Comprehensive privacy mechanisms are essential in the pervasive internet-of-things systems of today, which are comprised of multiple distributed devices and diverse software stacks, while located in different legal or administrative domains. In such systems, often consisting of resource-constrained devices, guarantees of correctness and conformance to privacy policies is required, while data need to be synchronized among different software components. Motivated by the "data protection by design and by default" principle, we propose a technical framework to support data synchronization among edge components tailored for pervasive IoT applications. Our privacy-driven synchronization approach is based on a generically applicable privacy model and able to capture roles and permissions, actions on data, conditions and obligations that arise in privacy requirements. For automated and correct reflection of synchronized data among components, we adopt bidirectional transformations, a mechanism where synchronization between models, consistency, and well-behavedness are formally guaranteed. Thus, automatically generated privacy-aware data transformations are correct by construction. We evaluate POET, our framework and accompanying tool with a case study on medical information privacy and demonstrate its performance in resource-constrained edge devices.
