Since its creation in 2014, the PRIVATICS project-team of Inria is working on privacy protection in the digital world: on one side, it aims at understanding the privacy research domain and its evolution, both from theoretical and practical aspects, and on the other side with a strong interest in designing and developing privacy-enhancing technologies, tools and systems. The approach taken in PRIVATICS is fundamentally inter-disciplinary and covers theoretical, legal, economical, sociological and ethical aspects by the means of enriched collaborations with the members of these disciplines.
