Description

System and method for providing a learning curation service using learning map-linked open badges

[0001] The present disclosure relates to a system and method for providing a learning curation service utilizing a learning map-linked open badge.

[0002] Due to the development of internet services, most people use numerous online services through the internet, such as government agencies, educational institutions, medical institutions, telecommunications companies, financial companies, passenger transport companies, asset management, credit information, portals, social network services (SNS), games, shopping, ticketing, courier services, and electronic voting.

[0003] Therefore, users who wish to use such services must register as members by entering personal information, including their real name, or authenticate that they are registered users by entering a specific ID and password. However, since repeating this authentication process on multiple sites is quite cumbersome, methods known as simplified authentication have recently been developed to facilitate easier login and enable financial transactions on the internet.

[0004] Previously, user authentication was performed using a centralized ID (Identify) system. Typically, this involved installing accredited certificates and Active X programs to utilize them, or installing separate applications to perform authentication.

[0005] However, in the case of a centralized identity verification system, there are problems regarding the leakage and misuse of personal information.

[0006] Furthermore, when performing user identity verification using the aforementioned programs or applications, there is the inconvenience of having to install a separate program, and there are compatibility issues with existing applications or programs, which results in problems where user identity verification is not performed smoothly.

[0007] Recently, Decentralized IDentifiers (DID) technology, which allows users to verify their identity through an issuing authority, is gaining attention.

[0008] Meanwhile, Open Badges have recently emerged as a new digital credential method utilizing blockchain technology. These Open Badges embed metadata—such as an individual's learning history, skills, knowledge, reputation, experience, and competencies—into a unique image. By capturing and recognizing a wide range of learning outcomes and enabling verification via blockchain, they effectively enhance the reliability of those results. In essence, Open Badges serve as a standardized framework for sharing badges, ensuring trustworthiness by establishing credentialing, issuance security, and authentication systems for evaluations.

[0009] Therefore, there is a need to develop technology that enables users (learners) to prove their competencies acquired through education, learning, exams, etc. provided by educational institutions (learning institutions) through open badges, as well as to expand those competencies by utilizing open badges.

[0010] The present disclosure provides a system and method for providing a learning curation service utilizing a learning map-linked open badge, which enables a user (learner) to prove their qualifications acquired through education, learning, exams, etc. provided by an educational institution (learning institution) by conveniently issuing and providing a blockchain-based open badge linked to a learning map. This ensures security while relieving the user of the burden of having to visit the educational institution or its website to obtain certificates of completion, etc., and to submit them directly to a requesting institution (submitting institution), thereby reducing both the time required and incidental costs.

[0011] Meanwhile, the present disclosure provides a system and method for providing a learning curation service utilizing a learning map-linked open badge, which enables a user to manage at least one open badge issued to them in an integrated manner, thereby allowing for convenient verification of their fragmented history data, and enables them to post this data on at least one social network service (SNS), thereby allowing for quick and easy utilization for employment or further education.

[0012] Meanwhile, the present disclosure provides a system and method for providing a learning curation service utilizing a learning map-linked open badge, which enables users to gradually and systematically expand their capabilities by providing a learning curation service using an open badge based on a learning map.

[0013] The problems that this disclosure aims to solve are not limited to those mentioned above, and other unmentioned problems will be clearly understood by a person skilled in the art from the description below.

[0048] The operating principles and embodiments of the present disclosure will be described below with reference to the attached drawings.

[0049] FIG. 1 is a diagram showing the network structure of a learning curation service providing system utilizing a learning map-linked open badge according to one embodiment of the present disclosure, and FIG. 2 is a diagram showing the procedure for providing a learning curation service utilizing a learning map-linked open badge according to one embodiment of the present disclosure.

[0050] Referring to FIG. 1, a learning curation service providing system utilizing a learning map-linked open badge according to one embodiment of the present disclosure (hereinafter referred to as the "service providing system") (1000) may be configured to include a user terminal (100), a first institution terminal (200), a learning curation service providing device utilizing a learning map-linked open badge (hereinafter referred to as the "service server") (300), and a second institution terminal (400). Here, the first institution terminal (200) and the second institution terminal (400) are each depicted as one, but this is for convenience of explanation only and does not limit the number or type thereof. Meanwhile, for convenience of explanation, a learning institution is described as an example below, but any institution that provides a course for acquiring qualifications, such as learning, education, or work, to a user is applicable and is not limited thereto.

[0051] A user terminal (100) is a terminal of a user (Recipient) who acquires qualifications related thereto by performing learning, education, work, etc. provided by at least one first institution based on each first institution terminal (200), and performs DID user registration by registering the issuer's distributed ID information on a blockchain (trusted ID store) through a service server (300) to receive a learning curation service. At this time, when performing DID user registration, the user, i.e., the user's identity, is verified through one of a plurality of authentication methods while issuing an initial distributed ID. Here, the plurality of authentication methods correspond to integrated authentication and may include at least one of biometric authentication, PIN number, and pattern.

[0052] Meanwhile, when a user possessing a user terminal (100) acquires qualification and requests the service server (300) to issue an open badge containing an assertion including performance information as a result of performing learning, education, work, etc. provided by the first institution terminal (200), the service server (300) issues the open badge in response. Meanwhile, the issued open badge may be submitted or displayed to a second institution terminal (400) that requires it, upon the request of the user terminal (100).

[0053] Meanwhile, the first institution terminal (200) is a device or server equipped (installed) at the learning institution and may provide a separate web page or platform (application) to provide the learning service. That is, the first institution terminal (200) may build and provide a separate web page or platform (application), and based thereon, provide the learning service requested by at least one user terminal (200) registered for the learning service.

[0054] This first institution terminal (200) stores and manages not only the user's information but also the history information regarding learning. Here, the user information includes at least one of the user's name, age, gender, address, contact information, and educational background, and the history information may include at least one of login information including login history, admission information for the user (admission year, department, student ID number, etc.), major information, lecture information (semester information, lecture code, classification code, course registration information, curriculum, lecture content, completion status, credits earned, etc.), learning process information (student ID number, course code, completion status, etc.), inquiry information (question name / question content, response name / response content, etc.), assignment information, grade information, and evaluation information (evaluation results such as proficiency, competence, talent, etc.).

[0055] Additionally, the first institution terminal (200) provides a corresponding learning service in response to a request from the user terminal (100), and when the user completes all learning processes for a specific learning through the user terminal (100), it grants the user qualification corresponding to the learning process by receiving the results of the learning process. At this time, the first institution terminal (200) can create new history information for the user or update previously created history information based on the results of the learning process.

[0056] Thus, when the first institution terminal (200) is directly or indirectly requested by the user terminal (100), service server (300), and demand institution (400) to verify the eligibility of the user or to verify whether the user is qualified to receive an open badge, it can verify the eligibility based on the user information and history information and provide a response. At this time, the first institution terminal (200) can verify whether the user satisfies the requirements necessary to acquire an open badge based on the previously stored criteria, and if satisfied, provide badge issuance data extracted from some history from the history information to the service server (300). However, this is merely an example, and the history information of the user may be provided to the service server (300) as is without the need to extract badge issuance data from the history information.

[0057] Here, the first institution terminal (200) may be at least one, and each first institution terminal (200) may be linked (interconnected) with the service server (300) through an API (Application Programming Interface) so that a system, form, etc. regarding a certificate, certificate, etc. that can be issued by each first institution (learning institution, educational institution, etc.) may be stored together.

[0058] Meanwhile, the service server (300) can perform operations such as managing badge issuance data, registering and managing badge issuing organizations, providing badge standard guides, establishing a badge operation framework, verifying badge issuing organizations and badge issuance history, and providing badge issuance data information. Here, the badge issuance data may be data extracted from history information stored and managed by the first institution terminal (200) as data for badge issuance. However, this is merely one embodiment, and the service server (300) may receive the user's history information as is, and is not limited thereto.

[0059] The service server (300) issues an open badge based on badge issuance data or history information, and then registers the badge issuance data on the blockchain for management. At this time, the badge issuance data or history information includes a public key used to sign a claim by the first institution terminal (200). This public key can be used later during DID verification. In addition, the service server (300) may revoke the open badge. At this time, the method required for revocation varies depending on whether the claim is a hosted claim or a signed claim.

[0060] Meanwhile, when the service server (300) issues an open badge, it verifies (measures) at least one of the user's learning unit, proficiency, competence, and talent based on badge issuance data or history information and issues the open badge.

[0061] In other words, Open Badges contain metadata such as the user's achievements and capabilities within the badge image, which can be verified anytime and anywhere. Here, the metadata can be based on the minimum metadata typically recorded on standard digital badges. For example, mandatory metadata may include at least one of first institution data (issuer name, issuer address, issuer description, whether the issuer is accredited, etc.), badge class (course name, accredited course status, characteristics / level of accredited course, course category, characteristics / level of course, completion / qualification criteria, qualification quality assurance type, etc.), acquisition data (completion / qualification, badge issuance date, badge expiration date, evaluation type, form of participation in learning activities, etc.), recipient (recipient name, recipient information, etc.), and verification information (verification URL, etc.), and optional metadata may include at least one of additional information about the issuer, course completion criteria / cycle, proof material URL, withdrawal / reason for withdrawal, possibility of integration with other badges, other service purpose information, prerequisite learning requirements for course registration, evaluation process, acquired score, connectivity with other courses, characteristics of qualifications generated by integration / accumulation with other courses, and position on a learning motfolio / career path.

[0062] Such metadata may be used by the issuer or issuer to verify it upon request from an acquirer or user due to closure, loss, or damage to the data.

[0063] Additionally, the service server (300) stores and searches smart contract-based blockchain data for open badges. At this time, actual data blocks can be organized into a single file form using a data block allocation table linked to a data registration transaction, and the data meta information and the data block allocation table can be cached to improve data search performance. Additionally, actual data blocks can be organized into a single file form using a data block allocation table linked to a data registration transaction, and the data meta information and the data block allocation table can be cached to improve data search performance. To this end, data is encrypted based on unique information generated by the smart contract, and the encrypted data is applied to automatically obtain a decryption key according to access control authority.

[0064] To this end, the service server (300) may build and provide a separate web page or platform (application), and based on this, each device (user terminal, issuing institution terminal, demand institution terminal, etc.) registered for the learning curation service can receive the learning curation service.

[0065] A dashboard for each user may be configured on this web page or platform, and the status of at least one open badge, i.e., DID, issued to each user may be configured in a portfolio form on the dashboard. Through this, the user can execute the web page or platform through the user terminal (100) and check various information regarding at least one open badge issued to them through their DID status.

[0066] This service server (300) can perform DID registration, open badge issuance, DID verification, etc. for a user based on the linked API (Application Programming Interface) (500).

[0067] Meanwhile, the service server (300) generates and provides learning curation information for the issued open badge based on the previously stored curriculum information. At this time, the service server (100) may perform the learning curation information upon the request of the user terminal (100), or it may be performed immediately once the open badge is issued. Accordingly, the service server (100) may provide the learning curation information independently, but it may also be provided by being included in the issuance information of the open badge, and the method or form of provision is not limited.

[0068] Meanwhile, the second institution terminal (400) is a device (terminal) provided (installed) at the demand institution (Consumer), and when an open badge is submitted or displayed from the user terminal (100), it can request the service server (300) to verify the claim digitally signed on the open badge based on the public key so that DID verification can be performed.

[0069] Accordingly, when verification is completed by the service server (300), it can be determined whether to recognize the user's qualification for the corresponding open badge based on the verification result.

[0070] Meanwhile, the user terminal (100), the first institution terminal (200), and the second institution terminal (400) may be a computer, UMPC (Ultra Mobile PC), workstation, netbook, PDA (Personal Digital Assistants), portable computer, web tablet, wireless phone, mobile phone, smartphone, pad, smart watch, wearable terminal, e-book, PMP (portable multimedia player), portable game console, navigation device, black box or digital camera, or other mobile communication terminal, etc., capable of installing and running a number of applications (i.e., applications) desired by the user / first institution (educational institution, learning institution, etc.) / demand institution (demand user, submission place, etc.). At this time, the user terminal (100), the first institution terminal (200), and the second institution terminal (400) may be provided in various forms and are not limited thereto.

[0071] As described above, the service providing system (1000) according to the present disclosure can be implemented through data transmission and reception between a user terminal (100), a first institution terminal (200), a service server (300), and a second institution terminal (400).

[0072] Meanwhile, although not illustrated in FIGS. 1 and 2, the service providing system (1000) may be connected to other external servers, for example, it may be configured to include at least one learning server, at least one search server, etc. For example, the learning server may be a server for providing learning services based on online or offline, and the search server may be a server for providing information search services.

[0073] FIG. 3 is a flowchart illustrating the operation of a learning curation service providing system utilizing a learning map-linked open badge according to one embodiment of the present disclosure.

[0074] Referring to FIG. 3, a user terminal (100) transmits a request for the provision of a learning service to a first institution terminal (200) to receive a learning service from a first institution (S101). At this time, if the user is a new user, the request for the provision of a learning service may be a request for subscription to the learning service, and if the user is a subscribed user, it may be a request for the provision of a specific learning among at least one learning service.

[0075] Next, the first institution terminal (200) checks the request information according to step S101 (S103), checks whether the user has access rights to determine whether to provide the learning service, and then provides the requested learning service only to the accessible user (S105).

[0076] Next, the user terminal (100) performs the learning service provided by the first institution terminal (200), and when the learning service is fully performed, it transmits the results of the learning performance to the first institution terminal (200) (S107).

[0077] Next, the first institution terminal (200) creates new history information for the user or updates previously created history information based on the learning performance results received by step S107 (S109).

[0078] Subsequently, the user terminal (100) sends a DID user registration request to the service server (300) to receive a learning curation service (S111), and the service server (300) performs DID user registration by registering the user's distributed ID information on a trusted ID store, i.e., a blockchain (S113). At this time, the user's DID electronic wallet may be created.

[0079] Next, when the user terminal (100) wishes to receive an open badge, it transmits a request for open badge issuance to the service server (300) (S115). At this time, although not shown in FIG. 3, when the user terminal (100) requests open badge issuance, it may receive at least one open badge that it can be issued from the service server (300) in the form of a list (hereinafter referred to as the 'list of available open badges'). That is, the user can transmit a request for issuance by selecting any one of the open badges from the list. To this end, the service server (300) may perform the operation of registering at least one first institution terminal (200) in advance, and can verify at least one open badge that each user can receive through the history information of each user from the registered at least one first institution terminal (200). Meanwhile, as another embodiment, the service server (300) may recommend issuing open badges that can be issued in addition to the open badge requested by the user, or recommend other learning associated with the previously issued open badge to support the acquisition of eligibility for additional open badge issuance.

[0080] Next, the service server (300) checks the request information according to step S115 (S117) and requests the first institution terminal (200) to verify the user's qualification for the open badge for which issuance has been requested by sending a qualification verification request (S119).

[0081] Next, the first institution terminal (200) checks the user's history information in accordance with the request in step S119, extracts data for badge issuance, i.e., badge issuance data, from the history information (S121), and transmits it to the service server (300) (S123).

[0082] Next, the service server (300) issues the requested open badge based on the badge issuance data according to step S123 (S125), and transmits issuance information including the issued open badge to the user terminal (100) (S127).

[0083] Thus, the user terminal (100) can store the open badge included in the issuance information (S129) and, if necessary, post the open badge on at least one SNS installed on the user terminal (100).

[0084] Next, the service server (300) generates learning curation information using the open badge issued in step S125 (S131) ​​and provides it to the user terminal (100).

[0085] Thus, based on the learning curation information received through the user terminal (100), the user can sequentially learn at least one other learning related to the learning that they have already completed.

[0086] Afterwards, the user terminal (100) generates submission information including the open badge stored in step S129 to submit the open badge corresponding to the qualification to a second institution where the user wishes to have their qualification recognized (S135), and transmits the submission information to the second institution terminal (400) (S137).

[0087] Next, the second institution terminal (400) checks the submission information (S139) and requests the service server (300) to verify the open badge included in the submission information (S141).

[0088] Thus, the service server (300) performs verification of the open badge in accordance with the request in step S141 (S143), generates verification result information including the verification result, and transmits it to the second institution terminal (400) (S145).

[0089] Next, the second institution terminal (400) checks the verification result information received by step S145 and determines whether to recognize the qualification of the user (S147).

[0090] Meanwhile, steps S131 through S133 illustrated in FIG. 3 can be performed at any time after step S125, and the provision conditions may be set in advance by an administrator or user of the service server (100) and provided automatically, or provided by a request from a user through a user terminal (100). That is, steps S131 through S133 can be performed independently after an open badge has been issued.

[0091] FIG. 4 is a diagram illustrating the concept of a learning map-linked open badge according to one embodiment of the present disclosure.

[0092] First, the open badge (600) can be issued, acquired, and managed through an open badge platform that supports the open badge standard. As illustrated in FIG. 4, the open badge (600) contains information regarding the content of the guaranteed skill, issuer information, user information acquired and posted, expiration date, and method for verification. The open badge (600) can also be approached from an ecosystem perspective, and key stakeholders can be classified into three types: the issuing organization that issues the open badge (600), the user who acquires the badge, and the company that develops the open badge platform.

[0093] First, the issuance of such open badges (600) will be determined by qualification granted by a learning institution, and such a learning institution can divide learning into small chunks and provide it to the user, recognize the learning according to proficiency, grant qualification for issuing open badges as a recognition of microcredentials, and measure and maintain the user's ability (talent, qualification).

[0094] Additionally, a user who has been issued an open badge (600) may submit (present) the open badge (600) as proof of skills or academic achievements acquired for the purpose of advancing to a higher school or seeking employment, claim the open badge when it is issued to the user, collect the open badge (600) in a portfolio or backpack to share their story, and share their open badge (600) with social media or communities. That is, the open badge (600) may be posted on at least one social network service upon the request of the user terminal (100).

[0095] In addition, companies seeking business opportunities can design a system that recognizes and verifies small learning units provided by learning institutions, track user participation levels and expand resources, develop tools to issue and display / host open badges (600), apply open badge standards, and obtain conformity certification.

[0096] Meanwhile, the open badge (600) includes an issuer, a badge class, and an assertion, wherein the assertion may include performance information regarding the history performed by the user.

[0097] FIG. 5 is a diagram showing the configuration of a service server that provides a learning curation service using a learning map-linked open badge according to one embodiment of the present disclosure.

[0098] Referring to FIG. 5, a service server (300) providing a learning curation service utilizing a learning map-linked open badge according to one embodiment of the present disclosure may be configured to include a communication module (310), a memory (320), and a processor (330).

[0099] The communication module (310) performs wired or wireless communication with at least one of the user terminal (100), the first institution terminal (200), and the second institution terminal (400), as well as at least one external device (server, etc.), an external storage (e.g., a database (140)), an external server, and a cloud server. In particular, when performing wireless communication, it transmits and receives wireless signals in a communication network according to wireless internet technologies.

[0100] Meanwhile, an external server or cloud server may be configured to perform at least a part of the role of the processor (330). That is, the performance of data processing or data operations, etc., can be performed on an external server or cloud server, and the present disclosure does not impose any special restrictions on such a method.

[0101] The communication module (310) may include one or more components that enable communication with an external device, for example, may include at least one of a wired communication module, a wireless communication module, and a short-range communication module, and transmit and receive signals based thereon.

[0102] Here, the wired communication module may include various wired communication modules such as a Local Area Network (LAN) module, a Wide Area Network (WAN) module, or a Value Added Network (VAN) module, as well as various cable communication modules such as USB (Universal Serial Bus), HDMI (High Definition Multimedia Interface), DVI (Digital Visual Interface), RS-232 (recommended standard), power line communication, or POTS (plain old telephone service).

[0103] In addition to Wi-Fi modules and WiBro (Wireless broadband) modules, the wireless communication module may include wireless communication modules that support various wireless communication methods such as GSM (global System for Mobile Communication), CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), UMTS (universal mobile telecommunications system), TDMA (Time Division Multiple Access), WLAN (Wireless LAN), DLNA (Digital Living Network Alliance), WiBro (Wireless Broadband), WiMAX (World Interoperability for Microwave Access), HSDPA (High Speed ​​Downlink Packet Access), HSUPA (High Speed ​​Uplink Packet Access), LTE (Long Term Evolution), 4G, 5G, and 6G.

[0104] A short-range communication module is for short-range communication and can support short-range communication by using at least one of Bluetooth, RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, and Wireless USB (Wireless Universal Serial Bus) technologies.

[0105] Specifically, the communication module (310) can receive requests for the issuance, authentication, etc. of an open badge from each of the user terminal (100), the first institution terminal (200), and the second institution terminal (400) based on wired or wireless communication, and transmit the results thereof. In addition, various information for the issuance, authentication, etc. of the open badge can be transmitted and received with the user terminal (100), the first institution terminal (200), and / or the second institution terminal (400) through the communication module (310). Furthermore, the communication module (310) transmits and receives various other information with at least one external device.

[0106] The memory (320) stores data and / or various information that supports various functions of the service server (300). It can store a number of application programs (or applications) running on the service server (300), data for the operation of the service server (300), and commands. At least some of these application programs may be downloaded from an external server via wireless communication. Meanwhile, the application program may be stored in at least one memory provided in the memory (320), installed on the service server (300), and driven to perform an operation (or function) by at least one processor provided in the processor (330).

[0107] Meanwhile, at least one memory may include a storage medium of at least one type among flash memory type, hard disk type, multimedia card micro type, card type memory (e.g., SD or XD memory, etc.), RAM (Random Access Memory), SRAM (Static Random Access Memory), ROM (Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory), magnetic memory, magnetic disk, and optical disk. In addition, the memory may store information temporarily, permanently, or semi-permanently, and may be provided as an embedded or removable type.

[0108] The memory (320) may be equipped with a database (340) for providing a learning curation service, and the database (340) may store various information regarding each of at least one user (user, educational institution, receiving institution, etc.) subscribed to the learning curation service. Additionally, the memory (320) may store at least one process for providing a learning curation service.

[0109] The processor (330) may be equipped with at least one processor for providing a learning curation service and may control all components within the service server (300) to process input or output signals, data, information, etc., or execute instructions, algorithms, and applications stored in at least one memory to perform various processes.

[0110] That is, the processor (330) controls all operations performed by the service server (300) described above based on FIGS. 1 and FIGS. 2.

[0111] Specifically, when the processor (330) receives a request for the issuance of an open badge from a user terminal (100), it determines whether to issue the open badge by checking whether the user has the qualification to issue the requested open badge. Subsequently, when the issuance of the open badge is completed according to the decision, the processor (330) records and manages the issued open badge on the user's DID electronic wallet registered on the blockchain.

[0112] Meanwhile, the processor (330) generates and provides learning curation information for the issued open badge based on the previously stored curriculum information.

[0113] In this case, the pre-stored curriculum information includes a competency framework for each curriculum, wherein at least one related competency framework may be interconnected. Additionally, the competency framework includes a learning map in which at least one competency item included in the curriculum is structured and sequentially connected in the order of learning stage, learning area, learning topic, and achievement standard, wherein at least one related competency item may be interconnected. Here, a competency item represents a learning objective or learning competency, includes learning content, and may be configured to include at least one sub-competency item.

[0114] Furthermore, the processor (330) may collect user learning information from at least one learning institution and, by further considering this, generate specialized learning curation information that is more suitable for the user. Here, the learning information may include at least one of the learning level, learning history, test history, learning results, test results, learning time, learning rate, and progress rate during a pre-set period. For example, the processor (330) may determine whether to proceed to a higher learning stage or a lower learning stage by judging whether the user's learning is excellent or poor based on at least one variable included in the learning information, even if the user is in the first grade of elementary school. Additionally, the processor (330) may decide to repeat the same learning stage if the learning time required for the user to obtain an open badge is greater than the average learning time. In this case, since a long learning time may indicate that the user has lost interest in learning, the processor may search for popular learning content corresponding to the learning stage from at least one search server and provide information about that popular learning content in the learning curation information. Here, popular learning content can be determined based on factors such as views, chat activity, repeat viewing counts, and likes. However, this is merely one example; learning curation information specialized for users can also be generated by utilizing a combination of at least one variable.

[0115] Meanwhile, when the processor (330) receives a DID user registration request from the user terminal (100), it issues an initial distributed ID and verifies the user identity through integrated authentication (biometric authentication, PIN number, pattern) to perform DID registration on the blockchain.

[0116] Meanwhile, when the processor (330) receives a request for the issuance of an open badge for the user from the user terminal (100), it performs user authentication by accessing a distributed ID based on one of a plurality of authentication methods, and then provides a list of issuable open badges including at least one open badge that can be issued to the user. When any of the open badges is selected, the processor issues the open badge by verifying and combining history data and forms based on the user's DID electronic wallet registered on the blockchain.

[0117] Additionally, when the processor (330) receives a request for DID verification for a previously issued open badge from a user terminal (100) or a second institution terminal (400), it accesses the distributed ID based on one of the multiple authentication methods to perform user authentication, and performs DID verification for the previously issued open badge based on the user's DID electronic wallet registered on the blockchain.

[0118] At this time, when the processor (330) performs DID verification, it can verify the badge issuance data using the hash value of a previously issued open badge (an open badge for which DID verification is requested) and the hash value of an open badge previously registered in the blockchain. Here, the hash value of a previously issued open badge can be obtained based on the public key used to sign the claim digitally signed on the open badge.

[0119] This processor (330) can perform DID verification based on the linked API (Application Programming Interface).

[0120] FIG. 6 is a flowchart illustrating a method for providing a learning curation service using a learning map-linked open badge according to one embodiment of the present disclosure.

[0121] Referring to FIG. 6, the user performs DID user registration on the blockchain to the service server (300) by sending a DID user registration request using a user terminal (100) to receive a learning curation service (S210).

[0122] Next, when the user terminal (100) selects an issuance item and requests the issuance of an open badge, the service server (300) performs the issuance of the open badge based on the user's DID electronic wallet through the linked API (S220).

[0123] Next, the service server (100) records the previously issued open badge on the corresponding user's DID electronic wallet registered on the blockchain (S230), and generates and provides learning curation information for the issued open badge based on the previously stored educational course information (S240).

[0124] Additionally, when the service server (300) receives a request for DID verification for an open badge issued from a user terminal (100) or a second institution terminal (400), it performs DID verification for the open badge based on the user's DID electronic wallet through a linked API (S250).

[0125] Here, step S250 is not an action that is necessarily performed and can be performed optionally as needed.

[0126] Meanwhile, although not illustrated in FIG. 6, the service server (300) may perform registration for at least one issuer at step S210 or prior thereto. At this time, the system, form, etc., for qualifications, certificates, etc., granted by each first institution may be stored together.

[0127] FIG. 7 is a diagram showing a specific operation for issuing an open badge in a method for providing a learning curation service using a learning map-linked open badge according to one embodiment of the present disclosure.

[0128] Referring to FIG. 7, when the service server (300) receives a request for the issuance of an open badge for the user from the user terminal (100) (S221), it performs user authentication by accessing the distributed ID based on one of the multiple authentication methods (S222).

[0129] Next, the service server (300) provides a list of available open badges including at least one open badge that can be issued to the user (S223), and when selection information generated by the user selecting one of the open badges through the user terminal (100) is received (S224), the service server performs the issuance of the selected open badge by verifying and combining history data and forms based on the user's DID electronic wallet registered on the blockchain (S225).

[0130] FIG. 8 is a diagram showing a specific operation for generating learning curation information in a method for providing a learning curation service using a learning map-linked open badge according to one embodiment of the present disclosure.

[0131] Referring to FIG. 8, the service server (300) identifies a specific curriculum corresponding to the open badge issued by step S220 from the pre-stored curriculum information (S241).

[0132] Next, the service server (300) detects at least one competency item corresponding to the corresponding learning based on a specific learning map included in the competency framework of the specific curriculum (S242).

[0133] Next, the service server (300) generates learning curation information using at least one competency item detected by step S242 (S243). Specifically, the service server (300) can generate learning curation information by identifying a specific curriculum corresponding to a previously issued open badge in the pre-stored curriculum information, and by detecting at least one competency item corresponding to the learning based on a specific learning map included in the competency framework of the identified specific curriculum.

[0134] Furthermore, the service server (300) can search for learning corresponding to at least one competency item from a database (140) or an external device (server), and provide learning information, learning materials and / or learning content to a user terminal (100) according to the search results.

[0135] FIG. 9 is a drawing of the detailed structure of a competency framework corresponding to each educational course according to one embodiment of the present disclosure.

[0136] Referring to FIG. 9, the competency framework corresponding to each curriculum is a systematically organized set of knowledge and skills that a user must learn. It is a top-level document that defines the curriculum, achievement standards, and competencies included in the pre-stored curriculum information, i.e., the overall curriculum information, and comprehensively covers the competencies / standards of the entire curriculum or specific subjects. All competency skills depend on each competency framework (20), and each competency framework (20) may include at least one competency item (30) below it. Here, the competency framework and the competency item may be referred to as CFDocument and CFItem, respectively.

[0137] Specifically, CFDocument (20) may include CFItems (30), CFAssociations (40), CFRubrics (50), and CFDefinition (60) as components.

[0138] First, CFDocument (20) may include at least one of an identifier, title, creator, URI, subject, description, competencies, and lastChangeDataTime as metadata. Furthermore, CFDocument (20) may include at least one of a subjectURI, language, version, current status, publication start date, publication conversion date, license URI, additional description, and references.

[0139] Table 1 below describes each of the multiple variables that can be included in the metadata of the competency framework (20).

[0140] Variable Type Description Required Identifier UUID Unique identifier Required uri URI Unique address where this CFD can be found on the internet Required creator String Name of the organization that created and approved the competency framework e.g., Office of Education, University, etc. Required title String Title of the CFDocument Required lastChangeDate Time Date Time CFDocument Last modified date and time Required OfficialSource URL RL Web address (URL) of the standard / competency document (source) Option publisher String Name of the organization that publicly publishes and distributes the curriculum / competency document Option description String A brief description of the content of the CFDocument Option subject String List of keywords representing the subject or field of this CFDocument e.g., (Math, Science) Option language ISO 639-2 format string Language in which the content of the CFDocument was written Mainly uses language codes in ISO 639-2 format Option version String CFDocument version information Option adoption Status String CFDocument Last modified date and Time option status Start Date Date CF The date the publication of the Document began option status End Date Date CF The date the publication of the Document ended or was converted to another value option licenseURI LinkURIC F The address of the web document containing license information related to the usage rights of the Document option notesString CF Additional description or reference material for the Document option

[0141] Meanwhile, CFItems (30) are individual items that constitute competencies / standards within CFDocument (20), and represent specific learning content, learning goals, and achievement standards by breaking down CFDocument (20) into smaller units.

[0142]

[0143] Here, CFItems (30) may include multiple CFItems and may be arranged based on the relationship between each CFItem. That is, CFItems (30) may be structured in the order of learning stage, learning area, learning topic and achievement standard and connected step by step, and accordingly may have the form of a learning map.

[0144] At this time, there may be one or more CFItems under CFDocument (20), and CFItems of multiple depths may be added under them.

[0145] CFItems (30) may include at least one of an identifier, a description of competencies and courses (fullStatement), a URI (reference URI for the item), and a last modified time (lastChangeDataTime) as metadata. Furthermore, CFItems (30) may include additional metadata, and the types and number of such data are not limited.

[0146] CFAssociations (40) play an essential role in defining and expressing the relationships between the components of the CFDocument (20), which represent the relationships between the entire curriculum and achievement standards, competency sets, or individual items and courses.

[0147] These CFAssociations (40) can be formed between CFDocuments (20) or between CFItems (30), and can also be formed between CFDocuments (20) and CFItems (30). Additionally, the components connected to the CFAssociations (40) may exist within a single curriculum or may be external components.

[0148] Table 2 below describes the types of relationships related to CFAssociations (40).

[0149] Relationship Type Description isChildOf The source node is a child of the destination node isPeerOf The source node and the destination node are peers isPartOf The source node is logically or semantically included as a part of the destination node's entry exactlyMatchOf The destination node and the source node match exactly Precedes The source node precedes the destination node in time isRelatedTo Used when the source node and the destination node are related but not better described by another type replacedBy The source node is replaced by the destination node Exemplar The destination node is an instance of the source node hasSkillLevel The destination node indicates the skill level of the source node

[0150] In addition, CFRubrics (50) is one of the core elements and is a component that defines how to evaluate whether competency is achieved. It includes evaluation criteria of different grades and is used to describe the quality of learning tasks, works, and learning performance. It defines both the description of evaluation scales and the basis for judging different evaluation grades. At this time, CFRubrics (50) takes a logical matrix structure. Here, the rows of the matrix are used to define evaluation criteria (CFRubricCriterion), and the columns of the matrix are used to define several different levels (CFRubricCriterionLevel) under each evaluation criterion.

[0151] This CFRubric can be composed of CFRubricCriterions and CFRubricCriterionLevels. For example, each CFRubricCriterion has an achievement standard level, and a weight (Rubric Criterion Weight) can be assigned to each level. Additionally, the CFRubricCriterionLevel specifically describes the extent of a student's performance regarding the achievement level, providing a description of each level and assigning a score based on that level.

[0152] Meanwhile, CFRubric is organically linked with other elements, and CFRubricCriterion is connected to CFItem to implement the competencies and achievement standards set in the curriculum as assessment tools and to support the measurement of learners' competency achievement levels.

[0153] FIG. 10 is a drawing showing an example of a competency framework corresponding to a specific educational course according to one embodiment of the present disclosure.
