Then, entering a step S502, wherein the trusted identity authentication platform verifies the basic identity information of the user, generates credential declaration body information containing a hash abstract of the basic identity information, the first identification information, at least one second identification information and an authentication serial number after the verification is passed, and signs the credential declaration body information to obtain the identity authentication result credential containing the signature; carrying out hash calculation on the identity authentication result certificate to obtain a certificate storage hash abstract, uploading the certificate storage hash abstract to the blockchain through the trusted identity authentication node, and sharing the certificate storage hash abstract to at least one service node through the blockchain;
Then, step S503 is entered, the first service system receives the identity authentication result certificate and the authentication serial number sent by the trusted identity authentication platform, and shares the identity authentication result certificate and the authentication serial number to the second service system;
and then, the step S504 is carried out, the second service system obtains the certificate storage hash abstract from the service node according to the authentication serial number, and verifies the identity authentication result certificate according to the certificate storage hash abstract.
In this embodiment, the first service system is an initiator of identity authentication, and the second service system is a sharing party of identity authentication, that is, after a user only needs to input basic identity information in the first service system, the second service system does not need to collect the basic identity information of the user through the method disclosed by the application, and by receiving the identity authentication result certificate sent by the first service system and acquiring the certificate storage hash digest from the corresponding blockchain service node, the identity authentication operation required during handling the related flow of the second service system can be completed, thereby realizing the transmission of the identity authentication result in a plurality of service systems and effectively improving the identity authentication efficiency.
In this embodiment, the first identification information is unique identification information corresponding to the first service system, the second identification information is unique identification information corresponding to the second service system, and the first identification information and/or the second identification information may be letters, numbers, character strings, two-dimensional codes, and the like.
