Hi. I am Jaap-Henk Hoepman.

Because we have become increasingly dependent on information technology, I believe it is important that that we, users individually as well as society as a whole, remain in control. This means we must do all that is necessary to ensure that the technology is open, transparent, reliable, trustable, secure and aligned with our digital liberties. I think different professionals (engineers, legal scholars, social scientists and even artists) can learn from each other's approaches and results. We should join forces to shape our future in this new world.

I am a guest professor at the PRISEC - Privacy And Security group of Karlstad University, Sweden.

I am an associate professor in privacy enhancing protocols and privacy by design at the Digital Security group of the Institute for Computing and Information Sciences of the Radboud University Nijmegen, the Netherlands. I am a principal scientist of the Privacy & Identity Lab, and member of iHub, Radboud University’s interdisciplinary research hub on Digitalization and Society.

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.

My research is inspired by practical problems. I study privacy by design, and privacy friendly protocols for identity management and the  Internet of Things. I enjoy talking about my research, and speaking about it in public to a general audience. That is also one of the main reasons to maintain this blog.

In my free time I enjoy making my own music, designing visuals, and practice Okinawan Goju Ryu karate-do.

This blog expresses personal views and does not express the views of my employer(s).

About XOT

Sometimes people wonder why my blog is hosted on the domain xot.nl (and why my Twitter handle is @xotoxot).

XOT stands for the three symbols you see (from top to bottom) on the main page of my website. These symbols stand for "head", "belly", "bottom" respectively. And from that everything else follows.

As for my Twitter handle... @xot was already taken (but is not used at all...)


I enjoy talking about information technology, explaining it to laypersons, and to show how technology can both severely damage our privacy as well as protect our privacy (when properly designed). Please contact me or see my speakers profile (in Dutch).
