Abstract:
A method for secure transmission of user-authenticating information is provided. The method includes steps of: a service-providing server (a) determining whether a public key of the user is registered in a blockchain network, and instructing a user-authenticating information generator to generate user-authenticating information for reference, instructing an encrypting engine to encrypt the generated user-authenticating information for reference by using the public key of the user retrieved from the blockchain network, and instructing a message-sending part to transmit the encrypted user-authenticating information for reference to a mobile device of the user; and (b) in case that user-authenticating information for comparison is acquired from the user device and if the user-authenticating information for comparison is determined as identical to the user-authenticating information for reference, providing the user device with the service desired by the user.

Claim (Index 9):
A service-providing server for secure transmission of user-authenticating information, comprising:\n at least one memory that stores instructions; and at least one processor configured to execute the instructions to perform processes of: (I) if a service request for a service desired by a user is acquired from a user device, determining whether a public key of the user is registered in a blockchain network or supporting another device connected with the service-providing server to determine whether the public key of the user is registered in the blockchain network, and if the public key of the user is determined as registered in the blockchain network, instructing a user-authenticating information generator to generate user-authenticating information for reference, instructing an encrypting engine to encrypt the generated user-authenticating information for reference by using the public key of the user retrieved from the blockchain network, and instructing a message-sending part to transmit the encrypted user-authenticating information for reference to a mobile device of the user or supporting another device connected with the service-providing server to transmit the encrypted user-authenticating information for reference to the mobile device of the user, and (II) in case that user-authenticating information for comparison is acquired from the user device, wherein the mobile device instructs a decrypting engine to decrypt the encrypted user-authenticating information for reference received from the service-providing server into decrypted information by using a private key of the user which has been stored beforehand, and displays the decrypted information, and then the user-authenticating information for comparison is inputted by the user via the user device after the user confirms the decrypted information displayed on the mobile device, and if the user-authenticating information for comparison is determined as identical to the user-authenticating information for reference, providing the user device with the service desired by the user who has sent the service request or supporting another device connected with the service-providing server to provide the user device with the service desired by the user who has sent the service request.
