Paper Abstract

In traditional fingerprint biometrics, fingertips stained with water, dust or fake fingerprints can lead to security issues such as false rejection and acceptance. It has been found in biology that the fingerprint pattern also exists in the papillary layer inside the fingertips, which is the source of the external epidermal fingerprint. Optical coherence tomography (OCT) is a noninvasive imaging technique that captures micrometer-resolution, three-dimensional images from within biological tissues. In this paper, a spectral domain OCT system is established to measure subcutaneous information from fingertips with large area and high resolution. A hybrid hierarchical clustering is proposed to identify the contours of the corneum stratum and papillary junction, with which the internal and external fingerprints can be extracted, respectively. The experimental results show that the external and internal fingerprints obtained by OCT have same pattern and almost same minutiae distribution. Thus the internal fingerprint can be a good replacement or complement of the external fingerprint, and the detection of internal fingerprint can defense against fake fingerprints.
