Study on the Identity Authentication System on Finger Vein

With the development and progress of society, how to recognise human identity and protect information security is a social key problem that must be solved in current information age. Therefor, according to the stucture features of human finger vein image, from the secure and practical angle, the identity authentication system on CCD finger vein has been developed. This paper introduces the general system structure and its work principle, the process of figure vein feactures extraction in detail. The experiment results show that this system has higher accuracy. Its all misrecognition ratio is 1% and its accuracy rate is 99%. It is worth extending and applying.
