Human-Centered Security

Broadly, we study the intersection of computer security and privacy with human factors. We are particularly interested in investigating end users, administrators, developers and designers of computer systems and their interdependencies with computer security and privacy mechanisms.

Our research involves large-scale analyses of the Internet and software repositories to understand the huge challenges humans face when interacting with computer security and privacy mechanisms.

To understand root causes, evaluate existing mechanisms and investigate novel ideas, we conduct all kinds of user studies with end users, administrators, and developers of these systems.

Talk: Adam Aviv on Human Factors in Mobile Authentication

We are delighted to announce that Adam Aviv will give a talk here at LUH.


Mobile authentication is a crucial component of authentication more broadly, especially as mobile devices become evermore connected to the broader computer security ecosystem. The overarching goal of my research is to improve the current state of mobile authentication by taking a holistic approach to measuring mobile authentication and its impacts that intersect directly with the user experience. In this talk, I will present a narrative of contributions to mobile authentication over the last 10 years, focusing on how human factors impact the security, from attacks, choices, and perceptions. I will particularly focus on one form of mobile authentication, Android’s graphical pattern unlock, which may be the most heavily used graphical authentication system, ever. Based on my experience, I will also present some new directions and methods that can improve the security of mobile authentication that take the user more fully into account.
