Abstract—The objective of the paper is to propose a privacy centered process model for healthcare information system focusing on the trust between the entities, security methods and the resulting privacy assurance in the health information. The work addresses the criticality of the medical data and an adaptable security mechanism to prevent anticipated security risk in disclosing the allowable information. The trust between various covered entities including medical insurance agents is managed by a dynamic trust evaluation method in different process. The collaboration of various objects through inter process communication is achieved to determine the needed security method by an object in a different process. The permitted colored tokens help to detect the intruder or a fraud in submitting the same medical case many times. The cyclic processes and sub processes are simulated not only to determine the utilization of various resources of healthcare information system but also the sensitivity of the system in different scenarios.
Index Terms—Adaptable security, covered entity, fraud detection, process, resource utilization.
