A user case from the Netherlands under the aegis of the Data Sharing Coalition brings positive news for those grappling with data sharing challenges. Private, public and the civil sector actors collaborated in a project that was based on cross-domain data sharing for the purpose of preventing and monitoring human trafficking. In this case, information obtained by law enforcement agencies of victims of forced prostitution was processed together with information from victims obtained by NGOs. The Sustainable Rescue Foundation (an NGO), Roseman Labs and others worked with privacy experts at Pinsent Masons to develop a system based on MPC (Multi-Party Computation) technology to help overcome the privacy law challenges so that sensitive data could be processed in confidence.
