PURPOSE: An authentication system using sound bar codes is provided to authenticate a speaker with stable authentication rate using a sound generator in which a sound bar code provided with a unique sound pattern is recorded. CONSTITUTION: An authentication system using sound bar codes includes a sound bar code recognition system(100). The sound bar code recognition system is composed of a recorder(110) for recording the voice of a user, a voice database(130) for storing the voice of the user, a sound bar code solution(140) for controlling a sound bar code encoder(102), a bar code database(150) for recording and managing sound bar codes, an interface(160) for inputting and outputting the sound bar codes, and a sound bar code recognition module(170) for recognizing a sound bar code to judge if a speaker is authenticated or not. The authentication system records the sound bar code in a sound generator(201) with a sound bar code recorder(200) and sets the sound generator in a target hardware(202) to generate the sound bar code as a sound. |
