Abstract
At present, in making to be a code number by bank ATM, the numeral of 4 digits is mainly used. On the other hand, card falsification and unjust photographing in the code number input don't decrease. Then, the contrivance that the numeral arrangement of input screen of the code number is changed has also done it. And, the bank which establishes the vein authentication system using palm and finger which entered the practical stage recently increases. However, though the technique according to the biometric information of the vein certification is the high security, since card falsification and unjust photographing are difficult, on the other hand the introduction cost of it becomes considerable large amount of money. And, though it is the biometric information of fingerprint and vein of hand, there is a case in which it can not be used by the failure. And, the certification which contacts the equipment can not deny either the psychological resistance. In this study, security key entry system using infrared camera is developed. This proposal system allocates four shape patterns of hands as a code number, and it is made to be the security key. As a result of application experiment to the security key, it succeeded in the certification of the security key, and the effectiveness was shown.
