| 摘 要： | 针对现有保护技术不能满足数字内容全生命周期保护的问题，提出数字内容全生命周期保护的概念及保护模型，用“壳”封装数字内容形成壳式保护对象(BCO)，监管和保护数字内容生命周期的每个阶段。讨论BCO的逻辑结构、物理结构及物理耦合形式，结合应用实例描述基于PKC的关键Web服务，通过实例验证保护模型的合理性。

| Abstract: | Aiming at the problem that current protecting technology has not provide the lifecycle security for the digital contents,this paper puts forward the Content Lifecycle Protection（CLP） concept and the corresponding protection model,which mainly employs ＇Box＇ to wrap content into BCO so that box can supervise and protect inside content during each phase of lifecycle.By analyzing the elements in BCO,it presents BCO logical structure,physical structure and physical coupling structures respectively.The application experiment is implemented and key Web services based on PKC are described in detail,which proves the model＇s reasonability. |
