초록

DRM이 최근에 많은 사이트에서 제거되어짐에 따라 비디오 서버 상에서 콘텐츠 보호는 중요해졌다. 그러나 기존에 존재하는 보호 방법들은 한계 들을 가지거나 스트리밍 성능을 저하시키므로 사용되어지지 않는다. 본 논문은 eCryptFS와 SELinux를 사용하는 콘텐츠 보호 방법을 제안하고 다양한 벤치마크들을 사용하여 제안한 방법의 성능을 측정한다. 그런 후 본 논문은 제안한 방버이 다른 성능 들은 저하시키지만 스트리밍 성능은 저하시키지 않아서 콘텐츠 보호를 위하여 사용할 수 있다는 것을 증명한다.

As a DRM is recently being removed from many sites, the content protection on a video server becomes important. However, many protection methods have their own limitations, or aren't used due to the deterioration of the streaming performance. This paper proposes a content protection method that uses both the eCryptFS and the SELinux at the same time, and measures the performance of the proposed method by using various benchmarks. Then, this paper verifies that the method doesn't significantly decrease the streaming performance although the proposed method decreases the other performances, so it can be used for the content protection in a multimedia system.
