Challenges of User-centric Privacy Enhancing Technologies

The GDPR promotes the principle of Privacy by Design and Default, acknowledging that the individual’s privacy is best protected if privacy law is complemented by privacy enhancing technologies (PETs). While technically advanced PETs have been researched and developed in the last four decades, challenges remain for making PETs and their configurations usable. In particular, PETs are often based on “crypto-magic” operations that are counterintuitive and for which no real-world analogies can be easily found.
