Open Trusted Health Informatics Structure(OTHIS)

摘要

The potential for development and deployment of trusted health information systems (HIS) based upon intrinsically more secure computer system architectures than those in general use, as commodity level systems, in today's marketplace is investigated in this paper. A proposal is made for a viable, trusted architecture for HIS, entitled the “Open Trusted Health Informatics Structure (OTHIS)”, based upon a set of separate but connected trusted modules. OTHIS addresses privacy and security requirements at all levels in an HIS. In this paper, we are concerned with the role of trustworthy access control mechanisms in HIS architectures. Our proposed OTHIS architecture gives direction on how trustworthiness in HIS can be achieved.
