Abstract Details

2013, Master of Science in Engineering, University of Toledo, Engineering (Computer Science).
As information systems became widely used by organizations and enterprises, resource sharing and collaboration of work have been pervasive. As a natural way to realize this, delegation has become the routine rather than the exception. However, traditional delegation models have encountered various issues in meeting the growing and diverse requirements of different industries and customers. Some of them fail to provide sufficient delegation functionalities, while others are cumbersome to apply and manage practically. Therefore it is imperative to propose a flexible delegation model that provides fine-grained control in response to different scenarios. Meanwhile, such a model should be easy to apply and maintain. Base on that, this study set out to design a flexible delegation model based on role-based access control which supports fine-grained delegation control at both role and permission levels. Moreover, it introduces a dynamic delegation role structure to deal with different types of delegation requests so that the delegation model can cope with unexpected delegation cases. Finally, a prototype is implemented based on a healthcare information system to demonstrate the feasibility of the model.
