Modelling of Integrated Trust, Governance and Access safi.re: Information Sharing Architecture

We live in a world where trust relationships are becoming ever more important. This paper outlines how an architecture which abstracts these relationships between domains, organisations and units, into a formal definition, and then implement these as governance rules, and using the trust relationship definition, and the rules. It defines the novel information sharing achitecture known as safi.re (Structured Analysis and Filtering Engine), which has been used on a number of information sharing projects, including within health and social care integration, and in sharing between the police and their community partners. The paper also outlines the novel architecture used for information sharing and the modelling of trust relationships using Binary Decision Diagrams (BDDs).
