Finger vein system improves the performance of identification of system. Finger print sensor is used in biometric systems to make the system highly secure. In this paper a review of Fingerprint and Finger vein image processing is done. The purpose of finger vein system is to recognize the person’s identity by mathematical analysis of the patterns of finger prints which are visible from some distance. The block diagram describes the working of finger vein system. The Finger vein image processing makes our system more secure and overcome the threatens.
