Summary:
Human participation in cybersecurity and privacy research is essential to finding solutions to reducing cyber-attacks and minimizing the risk of personal private information breaches. However, many users are unwilling to participate in cybersecurity research because they do not understand how their identity is protected. Even though differential privacy (DP) techniques have been proposed and applied to protect personal data, it remains unclear whether users understand DP. In this exploratory study, we used an online questionnaire to compare the effectiveness of two DP communication approaches: analogical reasoning with visualization (ARV) and a text-only description (TOD), in enhancing the understanding of privacy-utility trade-offs of DP and the willingness of participants to share their private health information for cybersecurity research. We found significant differences in understanding DP between participants exposed to the ARV and TOD. The participants exposed to the TOD condition had a better understanding of DP. We found no significant differences in the willingness to share private information. Understanding DP was not correlated to the willingness to share private information. More research work is required to develop and test analogical reasoning approaches to communicating DP to specific end-users to increase their understanding and willingness to share their private information for research.
