Referring to FIG. 5 , the DID verification process may include registering the DID of the certificate issuer and the DID of the certificate requester in the block chain ( S51 and S52 ). DID is decentralized identification information that can be managed on a blockchain. The certificate requester who has registered the DID may request a claim for identity information from the certificate issuer who has registered the DID ( S53 ). Requesting a claim for identity information may correspond to a request for authentication of identity information, such as a resident registration number, gender, etc. by a requestor for certification. The certificate issuer who has been requested to claim the identity information may issue a verifiable claim by authenticating the identity information of the certificate requester ( S54 ). A verifiable identity unit may be issued in the form of a certificate. The proof requester may submit the identity unit issued to the proof verifier (S55). The proof verifier may correspond to a service provider, etc. for which the proof requester intends to use the service by proving his/her identity. The proof verifier may verify the identity unit of the proof requester through the block chain (S56), and if the identity is verified, the access of the proof requester may be allowed (S57). For example, if the proof verifier is a service provider and the proof requester requests proof of identity to use the service provider's service, the service provider can verify the identity of the proof requester in the blockchain and allow access to the service. .

The DID authentication method corresponds to a self-sovereign identity model in which the identity subject requests the issuer to issue a certificate related to personal information and delivers the issued certificate to the verifier. There are features that enable secure identity management.

The multi-type membership integrated management system according to an embodiment can use a method in which each membership issuer proves the identity of each user through the DID authentication method, and the membership issuer's authentication information for the user is combined with the integrated membership usage history in a block chain can be stored in

In addition, as will be described in detail below, the DID authentication method may be used in the integrated membership issuance process and the settlement process according to the use of the integrated membership.

A DID proof blockchain network may correspond to a blockchain network that proves identification information such as DID. The DID proof blockchain network may include a blockchain that manages DID, which is identification information, and the membership issuer(s) and management server may participate. Proof requesters and certificate issuers can generate their own identification information, DID, and store it in the DID proof blockchain network. The certificate issuer can verify the identity of the certificate requester by inquiring on the blockchain, and can issue a verifiable identity unit such as a certificate to the verified certificate requester. The identity unit issued by the certificate issuer may include the certificate issuer's signature. The proof verifier can verify the identity of the proof requester by inquiring the identity unit submitted by the proof requester in the DID proof blockchain network, and can allow service access to the proof requester whose identity has been verified. The proof verifier can verify the identity unit by inquiring in the blockchain network the signature of the proof issuer, the proof requester’s DID, and the proof issuer’s DID included in the identity unit.
