The service provision method performed on the server may be described in more detail with reference to FIGS. 3 to 5.

Figure 3 is a flowchart showing a service provision method performed on the server of a registration and trading platform for sound sources using blockchain-based NFT according to an embodiment of the present invention.

Referring to FIG. 3, the server of the registration and trading platform for sound sources using blockchain-based NFT according to an embodiment of the present invention includes the server described with reference to FIG. 1 and the service providing server described with reference to FIG. 2. This can mean, and can be performed on devices that operate or manage the platform, such as the server and service provision server described above.

In particular, the server can perform the role of issuing blockchain-based NFTs using 'sound sources' as objects, determining whether issued NFTs are duplicated, registering sound sources for which NFTs have been issued on the platform, and managing the sound sources. and may act as a transaction broker. In this regard, specific embodiments of the present invention for performing the above roles in the platform server may be described in more detail below.

First, the server of the sound source registration and trading platform using blockchain-based NFT according to an embodiment of the present invention acquires sound source information, which means information about the sound source subject to registration on the platform, and analyzes the sound source information. Transaction information, ownership information, and part information included in the sound source information can be extracted (S310).

Specifically, the user terminal, which can refer to the device of a user using the platform, can request the server to register a sound source on the platform or issue an NFT, and accordingly, the server registers the sound source requesting registration on the platform from the user terminal. Information about the target sound source can be requested and obtained. Afterwards, the server may analyze the contents of the sound source information based on a plurality of items included in the sound source information and extract transaction information and ownership information part information for the sound source information.

For example, transaction information may include information on the number of transactions that occurred through the sound source identified in the sound source information, information on the date of the transaction that occurred, and/or information on the amount for each transaction in which the sound source was traded. . Such transaction information can be extracted in the manner shown in Table 1 below. This transaction information may be information about transactions made on other platforms, etc. before the music source requests registration on the platform, and may be information automatically databased by other platforms, etc., or information recorded directly or indirectly by the user. there is.

Additionally, the ownership information may include information about the owner who currently owns the sound source identified in the sound source information and/or information about the date on which the owner's ownership was registered. Such ownership information can be extracted in the manner shown in Table 2 below. This ownership information may be information about changes in ownership on other platforms, etc. before the sound source requests registration on the above-mentioned platform, and may be information automatically databased by other platforms, etc., or information recorded directly or indirectly by the user. It can be.

division owner registration date One Hong Gil Dong 2021.01.26 2 Kang Gam-chan 2021.06.18 3 Admiral Yi 2021.11.02 ?? ?? ??

Additionally, the part information includes information about the playback position of each of a plurality of parts included in the sound source identified in the sound source information. This part information may be information automatically databased by another platform before the sound source requests registration on the platform, or may be information recorded directly or indirectly by the user. In a non-limiting example, the sound source subject to registration in the present invention may be a sound source including the above part information.

Afterwards, the platform server can divide and group the sound source to be registered to create a plurality of partial sound sources and extract partial sound source information (S320).

Specifically, in order to extract partial sound source information, the sound source may first be divided into preset sizes to generate a plurality of first partial sound sources. The preset size may mean a certain running time preset by the platform server. For example, in the case of a sound source with a playback time of 1 minute, if the preset size is 10 seconds, a total of 6 first partial sound sources with each playback time of 10 seconds can be generated. At this time, the first partial sound source including the last playback section may have a playback time of less than 10 seconds.

Thereafter, the plurality of second partial sound sources can be determined by grouping the first partial sound sources corresponding to the same part among the plurality of first partial sound sources using the part information. Part refers to a structure in which the playback contents of a sound source can be classified according to musicological standards, including Intro part, Verse part, Sabi part, Interlude part, and Bridge part. , It may be one or more selected from the group consisting of an outro part and other parts. Other parts may refer to parts that do not correspond to any of the prelude, verse, verse, interlude, bridge, and postlude. These secondary partial sound sources can be determined based on the part information included in the sound source information by analyzing the sound source information. For example, if the preset size for a sound source with a playback time of 2 minutes is 10 seconds and the sound source has the structure shown in Table 3 below, a total of 6 first partial sound sources and a total of 4 secondary partial sound sources will be determined. You can. If a first partial sound source includes two or more parts, the first partial sound source may belong to a second partial sound source that includes the part with a longer playback time.

Play section 1st part sound source part 2nd part sound source 0-10 1st partial sound source (1) Jeonju 2nd partial sound source (1) 10-20 1st partial sound source (2) verse 2nd partial sound source (2) 20-30 1st partial sound source (3) Sabi 2nd partial sound source (3) 30-40 1st partial sound source (4) 40-50 1st partial sound source (5) bridge 2nd partial sound source (4) 50-60 1st partial sound source (6)

At this time, each first or second partial sound source can be managed by assigning a serial number according to the playback order. For example, the first partial sound sources are each serial numbered in a manner such as KA1-001, KA1-002, etc. may be assigned, and the second partial sound sources may be assigned serial numbers in a manner such as KA2-001, KA2-002, etc. Thereafter, the partial sound source information is divided into the number of the plurality of secondary partial sound sources and the plurality of second partial sound sources. It may be determined to include the reproduction time of each of the secondary partial sound sources and an identification number used to distinguish each of the plurality of secondary partial sound sources.

Such partial sound source information can be expected to have the effect of increasing the stability and reliability of the NFT by being used as information included in the NFT to issue a blockchain-based NFT that represents ownership of the sound source, as will be described later. In addition, considering the fact that the importance and transaction value of each part in a specific sound source may vary due to the nature of the sound source, NFT for partial sound sources (especially secondary partial sound sources) for the sound source can be traded. When generating based partial ownership information, the stability and reliability of partial ownership information can be increased by using partial sound source information to match the NFT of the sound source.

In addition, it is possible to facilitate quantification to calculate the value of the secondary partial sound sources by first dividing the sound source into first partial sound sources with a certain length and then grouping them into secondary partial sound sources. In one embodiment, as a standard for evaluating the value of a specific sound source, a value proportional to the playback time and a weight according to the part are preset, and the value obtained by multiplying the value proportional to the playback time and the weight is evaluated as the value of the sound source. method can be applied. For example, if the value according to the playing time of a specific sound source is 10 seconds / 1 won and the weight according to the part is 1x for the intro, 2x for the verse, and 3x for the final part, the second part sound source (1) is 1 (= 10 seconds can be evaluated.

Meanwhile, considering that even with the same sound source, there may be slight differences in playback time due to differences in the blank area at the front or end of the sound source, or the part classification of a specific playback section by the user may be slightly different, partial sound source information is used to determine whether or not to issue duplicate NFTs. It may be advisable not to use it.

Afterwards, the platform's server can issue a blockchain-based NFT that represents ownership of the sound source, including partial sound source information, transaction information, and ownership information. At this time, one or more of the sound source information, transaction information, and ownership information may be encrypted based on an encryption method (S330).

Afterwards, the platform's server may generate detection information including a unique identification value used to determine whether or not duplicate NFTs issued for the sound source are issued based on transaction information and ownership information (S340).

Here, the specific process of generating sensing information including a unique identification value can be described in more detail below.

First, the server of the platform using blockchain-based NFT according to an embodiment of the present invention is the sum of the number of transactions, the average value of the preset number of digits among the plurality of numbers included in the transaction date, and the plurality of numbers included in the transaction amount. The sum of the average value of the preset number of digits can be calculated as the transaction identification value.

For example, the server of the platform can calculate a consensus value for the number of transactions from transaction information in the manner described with reference to Figure 1, and more specifically, taking Table 1 as an example, '1', '2 ' and '3' can be combined to calculate the sum of '6' for the number of transactions. Afterwards, the platform's server can calculate the average value of the preset number of digits among the plurality of numbers included in the transaction date. More specifically, using Table 1 as an example, if the preset number of digits is the 'day of the month digit' , in the first transaction date of '2021.01.23', it can be '1', which is the place of the day of month '01'. Through this method, the platform's server can calculate '2.7' as the average value of '1', '6', and '1'.

In addition, the platform's server can calculate the average value of the number of preset digits among the plurality of numbers included in the transaction amount. More specifically, using Table 1 as an example, if the preset number of digits is the 'hundred's digit', the 1st round In the amount of '580,600 won', '6' can be the 'hundred's place'. Through this method, the platform's server can calculate '5.3' as the average value of '6', '3', and '7'.

Afterwards, the platform's server can calculate '4.6' as the sum of '6', '2.7', and '5.3', which are the values calculated based on the transaction information, and add the calculated value of '4.6' to the transaction information. It can be determined based on the transaction identification value generated.

Afterwards, the platform's server calculates the average value of the preset number of digits among the plurality of numbers included in the serial number preset on the platform for identification of the owner and the preset number of digits among the plurality of numbers included on the date the ownership was registered. The sum of the values can be calculated as the ownership identification value.

For example, the server of the platform may preset the value of the serial number for identification of the owner in the ownership information in the manner described with reference to Figure 2, for example, the serial number for 'Hong Gil-dong' is '202101260001' ', the serial number for 'Kang Gam-chan' can be set to the value of '202106180006', and the serial number for 'Yi Sun-sin' can be set to the value of '202111020017'.

In other words, the server of the platform can set a serial number for each owner based on preset rules for setting the serial number used to identify the owner. This serial number is a unique value within the platform and can be set so that there are no identical values.

Afterwards, the platform's server can calculate the average value of the value of the preset digits among the plurality of numbers included in the serial number set for each owner, and more specifically, if the preset digits are the 'one's digit'. , '4.6' can be calculated as the average value of '1', '6', and '7'.

Afterwards, the platform's server can calculate the average value of the preset digits among the plurality of numbers included in the registration date for each owner, and more specifically, in the case of the preset 'one digit', '2021.01.26' ' can be '6', the one's place. Through this method, the platform's server can calculate '5.3' as the average value of '6', '8', and '2'.

Afterwards, the platform's server can calculate '9.9' as the sum of '4.6' and '5.3', which are the values calculated based on the ownership information, and use the calculated value of '9.9' as a value generated based on the ownership information. It can be determined by the ownership identification value.

Afterwards, the platform's server can calculate a unique identification value by applying a preset calculation algorithm to calculate a unique identification value for the transaction identification value and ownership identification value (S323).

Here, the platform's server can calculate or determine the transaction identification value and ownership identification value as a specific 'number', and a calculation algorithm that can calculate a new 'number' based on the 'number' calculated or determined in this way is preset. It can be.

For example, a preset calculation algorithm may mean an algorithm such as a simple sum algorithm, a simple product algorithm, a simple average algorithm, and a random number generation algorithm that uses the corresponding number as an input value.

Afterwards, the platform's server can be set to include the calculated unique identification value to generate detection information used by the platform to determine whether or not NFTs issued for the sound source are duplicated.

Specifically, the platform's server can convert the calculated unique identification value into a code that can be used in a blockchain-based network, and generate detection information containing a unique identification value in the form of a converted code. can do. In other words, the platform's server can convert information about the 'number' corresponding to the unique identification value into a code that can be used in a blockchain-based network and set it to be included in the detection information.

Sensing information generated through the method described above can be managed by the platform server in the form of a database based on the NFT of the object registered on the platform. In other words, the platform's server can match NFTs issued for a plurality of objects registered on the platform and detection information generated in conjunction with each NFT. Afterwards, the matched information in the form of 'NFT-detection information' can be constructed in the form of a database in connection with the NFT of the platform.

Referring again to FIG. 3, later, detection information including a unique identification value is used to determine whether or not a duplicate NFT is issued, and if no duplicate is issued, the sound source for which the NFT was issued can be registered on the platform (S350).

According to one embodiment, the server of the platform may extract derived sound sources corresponding to each individual instrument used from the sound source, and register derivative ownership information for the derived sound source in the extracted derived sound source on the platform. For example, the derived sound source may include performance results for each song by instrument (e.g., guitar, drum, bass, etc.) used in the original sound source, and depending on the embodiment, is independently generated for each vocal range. It could be. Derivative ownership information can also be generated based on NFT like the partial sound source described above, and those skilled in the art will understand that derived ownership information can also be stored by matching the NFT of the original sound source.

The method of determining whether or not a duplicate NFT is issued may specifically include the following steps.

First, through decryption of a plurality of NFTs pre-registered on the platform, a plurality of identification values for comparison can be calculated based on transaction information and ownership information of sound sources related to the pre-registered NFTs. Specifically, the platform's server can decrypt multiple pre-registered NFTs based on the encryption method used in blockchain-based networks. Afterwards, the platform's server can extract transaction information and ownership information of music sources from the decrypted NFTs based on the encryption method used in blockchain-based networks. A plurality of pre-registered NFTs may mean NFTs for all sound sources previously registered on the platform. At this time, the transaction information and ownership information extracted by the platform server may be similar or the same as described above.

Afterwards, the platform's server can calculate a plurality of comparison target identification values that can mean unique identification values for the pre-registered NFTs based on the transaction information and ownership information extracted for the pre-registered NFTs. . At this time, the comparison target identification value calculated by the platform server may be similar or identical to that described above.

Thereafter, the platform's server may determine that the NFT has not been issued in duplicate if there is no value identical to the unique identification value included in the sensing information among the plurality of calculated identification values to be compared. In other words, if there is one among the pre-registered NFTs whose identification value is the same as the unique identification value of the sound source, the NFT is determined to have been issued in duplicate; otherwise, it is judged not to be duplicated and proceeds to the next step (registering the sound source on the platform). You can skip it.

At this time, if there is a database with matching detection information in connection with the pre-built NFT and NFT, the platform's server can search for 'NFT-sensing information' that needs to be confirmed based on the database, and the searched 'NFT- Based on the value of 'sensing information', it is also possible to compare the unique identification values with the comparison target identification values for pre-registered NFTs to check if they are the same.

For example, the platform's server can search for 'NFT-detection information' for an NFT corresponding to a pre-registered NFT among 'plural NFT-detection information' contained in the database, and 'NFT-detection information' for the retrieved NFT. -Based on ‘sensing information’, you can also compare the comparison target identification value and unique identification value for the pre-registered NFT.

Through such detection information and a method using the detection information, it is possible to prevent duplicate issuance of the same NFT due to malicious intent such as mistake or forgery within the registration and trading platform of sound sources using blockchain-based NFT according to an embodiment of the present invention. In addition, by allowing registration of sound sources and registration of ownership information of partial sound sources only when NFTs are not issued in duplicate, there is an effect of improving the safety, stability, and reliability of NFTs registered on the platform.

Figure 4 shows a service provision method performed on a server that provides a registration and transaction platform for sound sources using blockchain-based NFT according to another embodiment of the present invention.

Figure 4 is the same as the above-described embodiment except that it further includes a step (S360) of generating NFT-based partial ownership information for trading a plurality of partial sound sources by matching information included in the issued NFT.

As mentioned above, considering the fact that the importance and transaction value of each part in a specific sound source may vary due to the nature of the sound source, partial sound sources (especially secondary partial sound sources) for the sound source can be traded. NFT-based partial ownership information can be generated, and the stability and reliability of partial ownership information can be increased by using partial sound source information to match the NFT of the sound source.

At this time, the NFT-based partial ownership information for the transaction of a plurality of partial sound sources may be NFT-based partial ownership information for the transaction of a plurality of secondary partial sound sources. For example, NFT-based partial ownership information for a secondary partial sound source can be generated in a form that includes 'transaction information + ownership information + partial sound source information' of the sound source. The NFT-based partial ownership information includes the ownership information of the sound source (=original sound source), so the NFT-based partial ownership information and the NFT of the sound source (=original sound source) can be stored in a mapped form.

Meanwhile, the server of the platform described in the present invention has been described as issuing blockchain-based NFTs, but may not necessarily be limited to this. In other words, a blockchain-based NFT may be issued through the blockchain management server previously described in the present invention, and in this case, detection information, transaction information, and ownership information, which are the information required for blockchain-based NFT, can be stored in the block. You can also issue a blockchain-based NFT by sending it to a chain-based server.

Methods according to the present invention may be implemented in the form of program instructions that can be executed through various computer means and recorded on a computer-readable medium. Computer-readable media may include program instructions, data files, data structures, etc., singly or in combination. Program instructions recorded on a computer-readable medium may be specially designed and constructed for the present invention or may be known and usable by those skilled in the computer software art.

Examples of computer-readable media may include hardware devices specifically configured to store and execute program instructions, such as ROM, RAM, flash memory, etc. Examples of program instructions may include machine language code such as that created by a compiler, as well as high-level language code that can be executed by a computer using an interpreter, etc. The above-described hardware device may be configured to operate with at least one software module to perform the operations of the present invention, and vice versa.

Additionally, the above-described method or device may be implemented by combining all or part of its components or functions, or may be implemented separately.

Although the present invention has been described above with reference to preferred embodiments, those skilled in the art may make various modifications and changes to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. You will understand that you can do it.
