Biometric Recognition Based on 3D Ultrasound Wrist Vascular Patterns

Biometric systems based on ultrasound images are increasingly becoming popular and are exploiting different characteristics like fingerprint, palmprint, hand geometry and palm vein patterns. In this work, a recognition system based on 3D ultrasound wrist vein pattern is proposed and experimentally tested. Recognition performances are evaluated with verification and identification experiments carried out on a preliminary database composed of 54 samples. Both experiments demonstrate that 3D methods improve recognition capabilities over 2D ones.
