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

这个小型企业技术转移第一阶段的研究项目是开发指纹系统的活性确认，以减少对欺骗的脆弱性。生物识别系统，通过指纹等生理特征进行身份验证，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”并被复制以实现身份验证，称为欺骗。该项目将开发一种通过纯软件方法检测活性的方法，该方法可以与任何主流商业指纹技术相集成。这种方法考虑了由现有扫描仪直接测量的一幅或多幅图像中的水分变化。预计活跃性是安全方面的一项关键技术，通过将其脆弱性降至最低并通过增加用户对该技术的信心来使生物识别系统变得成熟。这项研究将减少生物识别的脆弱性，并扩展到其他新兴的生物识别研究领域。通过开发活跃性，生物识别系统的主要漏洞之一将被降至最低，从而使这项技术能够实现其承诺，增加对日益电子化和远程的交易的信任。有必要以更可靠的方式将电子身份与个人联系起来。生物识别认证正在发展壮大的行业，其应用包括通过新的生物识别识别卡为政府雇员识别身份，用于边境安全的电子护照(EPassport)，以及电子支付系统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.
