Using fingerprints as a method to identify an individual has been accepted in forensics since the nineteenth century, and the fingerprint has become one of the most widely used biometric characteristics. Most of the modern fingerprint recognition systems are based on the print pattern of the finger surface and are not robust against spoof attaching. We demonstrate a novel vital vascular fingerprint system using Doppler optical coherence tomography that provides highly sensitive and reliable personal identification. Because the system is based on blood flow, which only exists in a livng person, the technique is robust against spoof attaching.
自19世纪以来，使用指纹作为识别个人的方法已在法医学中被接受，指纹已成为使用最广泛的生物特征之一。大多数现代指纹识别系统基于手指表面的纹路图案，并且对伪造攻击的抗性不强。我们展示了一种使用多普勒光学相干断层扫描的新型重要血管指纹系统，该系统提供高度灵敏且可靠的个人识别。由于该系统基于仅存在于活体中的血流，因此该技术对伪造攻击具有抗性。
