User-centered security and privacy

Abstract

Abstract:

As technology becomes more pervasive, it amplifies existing or creates new security and privacy risks for end users. To mitigate these risks,we need to consider both technical and human aspects of security and privacy. End-user security without usability is ineffective: Recent industry reports attribute over half of cybersecurity breaches to human factors.

The goal of my research is to improve security and privacy for end users of existing and emerging technologies. In this talk, I will discuss my approach to user-centered security and privacy. I will focus on two examples, my work on user authentication and smart homes. My work on user authentication aims to develop techniques for better (easy to use and secure) authentication methods. For example, for computing devices that require physical interactions, I developed a seamless authentication method, taking us one step closer to the seamless computing vision of Mark Weiser. My work on smart homes involves analyzing smart-home platforms and end-user mental models to identify and address security challenges related to smart devices in the context of homes as well as short-term rentals, such as Airbnbs. For both research areas, I will discuss example projects, describe key contributions, and highlight future work.
