Presented is a new characteristic that can be integrated in a multimodal biometric system based on palm or hand geometry: the ridge and valley pattern of the skin of the hand's palm over the second metacarpal bone. Following a digital image enhancement, binarisation and thinning algorithm to obtain the thinned ridge map, the verification system performs a matching based on ridge endings and bifurcations. A performance of EER=0.017 is obtained from 4332 tests using 38 individuals.
