스트리밍(Streaming)이란 인터넷을 통하여 영상, 음악 등 디지털 멀티미디어 데이터를 실시간으로 전송하여 재생할 수 있는 기술이다. 인터넷과 통신 기술의 발전으로 인해 기존 다운로드방식의 디지털 정보는 실시간 스트리밍 형태의 서비스로 변화하고 있다. 또한 디지털 정보의 제작과 유통상의 용이함으로 인해 디지털화된 동영상 제작이 증가하고 있다. 그러나 디지털 콘텐츠는 복제, 변형, 유포 등이 용이하고 안전하지 않은 인터넷을 통해 유통되고 있어 보안과 저작권 문제가 중요한 쟁점으로 대두되고 있다. 본 논문에서는 고품질의 스트리밍 서비스를 가능케 하는 MPEG-4를 대상으로 하여 스트리밍 환경에서의 콘텐츠 보호 방법에 대하여 설명한다.
