Hierarchies in Contextual Role- Based Access Control Model ...
Abstract. Hierarchical representation is a natural way of organizing roles in role-based access control systems. Besides its advantages of providing a way of establishing parent-child relationships among different roles, it also provides a facility to design and organize context dependant application roles that users may activate depending on their current context (spatial, temporal) conditions....
A Role and Context Based Access Control Model with UML
As the wide uses of access control model in systems, a more agile access control model is required to solve complicated modeling, user authorizing and verifying problem. In this paper, an access control model based on the concepts of role, attribute and context, named C-RBAC, is proposed.

Separation of Duty and Context Constraints for Contextual ...
This paper presents the separation of duty and context constraints of recently proposed Contextual Role-Based Access Control Model C-RBAC. Constraints in C-RBAC enabled the specification of a rich set of Separation of Duty (SoD) constraints over spatial purpose roles. In healthcare environment in which user roles are position and are purpose dependant, the notion of SoD is still meaningful and ......

The current approaches of the access control rest on the three entities (subject, action, object) to control the access the policy specifies that some subject has the permission to realize some action on some object.. OrBAC allows the policy designer to define a security policy ......
