Data-Centric Privacy Policies for Smart Grids

Smart cities and smart grids heavily depend on data being exchanged between a large number of heterogeneous entities. Parts of the data which such systems depend on are relevant to the privacy of individuals, e.g., data about energy consumption or current location. We assume the use of semantic technologies for data representation and exchange, and express privacy requirements as formal policies. We take a data-centric view, that is, we attach policies that restrict isolated uses of data to the data directly. When systems exchange data, they also exchange the policies pertaining to the exchanged data. The main benefit of such an approach over a system-level view is that our data-centric approach works in scenarios without central control.
