Abstract

New advances in information and communication technologies (ICT) and their incorporation into the medical domain have created opportunities to enhance medical services and provide improvement to workflow at a low cost. However, to implement such services, the current medical system needs to be integrated, secured, and available to health professionals and patients. In this paper, we propose an infrastructure that suggests the use of techniques and standards such as: cooperative multi-agents, standards for user authentication and service authorization, as well as protocols for cross-enterprise document sharing. The proposed infrastructure allows for integration of a PACS (Picture Archiving and Communication system) with a widely accepted HL7 (Health Level Seven) standard infrastructure for provisioning nation-wide electronic health records (EHR). In this approach, the cooperative agents provide: i) an action-based access control mechanism to share medical images that allow safe integration of a PACS and the Diagnostic Image Repository (DI-r) systems within a standard EHR system; and ii) a behavior-pattern based security polity enhancement to assist the system administrator. Such secure and interoperable medical imaging systems are easy to expand and maintain.
