modeling users in role-based access control
The essential properties of a simple model for users, groups and group hierarchies for role-based access control, embodied in a group graph, are presented. The interaction between the group graph and the role graph model of Nyanchama and Osborn is shown. More complex models of users and their compatibility with the group graph model are discussed.
