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 winning probability of a lottery.

Background Art

[0002] Fandom refers to people or groups who passionately like, immerse themselves in, and get carried away with a specific person (especially an entertainer, 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 a probability-based item provided in an online game service. They are classified into high-grade, medium-grade, and low-grade according to quality and rarity, etc., and can be provided to fans by means such as a lottery (gacha). 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 imposed on providing gacha services without disclosing the gacha probability, such as the introduction of the "Probability-Type Item Regulation Act", etc., to clearly state the composition ratio and types of acquirable items, the probability of an item appearing, etc.

[0005] However, since the stated probability is provided unilaterally by the site providing the service, there is still a possibility of probability manipulation by the provider.

[0006] Furthermore, since the items obtained through item synthesis are random items that do not reflect the user's choices, there was a problem where fans who support a particular artist would be very dissatisfied if the artist they support did not appear in the item.

[0007] On the other hand, in recent years, with the groundbreaking development of blockchain technology, the use of NFTs (Non-Fungible Tokens) based on it has expanded to various fields.

[0008] Here, NFT refers to a virtual token that uses blockchain technology to prove ownership of a digital asset.

[0009] Specifically, the NFT can be a type of virtual certificate of authenticity used to represent its unique originality and ownership by embedding an address that points to a predetermined digital file such as an image, picture, and / or audio within the token.

[0010] In other words, the aforementioned NFT can mean a unique digital file format registered on the blockchain, and such NFTs have the advantage that their economic value can gradually increase over time, and interest in such NFTs is steadily growing. [Overview of the Initiative] [Problems that the invention aims to solve]

[0011] This invention was devised to solve the problems of the prior art described above, and its purpose is to provide a method and system for providing digital items based on NFTs.

[0013] Furthermore, the present invention aims to provide a digital item provision method and system based on NFTs that presents quizzes about artists and provides digital items according to the quiz results.

[0014] Furthermore, the present invention aims to provide a digital item provision method and system based on NFTs that presents quizzes of varying difficulty levels according to the grade of the digital item and adjusts the success rate of lottery / enhancement / synthesis.

[0015] Furthermore, the present invention aims to provide a method and system for providing digital items based on NFTs, which manage the difficulty level based on the success rate of acquiring digital items through quizzes.

[0022] Furthermore, the step of constructing the problem bank database includes the steps of conducting a mock test for multiple users based on multiple new quiz data, calculating the correct answer rate for each of the multiple quiz data based on the results of the mock test for the multiple users and determining the difficulty level based on the calculated correct answer rate, including the new quiz data whose difficulty level has been determined as reference quiz data in the problem bank database, and providing rewards to the multiple users who conducted the mock test.

[0023] Furthermore, the step of determining the grade data and target artist of the new digital item based on the input multiple digital items includes the steps of: extracting at least one data from the first artist's individual name, the first artist's group name, the first artist's gender, and the first grade that are matched to the first digital item of the input multiple digital items; extracting at least one data from the second artist's individual name, the second artist's group name, the second artist's gender, and the second grade that are matched to the second digital item of the input multiple digital items; and determining the target artist or artist group that matches the data extracted from the first digital item and the second digital item.

[0024] Also, the step of determining the difficulty level of reference quiz data to be presented in a quiz test based on the determined grade data includes: setting the synthesis success rate of new digital items of a predetermined level of grade data through the synthesis; determining the correct answer rate corresponding to the set synthesis success rate as the difficulty level; and setting at least one or more reference quiz data included in the determined difficulty level as the question range.

[0025] Also, the step of determining the target artist of the reference quiz data to be presented in the quiz test based on the determined target artist includes: if the first and second artist personal names are the same, determining the artist individual as the target artist; if the first and second artist personal names are different but the first and second artist group names are the same, determining the artist group as the target artist; and if the first and second artist personal names and the first and second artist group names are different but the first and second artist genders are the same, determining one of the first artist individual and the second artist individual as the target artist.

[0026] Also, the step of presenting the first reference quiz data corresponding to the determined difficulty level and target artist as a quiz test includes randomly determining the first reference quiz data included in the question range from all the reference quiz data for the determined target artist stored in the question bank database.

[0027] Also, the method for providing digital items based on NFT according to an embodiment of the present invention further includes: if the first reference quiz data is the highest difficulty level included within a predetermined question range, presenting it in a quiz test, and after the user answers correctly and a digital item is given to the user, deleting it from the question bank database.

[0035] The present invention can be modified in various ways and has various embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present invention, and the methods for achieving them, will become clear when referred to the embodiments described in detail below, along with the drawings. However, the present invention is not limited to the embodiments disclosed below and can be realized in various forms. In the following embodiments, terms such as "first," "second," etc., are used not in a restrictive sense but to distinguish one component from another. Also, singular expressions include plural expressions unless the context clearly indicates otherwise. Furthermore, terms such as "includes" or "has" mean that the features or components described in the specification exist, and do not preclude the possibility of adding one or more other features or components. Also, in the drawings, for illustrative purposes, the size of components, etc., may be exaggerated or reduced. For example, the size and thickness of each component shown in the drawings are arbitrarily shown for illustrative purposes, and the present invention is not necessarily limited to what is illustrated.

[0036] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components will be denoted by the same reference numerals, and redundant descriptions thereof will be omitted.

[0037] Figure 1 is a conceptual diagram of a digital item provision system based on NFTs according to an embodiment of the present invention.

[0038] As shown in Figure 1, the NFT-based digital item provision system according to an embodiment of the present invention (hereinafter referred to as the "digital item provision system") can provide a service (hereinafter referred to as the "digital item provision service") in which, when drawing lots, enhancing, and synthesizing digital items to which NFTs are applied, a predetermined quiz whose difficulty level is adjusted based on the rarity / grade of the digital item is presented, and the digital item is provided only to users who answer the quiz correctly.

[0039] The digital item provision system according to an embodiment of the present invention can provide digital items that are artist-specific goods that have been digitized, by issuing digital items to which a unique value is assigned via blockchain for each artist's goods.

[0040] The aforementioned "Digital Item" refers to a product that includes predetermined content, such as text, sound, images, and photographs, produced digitally. In this embodiment, it may mean digital content related to an artist (for example, a digital photo card).

[0041] In this embodiment, NFTs may be applied to the digital item, thereby allowing it to be traded in cryptocurrency and purchased / traded / exchanged on cryptocurrency exchanges for individual fans to collect and own.

[0042] In this case, the digital items can be enhanced and combined with other digital items in order to improve their quality, such as by collecting rare digital items or by adding predetermined content to existing digital items.

[0043] Furthermore, in the embodiment, the digital item may be initially provided to the user via at least one of the following methods: designation and random drawing.

[0044] In some embodiments, such digital items may include NFT media data, NFT metadata, and NFT smart contract data.

[0045] NFT media data refers to the original data, including the content itself, such as text, sounds, images, and pictures associated with the artist.

[0046] Furthermore, NFT metadata is data related to the original data and includes descriptive information, generator information, and storage address information.

[0047] Furthermore, NFT smart contract data is data related to digital items as assets, and includes information such as owner information, transaction history information, terms and conditions information, and price information.

[0048] In one embodiment, the asset value of such a digital item can be determined by the price information contained in the NFT smart contract data, which fluctuates depending on the rarity of the content of the NFT media data contained in the digital item.

[0049] For this purpose, in this embodiment, each digital item may be assigned a grade based on its rarity.

[0050] The rank of the aforementioned digital item can be assigned using numbers, letters, and star ratings, and the administrator can determine the rank based on its rarity and pre-match each digital item to the aforementioned rank. In this case, the rarer the digital item, the higher its rank can be.

[0051] For example, digital photo cards of multiple artists A can be pre-matched to different grades such as C, B, A, S, and SS, based on their rarity.

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

[0053] In other words, the embodiment can support the synthesis of digital items and provide a digital item selected as a synthesis material that is more rare.

[0054] Furthermore, in this embodiment, the digital item's grade can be improved by the quantity and quality of the NFT media data content contained within the digital item, thereby increasing the asset value of the digital item.

[0055] To this end, in the embodiment, predetermined content can be added to NFT media data contained in a digital item through enhancement and upgrade, or the quality of existing content can be improved.

[0056] For example, by enhancing and upgrading an artist's digital photocard, it may be possible to add content such as effects, album name text, artist audio files, and autographed images to the NFT media data, or to increase the resolution of the photos and images included in the NFT media data, or to increase the playback length of the audio files.

[0057] In other words, the higher the grade of the digital item, the greater the amount of content included in the digital item, or the higher the quality of the content can be.

[0058] On the other hand, when drawing lots, enhancing, or synthesizing digital items according to the embodiments of the present invention, a predetermined quiz with adjusted difficulty levels based on the grades of pre-matched digital items may be presented.

[0059] Furthermore, digital items that users can acquire through lottery / enhancement / synthesis can be provided to the user if the user requests to acquire them. The user will be given a quiz, and if the user answers the quiz correctly, the digital items will be provided to the user.

[0060] For example, if the digital item a user can acquire is of a low rank, a quiz with a low difficulty level may be presented, increasing the user's probability of acquiring the digital item. Conversely, if the digital item a user can acquire is of a high rank, a quiz with a high difficulty level may be presented, decreasing the user's probability of acquiring the digital item.

[0061] In one embodiment, the digital item provision system that provides the digital item provision service described above may include a user terminal 100, a digital item provision service server 200, an NFT service server 300, and a network 10.

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

[0063] Here, the network 10 in this embodiment refers to a connected structure that enables information exchange between each node, such as a user terminal 100, a digital item provision service server 200, and / or an NFT service provision server 300.

[0124] In this embodiment, each of the above-mentioned components can be implemented as a separate device from the service server 200, or it can be implemented as part of the service server 200. Hereinafter, it will be explained that each component is implemented as part of the service server 200, but it is not limited to this.

[0125] Specifically, in this embodiment, the quiz generation module 210 can construct a question bank database 240 according to the embodiment of the present invention.

[0126] To this end, the quiz generation module 210 can generate at least one quiz data based on predetermined artist information data (in this embodiment, such as artist photos, images, audio, sound sources, and detailed information) contained in the artist information database 250.

[0127] In this embodiment, artist information data can mean various pieces of information about the artist who is the subject of the quiz, and may include, for example, content including photographs, images, audio, and sound recordings of the artist included in the quiz, as well as a profile including the artist's hometown, educational background, and debut date.

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

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

[0130] In this case, the accuracy rate and difficulty level can be determined after at least one user has solved the newly generated quiz data, and can be default values ​​(e.g., 0) for new quiz data before it has been solved by a user.

[0131] Furthermore, in this 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] In this embodiment, the extracted artist information data can become the source of quiz data generated by the quiz generation module 210.

[0133] In addition, in this embodiment, the quiz generation module 210 can generate at least one new quiz data based on user inputs in which the extracted artist information data includes the artist name and / or artist group name, the date the question was generated, the question type (e.g., image / audio / visual / text, etc.), and the answer type (e.g., objective / subjective, etc.).

[0134] The entity that generates new quiz data based on the user input may be the administrator and / or the user of the user terminal 100 on which the fan platform application is installed (hereinafter referred to as "user").

[0135] At this time, new quiz data generated based on user input through direct user participation can be stored in the question bank database 240 after undergoing acceptance procedures by an administrator or other relevant party.

[0136] For example, the quiz generation module 210 can generate new quiz data based on information data of artist A contained in the artist information database 250, exposing only a part of artist A's image (e.g., hair, hands, clothing, etc.) and asking the user to guess which artist it is.

[0137] Furthermore, for example, the quiz generation module 210 can generate new quiz data that asks the user to guess which artist it is by playing only a portion of the voice and sound source of artist A (for example, the first second of the sound source) based on the information data of artist A contained in the artist information database 250.

[0138] Furthermore, for example, the quiz generation module 210 can publish information about artist A based on the artist information database 250, and generate new quiz data that asks users to guess artist A's date of birth, record release date, debut date, and preferences.

[0139] In other words, in this embodiment, such a quiz generation module 210 can generate at least one new quiz data based on input from the administrator and the user and store it in the question bank database 240.

[0140] At least one new quiz data generated by the quiz generation module 210 and stored in the question bank database 240 can be used as questions in a mock test, which is a quiz used to determine the difficulty level.

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

[0142] For example, the difficulty level can be expressed using numbers from 0 to 100, with higher numbers indicating greater difficulty, and can also be expressed by dividing it into predetermined classes such as very easy / easy / normal / difficult / very difficult.

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

[0144] This allows at least one user to perform a simulated test based on the fan platform application stored on the user terminal 100 and solve at least one new quiz data.

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

[0146] In other words, in this embodiment, the difficulty management module 220 can determine the difficulty level of at least one new quiz data stored in the question bank database 240 based on the correct answer rate of users who have solved predetermined new quiz data based on a mock test.

[0147] In this embodiment, the difficulty management module 220 can construct a question bank database 240 by converting newly determined quiz data into reference quiz data and storing it.

[0148] At least one reference quiz data stored in such a question bank database 240 can be used as a question in a practice test, which is a quiz presented when a user attempts to acquire a digital item through a lottery or synthesis, or 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 mock test and the actual test may contain the same quiz content, differing only in whether they are from before or after the difficulty level has been determined. By adjusting the difficulty level, only the predetermined data included in the quiz content may be changed.

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

[0151] In an embodiment, the reference quiz data may further include 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, difficulty level, and digital item distribution rate.

[0152] In this embodiment, the digital item distribution rate can be a value that represents the ratio of the number of times a digital item is distributed due to the user's correct answer to the total number of times the question is asked.

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

[0154] To this end, in this embodiment, if the rate of digital item distribution exceeds a preset standard, the difficulty management module 220 can determine that the probability of the user correctly answering the question has increased due to the frequent presentation of the question, and can modify predetermined data included in the reference quiz data.

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

[0156] Furthermore, in this embodiment, the digital item management module 230 can either increase the number of contents included in the digital item or improve its quality depending on the enhancement results of the digital item.

[0157] In addition, in this embodiment, the digital item management module 230 can replace a digital item held by the user with another digital item depending on the result of the digital item synthesis.

[0158] In addition, in this embodiment, the digital item management module 230 can work in conjunction with an external server 300 to trade (e.g., buy / sell / exchange, etc.) predetermined digital items that have value as cryptocurrency.

[0159] In addition, in this embodiment, the question bank database 240 can store and manage at least one or more quiz data items.

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

[0161] In this embodiment, at least one reference quiz data set included in the problem bank database 240 can be sorted by difficulty level. This allows setting the top percentage of sorted difficulty levels and extracting only the reference quiz data that includes difficulty levels within that range, a detailed explanation of which will follow later.

[0162] Furthermore, in this embodiment, the artist information database 250 can store and manage at least one or more artist information data items.

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

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

[0165] In addition, in this embodiment, the digital item database 260 can also store and manage digital item content that serves as a source for producing digital items (for example, photographs and images for producing digital photo cards, handwritten text images, artist voice audio files, etc.).

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

[0167] In addition, in this 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, commands, and / or data for realizing the digital item provision service.

[0168] On the other hand, the service server 200, which includes the above-mentioned components, can realize the digital item provision service by exchanging data with an external device such as a user terminal 100, which is necessary for the digital item provision process to be driven by the external device.

[0169] More specifically, in this embodiment, the service server 200 can provide an environment in which the application 111 can run on external devices (in this embodiment, such as a mobile computing device 100-1 and / or a desktop computing device 100-2).

[0170] For this purpose, the service server 200 may include application programs, data, and / or instructions for the operation of application 111, and may be able to send and receive various data based thereon with the external device.

[0171] In addition, in this embodiment, the service server 200 can store and manage various application programs, commands, and / or data for realizing the digital item provision service.

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

[0173] Furthermore, the service server 200 may include at least one quiz generation module 210, a difficulty management module 220, a digital item management module 230, a question bank database 240, an artist information database 250, and a digital item database 260.

[0174] However, the functional operations that the service server 200 can perform in the embodiment of the present invention are not limited to those described above, and it can also perform other functional operations.

[0175] On the other hand, in this embodiment, the service server 200 described above can be implemented by at least one computing device comprising at least one processor for data processing, at least one communication processor for data exchange with external devices, and at least one memory for storing various application programs, data, and / or instruction words for providing digital item provision services.

[0176] Here, the memory can store one or more of the following: an operating system OS for providing digital item services, various application programs, data, and instruction words.

[0177] Furthermore, the memory may include a program area and a data area.

[0178] Here, the program area according to the embodiment can be linked to the operating system (OS) that boots the server and functional elements, and the data area can store data generated by the use of the server.

[0179] In this embodiment, such memory may be various storage devices such as ROM, RAM, EPROM, flash drives, hard drives, etc., or it may be web storage that performs the storage function of the memory module on the internet.

[0180] On the other hand, the processor can control the overall operation of each of the aforementioned units in order to realize the digital item provision service.

[0181] Furthermore, for the sake of explanation, the operation of each module described above may be a subdivision of the operation of the processor, and the overall operation of the quiz generation module 210, the difficulty management module 220, and the digital item management module 230 can also be performed by the processor.

[0182] Such a processor may be a system-on-a-chip SOC suitable for a server, including a central processing unit CPU and / or a graphics processing unit GPU, and can execute an operating system OS and / or application programs stored in a memory module, and can control each component installed in the server.

[0183] Furthermore, the processor can communicate internally with each component via a system bus, and may include one or more predetermined bus structures, including a local bus.

[0184] Furthermore, a processor can be implemented using at least one of the following: ASICs (application-specific integrated circuits), DSPs (digital signal processors), DSPDs (digital signal processing devices), PLDs (programmable logic devices), FPGAs (field programmable gate arrays), controllers, microcontrollers, microprocessors, or other electrical units for functional execution.

[0185] In the above description, it has been explained that the service server 200 according to the embodiment of the present invention performs the functions described above. However, in various embodiments, it is possible that at least a part of the functions performed by the service server 200 can be performed by an external device (for example, a user terminal 100, etc.), and at least a part of the functions performed by the external device can be further performed by the service server 200.

[0186] • External Server 300

[0187] On the other hand, an external server 300 according to an embodiment of the present invention can provide predetermined data usable on the digital item provision service to a user terminal 100 and / or a service server 200.

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

[0189] For example, such an external server 300 may include a cryptocurrency trading platform server, etc.

[0190] In this embodiment, the external server 300 described above may include at least one data transmission / reception unit, a processor unit, and a database.

[0191] First, the data transmission / reception unit according to this embodiment can transmit and receive various types of data via the network 10 to support the digital item provision service in conjunction with external devices (for example, user terminal 100 and / or service server 200, etc.).

[0192] In one embodiment, the data transmission / reception unit 310 can exchange fan activity data based on external services with the user terminal 100 and / or service server 200 via a network.

[0193] Furthermore, the database according to the embodiment can store and manage various types of data to support the digital item provision service.

[0194] In one embodiment, the database can store and manage at least one of the following: an operating system OS for realizing a predetermined external service, various application programs, data, and instruction words, and can store and manage predetermined data based on the said external service.

[0195] Such a database may be any type of storage device, such as ROM, RAM, EPROM, flash drive, or hard drive, or it may be a web storage service that performs the function of storing the database over the internet.

[0196] Furthermore, the processor unit according to the embodiment can control the overall operation of each of the aforementioned components in order to realize a digital item provision service.

[0197] Such processor units can be implemented using at least one of the following: ASICs (application-specific integrated circuits), DSPs (digital signal processors), DSPDs (digital signal processing devices), PLDs (programmable logic devices), FPGAs (field programmable gate arrays), controllers, microcontrollers, microprocessors, and other electrical units for functional execution.

[0198] • How to build a question bank database by conducting mock tests.

[0199] The following describes in detail, with reference to the attached Figures 4 to 5, how an application 111 executed by at least one processor of a user terminal 100 according to an embodiment of the present invention performs a simulated test based on a fan platform application to construct a problem bank database 240.

[0200] In an embodiment of the present invention, at least one processor of the user terminal 100 can execute or run at least one application 111 stored in at least one memory 110.

[0201] Hereinafter, the process by which at least one processor operates to execute the instructions of the application 111 and construct the problem bank database 240 described above will be abbreviated as "the application 111 performs the operation."

[0202] Figure 4 is a flowchart illustrating a method for constructing a problem bank database according to an embodiment of the present invention.

[0203] As shown in Figure 4, in this embodiment, application 111 can perform a simulated test. (S101)

[0204] Specifically, in this embodiment, application 111 senses user input to select individual artists and groups, thereby enabling the execution of simulated tests associated with the selected individual artists and groups.

[0205] In another embodiment, application 111 can extract user fandom information, automatically select individual artists and groups corresponding to the fandom, and perform a simulated test associated with the selected individual artists and groups.

[0206] In this embodiment, the simulated test can be executed based on at least one new quiz data set that has been pre-generated by the administrator and / or the user.

[0207] Furthermore, in the embodiment, the simulated test may be a procedure that multiple users of the fan platform application 111 must perform periodically in order to verify the appropriateness of the difficulty level of at least one quiz data stored in the question bank database 240 (specifically, in the embodiment, determining the difficulty level of new quiz data and adjusting the difficulty level of reference quiz data).

[0208] In this embodiment, application 111 can set conditions such as providing users who perform the simulated test with predetermined rewards (e.g., fan points, eligibility to apply for concert tickets, coupons, and discount vouchers), or granting eligibility to perform the actual test only to users who have performed the simulated test a predetermined number of times or more.

[0209] Furthermore, in this embodiment, application 111 can recruit at least one user to perform a simulated test related to a specific artist.

[0210] This is because, in order to determine the difficulty level of new quiz data stored in the problem bank database 240 and convert it into reference quiz data and / or store it only after it has been solved a predetermined number of times by multiple users, new quiz data for artists who have not been solved a predetermined number of times is presented.

[0211] In this embodiment, application 111 can offer additional rewards to users who have performed a mock test related to the recruited specific artist.

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

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

[0214] In this case, each of the new quiz data includes an artist name and / or an artist group name, and is stored in the question bank database 240 separately for individual artists and / or groups. In this embodiment, application 111 can randomly extract and present predetermined quiz data from among a plurality of new quiz data associated with the artist selected in step S101.

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

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

[0217] Specifically, in the embodiment, application 111 can complete a mock test and store the results, including the number of times each of the at least one new quiz data presented in the mock test was presented, and whether the answer was correct or incorrect.

[0218] In this case, the number of times a question is presented can be a predetermined value calculated in order for new quiz data to be converted into reference quiz data, and the correct and incorrect answers for each of the at least one new quiz data presented in the mock test can be provided to the user terminal 100 and made public to the user.

[0219] Steps S101 to S105 described above can be repeated by multiple users utilizing the fan platform according to the embodiment of the present invention, thereby allowing the number of times each new quiz data is presented, and whether the answer is correct or incorrect, to be accumulated based on the number of times it has been performed.

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

[0221] Specifically, in this embodiment, application 111 can calculate the correct answer rate for new quiz data that meets a predetermined number of question counts based on the stored results.

[0222] In this embodiment, the number of times the question is asked is a predetermined number of times that the question must be asked at least in order to calculate objective statistics, and can be set in advance by the administrator. For example, the number of times the question is asked in advance can be set to 100 times, etc.

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

[0224] Furthermore, the aforementioned correct answer rate can be expressed as a percentage (%) of the number of users who answered correctly relative to the total number of users who solved each new quiz. For example, if 200 users solved the quiz and 10 of them answered correctly, the correct answer rate could be 10 / 200 = 5%.

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

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

[0227] For this purpose, in embodiments of the present invention, it is possible to classify at least one difficulty class into which a predetermined range of correct answer rates is set in advance.

[0228] In this embodiment, application 111 can determine the difficulty level of new quiz data by deriving a difficulty class for the range of correct answer rates that includes the calculated correct answer rates.

[0229] For example, in this embodiment, there may be 1st to 10th difficulty classes, and the difficulty levels can be defined so that they become progressively more difficult from the 1st difficulty class to the 10th difficulty class.

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

[0231] The above examples are merely illustrative for illustrative purposes, and various implementations are possible, such as the difficulty levels themselves being formulated using different methods, the difficulty levels being classified into classes that are less or more difficult than the 10th difficulty class, and the predetermined range of correct answer rates for each class also being different.

[0232] In other words, in this embodiment, application 111 can determine the difficulty level of new quiz data by deriving a difficulty class that corresponds to the range of correct answer rates that includes the calculated correct answer rate.

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

[0234] Specifically, in this embodiment, application 111 can convert new quiz data with determined difficulty levels into reference quiz data, and store and manage at least one of the reference quiz data sets, categorized according to predetermined criteria (for example, by artist).

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

[0236] As shown in Figure 5, in this embodiment, application 111 can sort at least one reference quiz data for artist A in order from the data with the highest difficulty level to the data with the lowest difficulty level, based on the correct answer rate.

[0237] For example, in this embodiment, application 111 can sort at least one reference quiz data for artist A in order from a 10th difficulty class, which has a preset correct answer rate range of 0 to 0.1%, to a 1st difficulty class, which has a preset correct answer rate range of 80 to 100%.

[0238] In this embodiment, application 111 can sort data within the same difficulty class from data with a low correct answer rate (in other words, data with a higher difficulty level) to data with a higher correct answer rate.

[0239] For example, the reference quiz data corresponding to serial number 2 shown in Figure 5 belongs to the same difficulty class as the reference quiz data corresponding to serial number 3, but because its correct answer rate is lower, it can be sorted higher than the reference quiz data corresponding to serial number 3.

[0240] In this manner, the application 111 in this embodiment can categorize at least one or more reference quiz data sets by at least one or more artists who have subscribed to the fan platform service, and store them sorted in order of difficulty.

[0241] In other words, an application 111 according to an embodiment of the present invention can perform a simulated test based on a fan platform application and construct a question bank database 240 containing at least one or more reference quiz data stored and categorized according to predetermined criteria.

[0242] • How to provide digital item delivery services based on quiz tests.

[0243] The following describes in detail, with reference to Figures 6 to 9, how an application 111 executed by at least one processor of a user terminal 100 according to an embodiment of the present invention provides a digital item provision service in which an application 111, whose difficulty level is adjusted based on the grade of a digital item (in this embodiment, a quiz test), presents a predetermined quiz (a quiz test) and provides a digital item to a user who answers the quiz correctly.

[0244] In an embodiment of the present invention, at least one processor of the user terminal 100 can execute or run at least one application 111 stored in at least one memory 110.

[0245] Hereinafter, the method by which at least one processor operates to execute the instructions of the application 111 and provide the digital item provision service described above will be abbreviated as "the application 111 performs the operation."

[0246] Prior to the explanation, in this embodiment, application 111 can acquire a new digital item at the user's request via at least one of the following methods: a lottery method, a synthesis method, and an enhancement method.

[0247] Specifically, application 111 can provide a lottery function in which a user pays a predetermined amount of goods, requests a digital item lottery system (designated and / or random in the embodiment), and obtains a new digital item if they pass a quiz test.

[0248] Here, the designated lottery method is a system in which the user specifies the artist for which the digital item is intended, specifies the grade of the digital item to be obtained, applies for the lottery, and if they pass the quiz test, they receive a randomly selected digital item from among several digital items that have the specified artist and / or grade as attributes. The random lottery method is a system in which the user applies for the lottery without specifying an artist or grade, and if they pass the quiz test, they receive a random digital item with an artist and grade whose attributes are randomly determined. In the following explanation, for the sake of clarity, only the designated lottery method will be used as the basis for explanation.

[0249] On the other hand, in the embodiments of the present invention, even without a designated lottery system, it is possible to select a specific digital item and acquire it using a designated purchase system. However, in the case of the designated purchase system, since it is a system in which digital items can be acquired without going through a quiz test, the price of the usage rights can be sold at a higher price than the usage rights of the designated lottery system.

[0250] Furthermore, application 111 according to an embodiment of the present invention can provide a function that allows a user to pay for at least two or more digital items from among those they possess using a synthesis method, request synthesis, and then, if they pass a quiz test, acquire a digital item that is an upgrade from the digital item they paid for.

[0251] Furthermore, application 111 according to an embodiment of the present invention can provide a function in which, in an enhancement method, the user pays a predetermined price (e.g., goods, enhancement items, etc.) with digital items they already possess, and if they pass a quiz test, they can acquire a digital item that is an upgrade from the digital item they already possessed and paid for.

[0252] In the case of synthesis and enhancement methods, the system replaces the digital item paid with a digital item of a higher grade than the one already matched, and regardless of whether the synthesis and enhancement are successful or unsuccessful, the paid digital item may be burned.

[0253] In such a synthesis and enhancement method, certain benefits may be added, such as providing limited edition digital items that cannot be obtained through the lottery method, or allowing the highest grade of digital items obtainable through the unenhanced synthesis method to be higher than the highest grade of digital items obtainable through the lottery method, since the digital items paid for are incinerated.

[0254] Furthermore, the quiz test presented when acquiring and / or upgrading digital items based on the lottery / synthesis / enhancement method according to the embodiment may include at least one quiz item, and an equal number and / or grade of digital items can be provided depending on the quiz results.

[0255] Figure 6 is a flowchart illustrating a method for providing digital items using a lottery system according to an embodiment of the present invention.

[0256] First, referring to Figure 6 to illustrate the method of providing digital items using a lottery system, in this embodiment, application 111 can sense user input to select the digital item to be acquired. (S301)

[0257] Specifically, in this embodiment, application 111 can sense user input to select the digital item to be acquired from a total of digital items that differ by artist and / or grade.

[0258] For this purpose, at least one digital item can be pre-stored in the digital item database 260, categorized according to predetermined categories.

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

[0260] Furthermore, in the embodiment, the user can select at least one attribute from among the attributes of a digital item and make user input to obtain a single digital item that includes the selected attribute.

[0261] In this case, the selected attribute may be an attribute of a category in the digital item database 260.

[0262] For example, a user can input information to retrieve a single digital item that matches "S-grade" and "A-artist."

[0263] Furthermore, in this embodiment, the user can select only the attributes for the first and second categories from the attributes of the digital item, and input user input to obtain a digital item of package type consisting of any combination of attributes for the third category.

[0264] In this case, the package may specify individual artists and / or groups that fall under the first and second categories, but the grade that falls under the third category may be a product that includes multiple digital items set within a predetermined range.

[0265] For example, a user can enter user input to obtain a digital item package that matches "Artist A" and / or "Group A".

[0266] In this case, the package may include a general package containing multiple digital items matched with "C-grade to S-grade" from among the digital items matched with "A-grade artist" and / or "A-group," and a royal package containing multiple digital items matched with "A-grade to S-grade."

[0267] Furthermore, in this embodiment, the user can purchase the right to determine whether or not the selected digital item is available for acquisition. In this case, the price of the right to use the selected digital item may vary depending on its grade.

[0268] To this end, in this embodiment, application 111 can perform a payment process for purchasing the usage rights. This allows users to purchase usage rights that enable them to acquire digital items via a lottery system by paying a predetermined amount.

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

[0270] For example, if a user selects a single digital item that matches an "S-grade" rating, in one embodiment, the application 111 may set conditions such that the user can only purchase the right to acquire the selected S-grade digital item if they have taken more than 100 practice tests and possess more than 10 digital items of A-grade or higher.

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

[0272] For example, if in step S301 the user requests a lottery based on the attributes of an A-grade digital item from an A-grade artist, the application 111 in this embodiment can be set to allow the user to select one digital item from among the digital items having the attributes of "A-grade artist" and "S-grade".

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

[0274] Referring again to Figure 5, the reference quiz data for the detected artist A can be detected in descending order from the most difficult data to the least difficult data (for example, from the 10th difficulty class to the 1st difficulty class).

[0275] Next, in the embodiment, 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 this embodiment, application 111 can determine the difficulty level of reference quiz data to be presented in a quiz test based on the grade of the digital item obtained from the lottery.

[0277] In this embodiment, application 111 can set a range of reference quiz data that can be presented for each grade (hereinafter referred to as the "question range") from at least one set of reference quiz data, in order to determine the difficulty level of the reference quiz data based on the grade of the acquired digital item.

[0278] For this purpose, at least one or more reference quiz data sets can be pre-stored in the question bank database 240, categorized according to predetermined categories.

[0279] For example, the predetermined categories may include a first category classified by individual artist, a second category classified by artist group, a third category classified by difficulty level, and so on.

[0280] In this embodiment, application 111 can set the scope of questions based on predetermined criteria matched for each grade.

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

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

[0283] Specifically, application 111 can pre-set lottery probabilities for each digital item grade data and determine the difficulty level and / or the number of quiz tests to be presented when selecting an item so as to match the pre-set lottery probabilities. In one embodiment, application 111 can detect quiz tests having difficulty classes with correct answer probabilities corresponding to the lottery probabilities of the selected digital item grade data and provide the detected quiz tests to the user.

[0284] For example, if a request is made for a lottery of SS-grade digital item data, a quiz test of difficulty level 10 with a correct answer probability that matches the probability of winning an SS-grade lottery can be detected and presented.

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

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

[0287] For example, in the embodiment, the application 111 can match values in the upper 0% to 0.1% for the SS grade and values in the upper 80 to 100% 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 sets the upper 0% to 0.1% of the A artist-related reference quiz data in the question range among the A artist-related reference quiz data sorted in ascending order of difficulty in the question bank database 240. It can be determined as the question range.

[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 the data from serial number 800 to serial number 1000, which is the upper 80 to 100% of the reference quiz data, as the question range.

[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, application 111 can determine the difficulty level of reference quiz data to be presented in a quiz test based on predetermined criteria (e.g., predetermined difficulty classes and / or top percent (%) values) matched to the extracted grades.

[0293] In another embodiment, application 111 may also extract multiple quiz tests from the question bank database 240 such that the total probability of correct answers for multiple quiz tests matches the probability of obtaining each achievable digital item. For example, the first and second quiz tests may be extracted and presented to the user such that the total probability of correct answers, obtained by multiplying the probability of correct answers for the first quiz test by the probability of correct answers for the second quiz test, matches the probability of obtaining each item.

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

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

[0296] In this embodiment, the at least one or more reference quiz data randomly determined by application 111 may be singular and / or multiple, but for the sake of explanation, they may be referred to as the first reference quiz data.

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

[0298] To this end, in this embodiment, once a quiz test is executed by user input, application 111 can display multiple data points included in a randomly determined first reference quiz data set in a quiz format as shown in Figure 7 on the display of the user terminal 100.

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

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

[0301] The artist information data 251 provided to the user as part of the quiz test may be data that includes at least one of the following: a photograph, image, audio, and sound source of the artist, depending on the type of question included in the first reference quiz data.

[0302] Furthermore, the artist information data 251 may be omitted if the first reference quiz data, which is randomly determined and presented, is not a question about the artist's photograph, image, audio, or sound source, but simply a question asking for artist-related information in text format.

[0303] Furthermore, problem data 510 can be included once per reference quiz data, regardless of the type of problem in the first reference quiz data.

[0304] Furthermore, the answer data 520 may include multiple examples if it is objective based on the answer type included in the first reference quiz data, or it may include a text box for entering a predetermined text if it is subjective.

[0305] In the embodiment, the user can select at least one example from a plurality of examples, or enter predetermined text.

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

[0307] In addition, the user may be required to register and submit an answer within a predetermined time (e.g., 3 - 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 exclude the possibility of searching and receiving help from others, in an embodiment, the application 111 can set conditions such as blocking the execution state of the application 111 from being 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] In addition, 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 digital items to be awarded to the user, including the availability, quantity, and grade data of the digital items, and randomly select and award digital items corresponding to the determined attributes 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 adding up the scores preset for each reference quiz data item.

[0313] In this embodiment, if the user correctly guesses the answer, the application 111 can provide the digital item selected in step S301 (S313-1). On the other hand, if the user is unable to guess the answer correctly, the digital item may not be provided (S313-2).

[0314] Furthermore, in this embodiment, if the user correctly answers a predetermined number of reference quiz data, the application 111 can also provide the user with digital items of different grades from the artist's digital items selected in step S301, based on the calculated total score.

[0315] In an embodiment, to provide digital items of different grades based on the calculated total score, application 111 can pre-set a predetermined total score criterion.

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

[0317] Additionally, if the calculated total score is between 80 and 100 points, a digital item one rank lower than the selected rank may be randomly provided.

[0318] Additionally, if the calculated total score is between 60 and 80 points, a digital item two ranks lower than the selected rank may be randomly provided.

[0319] If there are no digital items of one grade lower and / or two grades lower (for example, if the grade of the digital item selected in step S301 is grade C), the lowest grade digital item available may be randomly provided.

[0320] The aforementioned randomly provided digital items are random only in their rank; the matching artist may be the same.

[0321] Furthermore, if the calculated total score is less than 60 points, it will be considered that the user failed to guess the correct answer, and the digital items paid for may be forfeited, and no new digital items may be provided.

[0322] Furthermore, in this embodiment, if the user correctly answers a predetermined number of reference quiz data, the application 111 can determine the number of digital items of a different grade from the digital items of the artist selected in step S301 based on the calculated total score, and provide the user with the determined number of items.

[0323] Furthermore, if a first reference quiz data of the highest difficulty level (e.g., top 0.1%) is presented in step S309, and the user correctly answers the question and obtains the highest-ranking digital item after steps S311 and S313-1, the application 111 may, in this embodiment, delete or modify the first reference quiz data from the question bank database 240 so that the first reference quiz data is not presented again.

[0324] Conversely, if the user is unable to correctly answer the first reference quiz data of the highest difficulty level, the first reference quiz data can be retained in the question bank database 240 so that it may be presented again in the quiz test, rather than being deleted.

[0325] This could be to reduce the likelihood of the highest-ranking digital items being easily provided, while maintaining the quiz quality of reference quiz data corresponding to the highest difficulty level.

[0326] After the steps described above, application 111 according to the embodiment of the present invention can provide a digital item of the attribute that the user wishes to acquire.

[0327] In addition, in this embodiment, application 111 can adjust the difficulty level of the reference quiz data by comparing the distribution rate for each digital item grade data of at least one or more reference quiz data that have undergone a quiz test with the acquisition rate for each digital item grade data that has been set in advance.

[0328] In this embodiment, application 111 can adjust the quantity of digital items provided for each difficulty level and adjust the rate at which digital items are provided through the difficulty level adjustment.

[0329] To this end, in this embodiment, application 111 can determine the number of digital items provided to users by grade.

[0330] Furthermore, in this embodiment, application 111 can change the difficulty level matched to each grade based on the number of items determined according to pre-set criteria for each grade.

[0331] Specifically, in this embodiment, if the number of items obtained exceeds a preset standard for the first grade, application 111 can adjust the quantity supplied by increasing the difficulty level matched to that grade, making it more difficult for the user to obtain the digital items.

[0332] For example, assuming that there are 100 pre-set criteria for S-grade items, if the number of S-grade digital items provided to the user exceeds 100, the application 111 in this embodiment can raise the difficulty class matched to S-grade to mitigate the risk of S-grade rarity decreasing.

[0333] In addition, in the embodiment, if the number of items obtained exceeds a predetermined standard for the first grade, application 111 can also adjust the supplied quantity by increasing the number of reference quiz questions belonging to that grade, thereby making it more difficult for the user to obtain the digital items.

[0334] For example, in the same example, application 111 can increase the number of S-grade questions presented when a user takes a quiz test to obtain an S-grade digital item from three to five.

[0335] In other words, in this embodiment, application 111 can adjust the difficulty level of the reference quiz data presented in the quiz test upwards by changing the difficulty class matched to the first grade based on the number of items identified, or by increasing the number of questions in the reference quiz data belonging to the first grade, thereby lowering the user's probability of acquiring digital items and adjusting the quantity for each grade.

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

[0337] To this end, in this embodiment, if the digital item supply rate exceeds a predetermined acquisition rate standard for a digital item grade, application 111 can modify and present questions from the reference quiz data.

[0338] In other words, the question part of the reference quiz data has a content area set up to adjust the difficulty level, and if difficulty adjustment is necessary, the difficulty level can be increased or decreased by changing the content area set up in the reference quiz data.

[0339] Specifically, in this embodiment, application 111 can adjust the difficulty level of the first reference quiz data by changing the exposure range of artist information data included in the first reference quiz data when the distribution rate of digital items exceeds a predetermined standard.

[0340] For example, application 111 can increase the difficulty of the first reference quiz data by reducing the exposure range of the images and pictures of artist A included in the first reference quiz data, or by reducing the playback time of the audio and sound sources. Similarly, it can decrease the difficulty of the first reference quiz data by increasing the exposure range of the images and pictures, or by increasing the playback time of the audio and sound sources.

[0341] In addition, in this embodiment, application 111 can adjust the difficulty level of the first reference quiz data by changing the answer types included in the first reference quiz data where the distribution rate of digital items exceeds the acquisition rate for each digital item grade that has been set in advance.

[0342] For example, application 111 can increase the difficulty of the first reference quiz data by changing the answer types included in the first reference quiz data from objective to subjective, or by increasing the number of objective answer choices. Similarly, it can decrease the difficulty of the first reference quiz data by changing the answer types from subjective to objective, or by reducing the number of objective answer choices.

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

[0344] Specifically, in this embodiment, application 111 can sense user input in which the user selects at least two or more digital items from among the digital items the user possesses that the user intends to combine.

[0345] Here, the synthesis method can be a system that provides a function in which, after a user requests synthesis by paying for at least two or more digital items they possess, and passes a quiz test, they acquire a digital item with an upgraded grade in a smaller quantity than the digital items they paid for. In this embodiment, the user who inputs the selection of digital items to be synthesized can be a user who has purchased the right to perform digital item synthesis.

[0346] Furthermore, when selecting at least two or more digital items to be synthesized in the embodiment, certain conditions may be applied.

[0347] Specifically, in the embodiment, application 111 can apply a condition that requires matching at least one attribute among multiple digital items to be synthesized.

[0348] For example, in one embodiment, application 111 may have multiple digital items input during synthesis that belong to the same artist and / or artist group.

[0349] Furthermore, in this embodiment, application 111 allows multiple digital items input during synthesis to be of the same grade.

[0350] To this end, in this embodiment, when a first digital item is initially input, application 111 can detect a second digital item from among a plurality of digital items held by the user that has attributes matching those of the first digital item, and activate and display the detected second digital item.

[0351] For example, conditions may be set such that at least two digital items must be of the same grade, and the number of digital items to be combined is limited to a maximum of n. In this case, even if, for example, 10 digital items of the same grade are selected for combination, the resulting digital item may be only one.

[0352] In one embodiment, application 111 can perform predetermined steps, described later, to determine whether the synthesis of the selected digital items is successful or not.

[0353] Next, in this embodiment, application 111 can determine predetermined attribute data to be matched with the selected digital item. (S503)

[0354] Specifically, in the embodiment, application 111 can determine predetermined attribute data of the acquired digital items (in the embodiment, artist's personal name, artist's group name, artist's gender, artist's affiliated company, and rank, etc.) based on the synthesis result, so as to be matched with the selected digital items.

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

[0356] To this end, in this embodiment, application 111 can detect a predetermined reference quiz data from among at least one reference quiz data stored in the problem bank database 240 based on the determined attribute item data.

[0357] Next, in this embodiment, application 111 can determine the difficulty level of a digital item based on its grade data, which is obtained from the predetermined attribute data that has been determined. (S505)

[0358] To this end, in the embodiment, application 111 can determine the grade of the digital item obtained via synthesis based on grade data from the predetermined attribute data determined above.

[0359] Specifically, in the embodiment, application 111 can determine the grade of the obtainable digital item to be at least the same grade as the extracted grade data and / or a higher grade than the extracted grade data.

[0360] In another embodiment, application 111 can determine the grade of the digital item obtained upon successful synthesis based on user input from the user selecting the grade. In this case, application 111 can provide the user with the option to select an item that is identical to the extracted grade data or from among the higher grades.

[0361] Once the grade of the obtainable digital item is determined, in an embodiment, application 111 can determine the difficulty level of the reference quiz data that will be included in the quiz test based on the determined grade.

[0362] In this embodiment, the higher the determined grade, the higher the difficulty level of the reference quiz data that is to be included in the quiz test.

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

[0364] The explanation of how to set the scope of questions is the same as in step S305 described above, and can be applied mutatis mutandis. In the same manner, in an embodiment, application 111 can determine the difficulty level of the reference quiz data to be presented in the quiz test based on predetermined criteria matched to the determined grade. Here, predetermined criteria can mean the probability of obtaining a digital item through successful synthesis, or in other words, the probability of successfully synthesizing the digital item to be obtained.

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

[0366] Specifically, in the embodiment, application 111 can determine the target artist of the digital item to be acquired upon successful synthesis based on the predetermined attribute data (in the embodiment, at least one of the following data: artist's individual activity name, artist's group name, artist's gender, and artist's affiliated company data).

[0367] In this case, if the artist's personal name data matches among the predetermined attribute data of each of the multiple digital items, the application 111 can determine the target artist of the acquisitive digital item as the aforementioned artist.

[0368] For example, if the artist's individual activity name data among the predetermined attribute data determined for each of the multiple digital items includes "Artist A," then in this embodiment, application 111 can determine the target artist of the retrievable digital item to be "Artist A." Also, if the artist's individual name data among the attribute data of the multiple digital items differs, but the artist group name data matches, then in this embodiment, application 111 can determine the target artist of the retrievable digital item to be the aforementioned artist group.

[0369] For example, if, among the predetermined attribute data determined above, the individual artist name data is "Artist A" and "Artist B," but the artist group name data is "Group C," then in this embodiment, application 111 can determine that the target artist group for the retrievalable digital item is "Group C."

[0370] In this case, if the target of the obtainable digital item is a group rather than an individual artist, the reference quiz data described later may be a quiz about that group, and the digital item provided upon successful synthesis may also be a digital item for that group.

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

[0372] For example, if the first digital item entered has artist individual activity name data "Artist A" and artist group name data "Group C", and the second digital item entered has artist individual activity name data "Artist B" and artist group name data "Group D", then application 111 can determine that the target artist for the retrievalable digital item is at least one of "Artist A" (individual), "Artist B" (individual), "Group C", and "Group D".

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

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

[0375] In addition, in this embodiment, application 111 can detect reference quiz data in the question bank database 240 that matches the target artist of the available digital items.

[0376] For example, in one embodiment, if the obtainable digital item is an "A-rank" artist of "SS-rank," application 111 can determine the attributes, including the difficulty level, that match the SS-rank associated with "A-rank" and have a correct answer rate of 0% to 0.1%, and then detect the corresponding reference quiz data in the question bank database 240.

[0377] The explanation of the process for determining the reference quiz data presented by the synthesis request is the same as the process for determining the reference quiz data in the lottery, so redundant explanations will be omitted.

[0378] Furthermore, application 111 can randomly determine the quiz data to be presented using multiple detected reference quiz data.

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

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

[0381] A detailed explanation of this is the same as that given in step S309 above, so we will omit it here by applying that same explanation.

[0382] In addition, in this embodiment, application 111 can determine whether the submitted response data is correct or not. (S513)

[0383] In this embodiment, if there are multiple reference quiz data presented as a quiz test, and therefore multiple response data are submitted, the application 111 can determine whether the answer is correct or not, and calculate a total score by summing the points set in advance for each reference quiz data.

[0384] Next, in this embodiment, if the user guesses the correct answer, application 111 can provide one digital item from 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 correctly answers the reference quiz data presented in the quiz test, application 111 can provide one digital item that is matched with a higher grade than the grades of at least two or more digital items selected as synthetic materials in step S501.

[0386] In one embodiment, the digital item provided by successful synthesis may have higher price information contained in the NFT smart contract data than the digital item before synthesis.

[0387] Furthermore, in this embodiment, application 111 can further enhance and upgrade the digital item provided by the successful synthesis, by adding predetermined content to the NFT media data contained in the digital item, or by improving the quality of existing content to increase its scarcity value, thereby increasing the price information contained in the NFT smart contract data.

[0388] On the other hand, in the embodiment, if the user correctly answers a predetermined number of reference quiz data items, the application 111 can provide a digital item of a differential grade based on the calculated total score.

[0389] In an embodiment, to provide digital items of different grades based on the calculated total score, application 111 can pre-set a predetermined total score criterion.

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

[0391] Furthermore, if the calculated total score is between 80 and 100 points, the system can randomly provide digital items of the same grade as at least two or more digital items selected as synthesis materials.

[0392] Furthermore, if the calculated total score is between 60 and 80 points, a digital item one grade lower than the grade of at least two digital items selected as synthesis materials may be randomly provided.

[0393] If no digital item of a lower grade exists (for example, if at least two digital items selected as synthesis materials are of grade C), the lowest grade digital item available may be randomly provided.

[0394] The aforementioned randomly provided digital items are random only in their rank; the matching artist may be the same.

[0395] Furthermore, if the calculated total score is less than 60 points, the user will be deemed unable to guess the correct answer, and at least two or more digital items paid for will be forfeited, and higher-grade digital items resulting from successful synthesis may not be provided.

[0396] Conversely, if the user fails to guess the correct answer, application 111 may burn at least two or more digital items selected for synthesis in step S501. (S515-2)

[0397] In such cases, the application 111, in its embodiment, has the effect of maintaining the scarcity of digital items, including those of a predetermined grade, through incineration if an excessive quantity of those grades is provided to users.

[0398] Figure 9 shows an example of a digital item provided by an embodiment of the present invention.

[0399] As shown in Figure 9, the digital item DI can include at least one of the following content: artist image 710, text 720, and auditory 730.

[0400] In one embodiment, the digital item DI includes an artist image 710 as main content and may further include at least one of text 720 and an audition 730 as sub-content. Specifically, in one embodiment, the first digital item may include at least one sub-content for one main content.

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

[0402] In other embodiments, the text 720 can be numbers and letters displayed overlaid on the artist image 710. For example, it could include the artist's album name, the artist's personal and / or group name, an anniversary, etc. It could also include an image of text written by the artist.

[0403] In addition, in this embodiment, the text 720 may consist of a font specified by the user and / or administrator, or a font that includes the artist's actual typeface.

[0404] In this embodiment, the auditory content 730 can also refer to the content output as audio when a user inputs an affordance for selecting whether or not to output an auditory content on the artist image 710. For example, it may include a voice message consisting of a portion of the artist's sound source and the artist's voice.

[0405] <Digital Items>

[0406] On the other hand, the application 111 according to the embodiment can provide a user interface (UI) for selecting the main content and sub-content constituting the digital item DI in order to generate the digital item DI. Figure 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 grade of the digital item DI through enhancement or synthesis by answering quizzes, and can provide a user interface for generating an upgraded digital item DI that can be modified and generated to suit the user's preferences.

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

[0408] Specifically, in this embodiment, 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] This allows the application 111 in this embodiment to sense the selection of an artist image 710 to be used as the main content of the digital item DI based on user input.

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

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

[0412] The second regions 713-1 and 713-2 can exist in multiple locations due to the clothing (e.g., jackets, underwear, dresses, and shoes) and accessories (e.g., hats and bags) worn by the artist, and the number of such regions is not limited to those shown in the illustration.

[0413] In one embodiment, 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] Furthermore, the attributes of the artist image 710 can also be changed by changing the hue and pattern of the third region 714.

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

[0416] Figure 11 shows 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 Figure 11, in this embodiment, application 111 can sense the selection of at least one text 720 and auditory 730 to be used as sub-content of the digital item DI based on the UI.

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

[0419] As a result, in this embodiment, application 111 can sense the selection of at least one text 720 and auditie 730 to be used as subcontent of the digital item DI based on user input.

[0420] Furthermore, in this embodiment, the application 111 can change the attributes by adding to the number of texts 720 included in the subcontent or by adding a predetermined effect to the text 720.

[0421] Furthermore, in this embodiment, application 111 can change attributes by extending the playback time of the audio 730 included in the sub-content.

[0422] In other words, in this embodiment, application 111 can provide a user interface for selecting the main content and sub-content of a digital item DI, thereby allowing the user to select one image from at least one fixed image and / or moving image, determine the main content by changing the attributes of a predetermined area constituting the selected image, and determine the sub-content by adding at least one text 720 and auditory 730 to be output on the main content, thereby customizing the artist image 710 based on user input.

[0423] Next, the service server 200 according to the embodiment can generate multiple unique digital item DIs formed by combinations of at least one or more texts 720 and auditions 730 output on the artist image 710 which has been customized based on the application 111.

[0424] In other words, the multiple digital item DIs can be unique digital item DIs with a number / type / attributes that are all different in the artist image 710 included in the main content, the attributes of the predetermined areas constituting the artist image 710, the text 720 included in the sub-content, and the auditory 730.

[0425] Furthermore, in this embodiment, the service server 200 can register each of these multiple digital item DIs as an NFT.

[0426] Specifically, in this embodiment, the service server 200 can register each of multiple digital item DIs as a unique NFT by adding NFT metadata including descriptive information, generator information, and storage address information, as well as NFT smart contract data including owner information, transaction history information, condition information, and price information, using blockchain technology.

[0427] In this embodiment, the service server 200 can provide the user with a plurality of digital item DIs registered as NFTs as NFT-based digital items, and can improve the grade of the provided NFT-based digital items through synthesis and enhancement performed in the application 111. At this time, as the grade of the NFT-based digital items is improved, the price information included in the NFT smart contract data is also improved, and the asset value of the digital items may increase.

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

[0429] In this case, the elements that determine 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 and attributes of the text 720 included in the sub-content, and the sound quality and audio playback length of the audio 730.

[0430] In other words, the elements 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 texts 720 in the sub-content, a fifth element for the sound quality of the audio 730 in the sub-content, and a sixth element for the audio playback length of the audio 730 in the sub-content.

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

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

[0433] In this case, the detail steps can range from the first step being the lowest quality / quantity attribute to the tenth step being the highest quality / quantity attribute. Furthermore, the first step can be the step designated as the default.

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

[0435] In addition, in the embodiment, the service server 200 can set the first step to the case where the artist image 710 included in the main content is a static image that does not move, as a second element for the image playback length of the main content, and set the second step to the tenth step to which the image playback length is shortest.

[0436] In addition, in the embodiment, the service server 200 can set a third element for the number of texts 720 in the subcontent, ranging from a first step where there are 0 texts 720 to a tenth step where there are 10 texts 720.

[0437] In addition, in the embodiment, the service server 200 can set a fourth element for the text 720 attribute of the subcontent, ranging from a first step where zero attributes are added to the text 720 to a tenth step where ten attributes are added to the text 720. In this case, the attributes added to the text 720 may include font upgrades, character size upgrades, and the addition of effects (e.g., glow and movement).

[0438] Furthermore, in the embodiment, the service server 200 can set a fifth element for the sound quality of the sub-content's auditory 730, ranging from a first step with the lowest sound quality to a tenth step with the highest sound quality.

[0439] Furthermore, in the embodiment, the service server 200 can set a sixth element for the audio playback length of the sub-content's auditory 730, ranging from a first step with the shortest audio playback length to a tenth step with the longest audio playback length.

[0440] In other words, in this embodiment, the service server 200 can determine a higher grade for an NFT digital item the closer it is to the 10th step in which the main content contained in the NFT-based digital item has the highest resolution, the longest image playback length, the largest number of sub-content texts, the most attributes added to the texts, the highest sound quality of the sub-content audio, and the longest audio playback length.

[0441] Furthermore, in this embodiment, upon successful enhancement, the service server 200 may raise the step of at least one of the steps of the first to sixth elements included in the NFT digital item paid for by the user for enhancement by a predetermined step (e.g., one step and / or one or more steps).

[0442] In addition, in this embodiment, upon successful synthesis, the service server 200 can raise the step of at least one element among the steps of the first to sixth elements contained in at least two NFT digital items paid for by the user for synthesis by a predetermined step (e.g., one step and / or one or more steps). At this time, the steps of each of the first to sixth elements contained in at least two NFT digital items paid for synthesis are the same, and thus the grades can also be the same.

[0443] In this embodiment, the service server 200 may randomly determine at least one of the first to sixth elements whose steps are advanced by the success of the enhancement and synthesis, or it may determine it as a user selection input based on the application 111.

[0444] In this manner, or in other words, in this embodiment, the service server 200 senses an input that the user has paid for at least one NFT digital item for enhancement and / or synthesis, executes a quiz test of varying difficulty levels based on the grade of the at least one NFT digital item that has been paid, and if the results of the executed quiz test meet predetermined conditions, can provide a higher-grade NFT digital item for the at least one NFT digital item that has been paid.

[0445] For example, in one embodiment, the service server 200 can provide a digital item of a higher grade than the one paid for by providing a first digital item with a second resolution if the user pays n digital items with a resolution of the first step as synthesis materials and passes a quiz test to successfully synthesize them.

[0446] In other words, in the embodiment, the service server 200 can provide digital items of a higher grade than the grade matched to the digital items paid for the synthesis and enhancement, by increasing the detail steps for each element that determines the grade.

[0447] For example, in one embodiment, the service server 200 can provide a digital item in which the resolution of the main content included in the paid digital item has been increased or the image playback length has been increased due to successful enhancement and synthesis.

[0448] Furthermore, in this embodiment, the service server 200 can provide a digital item in which the number and attributes of the text 720 have been added to the sub-content included in the digital item paid for through enhancement and synthesis success.

[0449] Furthermore, in this embodiment, the service server 200 can provide a digital item in which the audio playback length of the auditory 730 has been extended from the sub-content included in the digital item paid for by the enhancement and synthesis success.

[0450] On the other hand, in this embodiment, the service server 200 can provide a function to upgrade the digital item by transforming the artist image 710, which is the main content of the digital item, via a generative artificial intelligence model to suit the user's preferences.

[0451] To this end, the service server 200 may include a generative artificial intelligence model that generates artist images 710 of digital items based on user text and sketches.

[0452] Such generative artificial intelligence models can be models that have been further trained with artist images in addition to existing generative artificial intelligence models like stable diffusion, and have learned multiple styles of digital items.

[0453] In other words, the generative artificial intelligence model learns from multiple images of each artist, and can precisely generate artist images based on the artist of the digital item.

[0454] Furthermore, the generative artificial intelligence model can be further trained on the artist's digital items and their style of artist image.

[0455] For example, a generative artificial intelligence model can be trained by designating a first digital item issued to artist A upon the release of album B as style K, and a second digital item issued by artist A upon concert B as style L.

[0456] In other words, generative artificial intelligence models can generate an artist's image that matches the style of the underlying digital item they are trying to enhance / synthesize, along with an upgraded artist image that matches the style of the digital item.

[0457] More specifically, if a user wants to create a new artist image 710 for a digital item through enhancement / compositing, they can first select the artist image 710 modification function via application 111.

[0458] Furthermore, when the user modifies the artist image via application 111, they can guide the transformation of the artist image by attaching text, sketch images, or / or photographs to indicate the desired direction.

[0459] For example, a user can input their own photo into application 111 and a request as text saying, "Generate an image of the person in the photo and the artist performing action A (for example, shaking hands)."

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

[0461] In this case, the service server 200 can maintain the artist attributes of the digital items by providing additional input to the generative artificial intelligence model to generate only the artists of the underlying digital items used for artist synthesis / enhancement.

[0462] Furthermore, the service server 200 can maintain the style of the digital items by providing additional inputs to generate the artist image in the style of the underlying digital items used to composite / enhance the artist.

[0463] Through such a generative artificial intelligence model, users can generate their own digital content in the direction they desire, which is a key need for NFT digital items. At the same time, by maintaining the artist and style attributes of the digital items, it is possible to prevent users from indiscriminately changing the direction in which artists and producers issue digital items.

[0464] As described above, the NFT-based digital item provision method and system according to the embodiments of the present invention have the effect of preventing illegal copying and the distribution of counterfeit goods that falsely represent IP by digitizing content products based on artist IP.

[0465] Furthermore, the NFT-based digital item provision method and system according to the embodiment of the present invention has the effect of eliminating the possibility of probability manipulation by presenting a quiz about the artist and providing a digital item according to the quiz result.

[0466] Furthermore, the digital item provision method and system based on NFTs according to the embodiment of the present invention have the effect of reducing the gambling aspect by presenting quizzes of varying difficulty levels depending on the grade of the digital item and adjusting the success rate of lottery / enhancement / synthesis.

[0467] Furthermore, the NFT-based digital item provision method and system according to the embodiment of the present invention has the effect of maintaining the rarity of the digital item by applying a reasonable difficulty level to the grade of the digital item, thereby managing the difficulty level based on the success rate of acquiring the digital item through the presentation of quizzes.

[0468] Furthermore, the NFT-based digital item provision method and system according to the embodiment of the present invention have the effect of improving fan satisfaction by providing digital items that reflect the preferences of fans, and also encouraging high fan participation.

[0469] The embodiments of the present invention described above can be implemented in the form of program instructions that can be executed through various computer components and recorded on a computer-readable recording medium. The computer-readable recording medium may include program instructions, data files, data structures, etc., individually or in combination. The program instructions recorded on the computer-readable recording medium may be specifically designed and configured for the present invention, or may be publicly known and available to 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 instructions, such as ROMs, RAMs, and flash memory. Examples of program instructions include not only machine code, such as that produced by a compiler, but also high-level language code that can be executed by a computer using an interpreter or the like. Hardware devices can be modified into one or more software modules to perform the processing according to the present invention, and vice versa. [Industrial applicability]
