STTR Phase I: Software-Based Liveness to Prevent Spoofing Fingerprint Biometric Scanners

这个小型企业技术转移阶段的研究项目是开发指纹系统的活动性确认，以减少对欺骗的脆弱性。通过指纹等生理特征进行身份验证的生物识别系统已被建议在增加便利性的同时提高安全性。一个限制是它可以被“窃取”和复制以实现身份验证，称为欺骗。该项目将开发一种通过软件方法检测活体的方法，该方法可以与任何主流商业指纹技术集成。该方法考虑了现有扫描仪直接测量的一张或多张图像中的水分变化。可以预见，活动性是一项关键的安全技术，通过最大限度地减少生物识别系统的漏洞和增加用户对该技术的信心，使生物识别系统成熟。本研究将有助于降低生物识别的脆弱性，并将其推广到其他新兴的生物识别研究领域。通过开发活动性，生物识别系统的一个主要漏洞将被最小化，从而使该技术能够实现其承诺，即在日益电子化和远程化的交易中增加信任。有必要以更可靠的方式将电子身份与个人联系起来。生物识别认证是一个不断发展的行业，其应用包括通过一种新的具有生物识别功能的身份证对政府雇员进行身份识别，用于边境安全的电子护照（电子护照），以及电子支付系统“触摸支付”（Pay by Touch），以减少身份欺诈。

This Small Business Technology Transfer Phase I research project is the development of liveness confirmation for fingerprint systems to reduce vulnerability to spoofing. Biometrics systems, authentication through physiologic characteristics such as fingerprints, have been suggested to improve security while increasing convenience. One limitation is that it can be 'stolen' and replicated to achieve authentication, termed spoofing. This project will develop a means to detect liveness through a software-only approach which can be integrated with any mainstream commercial fingerprint technology. This approach considers the moisture changes in one or more images directly measured by the existing scanner. It is anticipated that liveness is a critical technology in security to enable the maturity of biometric systems by minimizing its vulnerabilities and by increasing user confidence in the technology. This research will decrease biometric vulnerability and extend to other emerging biometric research areas. By developing liveness, one of the main vulnerabilities of biometric systems will be minimized, thus, enabling the technology to achieve its promise to increase trust in transactions that are increasingly electronic and remote. There is a need to link electronic identity to an individual in more reliable ways. Biometric authentication is growing industry with applications that include identification for government employees through a new biometrically-enabled identification card, electronic passports for border security (ePassport), and electronic payments systems, Pay by Touch, to reduce identity fraud.
