Privacy Engineering

In the light of omnipresent digitization, privacy challenges become increasingly prominent. Privacy Engineering is an emerging field of research and practice that takes the more „traditional“ security research to the level of practically applicable, proven solutions in businesses and society.

Privacy Engineering considers all privacy principles and requirements, including  anonymity and security but also purpose limitation and transparency. Privacy Engineering explicitly goes beyond foundational algorithms and cryptographic primitives and prominently addresses factors such as technical system environments, organizational embedding, actual legal/regulatory givens and corresponding questions of legal/regulatory compliance, and human factors when designing novel or assessing existing privacy mechanisms for real-world use cases.

In our Privacy Engineering research, we consciously go the extra mile towards actual applicability in real-world, enterprise-grade distributed software systems and take respective challenges into account as equally relevant research subjects. This particularly includes the experimental assessment of nonfunctional properties of privacy and security mechanisms (performance impacts, scalability, load-specific effects, …), thereby fostering evidence-based trade-offs – for instance between security and performance or between anonymity level and remaining data utility.

Together with further consideration of other  non-functional properties such as (re-) usability in relevant real-world software systems contexts, coherent integration into established software stacks, architectures and development practices, or developer-friendliness, this allows us to make path-breaking contributions to the field of Privacy Engineering or, as others denote it, Privacy by Design (PbD). In particular, we develop paradigmatically novel approaches with dedicated practical relevance in areas such as novel access control schemes and mechanisms, transparency and accountability technologies, or the quality- and performance-aware provision of anonymity guarantees. 

Our concepts (and the respective prototypes) are specifically tailored to and proven to be applicable in industry-grade distributed software systems and architectures. We thereby significantly advance the state of the art in Privacy Engineering, allowing industry to better materialize privacy requirements in real-world technologies. We educate the next-generation of Privacy Engineers, a specialization and skill that has been denoted the “superheroes” discipline within the privacy profession.
