In recent years, advanced in digital technologies have created significant changes in the way we reproduce, distribute and market Intellectual Property (IP). DRM for multicast contents is complicated risk, the further technology development and human demand, this approaching is still being researched by the scientist and all by the company which is conducting in piracy management reduced, and every country has national policy to make this consortium to limit piracy properties, based on this paper research development, just only two approaching to reduce piracy in DRM they are Industrial Property (IP) and Copyright. In this paper, we are not only figuring and analyzing about the processes to reduce and limit the piracy and unprotected copy law but also describing about the encryption process, watermarking and digital signature process algorithms. The basic concepts of this encryption process for web-based multicast content in DRM are implemented in Java. We conduct this method is a computerized through web based application system approaching to reduce unprotected copy and piracy. Which is used in DRM for multicast content in every section, by providing a fundamental in information technology development, we believe this research is reliable to prove that is unprotected copy, and piracy can be reduced by protecting with this paradigm.

최근 인터넷 이용자의 급증과 멀티미디어 컨텐츠의 증가로 인한 네트워크의 정체 현상을 해결하기 위한 방안으로 CDN 기술이 대두되고 있다. 본 논문에서는 멀티미디어 컨텐츠를 안정적이고 신속하게 전송할 수 있는 방안으로 CDN 인프라를 기반으로 하여 CDN 서버 그룹간의 멀티캐스트 전송과 CDN 서버와 사용자 사이에 다중 코딩과 다중 경로 전송을 제안하였다. 이러한 연구는 멀티캐스트 전송에 있어서의 비 신뢰성 문제를 해결하고 멀티미디어 컨텐츠의 전송 효율을 높여 웹 컨텐츠 분야의 새로운 비즈니스 모델 창출에 기여할 수 있을 것이다.
