Palm Vein Technology Blood Vessels uses in Security

Palm vein recognition is a unique vascular recognition technique used for identification of individual. In this paper presents a review on the palm vein authentication device that uses blood vessel patterns as a personal identifying factor. The vein information is hard to duplicate since veins are internal to the human body. The palm vein authentication technology offers a high level of accuracy. Palm vein authentication uses the vascular patterns of an individuals palm as personal identification data. Compared with a finger or the back of a hand, a palm has a broader and more complicated vascular pattern and thus contains a wealth of differentiating features for personal identification. The importance of biometrics in the current field of Security has been depicted in this work comparison between different techniques and their advantages and disadvantages in this paper. The vein information is hard to duplicate since veins are internal to the human body. The design details of the palm vein capture device are researched, and preprocessing and feature extraction of palm vein image are also investigated. A small palm vein image database is built by the proposed capture device. Experimental results on the small palm vein database show that the designed system achieves an acceptable level of performance. Several banks in Japan have used the palm vein authentication technology for customer identification since July 2004. In addition, Fujitsu has integrated the technology into the access control of electronic door lock systems. Fujitsu plans to further expand applications for this technology by downsizing the sensor and improving the verification speed.
