This paper examines the access control requirements of distributed health care information networks. Since the electronic sharing of an individual's personal health information requires their informed consent, health care information networks need an access control framework that can capture and enforce individual access policies tailored to the specific circumstances of each consumer. Role Based Access Control (RBAC) is examined as a candidate access control framework. While it is well suited to the task in many regards, we identify number of shortcomings, particularly in the range of access policy expression types that it can support. For efficiency and comprehensibility, access policies that grant access to a broad range of entities whilst explicitly denying it to subgroups of those entities need to be supported in health information networks. We argue that RBAC does not support policies of this type with sufficient flexibility and propose a novel adaptation of RBAC principles to address this shortcoming. We also describe a prototype distributed medical information system that embodies the improved RBAC model.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
