In the marital registration process, identity information of a registrant needs to be verified, namely, a business scene needs to ensure that the registrant and an identity card held by the registrant are the same.
The user side executes S100: sending a marital registration request to a cross-link node 1, wherein the service request comprises an identity authentication request and a registration request, the identity authentication request is a cross-link service request, and the type of the identity authentication request is identity authentication, wherein the identity authentication request comprises an identity card number of a registrant, fingerprint data or face data; the registration request is a local service request for recording the identity information of both couples registering the marriage on the marriage registration chain.
After receiving the marriage registration request sent by the user side, the cross-link node 1 executes S200: analyzing the service request, and analyzing that the service request includes an authentication request, and the type of the authentication request is authentication, that is, according to a routing rule pre-configured when forming the P2P network, the cross-link node 2 performs S300: cross-link node 2 is accessed.
After the cross-link node 1 accesses the cross-link node 2, calling a client deployed by the cross-link service 2 to access an identity verification chain; in fact, the client that invokes the cross-chain service 2 deployment is a certain node in the access authentication chain, and is executed by the node S500: and verifying whether the identity of the registrant is real, namely judging whether the identity card number provided by the registrant is matched with the fingerprint or the face provided by the registrant, if so, determining that the verification result is real, otherwise, determining that the verification result is not real. In this embodiment, the identity verification chain is written into the identity data of the citizen by the public security system, and includes information such as an identity card number, a fingerprint or a face.
Returning the verification result by the node on the authentication chain to the cross-chain node 2, completing S600, and then executing S600a by the cross-chain node 2: and sending the verification result back to the interlinkage point 1, judging whether the registration request is responded or not by the interlinkage node 1 according to the verification result feedback, namely recording the identity information of the couples and the couples registering the marriage on the marital registration chain if the verification result is true, and sending the marital registration request back to the user end by the interlinkage node 1 after successful chaining, namely prompting the successful marital registration. In this embodiment, the marital registration chain is written with the marital data of the citizen by the civil bureau system, and at the same time, the writing of a new block on the marital registration chain is synchronized to the civil bureau system.
