Abstract

The accountability of cloud service which provides the cloud users with accountable services applies various technologies such as the compliance of service policy, monitoring and auditing, logging, and others. It ultimately intends to provide trustworthy cloud service by determining who is accountable for various problems happened during data processing and service offering. In this paper, we propose a cloud ecosystem formed from the chain of content and DRM Cloud service in order to offer secure and trust DRM cloud service when providing high value-added content service. Besides this, we analyse the requirements of cloud services for content owners and users and then propose some logging information to be recorded for trace of accountability and a structure of tool for monitoring.

클라우드 사용자들에게 책임 있는 서비스를 제공하는 클라우드 서비스의 책임 추적성(accountability)은 서비스 정책 준수, 모니터링 및 감사(auditing), 로그 정보 기록(logging) 등과 같은 여러 가지 기술을 적용한다. 궁극적으로 데이터 처리, 서비스 제공 과정에서 발생되는 여러 가지 문제들에 대해 누가 책임이 있는지를 판단함으로써 신뢰되는 클라우드 서비스를 제공하는 것을 목적으로 한다. 먼저, 부가가치가 높은 콘텐츠 서비스 제공 시에 안전하고 신뢰되는 DRM 클라우드 서비스를 제공하기 위해 본 논문에서는 콘텐츠 및 DRM 클라우드 서비스 체인을 이루는 클라우드 에코 시스템을 제시한다. 또한 콘텐츠 소유자와 콘텐츠 사용자의 DRM 클라우드 서비스에 대한 요구사항을 분석하고, 책임 추적을 위해 기록해야 할 로그 정보 및 모니터링 툴 구조를 제안한다.
