Kent Seamons: "Usable Security: When Transparency Leads to Confusion and Distrust"
SECURITY SEMINAR SERIES
The quest for usable security often leads us to design systems that hide security details from users so that they can focus on their primary task. In this talk, Dr. Seamons will review some examples from our research where transparency can lead to confusion and mistakes. Users may distrust a system when they are unsure how it behaves. Researchers were surprised when a system using manual encryption was competitive with a system using automatic encryption. The users understood and trusted the system that exposed more encryption details.
