VEIN PATTERN MANAGEMENT SYSTEM, VEIN PATTERN REGISTERING DEVICE, VEIN PATTERN AUTHENTICATION DEVICE, VEIN PATTERN REGISTERING METHOD, VEIN PATTERN AUTHENTICATION METHOD, PROGRAM, AND VEIN DATA STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a vein pattern management system, a vein pattern registering device, a vein pattern authentication device, a vein pattern registering method, a vein pattern authentication method, a program and a vein data structure, enabling determination of the presence or absence of a false vein pattern artificially formed on the body surface.

SOLUTION: The vein pattern management system is provided with an imaging section for imaging the partial body surface of a living body by near-infrared light to generate near-infrared light imaged data, a vein pattern extracting section for extracting a vein pattern from the near-infrared light imaged data using a differential filter that outputs a large value in a pixel with a large difference from surrounding pixels with respect to a plurality of pixels constituting the near-infrared light imaged data, and a false vein pattern determining section for determining the presence of the false vein pattern artificially formed at a part of the imaged body surface based on the extracted vein pattern.
