PPM: Privacy Policy Manager for Home Energy Management System
The smart grid has been a popular technology for the power grid system. In order to optimize the power supply and distribution, and to provide personalized services by service providers, the consumption data is collected from the smart meters through Home Energy Management Systems (HEMS). However, privacy concern has been a major issue for personal data utilization. This paper introduces a new personalized services architecture for HEMS service providers. Under this architecture access control for private information is separated from data storage by using a user’s customized privacy policy. Also, the architecture supports user-driven privacy policy management. The Privacy Policy Manager (PPM), a major component, has been designed for this purpose. PPM provides the following functionalities: privacy policy management, information flow control, and recording the flows.
