摘要
PURPOSE: A user authentication method based on OTP(One Time Password) is provided to solve a user authentication weakness problem by reinforcing security in an electronic finance service.;CONSTITUTION: A server(200) transmits a random number challenge value to a user(S22,S24). The user transmits voice data to a server by enabling a user to input the voice data through a microphone module mounted in a smart phone(100)(S26). The server authenticates a client terminal by using information received from a user and transmits an authentication result to the user by using a random value(S28). The user generates voice OTP by using a challenge value received from the server and the voice data(S30). The user is finally authenticated by transmitting the voice OTP to the server(S32).;COPYRIGHT KIPO 2013
