This course will focus on how human factors, such as human behavior, goals, and needs, both shape

and are shaped by, the security and privacy of digital systems. For instance, how human behavior

can lead to insecure systems and how digital systems can threaten users’ safety. We will explore

various topics in usable security and privacy and digital safety such as authentication, mental

models of encryption, scams, online hate and harassment, and technology-facilitated interpersonal

abuse. We will learn and apply human-centered and empirical research methods in the context of

these topics, and discuss best practices of human-centered and empirical research in computer security.
