A prototype for solving conflicts in XACML-based e-Health policies.
CBMS(2013)
摘要
The Electronic Patient Record (EPR) enables the sharing of medical documents among several and widespread healthcare organizations. To guarantee privacy properties, access control policies should be defined, regulating how the documents can be shared. Conflicts may occur among policies applicable to the same access request. We present a running prototype, based on an XACML engine, that implements a conflict resolution strategy as an extension to the standard combining algorithms of the XACML engine. We evaluate the efficiency of our proposal in terms of execution time, on a variable number of conflicting rules.
