新型通用格式多媒体数字版权管理系统设计与实现
Design and implementation of a novel general format multimedia digital rights management system
摘要
Abstract
Aiming at the copyright protection of multimedia content, a novel general format multimedia digital rights management model was designed which includes encryption and packaging of content, key management, security engine, license management and distribution, DRM client, DRM management and other functional units. This model uses un-structured encryption method which overcomes the limitations of encryption method based on the content format to sup-port the general format multimedia. In addition, this model uses the license acquisition number as the only certificate to download license to solve the problem of license reissue and transfer, and supports fine-grained control model. Combined with this model, a multimedia digital rights management system was developed based on fixed and mobile converged services which is used in the field of digital consumer. The experimental results and practical application show that this scheme with good practice in the copyright protection of multimedia content does not affect the multimedia quality, and have high efficiency and safety.关键词
