(Korean Abstract)
본 논문에서는 공개키 기반 등록기관의 사용자 신원 확인 기능의 안전성과 신뢰성 향상을 위한 방법으로 홍채인식 기술을 활용한 등록기관 시스템을 제시한다. 제안하는 시스템은 홍채 패턴의 처리 기능에 따라 홍채영상 획득, 홍채정보 등록, 홍채정보 검증의 세 개의 모듈로 구성되며, 각 모듈간의 등록정보의 교환은 대칭키 암호 알고리즘으로 암호화를 해서 안전하게 송수신이 이루어진다. 홍채 패턴의 효율적 표상과 비교를 위한 홍채 특징 정보의 추출 방법으로서는 웨이브렛 변환을 이용한 영상의 다중분할 과정을 통해 적은 차원의 정보를 추출하여 효과적인 특징벡터를 구성하는 방법을 사용한다. 적용된 홍채인식 방법에 대한 실험을 통해서, 생체인식 기술의 새로운 분야로의 적용 가능성을 살펴본다.

(English Abstract)
In this paper, a new approach to building a registration authority for issuing PKI-based certificates is presented to make the process of identifying an individual more secure and reliable by utilizing human iris recognition technology. The tasks of the proposed system associated with the manipulation of irises except for the general functions of registration authorities can be categorized into three modules, the acquisition of iris images, the registration of iris information, and the verification of users by means of iris patterns. The information among the three modules is safely exchanged through encryption and decryption with a symmetric cryptographic method. As a feature extraction method for a given iris image, a wavelet transform is applied to represent a feature vector with a small dimension of information obtained by subsampling an image corresponding to lower frequency bands successively without loss of information. Through the experiments on human iris recognition technology we proposed and applied to the registration authority, the potential of biometric technology in various applications is confirmed.
