Novel finger vascular pattern imaging device for robust biometric verification

The vascular pattern of the finger has emerged as a promising new biometric modality, characterized by very low error rates, good spoofing resistance and user convenience when compared with other existing biometric modalities. In this paper, we present a new sensor design that is not only cost effective but also robust enough to capture the finger vascular (or finger vein) pattern. We evaluate the previously proposed finger vein verification approaches and also propose a new scheme that illustrates its superiority over existing approaches. Extensive experiments are carried out on the newly developed database constructed using our newly designed finger vein imaging sensor that comprises of 1780 finger vein samples corresponding to 89 unique fingers from 32 subjects. The data is collected in two different scenarios shows the efficacy of the proposed sensor as well as the proposed scheme.
