Abstract: An iris recognition method and an apparatus for the iris recognition method are provided to detect the iris accurately and efficiently even though an eye is covered by eyebrows or an eyelid in an image of the eye. An iris recognition method includes a step of receiving an image of an eye(S100) and filtering the image with a threshold value to obtain a binary image(S105), a step of searching candidate central search regions for the pupil center using histogram information of the binary image(S110), a step of considering points belonging into the candidate central search regions in the binary image as candidate pupil center points and performing a masking operation on concentric circles obtained by varying the radius of a circle having each of the candidate pupil center points as a center point using eight pupil boundary mask templates to detect the boundary and the center point of the pupil(S115), and a step of performing a masking operation on concentric circles obtained by varying the radius of a circle having the detected center point of the pupil as a center point with six iris boundary mask templates to detect the boundary of the iris(S120).

Abstract: 본 발명은 입력된 지문 영상에 대하여 개인별 지문 특징을 융선의 기하학적 형태로 정의하고 융선의 배열 순서대로 정렬하여 등록 저장한 후, 저장된 융선의 상호 위치관계를 이용하여 지문을 인식하는 장치 및 방법에 관한 것이다. 즉, 본 발명은 지문 입력 수단을 통하여 입력되는 지문 영상을 데이터화함에 있어서, 융선의 모양 및 그 주변의 융선에 대하여 연결된 정보를 산출하고, 이를 개별 융선의 법선 방향과 연결 상태를 참조하여 고유한 순서로 정렬하여 저장하며, 이를 이용하여 비교 대상이 되는 지문에서 대응하는 하나의 융선을 탐색할 수 있으며, 이들 융선쌍으로부터 시작하여 순차적으로 연결 관계를 확인함으로써 전체 융선에 대한 탐색이 가능하며 이 과정에서 생기는 유사도를 판정하여 본인 여부를 판별함으로써 입력된 지문에 대한 인식과정에서 신뢰도가 향상되며, 특히 세선화된 작은 영역의 지문 영상만으로도 지문 인식이 가능하게 되어 융선의 개수도 작고 특징점의 개수는 더 작아지는 등 열악한 환경의 지문에 대하여도 오인식율을 현저하게 감소시킬 수 � �는 이점이 있다.

Abstract: PURPOSE: A device and a method for certifying a user using a fingerprint characteristic point are provided to match the characteristic point on a limited hardware resource environment such as a smart card and a USB(Universal Serial Bus) token by reducing the memory use for the entire bins, and to enhance the safety of the biometric data by preventing the fingerprint data of a user from leaking out. CONSTITUTION: A fingerprint image input part(10) provides a scanned fingerprint image for registration to a host(30) through an I/O(Input/Output) interface(20), scans the fingerprint image of the user wanting the certification, and provides the scanned fingerprint image to the host(30) through the I/O interface(20). The host(30) includes a CPU(32) and a memory(34). The CPU(32) extracts the characteristic point from the fingerprint image for the registration, and simultaneously provides it to the memory(34) and a security token part(40).
