Abstract

In this paper we discuss implementation issues of a distributed privacy enforcement scheme to support Owner-Retained Access Control for digital data repositories. Our approach is based on the Java Security Framework. In order to achievepolicy enforcement dependent on the accessed data object, we had to implement our own class loader that supports instance-level policy assignment. Access policies are described using XACML and stored together with the data as sticky policies. Enforcement of generic policies over sticky policy objects required the extension of XACML with XPath specific functions. Our use-case scenario is the user-controlled distribution of Electronic Health Records.
