We propose the use of correlation mapping optical coherence tomography (cmOCT) to deliver additional biometrics associated with the finger that could complement existing fingerprint technology for law enforcement applications. The current study extends the existing fingerprint paradigm by measuring additional biometrics associated with sub-surface finger tissue such as sub-surface fingerprints, sweat glands, and the pattern of the capillary bed to yield a user-friendly cost effective and anti-spoof multi-mode biometric solution associated with the finger. To our knowledge no other method has been able to capture sub-surface fingerprint, papillary pattern and horizontal vessel pattern in a single scan or to show the correspondence between these patterns in live adult human fingertip. Unlike many current technologies this approach incorporates 'liveness' testing by default. The ultimate output is a biometric module which is difficult to defeat and complements fingerprint scanners that currently are used in border control and law enforcement applications.
我们建议使用相关映射光学相干断层扫描（cmOCT）来提供与手指相关的其他生物识别特征，这些特征可以补充现有的指纹技术，用于执法应用。本研究通过测量与手指皮下组织相关的其他生物识别特征，如皮下指纹、汗腺和毛细血管床的模式，扩展了现有的指纹范式，从而提供了一种用户友好、经济高效且防欺诈的多模式生物识别解决方案。据我们所知，没有其他方法能够在单次扫描中捕获到皮下指纹、乳突模式和水平血管模式，也无法显示这些模式在活体成人指尖之间的对应关系。与许多当前的技术不同，这种方法默认包含“活体”检测。最终的输出是一个生物识别模块，该模块很难被攻破，可以补充目前在边境管制和执法应用中使用的指纹扫描仪。
