Description

Methods and systems for supporting the acquisition of compensation for providing information

[0001] The present invention relates to a method and system for supporting obtaining compensation for providing information.

[0002] With the recent rise in interest in Self-Sovereign Identity (SSI), there has been active discussion on how to prove one's eligibility for a desired service using a verifiable credential (VC; abbreviated as "credential" hereafter). This method essentially involves an issuer issuing a digital credential that certifies a specific entity, such as an individual or organization, as possessing a specific qualification. This credential is then presented to a verifier in the form of a verifiable presentation (VP; abbreviated as "presentation" hereafter), which the verifier then verifies.

[0003] As an example of the prior art in this regard, a technology disclosed in Korean Patent Publication No. 10-2023-0143410 can be cited, which is characterized by including the steps of: analyzing the ID issuance history recorded in the decentralized ID management contract in response to a request for issuance of a 'decentralized ID' from a user to inquire whether the user has a decentralized ID already issued; issuing a new decentralized ID to the user if there is no decentralized ID already issued as a result of the inquiry; and, when the new decentralized ID delivered to the user is recorded in the user's electronic wallet, registering the issued decentralized ID in the decentralized ID storage and updating the issuance details of the decentralized ID by recording them in the ID issuance history.

[0004] However, with the above-mentioned conventional technologies and the technologies introduced so far, there is still a lack of means for users to control their own personal information.

[0005] Accordingly, the inventor(s) of the present invention propose a technology that enables user-centered personal information management and utilization by acquiring the target and scope of provision of information generated when a user uses a first VC, providing the generated information to the target based on the scope of provision, and providing compensation to the user in response to the provision of the generated information to the target.

[0038] Hereinafter, various preferred embodiments of the present invention will be described in detail with reference to the attached drawings so that a person having ordinary skill in the art to which the present invention pertains can easily practice the present invention.

[0039] Composition of the entire system

[0040] FIG. 1 is a diagram schematically illustrating the configuration of an entire system for supporting the use of verifiable credentials according to one embodiment of the present invention.

[0041] As illustrated in FIG. 1, the entire system according to one embodiment of the present invention may include a communication network (100), a verifier-side system (200), a holder-side system (300), an issuer-side system (400), and a device (500).

[0042] First, the communication network (100) according to one embodiment of the present invention can be configured regardless of the communication mode such as wired communication or wireless communication, and can be configured with various communication networks such as a local area network (LAN), a metropolitan area network (MAN), and a wide area network (WAN). Preferably, the communication network (100) referred to herein may be the well-known Internet or the World Wide Web (WWW). However, the communication network (100) is not necessarily limited thereto, and may include at least a portion of a well-known wired or wireless data communication network, a well-known telephone network, or a well-known wired or wireless television communication network.

[0043] For example, the communication network (100) may be a wireless data communication network that implements conventional communication methods such as WiFi communication, WiFi-Direct communication, Long Term Evolution (LTE) communication, 5G communication, Bluetooth communication (including Bluetooth Low Energy (BLE) communication), infrared communication, ultrasonic communication, etc., at least in part. As another example, the communication network (100) may be an optical communication network that implements conventional communication methods such as LiFi (Light Fidelity), etc., at least in part.

[0044] Next, a node (not shown) according to one embodiment of the present invention, for example, an issuer node, a holder node, a verifier node, etc., is a contact point or connection point that can communicate with other nodes through a communication network (100), and may be a concept including a physical node such as a server, a computer, a laptop, a smart phone, a tablet PC, etc. (i.e., a digital device equipped with a memory means and equipped with a microprocessor to have computational capabilities), or a logical node such as an application, a program module, a virtual machine, etc. (i.e., a virtual node).

[0045] Specifically, according to one embodiment of the present invention, a node may be a digital wallet in itself, or may be a concept that includes a digital wallet. A digital wallet is a software or hardware device that allows users to securely store and manage digital assets, authentication information, identity information, etc., and refers to a means of storing various data while allowing the stored data to be used as needed. For example, an issuer node, a holder node, and a verifier node may refer to digital wallets owned by an issuer, holder, and verifier, respectively, or digital wallets running on the devices of an issuer, holder, and verifier.

[0046] According to one embodiment of the present invention, these nodes may refer to each node that is interconnected to form a distributed ledger network. According to one embodiment of the present invention, these nodes may include a verifier system (200), a holder system (300), and / or an issuer system (400), which will be described later, in the form of program modules such as applications and widgets to support the use of credentials based on distributed ledger technology (DLT). Furthermore, such program modules may be downloaded from an external application distribution server (not shown) or an external system (not shown).

[0047] Here, according to one embodiment of the present invention, a distributed ledger may refer to a method of storing and managing data distributedly across multiple nodes without centralized authority, while maintaining data integrity and security. Specifically, the distributed ledger described above includes, but is not limited to, blockchain, tangle, hashgraph, and directed acyclic graph (DAG).

[0048] Specifically, the distributed ledger according to one embodiment of the present invention may be a blockchain (or blockchain network). The blockchain network described above may be a network in which multiple nodes participating in the network jointly verify information to be stored on the network, and the verified information is recorded and shared on the network, thereby ensuring the integrity and reliability of the recorded information without relying on an authorized third party. For example, according to one embodiment of the present invention, such a blockchain network may be a network that has at least some characteristics similar to those of conventional blockchain networks such as Bitcoin, Ethereum, and Quantum. Furthermore, according to one embodiment of the present invention, such a blockchain network may be a concept that includes various types of blockchain networks, such as a private blockchain network, a public blockchain network, or a hybrid network of private and public blockchains.

[0049] Meanwhile, according to one embodiment of the present invention, the nodes described above may be interconnected to form a distributed ledger network. This is merely an example and is not intended to be limiting. In other words, a node according to one embodiment of the present invention may refer to any type of reliable storage medium that serves as a participant in verifying and storing data and exchanging information with other nodes to maintain the integrity and consistency of the entire system.

[0050] Next, the verifier system (200) according to one embodiment of the present invention can perform a function of verifying the credential based on information regarding the credential provided from the holder node.

[0051] According to one embodiment of the present invention, the verifier side system (200) may mean a system including a verifier node or included in a verifier node, or may mean the verifier node itself.

[0052] Next, the holder-side system (300) according to one embodiment of the present invention can perform a function of obtaining the provision target and provision range of information generated as a user uses the first VC, providing the generated information to the provision target based on the provision range, and providing a reward to the user in response to the provision of the generated information to the provision target.

[0053] According to one embodiment of the present invention, the holder-side system (300) may mean a system including a holder node or included in a holder node, or may mean the holder node itself.

[0054] The configuration and function of the holder-side system (300) according to the present invention will be described in detail below.

[0055] Next, the issuer system (400) according to one embodiment of the present invention can perform the function of generating a credential and issuing it to a holder node. Typically, an issuer is a trusted institution or organization with the authority to verify information about an individual or organization and issue a credential that verifies such information. Examples of such issuers include, but are not limited to, various institutions such as universities, government agencies, financial institutions, and employers.

[0056] According to one embodiment of the present invention, the issuer-side system (400) may mean a system including an issuer node or included in an issuer node, or may mean the issuer node itself.

[0057] Next, a device (500) according to one embodiment of the present invention is a digital device that includes a function to connect to and communicate with a verifier-side system (200), a holder-side system (300), and / or an issuer-side system (400), and any digital device that has a memory means, a microprocessor, and a computing capability, such as a smart phone, a tablet, a smart watch, a smart band, smart glasses, a desktop computer, a notebook computer, a workstation, a PDA, a web pad, a mobile phone, etc., can be adopted as the device (500) according to the present invention.

[0058] In particular, the device (500) may include an application (not shown) that supports a user to receive a service according to the present invention from a verifier-side system (200), a holder-side system (300), and / or an issuer-side system (400). Such an application may be downloaded from the verifier-side system (200), the holder-side system (300), the issuer-side system (400), and / or an external application distribution server (not shown). Meanwhile, the nature of such an application may be generally similar to the VC management unit (310), information provision unit (320), reward management unit (330), communication unit (340), and control unit (350) of the holder-side system (300), which will be described later. Here, at least a part of the application may be replaced with a hardware device or firmware device that can perform functions substantially the same as or equivalent to it, as necessary.

[0059] According to one embodiment of the present invention, such a device (500) may mean one of a plurality of nodes (e.g., issuer node, holder node, verifier node, etc.) that are interconnected to form a distributed ledger network.

[0060] Configuration of the holder-side system

[0061] FIG. 2 is a drawing showing in detail the internal configuration of a holder-side system (300) according to one embodiment of the present invention.

[0062] As illustrated in FIG. 2, a holder-side system (300) according to one embodiment of the present invention may be configured to include a VC management unit (310), an information provision unit (320), a reward management unit (330), a communication unit (340), and a control unit (350). According to one embodiment of the present invention, at least some of the VC management unit (310), the information provision unit (320), the reward management unit (330), the communication unit (340), and the control unit (350) may be program modules that communicate with an external system (not shown). These program modules may be included in the holder-side system (300) in the form of an operating system, an application program module, or other program modules, and may be physically stored in various known memory devices. In addition, these program modules may also be stored in a remote memory device that can communicate with the holder-side system (300). Meanwhile, these program modules include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc. that perform specific tasks or execute specific abstract data types, as described below, according to the present invention.

[0063] Meanwhile, although the holder-side system (300) has been described as above, this description is exemplary, and it is obvious to those skilled in the art that at least some of the components or functions of the holder-side system (300) may be realized within a device (500) or a server (not shown) or included within an external system (not shown) as needed.

[0064] First, the VC management unit (310) according to one embodiment of the present invention can perform a function of acquiring the provision target and provision scope of information generated as a user uses the first VC.

[0065] Specifically, according to one embodiment of the present invention, a user can use a first VC (Verifiable Credential) held by the user using a digital wallet or the like that operates on a blockchain. According to one embodiment of the present invention, using a VC may mean that a holder node processes information contained in the VC into a Verifiable Presentation (VP) format and presents it to a verifier node. In this context, the user may refer to a holder node, but as will be described later, the user may also act as an issuer node or a verifier node, as needed.

[0066] Continuing, according to one embodiment of the present invention, information may be generated as a user uses the first VC. For example, information presented to the verifier node in a VP for the first VC, a behavioral pattern of the user using the first VC, a purpose for which the user uses the first VC, information received from the verifier node and / or the issuer node in response to the user's use of the first VC, etc. may be included in the information generated as the user uses the first VC. Here, according to one embodiment of the present invention, the verifier node and the issuer node may refer to the same entity in some cases. For example, when a user (holder node) presents a VP for the first VC to a specific entity, the specific entity may be referred to as a verifier node because it performs the role of a verifier node. However, if the specific entity issues a VC to the user after successfully completing verification, the specific entity may be referred to as an issuer node because it performs the role of an issuer node.

[0067] According to one embodiment of the present invention, information generated when a user uses the first VC may be de-identified. According to one embodiment of the present invention, de-identification may include, but is not limited to, removing the user's personally identifiable information, categorizing indirectly identifiable information (e.g., categorizing actual age into age groups (e.g., 20s, 30s), or categorizing detailed addresses into regions (e.g., Incheon City, Gyeonggi Province), etc.), and the like. Various modifications may be made within the scope of achieving the purpose of the present invention.

[0068] The VC management unit (310) according to one embodiment of the present invention may use technologies or algorithms such as differential privacy technology, K-anonymity guarantee algorithm, data masking, and data generalization for such anonymization processing, but is not limited thereto and may be variously changed within the scope of achieving the purpose of the present invention.

[0069] Furthermore, this de-identification process may be performed after information is generated as the user uses the first VC, or may be performed before or during the user's use of the first VC. That is, according to one embodiment of the present invention, the de-identification process may be performed before information generated as the user uses the first VC is provided to the target of provision.

[0070] Additionally, according to one embodiment of the present invention, the de-identification process may be performed according to the category to which the information generated when the user uses the first VC belongs.

[0071] Specifically, the VC management unit (310) according to one embodiment of the present invention can determine a category (e.g., usage records related to medical data, usage records related to financial data, etc.) to which information generated as a result of the user using the first VC belongs based on the purpose for which the user uses the first VC, and for this purpose, can analyze the behavioral pattern of the user using the first VC using a pre-learned artificial intelligence model. In addition, the VC management unit (310) according to one embodiment of the present invention can de-identify the information generated as the user uses the first VC to suit the category to which the information belongs.

[0072] For example, assuming that the information generated by a user's use of the first VC corresponds to a usage record regarding medical data, processing can be performed, such as removing personally identifiable information, categorizing actual age into age groups, zoning detailed addresses, and processing disease information.

[0073] Meanwhile, according to one embodiment of the present invention, the first VC is a term used to refer to at least one VC held by a user, and it should be understood that in some cases, the first VC may also refer to two or more VCs held by the user. Accordingly, according to one embodiment of the present invention, information generated when a user uses two or more VCs may also be included in the information generated when the user uses the first VC.

[0074] Continuing, the VC management unit (310) according to one embodiment of the present invention can obtain the provision target and provision scope of the information generated as described above. According to one embodiment of the present invention, the provision target may refer to an entity (e.g., an insurance company, a securities company, etc.) receiving the information, and the provision scope may refer to the information items (e.g., age (or age group), address (or region), disease code, prescription record, etc.) provided to the provision target among the information generated as described above, the degree of anonymization processing, etc.

[0075] The VC management unit (310) according to one embodiment of the present invention may provide a user interface that enables the user to set the provision target and provision scope through a digital wallet in order to obtain the provision target and provision scope.

[0076] For example, the VC management unit (310) according to one embodiment of the present invention may provide the user with information about what reward (a detailed description of which will be described later) can be received by providing what information (i.e., scope of provision) to what target (i.e., target of provision) through a digital wallet.

[0077] More specifically, for example, the VC management unit (310) according to one embodiment of the present invention can provide the user with information through the digital wallet that an insurance premium discount coupon can be received by providing the insurance company with information such as age group, region, disease code, prescription record, etc. (such information itself may be obtained from another platform linked to the digital wallet), and can obtain the provision target and provision scope by allowing the user to determine the provision target and provision scope of information generated by using the first VC based on such information.

[0078] Meanwhile, according to one embodiment of the present invention, the scope of provision of information generated when a user uses the first VC may be determined simply by the user agreeing to the provision of de-identified personal information, and the target of provision may be automatically determined by the user determining the scope of provision of information (i.e., the user may not explicitly specify the target of provision).

[0079] Next, the information provision unit (320) according to one embodiment of the present invention can perform a function of providing the corresponding information to the provision target based on the provision range of information generated as the user uses the first VC.

[0080] Specifically, the VC management unit (310) according to one embodiment of the present invention may provide a user interface that allows the user to consent to providing information generated by the user's use of a first VC to a target of provision based on the scope of provision via a digital wallet. If the user consents to the provision of the information, the VC management unit (310) according to one embodiment of the present invention may issue a second VC to the target of provision, proving that the user consents to the provision of the information. In this context, the user may refer to the issuer node. Here, according to one embodiment of the present invention, the second VC thus issued may be signed with the private key of the user (or the digital wallet used by the user).

[0081] Continuing, the information providing unit (320) according to one embodiment of the present invention may provide the information to the provision target based on the second VC used (or presented) by the user (or the digital wallet used by the user) to obtain information generated by the user's use of the first VC, or the second VC issued by the user to the provision target. For example, the information providing unit (320) according to one embodiment of the present invention may determine whether the second VC used by the provision target is valid, and may provide the information to the provision target in response to determining that the second VC is valid. In this context, the user may refer to a verifier node.

[0082] According to one embodiment of the present invention, the second VC issued to the provision target by the VC management unit (310) as described above may be revoked by the user. For example, in a situation where information generated by the user's use of the first VC must be provided to the provision target at regular intervals, the provision target may use (or present) the second VC to the user (or the digital wallet used by the user) at each interval to verify its validity before receiving the relevant information, thereby avoiding the inconvenience of having to separately obtain the user's consent at each interval. In addition, by allowing the user to revoke the second VC when they no longer wish to provide information, the user can conveniently and clearly refuse to provide information.

[0083] Next, the compensation management unit (330) according to one embodiment of the present invention can perform a function of providing compensation to the user in response to the information generated as the user uses the first VC being provided to the provision target.

[0084] Specifically, the compensation management unit (330) according to one embodiment of the present invention can enable the compensation to be paid to the user based on the third VC issued to the user by the provision target in relation to the payment of compensation according to the user's provision of information.

[0085] For example, the provision target may issue a third VC to the user in response to the user's consent to the provision of information generated by the user's use of the first VC (e.g., issuing the second VC to the provision target proving consent as described above), and the reward management unit (330) according to one embodiment of the present invention may enable the user to receive a reward by proving to the provision target that the user possesses the third VC. According to one embodiment of the present invention, the reward may be in the form of a token or point, but is not limited thereto.

[0086] As another example, in response to a user's consent to the provision of information generated by the user's use of the first VC (e.g., issuing a second VC to the provider proving consent as described above), the third VC itself issued by the provider to the user may represent a reward received by the user.

[0087] According to one embodiment of the present invention, the reward paid to the user may be determined based on the value of the information provided to the recipient. For example, the greater the amount of information provided to the recipient, the greater the value of that information may be judged. The broader the scope of information provided to the recipient, the greater the value. The value may also vary depending on the type of information provided to the recipient. According to one embodiment of the present invention, an interface may be provided to the user and / or the recipient, if necessary, to monitor the status of information provision in real time.

[0088] According to one embodiment of the present invention, the process of providing a reward to a user (e.g., evaluating the value of information provided to a service provider and determining a reward to be provided to the user based on the evaluation result) and recording the result can be automatically performed based on a smart contract, thereby enabling transparent management of the reward history.

[0089] Meanwhile, the reward management unit (330) according to one embodiment of the present invention may provide an event to a user based on information provided to the provision target, and may provide an additional reward to the user in response to the user's participation in the event.

[0090] For example, the reward management unit (330) according to one embodiment of the present invention may provide the user with an event determined based on information provided to the provision target, such as a survey on a specific topic related to the user. According to one embodiment of the present invention, such an event may be determined by the provision target according to the provision target's target marketing policy. In addition, the reward management unit (330) according to one embodiment of the present invention may provide an additional reward to the user in return for participating in the event (e.g., responding to a survey).

[0091] Next, the communication unit (340) according to one embodiment of the present invention can perform a function that enables data transmission and reception from / to the VC management unit (310), information provision unit (320), and compensation management unit (330).

[0092] Finally, the control unit (350) according to one embodiment of the present invention can perform a function of controlling the flow of data between the VC management unit (310), the information provision unit (320), the compensation management unit (330), and the communication unit (340). That is, the control unit (350) according to one embodiment of the present invention can control the flow of data from / to the outside of the holder-side system (300) or the flow of data between each component of the holder-side system (300), thereby controlling the VC management unit (310), the information provision unit (320), the compensation management unit (330), and the communication unit (340) to perform their own functions.

[0093] The embodiments of the present invention described above may be implemented in the form of program commands that can be executed by various computer components and recorded on a computer-readable recording medium. The computer-readable recording medium may include program commands, data files, data structures, etc., either singly or in combination. The program commands recorded on the computer-readable recording medium may be specially designed and configured for the present invention or may be known and available to those skilled in the art of computer software. 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 commands, such as ROMs, RAMs, and flash memories. Examples of program commands include not only machine language codes generated by a compiler, but also high-level language codes that can be executed by a computer using an interpreter, etc. Hardware devices may be changed into one or more software modules to perform processing according to the present invention, and vice versa.
