A Flexible Model and System Design of Access Control based on Social Relationships

摘要

This paper introduces the notion of social relationship based access control and creation of trusted communities through negotiation and collaboration. Users in cyberspace can chose to form ad hoc societies which share, in a trusted manner, resources in order to achieve a common goal. Our goal is to create an automated and secure access control system which will grant permissions to different resources according to each user's level of trust within a certain society. In this paper, we define two types of interactions: F1 - the interaction between a user and the underlaying system, and F2 - the interactions between users. Then, we propose the concept of social based access control and the creation of trusted communities.
