Abstract

생체 지문과 모조 지문을 구별할 수 있는 생체지문 판단장치 및 그 판단방법이 개시된다. 본 발명의 지문인식장치는 생체 지문이 가지는 특이한 색상과 생체 지문이 지문입력창에 접촉함에 따른 접촉 압력변화에 의한 지문 색상의 변화를 이용하여 해당 지문이 생체 지문인지 여부를 판단한다. 지문인식장치는 컬러 영상센서를 이용하여 획득한 지문 영상으로부터 색상정보와 접촉 압력의 변화에 따른 색상변화정보를 계산하고, 계산된 색상정보가 기준 색상범위 내에 속하는지 여부 및/또는 색상변화정보가 기준 조건을 만족하는지를 판단함으로써 해당 지문이 생체 지문인지를 판단한다.
