Abstract

Recently research is more focused on security integration policy and conflict reconciliation among various healthcare organizations. However, it is necessary to identify various inconsistencies between security policies through logical reasoning and to provide suggestion to solve inconsistencies for cross-organization collaboration. Besides that, existing approaches in security policy integration and conflict reconciliation did not concern about a security privacy access control model. This may cause unauthorized access to sensitive information in electronic medical records. Hence, it is important for us to investigate the security privacy access control model considering temporal and spatial context constraints in order to integrate security policies for collaborations among organizations to tackle such a need. In this paper, we propose a security privacy access control model, based on role-based access control (RBAC) considering temporal and spatial context in security policies integration and conflict reconciliation. Besides that, we need to investigate the type of conflicts and how to identify inconsistencies between policies from different healthcare organization collaboration.
