Description

Technical Field

[0001] The present invention relates to a method and system for providing digital items based on NFT. More specifically, it relates to a method and system for providing digital items based on NFT that adjusts the quiz difficulty to adjust the gacha success probability.

Background Art

[0002] Fandom refers to people or groups who passionately like, immerse themselves in, and get deeply involved in a specific person (especially artists, etc.) or field. Such fandom culture has evolved into a new industry that creates new economic value while spreading across various fields.

[0003] For example, various digital goods for each artist supported by each fandom, such as digital photo cards, can be provided to fans (users) in a way such as probability-based items provided in online game services. They are classified into high-class, middle-class, and low-class according to quality and rarity, etc., and can be provided to fans by means such as gacha (prize draw). Fans can improve their grades by using methods such as synthesizing and strengthening the provided digital items.

[0004] On the other hand, recently, regulations have been added to provide gacha services without disclosing the gacha probability, such as the introduction of the "Probability-Type Item Regulation Act", etc., and the composition ratio, types of obtainable items, the probability of an item appearing, etc. are made explicit.

[0005] However, since the explicitly stated probability is provided unilaterally by the site providing the service, the possibility of the provider manipulating the probability still exists.

[0006] In addition, since the items obtained through item synthesis are random items that do not reflect the user's selection, in the case of fans who support a specific artist, if the artist they support does not appear, there is a problem that their satisfaction level drops significantly.

[0007] On the other hand, in recent years, with the epoch-making development of blockchain technology, the utilization of NFTs (Non-Fungible Tokens) based on this has been expanding in various fields.

[0008] Here, the NFT means a virtual token that uses blockchain technology to prove the owner of digital assets.

[0009] Specifically, the NFT can be a kind of virtual authenticity certificate used to represent its unique originality and ownership by putting the address pointing to digital files such as a predetermined image, picture, and / or audio into the token.

[0010] That is, the NFT can mean a unique digital file form registered on the blockchain, and such an NFT has the advantage that its economic value can gradually increase as time goes by, and the interest in the NFT is also gradually increasing.

For example, the sizes and thicknesses of each configuration shown in the drawings are arbitrarily shown for convenience of explanation, so the present invention is not necessarily limited to the places shown in the drawings.

[0036] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When explaining with reference to the drawings, the same or corresponding components are given the same drawing reference numerals, and duplicate explanations thereof are omitted.

[0037] FIG. 1 is a conceptual diagram of a digital item providing system based on NFT according to an embodiment of the present invention.

[0038] As shown in FIG. 1, a digital item providing system based on NFT according to an embodiment of the present invention (hereinafter referred to as the digital item providing system) can provide a service (hereinafter referred to as the digital item providing service) that presents a predetermined quiz with difficulty adjusted based on the rarity / grade of the digital item when conducting a lottery, enhancement, and synthesis of digital items to which NFT is applied, and provides digital items only to users who answer the quiz correctly.

[0039] The digital item providing system according to an embodiment of the present invention can provide digital items, which are goods for each artist digitized by issuing digital items with unique values assigned via a blockchain for each good of each artist.

[0040] The digital item is a product that includes predetermined content produced in a digital format such as characters, sounds, images, and pictures, and in the embodiment, can mean digital content related to an artist (for example, digital photo cards, etc.).

[0041] In the embodiment, NFT can be applied to the digital item, and thus it can become an object of transaction with cryptocurrency and can be purchased / transacted / exchanged on a cryptocurrency exchange for each fan to collect and store.

[0042] At this time, the digital items can be enhanced and synthesized with each other in order to improve their quality, such as collecting digital items with high rarity or adding predetermined content to the digital items in storage.

[0043] Also, in an embodiment, the digital item can be first provided to a user via at least one of a designated and a random lottery method.

[0044] In an embodiment, such a digital item can include NFT media data, NFT metadata, and NFT smart contract data.

[0045] NFT media data is original data, meaning the content itself including characters, sounds, images, and pictures related to an artist.

[0046] Also, NFT metadata is data related to the original data, including explanatory information, generator information, and storage address information, etc.

[0047] Also, NFT smart contract data is data related to the digital item as an asset, including owner information, transaction history information, condition information, and price information, etc.

[0048] In an embodiment, for such a digital item, the price information included in the NFT smart contract data can be varied according to the rarity of the content of the NFT media data included in the digital item, and the asset value of the digital item can be determined.

[0049] Therefore, in an embodiment, for digital items, a grade based on rarity can be preset for each digital item.

[0050] The grade of the digital item can be assigned with numbers, alphabets, star ratings, etc. The administrator can determine the grade based on its rarity and pre-match the grade for each digital item. At this time, the rarer the digital item, the higher the grade can be.

[0051] For example, digital photo cards of multiple types of A artists can have grades such as C grade / B grade / A grade / S grade / SS grade, etc. pre-matched according to their rarity.

[0052] In an embodiment, it is possible to assist in the synthesis between digital items and provide a digital item of a higher grade than the grade of the digital item selected as the synthesis material.

[0053] In other words, in an embodiment, it is possible to assist in the synthesis between digital items and replace the digital item selected as the synthesis material with a more rare digital item for provision.

[0054] Also, in an embodiment, the grade of the digital item can be improved according to the quantity and quality of the content of the NFT media data included in the digital item, and the asset value of the digital item can be increased.

[0055] For this purpose, in an embodiment, it is possible to add predetermined content to the NFT media data included in the digital item through enhancement and upgrade, or improve the quality of the existing content.

[0056] For example, by performing enhancement and upgrade on the digital photo card of A artist, content such as effect, album name text, audio file of the artist's sound source, and handwritten signature image can be added to the NFT media data, or the resolution of the photos and images included in the NFT media data can be increased, or the playback length of the audio file of the sound source can be lengthened.

[0057] That is, the higher the grade of the digital item, the more the quantity of the content included in the digital item can be increased or the quality can be improved.

[0058] On the one hand, when drawing lots / enhancing / synthesizing digital items according to an embodiment of the present invention, a predetermined quiz with a difficulty level adjusted based on the grade of the pre-matched digital item can be presented.

[0059] In addition, for digital items that can be obtained by the user through drawing lots / enhancing / synthesizing, if the user requests to obtain a digital item, a quiz will be presented to the user, and it can be provided to the user when the user answers the presented quiz correctly.

[0060] For example, when the grade of the digital item that the user can obtain is low, a quiz with a low difficulty level may be presented, and the probability that the user obtains the digital item may be high. When the grade of the digital item that the user can obtain is high, a quiz with a high difficulty level may be presented, and the probability that the user obtains the digital item may be low.

[0061] In an embodiment, a digital item providing system that provides the above digital item providing service can include a user terminal 100, a digital item providing service server 200, an NFT service server 300, and a network 10 (Network).

[0062] At this time, the user terminal 100, the digital item providing service server 200, and the NFT service providing server 300 can be connected via the network 10.

[0063] Here, the network 10 according to the embodiment means a connection structure in which information can be exchanged between respective nodes such as the user terminal 100, the digital item providing service server 200, and / or the NFT service providing server 300.

[0126] For this purpose, the quiz generation module 210 can generate at least one or more quiz data based on predetermined artist information data (in the embodiment, a photo, image, voice, sound source, and detailed information of the artist, etc.) included in the artist information database 250.

[0127] In the embodiment, the artist information data can mean various information about the artist who is the subject of the quiz. For example, it can include content such as a photo, image, voice, and sound source of the artist included in the quiz, and a profile (Profile) including the artist's hometown, education background, and debut date, etc.

[0128] Hereinafter, the quiz data before the difficulty is determined is new quiz data, and the quiz data whose difficulty is determined by a plurality of users solving the new quiz data a predetermined number of times or more (for example, 100 times or more, etc.) can be referred to as reference quiz data.

[0129] In an embodiment, the new quiz data can include an artist name and / or an artist group name, artist information data, a question generation date, a question type (e.g., image / audio / image / text, etc.), and question data, an answer type (e.g., objective / subjective, etc.) and answer data, a correct answer rate, and a difficulty level, etc.

[0130] At this time, the correct answer rate and the difficulty level can be determined after at least one or more users have solved the generated new quiz data, and in the new quiz data before the users solve it, it can be a default value (e.g., 0).

[0131] Also, in an embodiment, the quiz generation module 210 can extract at least one or more artist information data pre-stored in the artist information database 250.

[0132] At this time, the extracted artist information data can be the source of the quiz data generated by the quiz generation module 210 in the embodiment.

[0133] Also, in an embodiment, the quiz generation module 210 can generate at least one or more new quiz data based on user inputs for respectively inputting and / or selecting an artist name and / or an artist group name, a question generation date, a question type (e.g., image / audio / image / text, etc.), and an answer type (e.g., objective / subjective, etc.) for the extracted artist information data.

[0134] The entity that generates new quiz data based on the user input can be an administrator and / or a user (hereinafter referred to as a user) of the user terminal 100 provided with a fan platform application.

[0135] At this time, the new quiz data directly participated by the user and generated based on the user's input can be stored in the question bank database 240 after passing through an inspection procedure by an administrator or the like.

[0136] For example, based on the information data of Artist A included in the artist information database 250, the quiz generation module 210 can generate new quiz data for guessing which artist it is by exposing only a part (e.g., hair, hands, clothes, etc.) of the image and picture of Artist A.

[0137] Also, for example, based on the information data of Artist A included in the artist information database 250, the quiz generation module 210 can generate new quiz data for guessing which artist it is by playing only a part (e.g., 1 second of the sound source introduction part) of the voice and sound source of Artist A.

[0138] Also, for example, based on the information data of Artist A included in the artist information database 250, the quiz generation module 210 can generate new quiz data for guessing the birthday, record release date, debut date, and preferences, etc. of Artist A by revealing Artist A.

[0139] That is, in the embodiment, such a quiz generation module 210 can generate at least one or more new quiz data based on the inputs of the administrator and the user and store them in the question bank database 240.

[0140] At least one or more new quiz data generated by the quiz generation module 210 and stored in the question bank database 240 can be used in a mock test that is a quiz for determining difficulty level.

[0141] Also, in the embodiment, the difficulty management module 220 can determine the difficulty level of at least one or more new quiz data stored in the question bank database 240.

[0142] For example, the difficulty level can be represented by a number from 0 to 100, where the higher the number, the higher the difficulty level. It can also be classified and represented into predetermined classes, such as very easy / easy / normal / difficult / very difficult, etc.

[0143] For this reason, in the embodiment, at least one or more new quiz data stored in the question bank database 240 can be presented in the simulation test.

[0144] As a result, at least one or more users can take a simulation test based on the fan platform application stored in the user terminal 100 and solve at least one or more new quiz data.

[0145] In the embodiment, the difficulty management module 220 can calculate the correct answer rate of each new quiz data presented in the simulation test by the user, and determine the difficulty level of the new quiz data based on the correct answer rate.

[0146] That is, in the embodiment, the difficulty management module 220 can determine the difficulty level of at least one or more new quiz data stored in the question bank database 240 based on the correct answer rate of the users who solved the predetermined new quiz data based on the simulation test.

[0147] As a result, in the embodiment, the difficulty management module 220 can construct the question bank database 240 by converting the new quiz data with the determined difficulty level into reference quiz data and storing it.

[0148] At least one or more reference quiz data stored in such a question bank database 240 can be presented in a practical test, which is a quiz presented when a user attempts to obtain a digital item through lottery or synthesis, or attempts to upgrade a digital item through enhancement, in the fan platform application according to the embodiment.

[0149] In the embodiment, the new quiz data and reference quiz data presented in the simulation test and the actual combat test only differ in whether they are before or after the difficulty is determined, can include the same quiz content, and only the predetermined data included in the quiz content can be changed by adjusting the difficulty.

[0150] Also, in the embodiment, the difficulty management module 220 can manage the difficulty of at least one or more reference quiz data.

[0151] In the embodiment, the reference quiz data can further include a digital item payment rate in addition to the artist name and / or artist group name, artist information data, question generation date, question type, question data, answer type, answer data, correct answer rate, and difficulty.

[0152] In the embodiment, the digital item payment rate can be a value indicating the ratio of the number of digital item payments due to the user's correct answers to the number of questions asked.

[0153] Specifically, in the embodiment, the difficulty management module 220 can adjust the difficulty by changing the predetermined data included in at least one or more reference quiz data based on the digital item payment rate of the user.

[0154] For this purpose, in the embodiment, when the digital item payment rate exceeds a preset standard, the difficulty management module 220 determines that the questions are frequently asked and the probability of the user getting the correct answer has increased, and can change the predetermined data included in the reference quiz data.

[0155] Specifically, in the embodiment, the difficulty management module 220 can adjust the difficulty of the first reference quiz data by changing the exposure range and / or answer type of the artist information data included in the first reference quiz data whose digital item payment rate exceeds a preset standard.

[0156] Also, in an embodiment, the digital item management module 230 can add the number of contents included in the digital item or improve the quality according to the enhancement result of the digital item.

[0157] Also, in an embodiment, the digital item management module 230 can replace a digital item owned by a user with another digital item according to the synthesis result of the digital item.

[0158] Also, in an embodiment, the digital item management module 230 can, in conjunction with the external server 300, trade (for example, purchase / sell / exchange, etc.) a predetermined digital item having a value as a cryptocurrency.

[0159] Also, in an embodiment, the problem bank database 240 can store and manage at least one or more quiz data and the like.

[0160] Specifically, in an embodiment, the problem bank database 240 can classify and store and manage at least one or more quiz data (in an embodiment, new quiz data and reference quiz data) according to a predetermined criterion (for example, by individual artist, group, difficulty level, etc.).

[0161] At this time, at least one or more reference quiz data included in the problem bank database 240 in an embodiment can be sorted in ascending order of difficulty. Thereby, the upper percentage of the sorted difficulty level can be set, and only the reference quiz data including the difficulty level within the corresponding range can be extracted, and a detailed description thereof will be described later.

[0162] Also, in an embodiment, the artist information database 250 can store and manage at least one or more artist information data and the like.

[0163] Specifically, in the embodiment, the artist information database 250 can store and manage at least one or more pieces of artist information data according to a predetermined criterion (for example, by individual artist, by group, etc.).

[0164] Also, in the embodiment, the digital item database 260 can store and manage at least one or more digital items.

[0165] Also, in the embodiment, the digital item database 260 can store and manage digital item content that serves as a source for producing digital items (for example, photos and images for making digital photo cards, handwritten character images, artist voice audio files, etc.).

[0166] Specifically, in the embodiment, the digital item database 260 can store and manage at least one or more digital items and digital item content according to a predetermined criterion (for example, by individual artist, by group, by grade, etc.).

[0167] Also, in the embodiment, the problem bank database 240, the artist information database 250, and the digital item database 260 can store and manage various application programs, applications, command words, and / or data, etc. for realizing the digital item providing service.

[0168] On the other hand, the service server 200 including the above-described components and the like can realize the digital item providing service by exchanging data necessary for driving the digital item providing process with an external device such as the user terminal 100.

[0169] More specifically, in the embodiment, the service server 200 can provide an environment in which the application 111 can operate on an external device (in the embodiment, the mobile type computing device 100-1 and / or the desktop type computing device 100-2, etc.).

[0170] For this purpose, the service server 200 can include an application program, data, and / or instruction words for the operation of the application 111, and can transmit and receive various data based on this to and from the external device.

[0171] Also, in the embodiment, the service server 200 can store and manage various application programs, instruction words, and / or data for realizing the digital item providing service.

[0172] As an embodiment, the service server 200 can store and manage at least one or more quiz data, artist information data, and / or user interface, etc.

Thus, various embodiments are possible.

[0186] · External Server 300

[0187] On the other hand, the external server 300 according to the embodiment of the present invention can provide predetermined data that can be utilized in the digital item providing service to the user terminal 100 and / or the service server 200.

[0188] Specifically, in the embodiment, the external server 300 may be a server that realizes an external service that can support transactions of digital items (in the embodiment, purchase and sale of artist-related digital items for various fan bases that support artists and artist groups, etc.) based on a fan platform application.

[0198] · A method for constructing a question bank database by performing simulation tests

[0199] Hereinafter, with reference to FIGS. 4 to 5 attached, a method for constructing a question bank database 240 by an application 111 executed by at least one or more processors of the user terminal 100 according to an embodiment of the present invention performing a simulation test based on a fan platform application will be described in detail.

[0200] In an embodiment of the present invention, at least one or more processors of the user terminal 100 can execute at least one or more applications 111 stored in at least one or more memories 110 or operate in a background state.

[0201] Hereinafter, it will be briefly described that the above - mentioned method of constructing the question bank database 240 is performed by the application 111 operating to execute the instruction words of the application 111 by the at least one or more processors.

[0202] FIG. 4 is a flowchart for explaining a method for constructing a question bank database according to an embodiment of the present invention.

[0203] As shown in FIG. 4, in the embodiment, the application 111 can execute a simulation test. (S101)

[0204] Specifically, in the embodiment, the application 111 senses the input of a user who selects individual artists and groups, and thereby can execute a simulation test related to the selected individual artists and groups.

[0205] Also, in other embodiments, the application 111 extracts the user's joined fan club information, automatically selects individual artists and groups corresponding to the fan club, and can execute a simulation test related to the selected individual artists and groups.

[0206] At this time, in the embodiment, the simulation test can be executed based on at least one or more new quiz data generated in advance by an administrator or / and a user.

[0207] Also, in the embodiment, the simulation test is a procedure that a plurality of users who use the fan platform application 111 must / periodically execute in order to verify the difficulty appropriateness of at least one or more quiz data stored in the question bank database 240 (specifically, determining the difficulty of new quiz data and adjusting the difficulty of reference quiz data in the embodiment).

[0208] Thereby, in the embodiment, the application 111 can set conditions such as providing a predetermined reward (for example, awarding fan points, concert ticket application circles, coupons, discount coupons, etc.) to the user who conducts the simulation test, or granting the qualification to conduct a live test only to the user who has conducted the simulation test a predetermined number of times or more.

[0209] Also, in the embodiment, the application 111 can recruit at least one or more users who execute a simulation test related to a specific artist.

[0210] This is because the difficulty level of the new quiz data stored in the question bank database 240 can be determined and converted and / or stored as reference quiz data only after the new quiz data has been solved by a plurality of users more than a predetermined number of times set in advance. Therefore, it is for presenting the new quiz data of the artist who has not satisfied the predetermined number of times set in advance.

[0211] In an embodiment, the application 111 can provide additional rewards to the users who have executed the mock test for the specific artist solicited.

[0212] Next, in an embodiment, the application 111 can extract and present new quiz data from the question bank database 240. (S103)

[0213] Specifically, in an embodiment, the application 111 can randomly extract and present predetermined new quiz data related to the artist selected through step S101 from the question bank database 240.

[0214] At this time, each of the new quiz data includes an artist name and / or an artist group name. Thus, since the question bank database 240 is divided and stored by individual artist and / or by group, in an embodiment, the application 111 can randomly extract and present predetermined quiz data from among a plurality of new quiz data related to the artist selected in step S101.

[0215] As a result, at least one user can solve the quiz by inputting predetermined response data into the given predetermined quiz data. For example, the user can solve the quiz by selecting number 1 for a five-choice objective quiz or inputting predetermined characters and numbers for a subjective quiz based on the fan platform application 111 provided on each user terminal 100 to input response data such as this.

[0216] Next, in the embodiment, the application 111 can end the simulation test and store the result of the simulation test. (S105)

[0217] Specifically, in the embodiment, the application 111 can end the simulation test and store, for each of at least one or more new quiz data presented in the simulation test, the number of times of presentation and the result including whether it is correct or incorrect.

[0218] At this time, the number of times of presentation can be a predetermined value calculated for the new quiz data to be converted into reference quiz data, and whether each of at least one or more new quiz data presented in the simulation test is correct or incorrect can also be provided to the user terminal 100 and disclosed to the user.

[0219] The above-described steps S101 to S105 can be repeatedly performed by a plurality of users using the fan platform according to the embodiment of the present invention. As a result, the number of times of presentation of each new quiz data and whether it is correct or incorrect can be accumulated according to the number of times performed.

[0220] Next, in the embodiment, the application 111 can calculate the correct answer rate of the new quiz data based on the stored result. (S107)

[0221] Specifically, in the embodiment, the application 111 can calculate the correct answer rate of the new quiz data that satisfies a preset number of times of presentation based on the stored result.

[0222] In an embodiment, the number of questions presented is a predetermined number that must be presented at least in order to calculate objective statistics, and can be preset by an administrator. For example, the preset number of questions presented can be set to 100 times or the like.

[0223] That is, the new quiz data for which the correct answer rate is calculated in step S107 can be new quiz data that has been presented a predetermined number of times or more.

[0224] Also, the correct answer rate can be a value indicating, as a probability (%), the number of correct answer users with respect to the number of users who solved each new quiz data. For example, if the number of users who solved the quiz is 200 and among them, the number of correct answer users is 10, then 10 / 200 = 5% can be the correct answer rate.

[0225] Next, in an embodiment, the application 111 can determine the difficulty level of new quiz data based on the calculated correct answer rate. (S109)

[0226] Specifically, in an embodiment, the application 111 can determine the difficulty level of the new quiz data based on the calculated correct answer rate of each new quiz data presented in the simulation test.

[0227] For this purpose, in an embodiment of the present invention, at least one or more difficulty classes with a predetermined correct answer rate range preset can be classified.

[0228] Thereby, in an embodiment, the application 111 can determine the difficulty level of the new quiz data by deriving the difficulty class of the correct answer rate range in which the calculated correct answer rate is included.

[0229] For example, in an embodiment, there can be 1st to 10th difficulty classes, and it can be established that the difficulty level becomes more difficult from the 1st difficulty class to the 10th difficulty class.

[0230] Also, for example, the preset correct answer rate range for the first difficulty class can be 80% to 100%. On the other hand, the preset correct answer rate range for the tenth difficulty class can be 0% to 0.1%.

[0231] The above examples are merely examples for convenience of explanation, and there can be various embodiments, such as the difficulty levels being formulated in different ways, the difficulty levels being classified into classes less than or more than the tenth difficulty class, or the preset correct answer rate ranges for each class also being different.

[0232] That is, in the embodiment, the application 111 can determine the derived difficulty class as the difficulty level of the new quiz data by deriving the difficulty class corresponding to the correct answer rate range including the calculated correct answer rate.

[0233] Next, in the embodiment, the application 111 can convert the new quiz data with the determined difficulty level into reference quiz data and store it in the question bank database 240. (S111)

[0234] Specifically, in the embodiment, the application 111 can convert the new quiz data with the determined difficulty level into reference quiz data, and classify and manage the at least one or more reference quiz data according to a predetermined criterion (for example, by artist).

[0235] FIG. 5 is an example showing the reference quiz data stored in the question bank database according to the embodiment of the present invention. Specifically, FIG. 5 shows at least one or more reference quiz data for artist A. The omitted parts in the table can include data such as artist group name, artist information data, question generation date, question type, answer type, and the like.

[0236] As shown in FIG. 5, in the embodiment, the application 111 can arrange at least one or more reference quiz data for Artist A in the order from the data with a high difficulty level determined based on the correct answer rate to the data with a low difficulty level.

[0237] For example, in the embodiment, the application 111 can arrange at least one or more reference quiz data for Artist A in the order from the 10th difficulty class with a preset correct answer rate range of 0 to 0.1% to the 1st difficulty class with a preset correct answer rate range of 80 to 100%.

[0238] At this time, in the embodiment, the application 111 can arrange the data in the order from the data with a low correct answer rate (in other words, a higher difficulty level) to the data with a high correct answer rate even within the same difficulty class.

[0239] For example, the reference quiz data corresponding to serial number 2 shown in FIG. 5 belongs to the same difficulty class as the reference quiz data corresponding to serial number 3, but since the correct answer rate is lower, it can be arranged above the reference quiz data corresponding to serial number 3.

[0240] By such a method, in the embodiment, the application 111 can classify at least one or more reference quiz data for each of at least one or more artists who have joined the fan platform service, and arrange and store them in the order of difficulty level.

[0241] That is, the application 111 according to the embodiment of the present invention can perform a simulation test based on the fan platform application, and construct a question bank database 240 including at least one or more reference quiz data classified and stored according to a predetermined standard.

[0242] · Method for providing a digital item providing service based on a quiz test

[0243] The following will refer to FIGS. 6 to 9 to explain in detail a method of providing a digital item providing service in which an application 111 executed by at least one or more processors of the user terminal 100 according to an embodiment of the present invention presents a predetermined quiz (in the embodiment, a quiz test) whose difficulty is adjusted based on the rank of digital items, and provides digital items to users who answer the quiz.

[0244] In an embodiment of the present invention, at least one or more processors of the user terminal 100 can execute at least one or more applications 111 stored in at least one or more memories 110 or operate in a background state.

[0245] Hereinafter, the method by which the at least one or more processors operate to execute the instruction words of the application 111 to provide the above-described digital item providing service will be briefly described as being performed by the application 111.

[0246] Prior to the description, in the embodiment, the application 111 can obtain a new digital item through at least one of a lottery method, a synthesis method, and an enhancement method according to a user's request.

[0247] Specifically, the application 111 can pay a predetermined good, request a digital item lottery method (in the embodiment, designated and / or random), and provide a lottery function for obtaining a new digital item if the quiz test is passed.

[0248] Here, the designated lottery method is a method in which the user designates an artist who is the target of the digital item, designates the grade of the digital item to be obtained, applies for a lottery, and if the user passes the quiz test, randomly selects a digital item from among a plurality of digital items having the designated artist or / and grade as an attribute. And the random lottery method is a method in which a lottery is applied without designating an artist or grade, and if the quiz test is passed, a random digital item of an artist and grade whose attributes are randomly determined is obtained. Hereinafter, for the sake of explanation, only the designated lottery method will be described as a reference.

[0249] On the other hand, in the embodiment of the present invention, even if it is not the designated lottery method, a specific digital item can be selected and the digital item can be obtained by the designated purchase method. However, in the case of the designated purchase method, the digital item can be obtained without passing the quiz test. Therefore, the price of its use right can be sold at a higher amount than the use right of the designated lottery method.

[0250] Further, the application 111 according to the embodiment of the present invention can provide a function of obtaining a digital item upgraded from the paid digital item if at least two or more of the digital items held by the user are paid and a synthesis is requested in the synthesis method and the quiz test is passed.

[0251] In addition, the application 111 according to the embodiment of the present invention can provide a function of obtaining a digital item upgraded from the digital item that the user already holds by paying a predetermined cost (for example, goods, enhancement items, etc.) and passing the quiz test in the enhancement method.

[0252] In the case of the synthesis and enhancement methods, it is a method of replacing the grade matched to the paid digital item with one digital item whose grade has been raised from the previously matched grade and providing it. Regardless of whether the synthesis and enhancement are successful or not, the paid digital item can be incinerated.

[0253] In the case of such a synthesis and enhancement method, in terms of the fact that the paid digital item is incinerated, a limited edition digital item that cannot be obtained by the lottery method may be provided, or the maximum grade of the digital item that can be obtained by the synthesis unenhanced method may be higher than the maximum grade of the digital item that can be obtained by the lottery method, etc., and a predetermined benefit may be added.

[0254] Also, when acquiring and / or upgrading a digital item based on the lottery / synthesis / enhancement method according to the embodiment, the quiz items included in the quiz test presented can be at least one or more, and digital items of different numbers and / or grades can be provided according to the quiz results.

[0255] FIG. 6 is a flowchart for explaining a method of providing a digital item by the lottery method according to an embodiment of the present invention.

[0256] First, referring to FIG. 6 to explain the method of providing a digital item by the lottery method, in the embodiment, the application 111 can sense a user input for selecting the digital item to be acquired. (S301)

[0257] Specifically, in the embodiment, the application 111 can sense a user input for selecting the digital item to be acquired among all the different digital items by artist or / and by grade.

[0258] For this purpose, at least one or more digital items can be classified by a predetermined category and stored in advance in the digital item database 260.

[0259] For example, the predetermined category can include at least one of a first category classified by individual artist, a second category classified by artist group, and a third category classified by grade.

[0260] Also, in an embodiment, the user can select at least one or more of the attributes of the digital item and perform a user input to obtain a single digital item including the selected attribute.

[0261] At this time, the selected attribute can be an attribute of the category of the digital item database 260.

[0262] For example, the user can perform a user input to obtain a single digital item in which "S grade" and "A artist" are matched.

[0263] Also, in an embodiment, the user can select only the attributes for the first and second categories among the attributes of the digital item, and perform a user input to obtain a package type digital item in which the attributes of the third category are in any combination.

[0264] At this time, the package can be a product in which individuals and / or groups of artists corresponding to the first and second categories are specified, but the grades corresponding to the third category can be a product including a plurality of digital items set in a predetermined range.

[0265] For example, the user can perform a user input to obtain a digital item package in which "A artist" and / or "A group" are matched.

[0266] At this time, the package can include a general package including a plurality of digital items in which "C grade to S grade" are matched and a royal package including a plurality of digital items in which "A grade to S grade" are matched among the digital items in which "A artist" and / or "A group" are matched.

[0267] Also, in the embodiment, the user can purchase the right to use to determine whether the selected digital item can be obtained. At this time, the amount of the right to use may vary depending on the grade of the selected digital item.

[0268] For this purpose, in the embodiment, the application 111 can perform a settlement process for purchasing the right to use. Thereby, the user can purchase the right to use to obtain a digital item via a lottery method by paying a predetermined amount.

[0269] Also, when a digital item of a predetermined grade (for example, a grade of S or higher) is selected, in the embodiment, the application 111 can set predetermined conditions for purchasing the right to use to obtain the selected digital item.

[0270] For example, when the user selects a single digital item with which "S grade" is matched, in the embodiment, the application 111 can set conditions such that the right to purchase the right to use to obtain the selected S-grade digital item is possible only when "taking 100 or more simulation tests and possessing 10 or more digital items of grade A or higher".

[0271] Next, in the embodiment, the application 111 can extract the artist and grade attributes that match the selected digital item attributes. (S303)

[0272] For example, when the user requests a lottery with the attributes of an S-grade A artist digital item in the S301 step, in the embodiment, the application 111 can set it so that one digital item among the digital items having the attributes of "A artist" and "S grade" can be selected.

[0273] In the embodiment, the application 111 can detect reference quiz data for Artist A among at least one or more reference quiz data stored in the problem bank database 240.

[0274] At this time, referring to FIG. 5 again, the detected reference quiz data for Artist A can be detected in descending order from data with high difficulty to data with low difficulty (for example, from the 10th difficulty class to the 1st difficulty class).

[0275] Next, in the embodiment, the application 111 can determine the difficulty level of the reference quiz data based on the grade of the acquired digital item. (S305)

[0276] Specifically, in the embodiment, the application 111 can determine the difficulty level of the reference quiz data to be presented in the quiz test based on the grade of the digital item acquired from the lottery.

[0277] At this time, in the embodiment, in order for the application 111 to determine the difficulty level of the reference quiz data based on the grade of the acquired digital item, among at least one or more reference quiz data, the range of reference quiz data that can be presented for each grade (hereinafter referred to as the presentation range) can be set.

[0278] For this purpose, at least one or more reference quiz data can be classified by a predetermined category and stored in advance in the problem bank database 240.

[0279] For example, the predetermined category can include a first category classified by individual artist, a second category classified by artist group, a third category classified by difficulty level, and the like.

[0280] In an embodiment, the application 111 can set a question range based on a predetermined criterion matched for each grade.

[0281] For this purpose, in an embodiment, the application 111 can match a predetermined difficulty class for each grade.

[0282] In an embodiment, the application 111 can determine the difficulty of quiz data based on the grade data of digital items obtained through a lottery.

[0283] Specifically, the application 111 can preset a lottery probability for each digital item grade data, and determine the difficulty of the quiz test submitted when selecting or / and the number of quiz tests so as to match the preset lottery probability. In one embodiment, the application 111 can detect a quiz test having a difficulty class with a correct answer probability corresponding to the lottery probability of the grade data of the selected digital item, and provide the detected quiz test to the user.

[0284] For example, when a lottery for SS grade digital item grade data is requested, a quiz test of the 10th difficulty class having a correct answer probability matching the SS grade lottery probability can be detected and presented.

[0285] Thereby, in an embodiment, the application 111 can detect the reference quiz data of the 10th difficulty class from the A artist-related reference quiz data stored in the question bank database 240 for the said question range and provide it as a lottery quiz test.

[0286] That is, the application 111 matches a predetermined upper percentage (%) value of the probability of acquisition for each grade data of digital items that can be acquired, extracts quiz data of a difficulty class having a correct answer probability that matches the percentage value, and among the extracted quiz data, a randomly selected quiz test can be presented to the user.

[0287] For example, in the embodiment, the application 111 can match values from 0% to 0.1% in the upper rank for the SS grade, and can match values from 80% to 100% in the upper rank for the C grade.

[0288] Thus, referring to FIG. 5 again, when the user selects an A artist-related digital item of the SS grade, in the embodiment, the application 111 can determine, as the question range, the upper 0% to 0.1% of the A artist-related reference quiz data sorted in ascending order of difficulty in the question bank database 240.

[0289] That is, if there are a total of 1000 A artist-related reference quiz data, among them, the upper 0.1% of the reference quiz data corresponds to the data with serial number 1, so this data can be set as the question range.

[0290] When the user selects an A artist-related digital item of the C grade under the same conditions, in the embodiment, the application 111 can set, as the question range, the data from serial number 800 to serial number 1000, which is the upper 80% to 100% of the reference quiz data.

[0291] Also, when the user selects a general and / or royal package including a plurality of digital items, the question range can be wider than when a single digital item is selected.

[0292] As described above, in the embodiment, the application 111 can determine the difficulty level of reference quiz data to be presented in a quiz test based on a predetermined criterion (e.g., a predetermined difficulty class and / or a top percentage (%) value) that matches the extracted grade.

[0293] In other embodiments, the application 111 can also extract a plurality of quiz tests from the question bank database 240 such that the total correct answer probability of the plurality of quiz tests matches the probability of obtaining digital item grade data that can be obtained. For example, the first quiz test and the second quiz test can be extracted and presented to the user such that the total correct answer probability obtained by multiplying the correct answer probability of the first quiz test and the correct answer probability of the second quiz test matches the probability of obtaining.

[0294] Next, in the embodiment, the application 111 can randomly determine a quiz test to be presented from among the reference quiz data including the extracted artist and the determined difficulty level. (S307)

[0295] Specifically, in the embodiment, the application 111 can randomly determine at least one or more pieces of reference quiz data from among a plurality of pieces of reference quiz data including the extracted artist and the determined difficulty level.

[0296] At this time, at least one or more pieces of reference quiz data randomly determined by the application 111 in the embodiment can be singular and / or plural, but for convenience of explanation, it can be referred to as the first piece of reference quiz data.

[0297] Next, in the embodiment, the application 111 can present the randomly determined first piece of reference quiz data as a quiz test. (S309)

[0298] For this purpose, in an embodiment, if a quiz test is executed by a user's input, the application 111 can expose a plurality of data included in the first reference quiz data determined randomly in a quiz format as shown in FIG. 7 on the display of the user terminal 100.

[0299] FIG. 7 is an example of a quiz test according to an embodiment of the present invention.

[0300] As shown in FIG. 7, the quiz test can include at least one or more artist information data 251, question data 510, and answer data 520.

[0301] The artist information data 251 included in the quiz test and provided to the user can be data including at least one or more of a photo, an image, a voice, and a sound source of an artist according to the question type included in the first reference quiz data.

[0302] Further, when the first reference quiz data determined randomly and presented is not a question regarding a photo, an image, a voice, and a sound source of an artist but a question simply asking for artist-related information in text, the artist information data 251 can also be omitted.

[0303] Also, the question data 510 can be included one by one per each reference quiz data regardless of the question type of the first reference quiz data.

[0304] Also, when the answer type included in the first reference quiz data is objective, the answer data 520 can include a plurality of examples, and when it is subjective, it can include a text box for inputting a predetermined text.

[0305] In an embodiment, the user can select at least one or more of the plurality of examples or input a predetermined text.

[0306] When there are multiple reference quiz data items that are presented as a quiz test, such problem data 510 and answer data 520 can change each time the next reference quiz data item is presented.

[0307] Also, the user may be required to register and submit an answer within a predetermined time (e.g., 3 to 5 seconds) for the first reference quiz data item presented.

[0308] At this time, when presenting the first reference quiz data item corresponding to the quiz test, in order to eliminate the possibility of searching and receiving help from others, in an embodiment, the application 111 can set conditions such as blocking so that the execution state of the application 111 cannot be switched to background execution, or requesting an answer within a predetermined time.

[0309] In such a manner, the user can submit response data for the quiz test by making a predetermined user input for the first reference quiz presented.

[0310] Also, in an embodiment, the application 111 can determine whether the submitted response data is correct. (S311)

[0311] Then, based on whether the submitted response data is correct (or the score), the application 111 can determine at least one of the attributes of the acquisition availability, the number of acquired items, and the grade data of the digital items to be provided to the user, and randomly select a digital item corresponding to the determined attribute and provide it to the user.

[0312] At this time, in an embodiment, when there are multiple reference quiz data items presented as the quiz test and thus multiple submitted response data items, the application 111 can also determine whether the answers are correct and calculate the total score by summing up the preset scores for each reference quiz data item.

[0313] Next, in the embodiment, when the user guesses the correct answer, the application 111 can provide the digital item selected in step S301 (S313-1). On the other hand, when the user fails to guess the correct answer, the digital item may not be provided. (S313-2)

[0314] Also, in the embodiment, when the user guesses the correct answer for a predetermined number of the plurality of reference quiz data, the application 111 can also provide digital items of a differential grade among the digital items of the artist selected in step S301 according to the calculated total score.

[0315] In order to provide digital items of a differential grade according to the calculated total score, in the embodiment, the application 111 can preset a predetermined total score standard.

[0316] For example, in the embodiment, when the calculated total score is 100 points, the application 111 can provide digital items of the selected grade.

[0317] Also, when the calculated total score is 80 points or more and less than 100 points, digital items one grade lower than the selected grade can be randomly provided.

[0318] Also, when the calculated total score is 60 points or more and less than 80 points, digital items two grades lower than the selected grade can be randomly provided.

[0319] When there are no digital items one grade lower and / or two grades lower (for example, when the grade of the digital item selected in step S301 is grade C), digital items of the lowest grade that can be provided can also be randomly provided.

[0320] The randomly provided digital items can have only the grade be random, and the matched artists can be the same.

[0321] Also, if the calculated total score is less than 60 points, it may be regarded that the user failed to answer correctly, the paid digital item is incinerated, and no new digital item is provided.

[0322] Also, in the embodiment, when the user answers correctly for a predetermined number of the plurality of reference quiz data, the application 111 can determine the number of provided digital items of a differential grade among the digital items of the artist selected in step S301 according to the calculated total score, and pay out the determined number of provided items.

[0323] Also, when the first reference quiz data of the highest difficulty level (for example, the top 0.1% etc.) is presented in step S309, and the user answers correctly and obtains the highest grade digital item through steps S311 and S313-1, in the embodiment, the application 111 can delete the first reference quiz data from the question bank database 240 or modify it so that the first reference quiz data is not presented any more.

[0324] Conversely, when the user fails to answer the first reference quiz data of the highest difficulty level, the first reference quiz data can be maintained as it is in the question bank database 240 without being deleted so that it can be presented again in the quiz test.

[0325] This can reduce the possibility of easily providing the highest grade digital item and maintain the quiz quality of the reference quiz data corresponding to the highest difficulty level.

[0326] After going through the steps described above, the application 111 according to the embodiment of the present invention can provide digital items of the attributes that the user attempts to obtain.

[0327] Also, in the embodiment, the application 111 can compare the payment rate for each digital item grade data of at least one or more reference quiz data passed through the quiz test with the acquisition rate for each grade data of the preset digital items, and adjust the difficulty level of the reference quiz data.

[0328] And, in the embodiment, the application 111 can adjust the quantity of the digital items paid according to the grade through the difficulty adjustment, and adjust the payment rate of the digital items.

[0329] For this reason, in the embodiment, the application 111 can grasp the number of digital items paid to the user according to the grade.

[0330] Also, in the embodiment, the application 111 can change the difficulty level matched to the grade based on the number grasped according to the preset criteria for each grade.

[0331] Specifically, in the embodiment, when the grasped number exceeds the preset criteria of the first grade, the application 111 can increase the difficulty level matched to the grade to make it difficult for the user to obtain digital items, thereby adjusting the supplied quantity.

[0332] For example, assuming that the preset criteria for the S grade is 100 pieces, if the number of digital items of the S grade paid to the user is 100 pieces or more, in the embodiment, the application 111 can increase the difficulty level class matched to the S grade in preparation for the risk of the rarity of the S grade decreasing.

[0333] Also, in the embodiment, when the grasped number exceeds the preset standard of the first grade, the application 111 can also adjust the supplied quantity by increasing the number of questions in at least one or more reference quiz data belonging to the grade to make it difficult for the user to obtain digital items.

[0334] For example, under the same exemplification, in the embodiment, when the user participates in a quiz test for obtaining an S-grade digital item, the application 111 can increase the number of S-grade questions presented from 3 to 5.

[0335] That is, in the embodiment, the application 111 can increase the difficulty level of the reference quiz data presented in the quiz test and lower the probability of the user obtaining digital items by changing the difficulty level class matched to the first grade based on the grasped number or increasing the number of questions in at least one or more reference quiz data belonging to the first grade, so as to adjust the quantity by grade.

[0336] Also, in the embodiment, the application 111 can adjust the difficulty level by changing the predetermined data included in at least one or more reference quiz data based on the digital item payment rate.

[0337] For this purpose, in the embodiment, when the digital item payment rate exceeds the acquisition rate standard of the preset digital item grade, the application 111 can deform and present the questions of the reference quiz data.

[0338] That is, in the reference quiz data, a content area for adjusting the difficulty level is set in the question part. When the difficulty level needs to be adjusted, the set content area of the reference quiz data can be changed to increase / decrease the difficulty level.

[0339] Specifically, in the embodiment, the application 111 can adjust the difficulty level of the first reference quiz data by changing the exposure range of the artist information data included in the first reference quiz data where the payment rate of the digital item exceeds a preset standard.

[0340] For example, the application 111 can increase the difficulty level of the first reference quiz data by reducing the exposure range of the image and picture of artist A included in the first reference quiz data, or reducing the playback time of the voice and sound source. Similarly, the difficulty level of the first reference quiz data can be decreased by increasing the exposure range of the image and picture, or increasing the playback time of the voice and sound source.

[0341] Also, in the embodiment, the application 111 can adjust the difficulty level of the first reference quiz data by changing the answer type included in the first reference quiz data where the payment rate of the digital item exceeds the acquisition rate according to the preset digital item grade.

[0342] For example, the application 111 can increase the difficulty level of the first reference quiz data by changing the answer type included in the first reference quiz data from objective to subjective, or increasing the number of options in the objective type. Similarly, the difficulty level of the first reference quiz data can be decreased by changing the answer type from subjective to objective, or reducing the number of objective items.

[0343] On the other hand, referring to FIG. 8 to explain the method of increasing the grade matched to the digital item held in the synthesis method, in the embodiment, the application 111 can sense a user input for selecting at least two or more digital items to be synthesized. (S501)

[0344] Specifically, in an embodiment, the application 111 can sense a user input for selecting at least two or more digital items that the user intends to synthesize among the digital items owned by the user.

[0345] Here, the synthesis method can be a method that provides a function of obtaining digital items with an upgraded rank to a number less than the number of digital items paid after requesting synthesis by paying at least two or more of the digital items owned by the user and passing a quiz test. At this time, the user who makes a user input for selecting digital items to be synthesized in the embodiment can be a user who has purchased the right to perform synthesis between digital items.

[0346] Also, when selecting at least two or more digital items to be synthesized in the embodiment, predetermined conditions can be applied.

[0347] Specifically, in an embodiment, the application 111 can apply a condition to match at least one attribute among a plurality of digital items to be synthesized.

[0348] For example, in an embodiment, the application 111 can be such that a plurality of digital items input during synthesis are the same artist or / and artist group.

[0349] Also, in an embodiment, the application 111 can be such that a plurality of digital items input during synthesis are of the same rank.

[0350] For this purpose, in an embodiment, when a first digital item is first input, the application 111 can detect a second digital item having an attribute that matches the attribute of the first digital item among a plurality of digital items owned by the user, and activate and display the detected second digital item.

[0351] For example, conditions such as the grades of at least two or more digital items must be the same, and the number of digital items to be synthesized is limited to a maximum of n items can be set. At this time, for example, even if 10 digital items with the same grade are selected as synthesis targets, depending on the synthesis result, the provided digital item can be 1 item.

[0352] In the embodiment, the application 111 can perform a predetermined step described later in order to determine whether the synthesis of the selected digital item is successful.

[0353] Next, in the embodiment, the application 111 can determine predetermined attribute data that matches the selected digital item. (S503)

[0354] Specifically, in the embodiment, the application 111 is based on at least two or more selected digital items, and according to the synthesis result, so as to match the at least two or more digital items, it can determine predetermined attribute data of the obtained digital item (in the embodiment, artist personal name, artist group name, artist gender, artist affiliated company, and grade, etc.).

[0355] For example, when the user selects in step S503 a digital item (S grade) of artist B belonging to group A girls and a digital item (S grade) of artist C belonging to group A girls, in the embodiment, the application 111 can determine data such as "group A", "female", "artist B", "artist C", and "S grade".

[0356] For this reason, in the embodiment, the application 111 can detect predetermined reference quiz data from among at least one or more reference quiz data stored in the problem bank database 240 by the determined attribute item data.

[0357] Next, in the embodiment, the application 111 can determine the difficulty level based on the grade of the digital item obtained based on the grade data among the determined predetermined attribute data. (S505)

[0358] For this purpose, in the embodiment, the application 111 can determine the grade of the digital item obtained through synthesis based on the grade data among the determined predetermined attribute data.

[0359] Specifically, in the embodiment, the application 111 can determine the grade of the acquirable digital item among grades that are at least the same as the extracted grade data and / or higher than the extracted grade data.

[0360] Also, in another embodiment, the application 111 can determine the grade of the digital item obtained at the time of successful synthesis based on the user input of the user who selects the grade. At this time, the application 111 can be provided to select among grades that are the same as or higher than the extracted grade data.

[0361] Once the grade of the acquirable digital item is determined, in the embodiment, the application 111 can determine the difficulty level of the reference quiz data that is scheduled to be presented in the quiz test according to the determined grade.

[0362] At this time, in the embodiment, the application 111 can determine the difficulty level of the reference quiz data that is scheduled to be presented in the quiz test to be higher as the determined grade is higher.

[0363] Also, in the embodiment, the application 111 can set a predetermined question range for each grade in order to determine the difficulty level of the reference quiz data based on the determined grade.

[0364] The description of the method for setting the question range is the same as that of step S305 described above, so it can be applied mutatis mutandis. In the same way, in the embodiment, application 111 can determine the difficulty level of the reference quiz data to be used in the quiz test based on a predetermined criterion that matches the determined grade. Here, the predetermined criterion can mean the probability of obtaining a digital item by successful synthesis, and in other meanings, it can mean the probability for successful synthesis of the digital item to be obtained.

[0365] Next, in the embodiment, application 111 can determine the target artist of the digital item obtained based on the determined predetermined attribute data. (S507)

[0366] Specifically, in the embodiment, application 111 can determine the target artist of the digital item obtained at the time of successful synthesis based on the determined predetermined attribute data (in the embodiment, at least one of the data of the individual activity name of the artist, the name of the group to which the artist belongs, the gender of the artist, and the data of the company to which the artist belongs).

[0367] At this time, when the artist personal name data among the predetermined attribute data of each of the plurality of digital items matches, in the embodiment, application 111 can determine the target artist of the digital item that can be obtained as the artist.

[0368] For example, among the predetermined attribute data determined for each of a plurality of digital items, if the artist individual activity name data includes "Artist A", in an embodiment, the application 111 can determine the target artist of the acquirable digital item as "Artist A". Also, among the attribute data of a plurality of digital items, although the artist personal name data is different, if the artist group name data matches, in an embodiment, the application 111 can determine the target artist of the acquirable digital item as the said artist group.

[0369] For example, among the determined predetermined attribute data, if the artist personal name data is "Artist A" and "Artist B", but the artist group name data is "Group C", in an embodiment, the application 111 can determine the target artist group of the acquirable digital item as "Group C".

[0370] At this time, if the target of the acquirable digital item is not an artist individual but a group, the reference quiz data described later may be a quiz regarding the said group, and the digital item provided at the time of successful synthesis may also be a digital item for the said group.

[0371] Also, if none of the determined predetermined attribute data match, in an embodiment, the application 111 can determine the target artist of the acquirable digital item as at least one of the extracted first and second artist individual activity names and the first and second artist group names.

[0372] For example, if the input first digital item has the artist individual activity name data as "Artist A", the artist group name data as "Group C", and the input second digital item has the artist individual activity name data as "Artist B" and the artist group name data as "Group D", the application 111 can determine at least one of the target artists of the acquirable digital items as an individual of "Artist A", an individual of "Artist B", "Group C", and "Group D".

[0373] Next, in the embodiment, the application 111 can determine the attributes of the reference quiz data presented by the attribute data of the acquirable digital items through synthesis. (S509)

[0374] Specifically, in the embodiment, the application 111 can determine the attributes (in the embodiment, the difficulty level and the target artist) of the reference quiz data presented by the grade data of the acquirable digital items and the target artist.

[0375] Also, in the embodiment, the application 111 can detect the reference quiz data matched to the target artist of the acquirable digital items in the question bank database 240.

[0376] For example, in the embodiment, when the acquirable digital item is "Artist A" of "SS grade", the application 111 can determine the attributes including the difficulty level belonging to the correct answer rate ranging from 0% to 0.1% that is matched to the SS grade related to "Artist A", and can detect the corresponding reference quiz data in the question bank database 240.

[0377] The description of the process of determining the reference quiz data presented by the synthesis request is the same as the process of determining the reference quiz data in the lottery, so the overlapping description is omitted.

[0378] Then, the application 111 can randomly determine quiz data for a quiz presented with a plurality of detected reference quiz data.

[0379] Specifically, in the embodiment, the application 111 can determine, as a quiz test for the synthesis request, at least one or more randomly selected reference quiz data from among a plurality of reference quiz data having a difficulty level determined for an acquirable digital item and attributes corresponding to the target artist.

[0380] Next, in the embodiment, the application 111 can present the randomly determined first reference quiz data as a quiz test. (S511)

[0381] Since the detailed description thereof is the same as the content of step S309 described above, the content is incorporated by reference and omitted.

[0382] Also, in the embodiment, the application 111 can determine whether the submitted response data is correct. (S513)

[0383] At this time, in the embodiment, when there are a plurality of reference quiz data presented as a quiz test and thus a plurality of submitted response data, the application 111 can determine whether the answer is correct and calculate a total score obtained by summing up the scores preset for each reference quiz data.

[0384] Next, in the embodiment, when the user guesses the correct answer, the application 111 can provide one digital item among the digital items having the grade determined in step S505 and the attributes of the target artist determined in step S507. (S515-1)

[0385] In other words, in the embodiment, if the user answers correctly the reference quiz data for which the application 111 has set a quiz test, the application 111 can provide one digital item whose grade is higher than the grades of at least two or more digital items selected as synthetic materials in step S501.

[0386] In the embodiment, the price information included in the NFT smart contract data of the digital item provided by the successful synthesis can be higher than that of the digital item before the synthesis.

[0387] Also, in the embodiment, the application 111 additionally strengthens and upgrades the digital item provided by the successful synthesis, and adds predetermined content to the NFT media data included in the digital item, or improves the quality of the existing content to increase the rarity value, thereby increasing the price information included in the NFT smart contract data.

[0388] On the other hand, in the embodiment, if the user answers correctly a predetermined number of the multiple reference quiz data, the application 111 can provide digital items of different grades according to the calculated total score.

[0389] In order to provide digital items of different grades according to the calculated total score, in the embodiment, the application 111 can preset a predetermined total score standard.

[0390] For example, in the embodiment, if the calculated total score is 100 points, the application 111 can provide a digital item whose grade is higher than the grades of at least two or more digital items selected as synthetic materials.

[0391] Also, if the calculated total score is 80 points or more and less than 100 points, the application 111 can randomly provide a digital item whose grade is the same as that of at least two or more digital items selected as synthetic materials.

[0392] In addition, when the calculated total score is 60 or more but less than 80, digital items one grade lower than at least two or more of the digital items selected as the composite material can be randomly provided.

[0393] When there are no such digital items one grade lower (for example, when the grades of at least two or more of the digital items selected as the composite material are grade C), the lowest grade digital items that can be paid can also be randomly provided.

[0394] For the randomly provided digital items, only the grade is random, and the matched artist can be the same.

[0395] In addition, when the calculated total score is less than 60, it is regarded that the user could not guess the correct answer, at least two or more of the paid digital items are incinerated, and high-grade digital items due to successful synthesis may not be provided.

[0396] Conversely, when the user cannot guess the correct answer, the application 111 can incinerate at least two or more of the digital items selected for synthesis in step S501. (S515-2)

[0397] In such a case, in the embodiment, the application 111 has the effect of maintaining the rarity of the digital items including the predetermined grade through incineration when the quantity of the predetermined grade is excessively provided to the users.

[0398] FIG. 9 is an example of a digital item provided according to an embodiment of the present invention.

[0399] As shown in FIG. 9, the digital item DI can include at least one or more of the artist image 710, text 720, and auditory 730.

[0400] In an embodiment, the digital item DI can include the artist image 710 as the main content, and can further include at least one of the text 720 and the auditory 730 as the sub-content. Specifically, in an embodiment, the first digital item can include at least one or more sub-contents in one main content.

[0401] In an embodiment, the artist image 710 included in the digital item DI is an image of an artist individual and / or group representing the appearance of the artist, and can be, for example, one of a photo or image of the artist, a drawing (e.g., a caricature, etc.).

[0402] Also, in an embodiment, the text 720 can be numbers and characters that are displayed overlapping the artist image 710. For example, it can include the artist's album name, the name of the artist individual and / or group, a memorial day, etc. It can also include a text image written by the artist.

[0403] Also, in an embodiment, the text 720 can be composed of a font specified by the user and / or administrator, or a font including the actual handwriting of the artist.

[0404] Also, in an embodiment, the auditory 730 can mean the content output as audio when the user inputs when selecting the availability of output of the auditory on the artist image 710. For example, it can include a part of the artist's sound source and a voice message consisting of the artist's voice.

[0405] <Digital Item>

[0406] On the other hand, the application 111 according to the embodiment can provide a user interface UI (User Interface) for selecting the main content and sub-content that make up the digital item DI in order to generate the digital item DI. FIG. 10 is an example of a UI for selecting the main content of a digital item according to an embodiment of the present invention. That is, the application 111 according to the embodiment can upgrade the rank of the digital item DI through quiz answering and enhancement or synthesis, and can provide a user interface for generating an upgraded digital item DI that can be deformed to suit the user's taste.

[0407] As shown in FIG. 10, in the embodiment, the application 111 can sense the selection of the artist image 710 used as the main content of the digital item DI based on the UI.

[0408] Specifically, in the embodiment, the application 111 can provide at least one or more fixed images 710-1 to 710-3 and / or moving images 711-1 to 711-3.

[0409] Thereby, in the embodiment, the application 111 can sense the selection of the artist image 710 used as the main content of the digital item DI based on the user input.

[0410] Also, in the embodiment, when the user selects a fixed image based on the UI, the application 111 can change the attributes of a predetermined area that makes up the fixed image.

[0411] The predetermined area may include a first area 712 including the artist's hair, second areas 713-1 and 713-2 including the artist's clothing, and a third area 714 including the background of the artist image.

[0412] The second areas 713-1 and 713-2 can exist in multiple forms depending on the clothing (e.g., jackets, underwear, one-piece dresses, shoes, etc.) and accessories (e.g., hats and bags, etc.) worn by the artist, and the number is not limited to what is shown in the illustration.

[0413] As one embodiment, the application 111 can change the attributes of the artist image 710 by changing the hue and style of the first area 712 and the second areas 713-1 and 713-2 based on user input.

[0414] Also, the attributes of the artist image 710 can be changed by changing the hue and pattern of the third area 714.

[0415] Also, in an embodiment, after selecting the artist image 710 used as the main content of the digital item DI as described above, the application 111 can provide a user interface for selecting sub-content to be added to the selected artist image 710.

[0416] FIG. 11 is an example of a UI for selecting sub-content of a digital item according to an embodiment of the present invention.

[0417] As shown in FIG. 11, in an embodiment, the application 111 can sense the selection of at least one or more texts 720 and auditories 730 used as sub-content of the digital item DI based on the UI.

[0418] Specifically, in an embodiment, the application 111 can provide at least one or more texts 720-1 to 720-3 and / or auditories 730-1 to 730-3.

[0419] Thereby, in an embodiment, the application 111 can sense the selection of at least one or more texts 720 and auditories 730 used as sub-content of the digital item DI based on user input.

[0420] Also, in an embodiment, the application 111 can change attributes by adding the number of texts 720 included in the sub-content or adding a predetermined effect to the texts 720.

[0421] Also, in an embodiment, the application 111 can change attributes by extending the playback time of the auditories 730 included in the sub-content.

[0422] That is, in an embodiment, the application 111 can provide a user interface for selecting the main content and sub-content of the digital item DI. Thereby, the user can select one image from at least one or more fixed images and / or moving images, and determine the main content by changing the attributes of a predetermined area constituting the selected image. The user can determine the sub-content by adding at least one or more texts 720 and auditories 730 output on the main content. Therefore, the artist image 710 based on the user input can be customized.

[0423] Next, the service server 200 according to the embodiment can generate a plurality of unique digital items DI formed by a combination of at least one or more texts 720 and auditories 730 output on the artist image 710 customized based on the application 111.

[0424] In other words, the plurality of digital items DI can be unique digital items DI in a large number of combinations where the artist image 710 included in the main content, the attributes of a predetermined area constituting the artist image 710, the text 720 included in the sub-content, and the number / type / attributes of the auditory 730 are all different.

[0425] Also, in the embodiment, the service server 200 can register each of such a plurality of digital items DI as an NFT.

[0426] Specifically, in the embodiment, the service server 200 can use blockchain technology for each of the plurality of digital items DI to add NFT metadata including explanatory information, generator information, and storage address information, as well as owner information, transaction history information, condition information, and price information, and register them as unique NFTs.

[0427] Then, in the embodiment, the service server 200 can provide the plurality of digital items DI registered as the NFTs to the user as digital items based on the NFT, and can improve the grade of the digital items based on the provided NFT through synthesis and enhancement performed in the application 111. At this time, as the grade of the digital items based on the NFT improves, the price information included in the NFT smart contract data also improves, and the asset value of the digital items can increase.

[0428] For this purpose, in the embodiment, the service server 200 can determine the grade of each NFT-based digital item based on the main content and sub-content included in the NFT-based digital item.

[0429] At this time, the elements for determining the grade may include the resolution and image playback length of the artist image 710 included in the main content of the NFT-based digital item, the number, attributes of the text 720 included in the sub-content, and the sound quality and audio playback length of the auditorily 730.

[0430] In other words, the elements for determining the grade may include a first element for the resolution of the main content, a second element for the image playback length of the main content, a third element for the number of texts 720 in the sub-content, a fourth element for the attributes of the text 720 in the sub-content, a fifth element for the sound quality of the auditorily 730 in the sub-content, and a sixth element for the audio playback length of the auditorily 730 in the sub-content.

[0431] In the embodiment, the service server 200 can provide an NFT digital item of a higher grade than the paid NFT digital item by raising the steps of the first to sixth elements included in the NFT digital item paid by the user for enhancement and synthesis due to successful enhancement and synthesis.

[0432] For this purpose, in the embodiment, the service server 200 can set each predetermined detailed step (for example, the first step to the tenth step) of the first to sixth elements.

[0433] At this time, the detailed step can be such that the first step has the lowest quality / quantity attribute, and the tenth step has the highest quality / quantity attribute. Also, the first step can be the step designated as the default.

[0434] Specifically, in an embodiment, the service server 200 can set a first step with the lowest resolution to a tenth step with the highest resolution in a first element with respect to the resolution of the main content.

[0435] Also, in an embodiment, the service server 200 sets, in a second element with respect to the image reproduction length of the main content, the case where the artist image 710 included in the main content is a fixed image that does not move as the first step, and can set a second step with the shortest image reproduction length to a tenth step with the longest image reproduction length.

[0436] Also, in an embodiment, the service server 200 can set a first step where the number of texts 720 of the sub-content is 0 to a tenth step where the number of texts 720 is 10 in a third element with respect to the number of texts 720 of the sub-content.

[0437] Also, in an embodiment, the service server 200 can set a first step where the number of attributes added to the text 720 is 0 to a tenth step where the number of attributes added to the text 720 is 10 in a fourth element with respect to the attributes of the text 720 of the sub-content. At this time, the attributes added to the text 720 may include font upgrade, character size upgrade, addition of effects (such as shine and movement), and the like.

[0438] Also, in an embodiment, the service server 200 can set a first step with the lowest sound quality of the audio 730 of the sub-content to a tenth step with the highest sound quality in a fifth element with respect to the sound quality of the audio 730 of the sub-content.

[0439] Also, in an embodiment, the service server 200 can set a first step with the shortest audio reproduction length of the audio 730 of the sub-content to a tenth step with the longest audio reproduction length in a sixth element with respect to the audio reproduction length of the audio 730 of the sub-content.

[0440] That is, in the embodiment, the service server 200 can determine a higher grade for the NFT digital item as it is closer to the 10th step where the resolution of the main content included in the NFT-based digital item is the highest, the image playback length is the longest, the number of texts of the sub-content is the largest, the number of attributes added to the text is the largest, the audio quality of the sub-content's audio is the highest, and the audio playback length is the longest.

[0441] Also, in the embodiment, when the enhancement is successful, the service server 200 can raise the steps of at least one or more of the first to sixth elements included in the NFT digital item paid by the user for enhancement to a predetermined step (for example, 1 step and / or 1 step or more).

[0442] Also, in the embodiment, when the synthesis is successful, the service server 200 can raise the steps of at least one or more of the first to sixth elements included in at least two or more NFT digital items paid by the user for synthesis to a predetermined step (for example, 1 step and / or 1 step or more). At this time, the steps of each of the first to sixth elements included in at least two or more NFT digital items paid for synthesis are the same, and thus the grades can also be the same.

[0443] At this time, in the embodiment, the service server 200 can randomly determine at least one or more of the first to sixth elements whose steps are raised by the enhancement and synthesis success, or determine them as the user's selection input based on the application 111.

[0444] In such a manner, in other words, in an embodiment, the service server 200 senses an input for paying at least one or more NFT digital items owned by a user for enhancement and / or synthesis, executes a quiz test with a differential level of difficulty based on the level of the at least one or more paid NFT digital items, and if the result of the executed quiz test meets a predetermined condition, can provide a high-level NFT digital item for the at least one or more paid NFT digital items.

[0445] For example, in an embodiment, if the service server 200 senses that a user pays n digital items with a resolution at the first step as synthesis materials and successfully synthesizes them by passing a quiz test, the service server 200 can provide a first digital item with a resolution at the second step, thereby providing a digital item of a higher level than the paid digital items.

[0446] That is, in an embodiment, the service server 200 can enhance the detailed steps for each element determining the level, and through synthesis and enhancement between digital items, provide a digital item of a higher level than the level matched to the digital item paid for the synthesis and enhancement.

[0447] For example, in an embodiment, the service server 200 can provide a digital item with an increased resolution of the main content included in the digital item paid for by successful enhancement and synthesis, or a digital item with an increased image playback length.

[0448] Also, in an embodiment, the service server 200 can provide a digital item with an increased number and attributes of texts 720 among the sub-contents included in the digital item paid for by successful enhancement and synthesis.

[0449] Also, in the embodiment, the service server 200 can provide a digital item in which the audio playback length of the auditorium 730 among the sub - contents included in the digital item paid for by enhancement and synthesis is increased.

[0450] On the other hand, in the embodiment, the service server 200 can provide a function of upgrading a digital item by transforming the artist image 710, which is the main content of the digital item, through a generative artificial intelligence model so as to match the user's taste.

[0451] For this purpose, the service server 200 can include a generative artificial intelligence model that generates the artist image 710 of the digital item based on the user's text and sketches.

[0452] Such a generative artificial intelligence model can be a model in which, in addition to a generative artificial intelligence model such as existing Stable Diffusion, the artist's image is additionally learned, and a plurality of styles of digital items are each additionally learned.

[0453] That is, the generative artificial intelligence model can precisely generate an artist image based on the artist of the digital item by additionally learning a plurality of images of the artist for each artist.

[0454] Also, the generative artificial intelligence model can be additionally learned according to the style of the artist image for each digital item of the artist.

[0455] For example, the generative artificial intelligence model can be learned by designating the first digital item issued at the time of the release of Album B for Artist A as Style K, and the second digital item issued by the B performance of Artist A as Style L.

[0456] That is, the generative artificial intelligence model can generate an artist image upgraded to match the style of the digital item and the artist of the digital item to be enhanced / synthesized.

[0457] More specifically, if the user attempts to newly generate an artist image 710 of a digital item through enhancement / synthesis, first, the artist image 710 modification function can be selected via the application 111.

[0458] Then, when the user modifies the artist image via the application 111, the desired direction can be led to artist image transformation by attaching text, a sketch image, or / and a photo, etc.

[0459] For example, the user can input their own photo into the application 111 and input a request such as "Generate an image where the person in the photo and the artist perform action A (e.g., shaking hands)".

[0460] The service server 200 that receives such an input can input the photo and text into the generative artificial intelligence model and generate an image that matches the user's request.

[0461] At this time, the service server 200 can maintain the artist attribute of the digital item by providing additional input to limit generation to the artist of the basic digital item used for artist synthesis / enhancement in the generative artificial intelligence model.

[0462] Also, the service server 200 can maintain the style of the digital item by providing additional input to generate the artist image in the style of the basic digital item used for artist synthesis / enhancement.

[0463] Through such a generative artificial intelligence model, users can generate their own digital content, which is the main need for NFT digital items, in the direction they desire. At this time, by maintaining the artist attributes and style attributes of the digital items, it is possible to prevent the digital item issuance direction of artists and planning companies from being randomly changed by users.

[0464] As described above, the method and system for providing NFT-based digital items according to the embodiments of the present invention have the effect of preventing illegal copying and the circulation of counterfeit goods pretending to be IP by digitalizing content products based on artist IP.

[0465] In addition, the method and system for providing NFT-based digital items according to the embodiments of the present invention have the effect of eliminating the possibility of probability manipulation by asking quizzes related to artists and distributing digital items according to the quiz results.

[0466] In addition, the method and system for providing NFT-based digital items according to the embodiments of the present invention have the effect of reducing the gambling nature by asking quizzes with different levels of difficulty according to the grades of digital items and adjusting the lottery / diversification / synthesis success probabilities.

[0467] In addition, the method and system for providing NFT-based digital items according to the embodiments of the present invention have the effect of maintaining the rarity of the digital items by applying reasonable difficulty levels to the grades of the digital items based on the success rate of obtaining digital items through quiz questions.

[0468] In addition, the method and system for providing NFT-based digital items according to the embodiments of the present invention have the effect of improving fan satisfaction and leading to high fan participation by distributing digital items that reflect the fans' preferences.

[0469] The embodiments of the present invention described above can be realized in the form of program instruction words that can be executed via various computer components and can be recorded on a computer-readable recording medium. The computer-readable recording medium can include program instruction words, data files, data structures, etc. alone or in combination. The program instruction words recorded on the computer-readable recording medium can be those specifically designed and configured for the present invention or those known and usable by those skilled in the computer software field. Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tapes, optical recording media such as CD-ROMs and DVDs, magneto-optical media such as floptical disks, and hardware devices specifically configured to store and execute program instruction words such as ROMs, RAMs, flash memories, etc. Examples of program instruction words include not only machine language codes such as those made by compilers but also high-level language codes that can be executed by a computer using an interpreter, etc. The hardware device can be changed into one or more software modules for performing the processing according to the present invention, and vice versa.
