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: A method and an apparatus for fingerprint recognition are disclosed. The apparatus for the fingerprint recognition may extract a plurality of fingerprint feature points from a fingerprint image and may predetermine a group among the plurality of fingerprint feature points. The apparatus for the fingerprint recognition may also calculate a ridge number between the first fingerprint feature points included in the group and may use the ridge number to generate a ridge count sequence.

Abstract: Provided are management and use of an authentication medium, and specifically, to an apparatus and method for registering and using an IC card as an authentication medium in a user terminal. An apparatus for using the IC card as the authentication medium includes an ID extracting module configured to extract identification information from the IC card that performs near field communication with a user terminal; an ID checking module configured to determine whether the extracted identification information matches identification information of the IC card that is previously registered as an authentication medium; and a security service module configured to provide a security service interface for a security service provided by the determined IC card.
