SYSTEM AND METHODS FOR PERSONAL IDENTIFICATION NUMBER AUTHENTICATION AND VERIFICATION USING A NON-DISCLOSING PASSWORD SCHEME FOR TRANSMISSION OF THE PIN OVER A NON-SECURE ACOUSTIC CHANNEL USING VOICE RECOGNITION
Systems and methods to authenticate and verify user access replace the digits of a personal identification number (PIN) of a particular user with prompted randomized words that are to be uttered by an unidentified user. By virtue of this replacement, the PIN remains secret. A known speaker provides voice samples to the system in advance. The words uttered by the unidentified user (in response to the prompted words being displayed) correspond to digits. The uttered words are checked against the PIN, and are used to verify if the unidentified user's voice matches the voice of the known speaker.
