Privacy and Threat in Practice: Mobile Messaging by Low-Income New Yorkers
Ame Elliot, Simply Secure
Is a theoretically-secure system any good if it doesn’t address users’ real-world threat models? Is the security community today meeting the needs of a mass, global audience, or simply building tools and features for itself? Do we know how to understand what people really need?
We asked a group of straight-talking New Yorkers about the data-security threats they face. Their answers indicate a significant gap between their lived experience and the way our community thinks about security. To bridge this gap and get privacy-preserving systems into the hands of real people, we need more foundational research to understand user needs, not only late-stage usability studies in a lab.
Through in-context interviews in homes, restaurants, and libraries, our study gained insights into a world of constant surveillance experienced by a group of low-income African-Americans. They shared specific examples of how their phone is threatened at home, work, and on the street. This talk shares our participants’ threat models. From shoulder-surfing, to catfishing, to how a "renter’s mindset" develops around handsets controlled by adversarial telecom providers, understanding privacy and threat in practice has far-reaching implications for the future of information security.
