Finger vein biometric: Smartphone footprint prototype with vein map extraction using computational imaging techniques

A new vein structure based biometric approach is introduced in this paper. The idea is to use the finger vein structure in the intermediate phalange to identify or authenticate individuals. The concept of the hardware is to be implementable in handheld devices. Hardware configuration and software implementation are presented. The idea of temporal median filter was used in order to fuse finger images and Gabor filter bank was implemented to extract the finger vein maps.
