Analysis of Digital Content Nested Protection in the Research of Digital Content Lifecycle Protection

Abstract

Content Lifecycle Protection (CLP) employs 'Box' to wrap content into BCO so that Box can supervise and protect inside content during each phase of lifecycle. BCO is the core of CLP. In this paper, based on the CLP concept, we analyze the content nested protection and present the BCO physical coupling structures after the nested protection. At the end of this paper, the application experiment is implemented and shows how the BCO works in the content twice-nested protection.
