Abstract: There is disclosed an n-dimensional biometric security system as well as a method of identifying and validating a user through the use of a automated random one-time passphrase generation. The use of tailored templates to generate one-time phase phrase text as well as the use of update subscriptions of templates ensures a high level of security. A verification session preferably uses short, text-independent one-time pass phrases and secure audio tokens with master audio generated from an internal text-to-speech security processor. An automated enrollment process may be implemented in an ongoing and seamless fashion with a user's interactions with the system. Various calibration and tuning techniques are also disclosed.

Abstract: A security system and method are provided that relies, in one embodiment, on speech recognition to not only identify but also to validate a user. In use, the system requires a user to initially input information representative of the user at a station. A responsive signal is then generated and validated as representative of the user. Thereafter, a randomly generated challenge phrase appears at the station for the user to speak in response to validation of generated signal. The user then speaks the randomly generated challenge phrase and generates a second signal representative of the spoken response to the challenge phrase. This second signal is then processed for determining what was actually spoken as well as for the voice characteristics of the speaking voice. If a match is made for the two parameters, identification and validation of the user is complete and access is given.
