개인 식별에 이용되고 있는 생체정보로는 보편성, 독특성, 영구성, 수집 용이성의 특성을 보유하고 있는 지문(fingerprint), 장문(palm print), 족문(foot print), 얼굴인식(face recognition), 홍채인식(irisrecognition), 및 성문(voice pattern) 등을 이용하고 있다. 장문은 지문과 비교하여 특징점 이외에도 주요선, 주름, 특징점, 등을 보유하고 있어서 개인 식별의 장점을 보유하고 있다. 본 사례는 최근, 개인 식별에 대한 관심도가 증가하고 활용되기 시작한 손바닥(장문)에 대하여 부위별 명칭, 장문 부위별 채취 시주의점, 장문의 특징점 및 주요 선을 이용한 분류법 등을 소개하고 사례를 통하여 분류를 시도하였다. 한국인 장문의 주요선 유형을 분석하고자, 25명의 성인의 오른손, 왼손의 장문을 채취하였다. 1) 생명선과두뇌선의 관계에 따라 NORMAL, SIMIAN 및 SYDENY로 분류되며 주로 NORMAL 2종류에 해당되는사례가 오른손, 왼손이 모두 19명으로 대부분을 차지하였다. 2) 생명선의 분류로는 Branched type, Forkedtype, Accessory type, Broken type, Cascade type, 및 Soft type 등 6종으로 분류되며 오른손은 Accessorytype 8명, Forked type 7명 및 Soft type이 5명으로 대부분을 차지하였으나 왼손의 경우 Soft type이 12명,Accessory type 5명 및 Forked type 5명으로 다른 양상을 각각 보였다.
Abstract
Biometric information have many authentication applications because they have many characteristicproperties such as universality, uniqueness, permanence and collectability. The traits of biometrics, such asfingerprint, palm print, foot print, face recognition, iris recognition, voice pattern, do not change and it is difficultfor a person to alter his or her own physiological biometrics. The palm print contains three flexion creases,known as principal lines, secondary creases and ridges and these complex patterns of lines are very usefulin personal identification. This paper presents the features, ridge characteristic and types of palm print. In thiscase study, in order to classify types of palm print, we examined 25 palm prints of Korean adults, analyzedthe data according to the side of hand and types of principal line (heart line-head line, heart line). 1) Typesof the heart line-head line were classified into NORMAL, SIMIAN and SYDENY types. NORMAL 2 types,which accounts for the majority of the 19 people was confirmed. 2) Heart line is generally classified into aBranched type, Forked type, Accessory type, Broken type, Cascade type and Soft type. The palm prints ofright hand were classified into 8 Accessory type person, 7 Forked type person, 5 Soft type person, but in thecase of the left hand they were classified into 12 Soft type person and 5 Accessory type person in whichshowed different patterns.
