摘要
An OTP(One Time Password) security authentication system and an authentication method using a voice signal are provided to prevent a piracy on a user terminal by generating the voice signal without directly pressing numbers. A start button starts a generation of an OTP. A client side OTP generator(101) generates an OTP of a terminal by using an event counter and time information of a terminal. A client side encoder(101a) encodes the OTP. A client side terminal(100) includes an OTP/voice converter for converting the encoded OTP into a voice signal. An OTP authentication server receives the data from a terminal and includes an OTP comparator, which determines whether the data is matched with a specific OTP.
