Abstract
A method for providing an authentication service by using a decentralized identity (DID) application of a first user device, a mobile device, is provided. The method includes steps of: (a) if a signature verification value is transmitted from a service provider server in response to a DID service requested by a second user device, a DID authentication server transmitting the signature verification value to the DID application so that the DID application transmits a user signature and a user DID to the DID authentication server, and (b) verifying the user signature by using a user public key and transmitting signature verification result information to the service provider server, or transmitting the user signature and the user DID to the service provider server, to allow the service provider server to verify the user signature by using the user public key, to thereby provide the DID service to the second user device.
