Streaming media is widely adopted by thousands of applications in cloud computing, how to effectively protect streaming media contents is a new challenge. In this paper, we propose an efficient online digital rights management (DRM) scheme supporting dynamic license in cloud computing. The content provider encrypts media content and outsources the encrypted content to cloud storage, while the user acquires dynamic license from the license server and consumes the streaming media content from the cloud storage. Further, we present a secure key distribution protocol based on proxy re-encryption, which protects the confidentiality of content encryption key, and reduces the work of key management in the cloud, and also supports domain key to realize user domain management. In addition, we develop a prototype system with Google cloud storage APIs based on the proposed scheme, and the implementation and comparison results show that the proposed scheme satisfies the requirements of online media content protection in cloud computing.
