摘要
The present invention can provide a user authentication method and system for more securely performing user authentication by registering a user ID and a user public key in a programmable blockchain and performing a user authentication program. In addition, by accessing the blockchain through the authentication server (or management server), multiple service provider servers can check the user information without having to individually create a blockchain transaction. In addition, by encrypting the user information verified through the certification authority and stored in the blockchain, there is no need to verify the user's identity every time the user is authenticated, and there is no risk of leakage of user information even if the service provider server is hacked. In addition, the use of a programmable blockchain, for example, Ethereum, ensures the integrity of user authentication programs as well as user information, and even an authentication server cannot tamper with the user authentication program of the blockchain. In addition, since a single ID can log in to multiple institution servers, provide user information, and authenticate user information, user information is not distributed to multiple institution servers, making it easy to manage user information. When changing user information such as information, server information, phone number or personal documents, or whenever a service provider subscribes to a service, both ID and password are memorized, and there is no inconvenience of having to re-enter user information.
