Personal identification device and personal identification method using vein distribution pattern and integrated personal identification system using the same

摘要

According to the present invention, a vein pattern reflecting a vein distribution characteristic of an individual's hand is extracted, and the vein distribution characteristic is detected and classified in different databases according to the fluid artifacts of the individual. Thus, The present invention relates to a personal identification apparatus and method using a vein distribution characteristic, which enables comparison of processed distribution characteristics to enable faster personal identification. The apparatus includes a key input unit 1; An interface connector 2a; A microprocessor 3; A video memory 20a; A data memory 20b; A frame grabber 20c; A CCD camera 10a; Infrared light 10b; An infrared filter 10c; An infrared absorber 10d; Handle bar 30a; And a palm rest (30b), the method comprising the steps of: setting a certain area from the image data of the input hand; High-pass filtered image data in the set region; Binarizing the filtered image data; Detecting a vein distribution pattern by removing neurons of the binarized image; Obtaining a distribution characteristic from the detected vein distribution pattern; Storing the distribution characteristics in different databases in accordance with presence or absence of liquidity of the individual; Comparing the distribution characteristics and the pre-stored distribution characteristics, respectively; And recognizing that the person is a specific person according to the comparison result. Thus, it is more convenient and more accurate and effective invention by improving the identification speed and the recognition rate by selective storage according to personal characteristics.
