随着生物识别技术的应用越来越广泛，源于生物识别技术使用的隐私问题也变得越来越明显。随着移动设备使用的增长，在这些设备中实现生物识别的愿望也在增长。绝大多数正在使用的移动设备是移动电话。虽然人们正在努力将不同类型的生物识别技术应用于手机，比如基于照片的生物识别技术，但语音识别是一个更自然的选择。声音作为生物识别的想法已经存在很长时间了。使用语音作为标识符的主要问题之一是语音的不稳定性。我们已经开发了一个协议来解决这些不稳定性并保护隐私。本文描述了一种允许用户在移动/远程设备上使用语音进行身份验证而不损害其隐私的新协议。我们首先讨论了最近在研究文献中介绍的拱形验证协议，然后描述了它的局限性。然后，我们介绍了一种新的适应和扩展的拱形验证协议的语音，称为拱形语音验证（V3）。接下来，我们展示一个性能评估，然后以安全性和未来工作的讨论结束。
As the use of biometrics becomes more wide-spread, the privacy concerns that stem from the use of biometrics are becoming more apparent. As the usage of mobile devices grows, so does the desire to implement biometric identification into such devices. A large majority of mobile devices being used are mobile phones. While work is being done to implement different types of biometrics into mobile phones, such as photo based biometrics, voice is a more natural choice. The idea of voice as a biometric identifier has been around a long time. One of the major concerns with using voice as an identifier is the instability of voice. We have developed a protocol that addresses those instabilities and preserves privacy. This paper describes a novel protocol that allows a user to authenticate using voice on a mobile/remote device without compromising their privacy. We first discuss the Vaulted Verification protocol, which has recently been introduced in research literature, and then describe its limitations. We then introduce a novel adaptation and extension of the Vaulted Verification protocol to voice, dubbed Vaulted Voice Verification (V3). Following that we show a performance evaluation and then conclude with a discussion of security and future work.
