Wrist vein patterns are acquiring increasing con-sideration in biometric recognition
application. Optical and near infrared technologies provide only 2D information. In this work …

Biometric systems based on ultrasound images are increasingly becoming popular and are
exploiting different characteristics like fingerprint, palmprint, hand geometry and palm vein …

In this work, an ultrasound technique for achieving 3D palm vein patterns for biometric
recognition purposes is proposed and experimentally tested. Commercial ultrasound …

A novel non-invasive imaging technique to image the vein patterns in various parts of the
hand for biometric purposes is evaluated. Two imaging methods are investigated: far …

Hand vein patterns are unique and universal. Vein pattern is used as biometric feature in
recent years. But, it is not very much popular biometric system as compared to other systems …
