Abstract: Digital Rights Management(DRM) of digital documents is one of the important research fields of DRM. This paper presents a digital rights management scheme of PDF digital documents, whose rights management is based on a kind of dynamic logical license which owns a detailed control methods of document rights and an enhanced security by content grade encryption. The system model, implementation architecture and method are explained. A comparative analysis is showed and an application example is analyzed.
