HUMAN IDENTIFICATION USING FINGER VEIN IMAGES

Abstract

Finger vein is a unique physiological biometric which is used for identification of individuals based on the physical characteristics and parameters of the vein patterns in the human body. This technology is at present in use or development for a wide range of applications, which includes credit card authentication, security in automobile, employee time and tracking attendance, computer and network authentication, security at end points and automated teller machines. The basic principle, different feature extraction techniques and performance measuring are analyzed. Mostly the existing work is functionally described and compared in three parts (i.e. Finger vein acquired image, pre-processing and feature extraction).
