Abstract
This document describes the personal identification by using finger vein patterns, one
of the recent enterprizes conducted by the TRAFST (Transdisciplinary Federation of Science and
Technology). First, a brief review is given on the biometrics using finger prints and iris. Next,
an equipment of personal identification by using finger veins developed by Hitachi Co. Ltd. is
illustrated. Then diversity of human finger vein images is shown by extracting their patterns, by
using the equipment, from the right and left index fingers, and middle fingers of 506 person and
finally the usefulness of finger veins patterns for personal identification is shown by evaluating the
false acceptance rate (FAR) and false rejection rate (FRR). These rates depend on the cut-off point C;
when C = 0.295 those rates are estimated to be 0.00000001% and 0.00005%, respectively.
