Visitor Access Control Scheme Utilizing Social Relationship in the Real World

Abstract : Access control to resources is one of the most important technologies for supporting human activities in the digital space. To realize the control two schemes were proposed: RBAC (Role-Based Access Control) and TRBAC (Temporal Role-Based Access Control) by adding time constraints and role dependencies to RBAC. However, these methods are not effective for temporal activities such as visitor access because of maintenance costs and inadequacy in safeness. In this paper, we focus on a visitor access control in the real world, by utilizing relationship with users and situations, and propose a novel access control scheme which is effective for temporal activities.
