Implementation of a Security Access Control Model for Inter-organizational Healthcare Information Systems

The inability to share information across systems is just one of the major impediments in the health care business that hinders progress towards efficiency and cost-effectiveness. Workflow management systems are very popular and largely being used in a business environment for inter-organizations. This paper investigates workflow involvement of healthcare process in order to support and complement the transition of information and tasks among different healthcare organizations. This research examined dataflow between organizations. The purpose of this study is to propose a security access control model, based on role based access control, for integrating healthcare information systems of various healthcare organizations. A case study among pharmacies, hospitals and clinics is presented in this paper. Our experimental results show that this model is scalable and it can be easily extended to a pervasive computing environment.
