My name is Jaap-Henk Hoepman. I am an associate professor of privacy enhancing protocols and privacy by design in the Digital Security group at the Institute for Computing and Information Sciences of the Radboud University Nijmegen and principal scientist of the Privacy & Identity Lab. I am also an associate professor in the IT Law section of the Transboundary Legal Studies department of the Faculty of Law of the University of Groningen.

Moreover, I am a researcher in the Tilburg Institute for Law, Technology, and Society (TILT) at Tilburg University since February 2018 (until July 2019).

My main research interest are privacy by design and privacy friendly protocols for identity management and the Internet of Things.



I wrote a testimonial in support of XS4ALL.

The 4th Interdisciplinary Summerschool on Privacy (ISP 2019) will be held September 1-6, 2019, Hotel Erica, Berg en Dal, The Netherlands. Theme: "Dark Patterns". More info soon!

In celebration of the GDPR coming into force on May 25 2018, I released a little blue book on privacy design strategies (and a separate version in Dutch as well).


I actively maintain a blog discussing security, privacy and the societal impact of new technologies.

Starting March 2017 my blog is archived by the Dutch Royal Library.


Seeds are raw, unfinished, or simply far fetched ideas for which I do not have the time or the courage to develop them further. Personal favourite: 0906-SORRY. Also see Improved iPhone calendar. Feel free to browse them and get inspired. But tell me if you worked on them!

Web design inspired by the warchalking symbols designed by Matt Jones.
