Biometric Authentication Based on Hand Vein Pattern
Recently, a new biometric technology based on human hand vein patterns has attracted the attention of many researchers. This chapter discusses vein pattern authentication, which uses the vascular patterns of the back of the hand as personal authentication data. Vein information is hard to duplicate because veins are internal to the human body. Vein authentication is one of the most accurate and reliable biometric technologies, which is widely employed in mission-critical applications such as banking, etc. A dynamic ROI extraction algorithm was presented through which more features can be extracted when compared to the fixed ROI. The extracted ROI was enhanced, and then the noise content was removed. The key features that represent the geometric information of the vein pattern were extracted; they are the bifurcation and ending points. This chapter presents a new vein pattern recognition system by assigning different weights to bifurcation and ending points. The approach is tested on a vein pattern database of 60 different hands. Experimental results show the approach achieves 2.5% of Equal Error Rate (EER) and recognition accuracy of 98.24%.
