인터넷의 급속한 성장으로 인하여 안정적인 보안수준을 제공하면서 사용이 편리한 사용자 인증 시스템의 필요성이 대두되었다. 90년대까지 사용자 인증 수단으로 많이 사용되던 개인장치나 비밀번호 등은 분실 가능성 및 도용의 위험이 있어 보안이 중요한 환경에서는 사용상의 제약이 따른다. 그러므로 이러한 제약을 보완할 수 있는 생체정보를 이용한 사용자 인증에 대한 관심이 꾸준히 증가하고 있으나, 생체정보는 비밀번호와 같이 사용자가 임의로 변경할 수 없으므로 외부로 유출된다면 심각한 문제가 발생할 수 있다. 본 고에서는 생체정보를 중앙 데이터베이스에 저장하지 않고 사용자가 휴대할 수 있는 IC 카드에 저장하고, 생체정보를 이용한 사용자 인증 과정도 IC 카드 내부의 프로세서를 이용하여 수행하는 Match-on-Card 기술 개발에 관하여 설명한다.
