Content protection is now becoming more and more important for Digital Rights Management (DRM), which involves rights embedding, identification, rights validation digital multimedia resource is popular in the real world, how to protect multimedia content from be violated without rights control is an important thing especially to resist copy-spread kind violation. In this paper, an novel approach for multimedia rights management is proposed based on partial encryption method, which can control multimedia resource played in a rights-constraint environment, which can protect multimedia resource from being copying and spreading, and in the authorization usage environment, the protected multimedia is properly played as normal, however once the resource is beyond the authorization environment, the protected resource will not be played correctly. Experiments showed our proposed partial encryption approach was efficient with real-time quality of service, which was suitable for online multimedia streaming in content delivery network.
