A finger vein authentication device includes a finger information register unit for extracting information of a vein pattern from a vein image and registering the same as a matching template in a memory, and a finger vein authentication unit for extracting information of a vein pattern from the vein image and matching the same with the matching template to perform personal authentication. The device includes a finger image processing unit for extracting characteristics data of the finger from the vein image and a finger placement state determining unit for determining whether a placement state of the finger is good or not according to whether the characteristics data of the finger is within a predetermined range or not. If the determination result of the finger placement state determining unit is not good, the user is instructed to correctly place the finger by a picture output unit and/or a voice output unit, and the vein image is obtained again. |
