Personal identification device and method
First Claim
1. A personal identification system for executing a personal identification based on information of an IC card, the system comprising:
- an IC card reader for reading a registered feature information from the IC card without contacting the IC card; and
a personal identification device for executing the personal identification based on the registered feature information read from the IC card reader,wherein the personal identification device has a light source for applying a light to a hand, an interface for providing an area of the hand irradiated by the light in a non-contacting manner, an imaging device for imaging the light applied to the hand, and a calculation unit for extracting a feature information including a vein pattern imaged by the imaging device, andwherein the calculation unit executes the personal identification based on the registered feature information and the extracted feature information.

Abstract
The invention aims at providing personal identification in environments where non-contact is required, with high accuracy even though using a finger vein pattern images unclear and susceptible to positional deviations, wherein it has: a means for acquiring finger vein patterns without contact; a means for carrying out rotational correction using the outline of a finger as a method of taking out a vein pattern contained in the acquired image; a means for normalizing the position of the finger image with reference to the fingertip; a means for acquiring an overall vein pattern statistically by repetitively tracking regions of dark luminance intensities for a desired length from a desired position in the image; a matching means for comparing regions where vein patterns manifest vivid features; and a means for independent matching of subregions and evaluating positional deviations where matching is recognized.
