STTR Phase II: Dynamic Passphrase Voice Security System

这项小型企业技术转移（STTR）第二期项目的重点是研究和开发一种新型的语音认证安全系统，该系统结合了语音验证和说话人验证。作为认证的基础，所提出的系统生成一个一次性的密码短语，用户被要求立即响应。在质询之后，双重验证引擎验证响应是所需的密码短语并且其与阐明密码短语的人相关联。所提出的系统解决了以前的语音认证系统与“耳拍”冲浪，窃听和盗窃相关联的漏洞。该提案为身份盗窃威胁提供了解决方案，其中个人信息不能大声说出，并进一步解决了密码系统的限制。拟议的项目将开发和建造一个系统，扩大语音能力，包括更广泛的用户、渠道和语音类型选择。该系统将扩展密码短语生成，以支持大客户及其密码短语“主题选择”隐私功能。此外，该系统将自动登记用户在多个呼叫克服以前的限制，由于不足的语音跨渠道。拟议项目的成果包括通过语音识别应用程序、语音通道和融合平台数量的广泛增长，通过语音进行安全认证。随着越来越多的人在各种设备和网络（如VoIP或蜂窝）上使用他们的语音，实时语音应用将受益于所提出的方法。所提出的语音安全系统方法也可以是那些具有视觉或其他适用障碍的人的选择。由于安全漏洞和相关身份盗窃的不断增加，该项目的成果将通过为支持语音的用户界面提供强大的安全选项来显著影响社会。

This Small Business Technology Transfer (STTR) Phase II project focuses on the research and development of a novel voice authentication security system which combines speech verification with speaker verification. As a basis for authentication, the proposed system generates a one-time pass-phrase which users are challenged to respond to immediately. Following the challenge, the dual verification engine verifies that the response is the required pass-phrase and that it is associated with the person articulating the pass-phrase. The proposed system addresses the vulnerabilities of previous voice authentication systems associated with 'ear shot' surfing, eavesdropping and theft. The proposal offers a solution for identity theft threats where personal information cannot be said aloud and further addresses password systems limitations. The proposed project will develop and construct a system which expands the voice capabilities to include a wider selection of users, channels and types of speech. The system will expand pass-phrase generation to support large customers and its passphrase 'topic selection' privacy feature. Additionally, the system will automatically enroll users over multiple calls overcoming previous limitations due to inadequate speech across channels. The outcomes of the proposed project include secure authentication through speech via the widely growing number of speech recognition applications, voice channels and converged platforms. As more individuals use their voice on a variety of devices and networks such as VoIP or cellular, real-time, speech applications will benefit from the proposed method. The proposed speech security system method may also be the choice for those with visual or other applicable handicaps. Because of the continuous rise of security breaches and related identity theft, the outcomes of this project should significantly impact society by providing a robust security option for speech-enabled user interfaces.
