The embodiments may be implemented in various types of products such as personal computers, laptop computers, tablet computers, smart phones, televisions, smart home appliances, intelligent vehicles, kiosks, and wearable devices.

1 is a diagram schematically showing the configuration of a system according to an embodiment.

Referring to FIG. 1, a system according to an embodiment includes a plurality of creator terminals 4, a plurality of player terminals 5, a plurality of buyer terminals 6, a plurality of seller terminals 7, and one or more management servers. It includes (1), database 3 and file server 2, and can be connected to a pre-established Main Net.

Creator terminal (4), player terminal (5), buyer terminal (6), and seller terminal (7) are creators (users who create sound content), players (users who play sound content), and buyers (sound source users), respectively. It may refer to a smart device, PC, etc. owned by a user who purchases/purchased content (NFT) and a seller (user who sells/sold sound source content (NFT)), and any one terminal is a creator terminal (4 ), a frequent play terminal, a buyer terminal 6, and a seller terminal 7, may perform one or more roles/functions.

For example, a creator uses his/her smart device as a creator terminal (4) to convert his/her content into an NFT, and later uses the smart device as a seller terminal (7) to sell his own NFT. Then, it can be used as a buyer terminal 6 to purchase other NFTs or used as a player terminal 5 to play content created by other creators.

In one embodiment, the mainnet may correspond to the Ethereum network.

According to one embodiment, the management server 1 receives a registration request for the first content data from the creator terminal 4 (S100); may include.

The creator uploads the original file of a predetermined creation, such as a sound source (music file, sheet music file), from the app installed on his/her creator terminal (4) or from the web page/web app accessed from the web browser, and registers to turn the file into an NFT. A request message may be transmitted to the management server 1 .

The registration request message may be transmitted and received in a GET method or a POST method in the HTTP/HTTPS protocol of a web-based application.

The following steps will be described under the assumption that the registration request has been normally approved and processed.

Text information such as creator information, content title, playback time, and creation date may be stored directly in the database 3 (database server) or in the management server 1 due to its small capacity, but music files, sheet music images, Contents such as music score files (files edited with a music score editing program) have a relatively large capacity, so problems may occur in the maintenance/repair process when stored in the database 3 or the management server 1.

In addition, if you want to store the original file in the blockchain, a lot of time and cost (gas cost) will be incurred for storage, so the file server (2), management server (1), and database (3) are individually operated It is desirable to be connected to the net.

Therefore, according to the step (S200) of storing the first content data received by the management server 1 in the file server 2; the original file of the content via the management server 1 is a separate file server ( 2) is preferred.

The metadata of the original file of the content stored in the file server 2 and/or the path within the file server 2 may be used as a 'first unique identifier of the first content data' to be described later.

Generating a first non-fungible token (NFT) in which a first unique identifier of the first content data and first unique information of a first creator are recorded on a first blockchain (S300); Through, by including the location of the original file of the content and the first unique information of the first creator (identification information such as the creator's name, email, unique code (ID), electronic signature) in the first non-fungible token, the content is When used in a music streaming platform, etc., it is possible to prove who the creator of the content is.

Since the creator information for each content is recorded in the distributed ledger as described above and cannot be falsified, consumers who encounter content such as music can trust the creator information of the content.

Hereinafter, a method of trading non-fungible tokens registered in the above manner will be described. The management server 1 may perform the first non-fungible token registration steps as described above, and may independently and simultaneously perform the first non-fungible token trading steps to be described later.

In the step (S400) of the management server 1 receiving the first playback history of the first content data from the player terminal 5 (S400); It is possible to receive data of (including the number of times of playback and the number of views of sheet music) from the individual player terminals 5.

Accordingly, in the step (S500) of the management server 1 recording the first playback history, the received first playback history can be synthesized to generate a real-time streaming ranking or used for calculating copyright fees.

Here, the first reproduction history may be dually recorded in each of the blockchain and the database 3, and this dual recording process will be described later.

In addition, the first content data may include predetermined first sheet music data.

Alternatively, the first content data may further include: including predetermined first music file data, and extracting predetermined first music score data based on the first music file data. However, detailed descriptions of artificial intelligence algorithms for extracting sheet music from music files are omitted in order not to obscure the gist of the invention.

The step of generating the first non-fungible token on the first blockchain (S300) includes: encoding the first sheet music data by the management server 1 to generate second content data; and generating the first identifier by the management server 1 inputting the second content data into a predetermined hash function.

Here, in one embodiment, the first content data (metadata of the first content data, etc.) is not directly input into the hash function, but is input through the conversion process as described above, thereby undergoing predetermined standardization.

Accordingly, counterfeit/copied content in which only the original content and the metadata of the file are partially changed through a predetermined modulation has the same first identifier as the original content, and thus registration of overlapping content can be prevented.

The step of generating the second content data includes: assigning, by the management server 1, a first code number for each type of clef, key signature, time signature, musical note, and comma (S311); The management server 1 recognizing clefs, key signatures, time signatures, musical notes, and commas from the first sheet music data, and generating a predetermined second code number composed of the first code number (S312); Recognizing lyrics from the first sheet music data by the management server 1 and generating first lyrics data (S313); generating first character data by separating, by the management server 1, each character included in the first lyrics data (S314); generating, by the management server 1, second character data by removing overlapping characters from the first character data (S315); generating, by the management server 1, third character data by arranging the second character data in descending order based on the frequency of occurrence of the second character data in the first character data (S316); assigning, by the management server 1, a predetermined third code number to each character included in the third character data (S317); and generating, by the management server 1, a fourth code number by replacing each letter included in the first lyrics data with the third code number (S318).

In one embodiment, by separately encoding the music part and the lyrics part from each other, it is possible to prevent plagiarism content registration when only a part of music (including pitch, scale, etc.) or lyrics is plagiarized.

The processes of generating the second code number and the fourth code number will be described in detail in an embodiment to be described later.

Generating the first identifier may include: generating a first hash value by the management server 1 inputting the second code number into the hash function; generating, by the management server 1, a second hash value by inputting the fourth code number to the hash function; and designating, by the management server 1, the first identifier based on the first hash value and the second hash value.

In the step of designating the first identifier based on the first hash value and the second hash value, the step of verifying whether each of the first hash value and the second hash value has been previously registered; can be included To this end, the first hash value, the second hash value and the first identifier value of the first non-fungible tokens may all be recorded in the database 3 .

The first identifier may be in the form of simply joining the first hash value and the second hash value, or in the form of extracting a new hash value by applying a hash function to the joined string again.

In the process of recognizing the clef, key signature, time signature, note, and comma, a predetermined artificial intelligence (artificial neural network) model or/and algorithm (OCR (optical character recognition) technology, etc.) may be applied.

An artificial intelligence (AI) system is a computer system that implements human-level intelligence, and unlike existing rule-based smart systems, machines learn and judge on their own. The more AI systems are used, the higher the recognition rate and the more accurate understanding of user preferences. Conventional rule-based smart systems are gradually being replaced by deep learning-based AI systems.

Artificial intelligence technology consists of machine learning and element technologies using machine learning. Machine learning is an algorithm technology that classifies/learns the characteristics of input data by itself, and element technology is a technology that uses machine learning algorithms such as deep learning to mimic functions such as recognition and judgment of the human brain. It consists of technical fields such as understanding, inference/prediction, knowledge expression, and motion control.

The various fields where artificial intelligence technology is applied are as follows. Linguistic understanding is a technology for recognizing and applying/processing human language/characters, including natural language processing, machine translation, dialogue systems, question and answering, voice recognition/synthesis, and the like. Visual understanding is a technology for recognizing and processing objects like human vision, and includes object recognition, object tracking, image search, person recognition, scene understanding, space understanding, image improvement, and the like. Inference prediction is a technique of reasoning and predicting logically by judging information, and includes knowledge/probability-based reasoning, optimization prediction, preference-based planning, and recommendation. Knowledge expression is a technology that automatically processes human experience information into knowledge data, and includes knowledge construction (data creation/classification) and knowledge management (data utilization). Motion control is a technology for controlling the autonomous driving of a vehicle and the movement of a robot, and includes motion control (navigation, collision, driving), manipulation control (action control), and the like.

In general, in order to apply machine learning algorithms to real life, learning is performed in a trial and error method due to the nature of the basic methodology of machine learning. In particular, deep learning requires hundreds of thousands of iterations. It is impossible to execute this in an actual physical external environment, so instead, the actual physical external environment is virtually implemented on a computer and learning is performed through simulation.

In the step of generating the first non-fungible token on the first blockchain (S300), the management server 1 converts the fungible token in which the first identifier of the first non-fungible token is recorded into a second block. It may further include; generating on a chain.

The fungible token is used for managing the above-described first reproduction history, and the first reproduction history may be recorded in a transaction form. One or more of these fungible tokens may be provided to correspond to each of the first non-fungible tokens.

The step of receiving the first playback history (S400) is: the management server 1 receives the second playback history received in real time when the first content data is reproduced in the player terminal 5. step; recording, by the management server 1, the second reproduction history in a predetermined database 3; and recording, by the management server 1, a third playback history accumulated for each predetermined period based on the second playback history in the fungible token in which the first identifier of the first non-fungible token is recorded; can include

Whenever content is reproduced in the player terminal 5, a second playback history may be counted in real time and received by the management server 1. At this time, the counted second playback history indicates that the first content data is It can only be performed when playing more than an hour or a percentage. For example, in the case of song content with a playback time of 3 minutes, the second playback history may be counted in such a way that the second playback history is increased by 1 when playback is performed for about 1 minute and 30 seconds.

In the above description, the predetermined period may be a period of about 1 week to 1 month to reduce the block chain processing load, which may be set by an administrator. Since the third reproduction history is collected and recorded to be used for distribution of copyright fees, etc., unlike the second reproduction history, it does not necessarily need to be collected in real time.

In addition, the step of generating the second content data includes: a step in which the management server 1 searches for third content data in which a second non-fungible token is registered by a second creator (S321); Extracting, by the management server 1, fifth code numbers generated based on clefs, key signatures, time signatures, notes, and commas from the third content data, and sixth code numbers generated based on lyrics ( S322); Comparing, by the management server 1, the second code number and the fourth code number with the fifth code numbers and the sixth code numbers to calculate a similarity rate (S323); When the management server 1 has a third content data corresponding to a fifth code number or a sixth code number having a similarity rate equal to or greater than a predetermined first rate, a message indicating that the registration of the first content data is not possible and the above Transmitting third content data to the creator terminal 4 (S324); marking third content data corresponding to a fifth code number or a sixth code number having a similarity rate equal to or greater than a predetermined second rate on the creator's terminal (4) (S325); Generating, by the management server 1, the [first hash value] only for the [first content data where the [-the fifth code number or the sixth code number whose similarity rate is greater than or equal to the first ratio] does not exist] , generating a second hash value and designating a first identifier] (plagiarism verification step (S326)); And the management server 1 for [the first content data in which the fifth code number or the sixth code number having the similarity rate is less than the first rate and the second rate or more exists], [the fifth code number or and recording the first identifier as a lower non-fungible token in the second non-fungible token of the third content data corresponding to the sixth code number (S327).

In the above description, the second creator may refer to other creators who have already registered content data (third content data, second non-fungible token) based on the point in time when the first creator intends to register the first content data.

The management server 1 calculates the similarity rate by comparing the first content data with the previously registered third content data, and if the similarity rate is very high, it is determined to be plagiarism (for example, if the similarity rate is 70% or more) ), registration is rejected, and if the similarity rate is higher than a predetermined value and it is determined that the content of the existing music content is cited (for example, if the similarity rate is 30% or more and less than 70%), registration is refused, but the original music content It can be recorded as a sub-non-fungible token and a part of the proceeds can be settled to the right holder of the existing music content when the revenue is distributed.

At this time, by comparing the music part and the lyrics part between the first content data and the third content data, respectively (comparing the second code number and the fifth code number, comparing the fourth code number and the sixth code number), the music part right holder Even if the owner of the lyrics part or the similarity rate is different from that of the lyrics part, it can be set to distribute the proceeds in consideration of this.

The NFT-based sound source reproduction and creation history management platform service providing method comprises: calculating, by the management server 1, proceeds from the first non-fungible token; The management server 1 includes a first part of the proceeds of the first non-fungible token recorded as a lower non-fungible token of the second non-fungible token in the proceeds of the second non-fungible token, so that the second non-fungible token Calculating the proceeds of; Step of the management server (1) payment processing of the second part excluding the first part from the proceeds of the first non-fungible token; and processing, by the management server 1, payment of the proceeds of the second non-fungible token.

In addition, the first code number is composed of a string in which an individual code is a combination of 1 letter of the alphabet and 1 to 3 letters of a number, the clef is a combination of the alphabet 'A' and 1 letter of the number, and the key table is an alphabet The time signature is a combination of 'B' and 3 numbers, the time signature is a combination of 'C' and 3 numbers, the note is a combination of 'D' and 3 numbers, and the comma is a combination of 'E' and 3 numbers It is composed of a combination of 1 letter, and 1 letter of the number of the clef is designated as a predetermined numbering according to the type of the clef, and among the 3 letters of the number of the key, the first letter is a predetermined numbering according to the type of key, The next 2 letters are designated by a predetermined numbering according to the note in which the key signature is placed, and among the 3 letters of the time signature, the first 2 letters are natural numbers corresponding to the numerator of the time signature, and the next 1 letter corresponds to the denominator of the time signature. It is designated as the n value when the number is expressed as 2 to the nth power, and among the 3 letters of the number of the note, the first letter is the m value when the note beat is expressed as 2 to the -m power, and the next 2 letters is designated as a predetermined numbering according to the clef in which the note is placed, and one letter of the number of the comma may be designated as a k value when the time signature of the comma is represented by 2 to the -k power.

Hereinafter, the first code number will be described as an example.

The treble clef can be represented by A1 and the bass clef by A2.

The key table may be used by specifying raised marks, flat marks, natural marks, raised marks, double lower marks, etc. as 1 to 5 times, respectively, and two-digit numbers may be further combined based on the reference position. For example, when the 'first degree' scale position is 00 as a standard, the first code number in the case of 'G major' with a round mark placed at the 'second wave' scale position can be expressed as B110 .

The time signature can be expressed in the form of C042 (C 04 2) in the case of 4/4 time signature, and in the form of C083 (C 08 3) in the case of 8/8 time signature.

When the note is based on the 'first degree' scale position of 00, the '16th note' marked at the 'first degree' scale position can be expressed as D400, and the 'whole note' marked at the 'first wave' scale position can be expressed as D004 .

In the case of a comma, there is no separate musical scale, so a whole rest can be expressed as E0, a 16th rest can be expressed as E4, etc.

An example of the second code number is as follows.

A1B110C083D003D403D203E0E4 = Treble clef, G major, 8/8 time, whole note 'me', 16th note 'me', quarter note 'me', whole rest, 16th rest

The step of calculating the similarity rate (S323) includes: the management server 1 designating 10 or more consecutively arranged first code numbers as a predetermined seventh code number from the second code numbers; Inquiring, by the management server 1, whether there is a part identical to the seventh code number among the fifth code numbers; and designating [the number of seventh code numbers having a part identical to the fifth code numbers / the total number of the seventh code numbers] as a similarity rate with respect to the second code number. there is.

Second code numbers constituting certain first content data reach hundreds of digits, and a similarity rate can be calculated by extracting a combination of first code numbers, which is a part of them, and comparing them.

At this time, by parsing the second code number based on each alphabet, as many first code numbers as desired can be extracted.

For example, extracting 15 first code numbers from the front from the second code number is extracted as a seventh code number, and whether there is a part matching the seventh code number in the fifth code number, the fifth code number The whole and the seventh code number can be compared. At this time, if the number of first code numbers included in the second code number is 300, 20 seventh code numbers are generated and the comparison process may be performed 20 times.

According to one embodiment, the management server 1 receives a registration request for the first content data from the creator terminal 4 (S100); Storing the first content data received by the management server 1 in a file server 2 (S200); A first non-fungible token in which the management server 1 uses a smart contract to record the registration date of the first content data, the first unique identifier of the first content data, and the first unique information of the first creator ( Generating a Non-Fungible Token (NFT) on a first blockchain (S300); receiving, by the management server 1, a first reproduction history of the first content data from the player terminal 5 (S400); Recording, by the management server 1, the first reproduction history (S500); Displaying a list of the first non-fungible tokens registered on the first blockchain in the purchaser terminal 6 (S600); When any one of the first non-fungible tokens is selected in the purchaser terminal 6, displaying a list of lower non-fungible tokens of the selected first non-fungible token on the purchaser terminal 6 (S700); Receiving, by the management server 1, a purchase request for the first non-fungible token from the purchaser terminal 6 (S800); The management server 1 transmitting the purchase request to the seller terminal 7 (S900); Receiving, by the management server 1, whether or not to approve the purchase request (including approval decision and approval rejection) from the seller terminal 7 (S1000); When the approval decision is received by the management server 1, transmitting the first non-fungible token to a buyer's address (S1100); And the step of the management server (1) recording the transfer history of the first non-fungible token from the seller's address to the buyer's address in the first blockchain (S1200); including, blockchain-based content of NFT and provide a method for providing NFT trading platform services.

Receiving, by the management server 1, a purchase request for some of the plurality of first non-fungible tokens from the purchaser terminal 6 (S800); For one or more contents selected in , when the purchase request button is operated to purchase the first non-fungible token corresponding to each content, it is transmitted from the purchaser terminal 6 to the management server 1.

In the above description, 'some of the plurality of first non-fungible tokens' means any one or more of the plurality of first non-fungible tokens registered by the plurality of creators. Accordingly, the purchaser may request purchase of one or more first non-fungible tokens one by one or all at once.

In accordance with the step (S900) of the management server 1 transmitting the purchase request to the seller terminal 7, a purchase request message is sent to the seller terminal 7 of each owner of the first non-fungible tokens requested for purchase. It is passed on.

The seller terminal 7 generates a predetermined push notification to confirm that the purchase request message for the first non-fungible token owned by the seller has been received.

The seller may check the bid price recorded in the purchase request message, and may approve or reject the purchase request based on this.

The first non-fungible token, which is newly generated and not transacted (transacted) to another user, performs the functions of the creator terminal 4 and the seller terminal 7. After the creator sells the first non-fungible token to other users, the buyer of the first non-fungible token acts as a seller to the other users.

Receiving, by the management server 1, whether or not to approve the purchase request (including approval decision and rejection of approval) from the seller terminal 7 (S1000); when the seller approves the purchase request, the corresponding It may include a process of determining whether a transaction is appropriate and processing the transaction.

Transmitting (Transaction) the first non-fungible token to the buyer's address when the approval decision is received by the management server (1) (S1100); and recording the transfer history of the first non-fungible token from the seller's address to the buyer's address in the block chain (S1200); 'address' may mean an electronic wallet address.

The transaction process as described above may be performed by an exchange in a state where the non-fungible token is listed on the exchange server.

In addition, the step of marking the list of lower non-fungible tokens on the purchaser terminal 6 includes: receiving, by the management server 1, information on fourth content data corresponding to the lower non-fungible token; Calculating, by the management server 1, the proceeds of the sub-non-fungible token; Calculating, by the management server 1, the proceeds of the first non-fungible token by including a first part of the proceeds of the lower non-fungible token in the proceeds of the first non-fungible token; and displaying the proceeds of the first non-fungible token and the proceeds of the lower non-fungible token in the purchaser terminal 6.

For example, when calculating the proceeds for song A of 'Hong Gil-dong', the original composer, the proceeds for song B of 'Chul-Soo Kim', which partially quotes (7%) of the song A, can be calculated simultaneously. When the proceeds of the song B are 1 million won, the proceeds of about 70,000 won may be reflected in the proceeds of the song A by referring to a predetermined rate table based on the ratio to the quoted part. Therefore, if the proceeds generated by the song A itself were 500,000 won, the final proceeds of the song A may be 570,000 won.

And, based on the first content data reproduced by the player terminal 5, the management server 1 recommends a predetermined fifth content data to the player terminal 5; , Receiving the first reproduction history (S400) includes: in the management server 1, querying a predetermined eighth code number registered in the database 3; And generating, by the player terminal 5, a ninth code number that is a third part of the second code number reproduced from the first content data and transmitting it to the management server 1, The step of recording the first playback history (S500) includes: the management server 1 inquiring whether there is a part identical to the eighth code number in the ninth code number; and adding, by the management server 1, the number of plays for the eighth code having a matching part in the ninth code number, wherein the recommending the fifth content data includes: the management server (1) generating a sixth content data list including the eighth code number having a matching part in the ninth code number; and arranging, by the management server 1, the sixth content data list in descending order of the reproduction number of the eighth code number, and designating the sixth content data recorded with the highest reproduction number as the fifth content data. ; can be included.
