The value and importance of personal information are increasing due to the increasing number of fields where the Internet environment and computing environment are used, and user authentication technology is also changing. Until now, accredited certificates, which are mainly used in the financial sector, are being replaced with biometric authentication technology due to the problem of revocation. However, another problem is that biometric information cannot be modified once it is leaked. Recently, with the advent of blockchain technology, research on user authentication methods has actively progressed. In this paper, both public certificate and blockchain-based user authentication can be used without system change, and a new DID issuance and reissuance method that can replace the resident registration number is presented. The proposed system can be used without restrictions in a blockchain. However, the currently used DID requires installation of an application at the Interworking Support Center for verification. Since a DID can be authenticated without registering as a member, indiscriminate information collection can be prevented. Security, convenience, and determinism are compared with the existing system, and excellence is proven based on various attack methods, its portability, and proxy use.
