Abstract
A method using optical coherence tomography to capture the microvascular network of the superficial layer of the finger skin for the purpose of fingerprint authentication and liveness detection. At the dermal papilla region, the vascular pattern follows the same pattern of the fingerprint and this vascular pattern forms a live vascular fingerprint. This live vascular fingerprint provides for ultrahigh security and a unique way for fingerprint-based personal verification. Because the system is based on blood flow, which only exists in a living person, the technique is robust against spoof attaching. After performing non-contact in-vivo imaging of a human fingertip, a three dimensional vasculature image is reconstructed from a plurality of vasculature tomography images and at least one vasculature fingerprint image which corresponds to the fingertip is extracted from the three dimensional vasculature image. This extracted image may then be compared to known fingerprint database for authentication or for liveness detection.
