Abstract

This paper presents encryption techniques for digital right management solutions of MPEG-4 streams. MPEG-4 is a format for multimedia streaming and stored in the MPEG-4 file format. We designed three kinds of encryption methods, which encrypt macro blocks (MBs) or motion vectors (MVs) of I-, P-VOPs (Video Object Planes), extracted from the MPEG-4 file format. We used DES to encrypt MPEG-4 data Based on theses three methods, we designed and implemented a DRM solution for an Internet broadcasting service, which enabled a MPEG-4 data streaming, and then compared the results of decryption speed and quality of rendered video sequences to get an optimal encryption method.

본 논문에서는 MPEG-4 스트림의 디지털 저작권 관리(DRM)를 위한 암호화 방법을 제안한다. MPEG-4는 멀티미디어 스트리밍을 위한 표준이며 MPEG-4 파일 포맷에 따라 저장된다. 인가된 사용자들만 접근이 가능하도록 MPEG-4 파일 포맷으로부터 추출된 I-VOP, P-VOP의 매크로 블록(MB)들과 모션 벡터(MV)들을 암호화하는 3가지 방법을 설계하였고, MPEG-4 데이터의 암호화에는 DES(Data Encryption Standard)를 사용하였다. 이러할 암호화 방법을 기반으로 MPEG-4 데이터 스트리밍을 위한 인터넷 방송 서비스용 DRM 솔루션을 구현하고, 최적의 암호화 방법을 선택하기 위해 복호화 속도 및 영상의 품질을 비교하였다.
