Critical information diffusion systems

Abstract

Today, individuals, companies, organizations and national agencies are increasingly interconnected, forming complex and decentralized information systems. In some of these systems, the very fact of exchanging information can constitute a safety critical concern in itself. Take for instance the prevention of natural disasters. We have a set of actors who share their observation data and information in order to better manage crises by warning the more competent authorities. The aim of this article is to find a definition to such kind of systems we name Critical Information Diffusion Systems. In addition, we see why Critical Information Diffusion Systems need information exchange policies.
