Abstract
In view of the fact that the reproducibility of a finger vein pattern is deteriorated in an image of the finger vein due to external scattered light, displacement, change in the amount of blood flow and the like, a multiple-valued pattern matching method is adopted so that such changes can be dealt with by converting a data map itself into a multiple-valued map.
