Withdrawn: Privacy in smart metering ecosystems

While smart metering is a key technology for reaching a sustainable consumption of resources, smart buildings are on their way to provide ubiquitous home automation. These technologies combine to frame a smart metering ecosystem with corresponding services and business models introducing new security challenges including privacy protection. This paper outlines a novel approach to provide customers of smart metering ecosystems with full control over their data in all areas of data collection, processing and exchange. The approach keeps the privilege model simple enough for regular users to understand how to configure their desired level of privacy. More concrete, we provide a simple, easy to use privacy dashboard that translates user input into XACML policies based on privilege modeling for this scenario. Generated XACML policies are evaluated upon receiving access requests to sensor data or actuators. Using the model proposed in this paper greatly improves user understanding and implementation of privacy rights related to smart metering ecosystems.
