정보 기술이 발전함에 따라 디지털 정보로 개인의 특성을 표현할 수 있는 방법들이 늘어나고 있다. 하지만 기존의 방법으로는 개인들을 제대로 식별하기 어려워지고 있다. 이를 해결하기 위해 여러가지 ID 관리 기술들이 등장하였지만, 오히려 다양한 ID 관리 기술들로 인해 상호운용성 문제가 우려된다. 오픈소스 형태의 ID 관리 프로젝트는 기존의 ID 문제뿐만 아니라 ID 관리 기술들의 상호운용성까지 해결해 주는 효과적인 방안이다. 최근 여러 업체들이 오픈소스 프로젝트에 주도적으로 참여하고 있으며, 대표적인 오픈소스 ID 관리 프로젝트로는 OpenSSO, Shibboleth, JAX-WS, OSIS, Higgins, Bandit, Heraldry가 존재한다. 본 고에서는 이들 프로젝트를 살펴봄으로써 오픈소스 ID 관리 기술의 현황과 장단점에 대해 알아 보았다.
