OPAL project presents a practical and open-sourced query-based platform for privacy-preserving large scale location data analytics. The project website provides more details on the project. At Imperial, I worked with Axel Oehmichen, Andrea Gadotti and Yves-Alexandre to build the system. The open-sourced code can be found here. The paper describing and evaluating the platform has been published at IEEE BigData 2019. The platform was deployed in Colombia and Senegal with the help of partners in those countries.
