TIMELY AND CONTROLLED INFORMATIONSHARING SYSTEM

During natural disasters or emergency situations, an essential requirement for an effective emergency management is the information sharing. In this paper, we present an access control model to enforce controlled information sharing in emergency situations. An in-depth analysis of the model is discussed throughout the paper, and administration policies are introduced to enhance the model flexibility during emergencies. Moreover, a prototype implementation and experiments results are provided showing the efficiency and scalability of the system.
