In this paper, we implemented embedded LNUX-based UI(User Interface) board which can be applied to Human Iris recognition product. for this purpose, we also analyzed and designed LNUX operating system and adapted boot loader, kernel, control program modules according to the developed H/W architectures. As the experimental results shows that Iris recognition system is operable and embedded LNUX-based UI board which is connected to heterogeneous system by TCP/IP protocol can both successfully send and receive data this UI board has been able to obtain high performance.

범용적으로 쓰여지고 있는 id카드를 이용한 출입방식의 경우 카드 분실, 미소지시 또는 손상시 불편함을 초래하며 실질적인 보안의 효과를 기대하기에는 부족한 부분이 많은 실정이다. 또한 전국에 사업장을 가지고 있는 기업의 경우는 보안업체별 소스코드를 공개하지 않음에 따라 id카드를 통일하기 위하여 최초 설치 업체에 종속되는 문제점도 가지고 있다. 그리고 지문인식, 홍체인식 및 정맥인식 등은 출입통제시스템 자체의 단점과 더불어 이용자들의 불편함 그리고 정보수집에 따른 불쾌감을 발생하는 문제점을 가지고 있다. 이러한 단점을 극복할수 있는 얼굴인식 시스템의 경우 다양한 상황에서의 얼굴 검출 및 정보 처리등에 대한 문제점이 있어 정지화상이나 신분증에 화상데이타를 입력하여 비교하는 방법등에 대한 실용화가 많이 되어지고 있는 실정이나 이 역시 id카드가 없으면 출입이 허가되지 않는다는 문제점이 있다. 이러한 문제점을 극복하고 자연스러운 상태에서 인증 및 출입이 허가된다면 가장 이상적이고 경제적인 출입통제시스템 구축이 가능하므로 본 논문에서는 위 문제점에 대한 대안을 제시하고 증명을 통하여 현장에서 충분이 적용될 수 있음을 입증하고자 한다.

The human effort to make personal privacy and safety from outer environment has brought the improvement of security system through the technological development. Especially as a apartment dwelling and lifestyle is general, the role and function of door lock system is more important than ever. The research for user-centered approach and design on the door lock system should be implemented under the circumstances. This study has focused on the development of making safety as well as easy interface to design door lock system. The price also is competitive as compared with other door lock products. The goal of this study is to propose the alternatives not only to develop door lock design but also to search the innovative way of locking system design.

With the advance of ICT, the necessity of user authentication to verify the identity of an opponent online not face to face is increasing. The authentication, the basis of the security, is used in various fields. Because ID-based authentication has weaknesses in terms of stability and losses, two or more than two authentication tools are used in the place in which the security is important. Recently, biometric authentication rather than ID, OTP, SMS authentication has been an issue in terms of credibility and efficiency. As the fields applied to current biometric recognition technologies are increasing, the application of the biometric recognition is being used in various fields such as mobile payment system, intelligent CCTV, immigration inspection, and access control. As the biometric recognition, finger print, iris, retina, vein, and face recognition have been studied actively. This study is to inspect the current state of domestic and foreign standardization including understanding of the face recognition and the trend of technology.

There is a variety of researches about recognition system using biometric data these days. In this study, we propose a new algorithm, uses simultaneous equation that made of the edge of objects, to segment an iris region without threshold values from an anterior eye image. The algorithm attempts to find a center area through calculated outskirts information of an iris, and decides the area where the most points are accumulated. To verify the proposed algorithm, we conducted comparative experiments to Hough transform and Daugman's method, based on 50 images anterior eye images. It was found that proposed algorithm is 5 and 75 times faster than on each algorithm, and showed high accuracy of detecting a center point (95.36%) more than Hough transform (92.43%). In foreseeable future, this study is expected to useful application in diverse department of human's life, such as, identification system using an iris, diagnosis a disease using an anterior image.
