A Secure Confidential Document Model and Its Application

Many enterprises, organizations, governments and militaries are all facing a problem: how to protect their confidential documents, especially how to prevent them from being unauthorized copied or redistributed is a serious trouble as lacking of mechanism to forbid this action at present. In this paper we propose a Secure Confidential Document Model (SCDM). The document under the proposed model is divided into logical blocks based on the content, and a lot of useful information is also included in this model. So it can be easily and flexibly controlled in access and distribution no matter what format the document is. Moreover a record is also included in the proposed model so it will be easy to trace the confidential documents. A case of its application in confidential documents management system is introduced to illustrate the key ideas of the proposed document model.
