the date the certification was performed, and the serial number for the certification.

In other words, as a result of processing the first event, the service providing device provides information authenticating the registration of the first sound source to the first user's terminal, an NFT ID that identifies the NFT of the first sound source, and decrypts the first sound source. This can provide information about the encryption methods that can be used.

Figure 6 is a flowchart illustrating a method for processing a second event in an NFT-based service provision method applied to the metaverse space according to an embodiment of the present invention.

Referring to Figure 6, when the service providing device performing the NFT-based service providing method applied to the metaverse space according to an embodiment of the present invention determines that the event related to the sound source is the second event, the second event Payment of the amount for which the copyright of the second sound source, meaning the sound source corresponding to, is being sold can be requested to the terminal of the second user who generated the second event (S321).

First, if the service providing device determines that the event related to the sound source is a second event, it may request information about the amount for which the copyright of the second sound source is being sold to the platform server. Accordingly, the server may receive a request for information about the amount for which the copyright of the second sound source is being sold from the service providing device.

Afterwards, the platform's server can check information about the amount for which the copyright for the second sound source is being sold in the platform's database. Thereafter, the server of the platform may transmit information on the amount for which the copyright for the confirmed second sound source is being sold to the service providing device. Accordingly, the service providing device can receive information about the amount for which the copyright for the second sound source is being sold from the platform server.

Thereafter, the service providing device may transmit information on the amount for which the copyright for the second sound source is sold to the second user's terminal, and more specifically, may pay the amount for which the copyright for the second sound source is sold. It is possible to support the second user to make a payment on the second user's terminal by requesting that the user interface provided is provided on the second user's terminal.

Thereafter, when it is determined that payment has been completed, the service providing device may request update-required information among each information included in the NFT of the second sound source to the second user's terminal (S322).

For example, the service providing device may include the name of the owner related to the ownership of the sound source that requires updating and the author related to the copyright among the information about the ownership, copyright, average transaction amount, and number of transaction history of the sound source included in the NFT of the second sound source. Information about the name, etc. can be requested from the second user's terminal.

Accordingly, the second user's terminal receives the name of the owner related to the ownership of the sound source that requires updating among the information about the ownership, copyright, average transaction amount, and number of transaction history of the sound source included in the NFT of the second sound source from the service providing device. You can receive requests for information about the name of the author related to copyright, etc. Thereafter, the second user's terminal can selectively transmit information that needs to be updated among the information included in the NFT for the second sound source to the service providing device.

Thereafter, the service providing device may generate the NFT ID of the second sound source by updating the information included in the NFT of the second sound source based on the update required information received from the second user's terminal (S323).

Specifically, the specific process of generating the NFT ID of the second sound source in the service providing device may be similar or identical to the process of generating the NFT ID previously described with reference to step S200 of FIG. 3.

Thereafter, the service providing device may provide a service that transmits information about the second sound source, the NFT ID of the second sound source, and the encryption method of the NFT ID for the second sound source to the second user's terminal (S324).

In other words, the service providing device can be utilized by decoding the second sound source, the NFT ID that can identify the NFT of the second sound source, and the second sound source to the second user as a result of processing the second event requesting purchase of the copyright. It can provide information about the encryption method available.

In other words, the result of processing the second event may mean providing information about the second sound source, the NFT ID of the second sound source, and the encryption method for the second sound source to the second user's terminal.

A service providing device that performs an NFT-based service provision method applied to the metaverse space according to an embodiment of the present invention through the method described above provides a service related to an object called 'sound source' in the metaverse space. It can be provided to multiple users accessing . In particular, the service providing device of the present invention can manage sound sources by applying information on the NFT ID and encryption method to protect the 'sound source' in the process of providing services related to the object called 'sound source' in the metaverse space. .

Meanwhile, a service providing device that performs an NFT-based service provision method applied to the metaverse space according to an embodiment of the present invention provides NFT of the sound source based on the management status level determined in the process of generating the NFT ID for the sound source. You can determine the rating for the NFT, and manage the sound source based on the determined rating for the NFT.

For example, first, as previously described, the service providing device according to an embodiment of the present invention may assume that the management status level of the sound source is divided into three levels (high, intermediate, low), and in such a situation You can create a graph of the amount of each transaction based on the number of past transactions for music and the amount of past transactions.

Afterwards, the service providing device can calculate the slope of the graph and compare the calculated slope with the slope value of a preset standard as a standard for determining the grade. Here, the value of the slope of the preset standard may mean a value for determining the degree to which the price for the sound source increases or decreases during the transaction process.

Afterwards, if the slope value of the graph exceeds the slope value of the preset standard, the service providing device may determine that the price for the sound source has continuously increased, and accordingly determine the management status grade as 'high'. You can.

Afterwards, the service providing device can determine that a sound source with a management status rating of 'high' is a high-value sound source, and can determine the rating for the NFT of a sound source with a management status rating of 'high' as 'high'. . At this time, the service providing device can apply the protection procedure for the NFT of 'high level' to the sound source with the management status level of 'high level'.

For example, a service providing device can provide services related to insurance that compensates for damage in case of an accident due to forgery or alteration of a 'high-grade' NFT. Specifically, the service providing device can transmit information about 'higher-level' NFTs to the server of the platform that provides insurance-related services, and by registering information about 'higher-level' NFTs on the platform's server, the corresponding ' If an accident occurs due to forgery or alteration of information about a ‘high-end’ NFT, you can request insurance to compensate for the damage.

In other words, for 'high-grade' NFTs, if the information contained in the NFT is forged or altered, the service providing device can provide a service that can compensate for damage to the user who is the owner of the NFT through insurance-related services. . In other words, this may mean that the service providing device can provide users with ‘high-end’ NFT stability.

On the other hand, if the slope value of the graph is the same as the slope value of the preset standard, the service providing device may determine that the price for the sound source was relatively normal, and accordingly, determine the management status level as 'intermediate'. there is.

Afterwards, the service providing device may determine that a sound source with a management status rating of 'intermediate' is a sound source of average value, and may determine the rating for the NFT of a sound source with a management status rating of 'intermediate' as 'intermediate'. there is. At this time, the service providing device can apply the 'intermediate' NFT protection procedure to the sound source with the 'intermediate' management status level.

For example, a service providing device may provide a security service that further applies an additional encryption method to the information contained in the NFT to detect forgery and alteration of the 'intermediate' NFT. Specifically, the service providing device may apply different encryption methods used to encrypt the NFT and the encryption method used to encrypt the NFT ID.

That is, when the service providing device applies the first encryption method to encrypt the NFT, a second encryption method that is different from the first encryption method may be applied to encrypt the NFT ID. Through this, the service providing device can provide a service that applies a double encryption method to detect forgery and alteration of 'intermediate' NFTs.

In addition, if the slope value of the graph is less than the slope value of a preset standard, the service providing device may determine that the price for the sound source has been continuously lowered, and accordingly set the management status level to 'low'. can be decided.

Afterwards, the service providing device can determine that a sound source with a management status rating of 'low' is a high-value sound source, and can determine the rating for the NFT of a sound source with a management status rating of 'low' as 'low'. . At this time, the service providing device can apply the protection procedure for the 'low-level' NFT to the sound source with the 'low-level' management status level.

For example, the service providing device can provide advertising services related to sound sources corresponding to 'low-level' NFTs in the metaverse space so that the amount for 'low-level' NFTs can be increased. Specifically, the service providing device can advertise or promote sound sources corresponding to 'lower-level' NFTs by providing streaming of sound sources corresponding to 'lower-level' NFTs to multiple users accessing the metaverse space.

In other words, the service providing device can provide a service to increase the amount of 'low-level' NFTs registered on the platform, which has the effect of increasing the average value of sound sources registered on the platform.

Meanwhile, a service providing device that performs an NFT-based service providing method applied to the metaverse space according to an embodiment of the present invention can issue blockchain-based virtual currency, which can purchase the copyright for the sound source on the platform. Alternatively, it may refer to a means that can be used to request permission for streaming and downloading.

At this time, when a user accessing the platform registers a sound source on the platform, the service providing device can provide blockchain-based virtual currency to the user who registered the sound source in return for registration of the sound source. For example, the service providing device may grant a preset amount of virtual currency to the terminal of a user who has registered a sound source on the platform in return for registration of the sound source.

Afterwards, the service providing device requests permission for the user's terminal holding virtual currency to purchase the copyright for the sound source or to stream and download it in the metaverse space implemented by the server of the platform linked to the service providing device. You can grant permission to use virtual currency to do so.

In other words, the blockchain-based virtual currency issued by the service providing device can be used not only for services related to sound sources registered on the platform, but also for the use of services related to sound sources provided in the metaverse space.

To this end, the service providing device can be set to include an identifier of the application space to specify the space to which the virtual currency is applied in the process of issuing blockchain-based virtual currency. For example, the service providing device may be created to include one of a first identifier indicating the space of the platform and a second identifier indicating the metaverse space in the token structure of the virtual currency.

At this time, the user's terminal holding the virtual currency may request the service providing device to convert the identifier included in the virtual currency into the first identifier or the second identifier, and in response, the service providing device may send the first identifier or the second identifier. Conversion to a second identifier may be supported. Through this method, the service providing device can change the space where virtual currency can be applied.

At this time, the space of the platform is a space that supports services related to sound sources other than the metaverse space supported by the platform, and the metaverse space may mean a space within the metaverse service supported by the platform. . In other words, users have the advantage of being able to utilize virtual currency on the music service platform as they choose, as well as within the metaverse space.

Meanwhile, a service providing device that performs an NFT-based service provision method applied to the metaverse space according to an embodiment of the present invention is based on information related to NFTs for a plurality of sound sources registered on the platform. You can select a plurality of sound sources for the performance that can be provided in .

At this time, the platform may be a platform that provides sound source-related services such as basic sound source support, as well as a separate metaverse space. In other words, users can directly use sound sources on the platform or access music source-related services by accessing the metaverse space.

Specifically, the service providing device may receive a request for selection of sound sources for performance from the terminal of one user among a plurality of users accessing the metaverse space. Thereafter, the service providing device may request information about the cost for the performance and information about the number of sound sources for the performance from the user's terminal.

Accordingly, the user's terminal may receive a request for information about the cost for the performance and information about the number of sound sources for the performance from the service providing device. Thereafter, the user's terminal may transmit information about the cost for the performance and information about the number of sound sources for the performance to the service providing device. Thereafter, the service providing device may receive information about the cost for the performance and information about the number of sound sources for the performance from the user's terminal.

Afterwards, the service providing device can extract information about the transaction amount of the sound source from the information related to the NFT for the plurality of sound sources registered on the platform, and based on the information about the transaction amount of the extracted plurality of sound sources, A plurality of sound sources that match the information on cost and the number of sound sources for performance received from the user's terminal can be selected.

Thereafter, the service providing device may transmit information about the plurality of selected sound sources to the user's terminal and request confirmation as to whether the performance will proceed based on the plurality of sound sources selected from the user's terminal. Afterwards, when confirmation of whether the performance is in progress based on the plurality of sound sources selected from the user's terminal is completed, the service providing device may request payment of the amount for the performance for the plurality of selected sound sources to the user's terminal. there is.

Afterwards, when the service providing device determines that payment for the performance for the plurality of selected sound sources has been completed, it may generate content related to the performance based on the plurality of sound sources selected in the metaverse space. Content related to the current performance can be provided in the metaverse space.

At this time, the amount may be paid using the virtual currency described above.
