Self-Protecting Documents for Cloud Storage Security

Information security is currently one of the most important issues in information systems. This concerns the confidentiality of information but also its integrity and availability. The problem becomes even more difficult when several companies are working together on a project and that the various documents “go out of” their respective information systems. We propose an architecture in which the documents themselves ensure their security and thus can be exchanged over uncontrolled resources such as cloud storage or even USB flash drives. For this we encapsulate within the document itself some security components (e.g. access control, usage control) to achieve an autonomic document architecture for Enterprise DRM (E-DRM). Using such self-protecting documents, a company can ensure security and privacy for its documents when outsourcing storage services (e.g. cloud).
