An Online Experiment of Privacy Authorization Dialogues for Social Applications
Na Wang

Abstract:
Several studies have documented the constantly evolving
privacy practices of social networking sites and users'
misunderstandings about them. Researchers have criticized
the interfaces to "configure" privacy preferences as opaque,
uninformative, and ineffective. The same problems have
also plagued the constant growth of third-party applications
and their troubling privacy authorization dialogues. In this
paper, we report the results of an experimental study
examining the limitations of current privacy authorization
dialogues on Facebook as well as four new designs which
we developed based on the Fair Information Practice
Principles (FIPPs). Through an online experiment with 250
users, we study and document the effectiveness of
installation-time configuration and awareness-enhancing
interface changes.
