- W1840370087 abstract "라이선스 메커니즘은 DRM(Digital Rights Management) 시스템의 핵심 요소 중의 하나이다. 라이선스 메커니즘은 DRM 시스템의 자원(resources), 자원의 사용 주체(principals), 자원에 대한 사용 규칙(usage rules) 등을 명확하게 식별하고 강제하기 위한 핵심적인 기능을 담당하도록 설계된다. 하지만 기존의 라이선스 메커니즘들은 가정이나 회사의 어떤 부서와 같은 그룹 내의 멤버들이 어떤 컨텐츠론 공유하고자 할 때 공유에 관련된 융통성이 부족하다. 본 논문은 그룹에 등록된 여러 명의 멤버들이 DRM 기술로 보호된 디지털 컨텐츠를 안전하고 융통성 있게 공유할 수 있도록 하는 새로운 라이선스 메커니즘을 제안한다. 본 논문이 제안하는 멤버/그룹 라이선스 메커니즘은 그룹 라이선스, 멤버 라이선스, 허가들(grants)간의 파생 관계 등의 개념들을 도입하여 기존의 라이선스 메커니즘을 확장한다. License mechanisms are the key elements in almost all DRM(digital rights management) systems. The license mechanisms are designed for the clear identification and enforcement of contents, principals, and usage rules in DRM systems. But current license mechanisms are lacking in the flexibility for the secure and efficient sharing of the contents among the members of a group such as a family or a part of an enterprise. This paper suggests a new license mechanism for efficient and secure sharing of contents in DRM systems among the members of a group. We named it member/group license mechanism. The mechanism extends the current license mechanisms by introducing new concepts such as group licenses, member licenses, and derivation relationships between licenses." @default.
