  Organizations started to adopt differential privacy (DP) techniques hoping to
persuade more users to share personal data with them. However, many users do
not understand DP techniques, thus may not be willing to share. Previous
research suggested that the design of DP mechanism communication could
influence users' willingness to share data. Based on the prior work, we propose
a new communication pipeline that starts by asking users about their privacy
concerns and then provides a customized DP mechanism and communication. We also
propose a design framework that systemically explores effective communication
designs ranging from a text-based high-level description to a step-by-step
interactive storyboard. Based on the framework, we created 17 designs and
recruited five people to evaluate. Our user study showed that text-based
descriptions have the highest clarity in all scenarios, while the step-by-step
interactive storyboards have the potential to persuade users to trust central
DP. Our future work will optimize the design and conduct a large-scale efficacy
study.
