In this chapter Christina Koumpli answers Matthieu Caron's questions in turn: 1. Data protection has become a major issue. Why is this? Is it now a human right or a fundamental right? 2. Does France protect its data properly? Could it draw inspiration from foreign laws to improve data protection? 3. What two concrete measures should be taken, at French or European Union level, to improve data protection? 4. Can links be made between personal data protection and digital sobriety? Is data protection a possible/mandatory step towards a more sustainable digital world?
