Prof. Dr.-Ing. Volker Roth
I am a professor for computer science
at Freie Universität
Berlin where I head
the Secure Identity
Research Group since 2009.
Before, I was a senior researcher at a research lab in Palo Alto
(FXPAL, now defunct), a visiting professor at
the Peter Kiewit Institute of the
University of Nebraska at Omaha, the CTO of a tech company in Omaha (OGM
Laboratories, now defunct), a senior researcher and deputy department
head at Fraunhofer
Gesellschaft in Germany, and a postdoc
at ICSI in Berkeley. I
received my "Dr.-Ing." (approx. Ph.D.) and my "Dipl.-Inform."
(approx. M.Sc.) in computer science
from Technische Hochschule
My primary occupation
on privacy and information systems security, with a particular interest
in the psychological acceptability of security mechanisms. I am
particularly excited by security mechanism designs that are as simple as
possible (but not simpler) and work without the need for a common root
