최근 디지털 콘텐츠의 지적 재산권 보호를 위한 디지털 워터마킹 기술 및 핑거프린팅의 연구가 활발히 진행되고 있다. DRM(Digital Rights Management)는 디지털 콘텐츠 지적 재산권 보호뿐만 아니라 콘텐츠에 대한 출판, 유통 및 사용에 필요한 관리와 보호체계이다. 본 논문에서는 콘텐츠 유통과정에서 발생할 수 있는 불법 복사와 같은 불법 행동에 대해 콘텐츠를 안전하게 보호하며 사용자에게 편의성을 제공 할 수 있는 프로토콜을 제시할 것이다. 이를 위해 콘텐츠 불법복사 및 불법사용을 방지할 수 있도록 은닉 에이전트(Hidden Agent)를 이용한다. 이 은닉 에이전트는 특별한 설치가 필요 없이 콘텐츠 내에 내포되어 있어 불법복사 및 불법사용에 대해 체크함으로써 불법복사의 사용을 차단할 수 있도록 한다. 또한 사용자들에게 숨겨져 있기 때문에 워터마킹의 역할 또한 대신할 수 있다.
