Free registration required

Executive Summary

The authors develop the foundations for a theory of Group-Centric Secure Information Sharing (g-SIS), characterize a specific family of models in this arena and identify several directions in which this theory can be extended. Traditional approach to information sharing, characterized as Dissemination-Centric, focuses on attaching attributes and policies to an object as it is disseminated from producers to consumers in a system. In contrast, Group-Centric sharing envisions bringing the users and objects together in a group to facilitate sharing.
