As the use of biometrics becomes more wide-spread, the privacy concerns thatstem from the use of biometrics are becoming more apparent. As the usage ofmobile devices grows, so does the desire to implement biometric identificationinto such devices. A large majority of mobile devices being used are mobilephones. While work is being done to implement different types of biometricsinto mobile phones, such as photo based biometrics, voice is a more naturalchoice. The idea of voice as a biometric identifier has been around a longtime. One of the major concerns with using voice as an identifier is theinstability of voice. We have developed a protocol that addresses thoseinstabilities and preserves privacy. This paper describes a novel protocol thatallows a user to authenticate using voice on a mobile/remote device withoutcompromising their privacy. We first discuss the \vv protocol, which hasrecently been introduced in research literature, and then describe itslimitations. We then introduce a novel adaptation and extension of the vaultedverification protocol to voice, dubbed $V^3$. Following that we show aperformance evaluation and then conclude with a discussion of security andfuture work.
