Title: Security Indicator Design in Web Browsers

Abstract

In this study, we aim at providing conceptual and empirical insights
to the design of security indicators in web browsers. Using a survey
study, we explore the needs and concerns of users, resulting in a set
of design considerations for better Extended Validation (EV)
certificate indicator design. Drawing on the affordance theory, we
propose affordance-based principles for the design of web
authentication indicators. Following these principles, we present a
new design for EV certificate interface in the Firefox browser. We
then conduct a qualitative study to evaluate three different versions
of EV indicators. Our findings offer some implications for the design
of more effective web authentication indicators in web browsers.
