Abstract: The dynamic nature of operations in organizations has led
to an interest in roles and permissions delegation to enable a seamless
continuity of business. Delegation involves assigning a given set of access
rights from one user to another. In existing role delegation models, delegation
is often authorized and controlled by a relation that specifies who
can delegate to whom. The usage of such relations in delegation models
has some disadvantages; such as complexity of maintenance, error
proneness, inconsistencies and inabilities to define some organizational
policies related to delegation. In this paper, we propose a new delegation
model that depends on organizational lines of authority to authorize
and control delegation. The main advantages of this approach are that
it simplifies the management of delegation authorization and complies
with organizational behavior. Furthermore, it eliminates inconsistencies
related to changes to roles and permissions.
