Comparison of Near and Far Infrared Vision for Biometric Applications

In this paper, we provide the idea of analyzing the infrared vein patterns in the back of the hand combined with the appendant optical picture of the back of the hand for biometric purposes. We present results of an experiment which will demonstrate differences between near infrared and far infrared images as initial images for creating templates for biometrical purposes. Near infrared images offer a good quality for extracting hand veins on the one hand but contain no thermographic information as far infrared images do. The idea of this paper is to make counterfeit more difficult by using the infrared image with thermographic information and the appendant optical image with spatial information. That is why only far infrared images are useable in this case. This Paper will show a possibility to create a biometrical template based on far infrared images.
