Abstract: Disclosed herein are a terminal apparatus, a server apparatus, and a method for FIDO universal authentication using a blockchain. The method includes sending, by the terminal apparatus, a FIDO service request for any one of FIDO registration, FIDO authentication, and FIDO deregistration for an application service provided by the server apparatus to the server apparatus; verifying, by the blockchain, a FIDO service response message, which is created as a result of local authentication of a user in the terminal apparatus in response to the FIDO service request; and processing, by the server apparatus, the FIDO service request based on whether the FIDO service response message is successfully verified by the blockchain.

Abstract: Disclosed herein are an apparatus and method for providing an anonymous delegated credential in a DID-based service. A method for issuing an anonymous delegated credential in a DID-based service includes receiving an anonymous delegated credential issuance request message from a digital wallet of a delegate, setting attribute values in the anonymous delegated credential, anonymizing delegator identification information and delegatee identification information among the attribute values, and issuing the generated anonymous delegated credential to the digital wallet of the delegatee.

Abstract: Disclosed herein are an apparatus and method for managing a history of object owners. The method includes generating, by an object owner history management apparatus, a product registration Verifiable Credential (VC) in a form of a Merkle tree, and registering the product registration VC in a blockchain in order to manage a history of owners of an object, acquiring, by a first user terminal device, the product registration VC from the blockchain and registering a first owner VC, generated based on the product registration VC, in the blockchain to register an ownership of the object, and acquiring, by a second user terminal device, a product transfer Verifiable Presentation (VP) from the first user terminal device and registering a second owner VC, generated based on the product transfer VP, in the blockchain to receive transfer of the ownership of the object.

Abstract: Disclosed herein are a method and apparatus for converting a credential data schema. The method for converting a credential data schema includes checking credential data in response to a credential data schema conversion request statement received from a requester terminal, and checking a decentralized identifier of a credential issuer based on the credential data, retrieve a decentralized identifier document through a decentralized identifier resolver, verifying a credential to be converted based on the decentralized identifier document, when verification of the credential is completed, generating a credential data schema identifier for the credential, retrieving a credential data conversion schema corresponding to the credential data schema conversion request statement based on the credential data schema identifier, converting the credential data schema based on the credential data conversion schema and generating a credential data schema conversion result, and checking identity information of the credential issuer through an issuer identity information registry.

Abstract: Disclosed herein are an apparatus and method for issuing delegated credentials between digital wallets possessed by multiple users connected to a Decentralized Identifier (DID) registry through wired/wireless communication. The method includes receiving, by a digital wallet of a first user, a delegated credential issuance request message including a newly created DID document from a digital wallet of a second user, generating, by the digital wallet of the first user, a delegated credential using both the delegated credential issuance request message, received from the digital wallet of the second user, and an original credential, previously issued by the digital wallet of the first user, and transmitting, by the digital wallet of the first user, the generated delegated credential and the original credential, together with a delegated credential registration request message, to the digital wallet of the second user.

Abstract: Disclosed herein are an apparatus and method for recommending privacy control. A privacy control server includes multiple common privacy control recommendation models learned based on personal information provision histories of multiple users, a user preference determination unit for generating at least one question item based on the multiple common privacy control recommendation models and determining a privacy control preference of a user based on a result of a user answer to the at least one question item, and a common privacy control recommendation model provision unit for providing a common privacy control recommendation model selected to match the privacy control preference of the user to the user.

Abstract: Disclosed herein are an apparatus and method for managing personal information. The method includes a step in which a user terminal device registers the decentralized identification information of a user in a blockchain, receives the personal information of the user, stores the same in an endpoint for managing the personal information, and registers a personal information access policy for the personal information in a first server; a step in which the apparatus receives the decentralized identifier of the user, retrieves the decentralized identification information of the user, corresponding to the decentralized identifier, from the blockchain, and requests a personal information access token for accessing the personal information from the first server using the decentralized identification information; and a step in which the apparatus identifies the endpoint from the personal information access token, which is generated based on the personal information access policy, and retrieves the personal information from the endpoint.

Abstract: Disclosed herein are an apparatus and method for user authentication based on multiple pieces of biometric information. The apparatus may include one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program receives multiple pieces of biometric information from the client device of a user, generates the personal identifier of the user using a neural network and a Bloom filter algorithm, and checks the similarity between the personal identifier of the user and each of personal identifiers previously registered in a database, thereby authenticating the user.
