METHOD FOR AUTHENTICATING USER USING VOICE RECOGNITION, DEVICE AND SYSTEM FOR THE SAME

摘要

PURPOSE: A user authentication method using voice recognition, an apparatus for the same, and a system are provided to record a noise signal in user voice by mixing the noise signal in the user voice in case of user authentication or call when an opponent or a third person illegally records the user voice. CONSTITUTION: A computation unit (300) authenticates a user by comparing a voice signal which is inputted for voice authentication with voice information of a real user. A noise output unit (500) mixes a noise signal in the inputted voice signal. A noise elimination unit (700) mixes a negative noise signal for the noise signal in the mixed voice signal. The noise elimination unit provides the voice signal in which the negative noise signal is mixed to the computation unit.
