Abstract

In this paper we present a model that can prevent conflict situations caused by applying both positive and negative authorizations for access to a resource. Such conflict situations may occur if an organization has decentralized administration, and/or several collaborating organizations have access to one resource and some of them apply positive authorizations while others apply negative authorizations. The proposed solution involves Belnap's logic.
