DescriptionDifferential privacy (DP) techniques are being widely applied to protect personal data. However, it remains unclear whether users will understand and trust DP and its different models. The current work evaluated users’ feedback of proposed illustrations of three DP models. We conducted an online survey study with 30 participants and an in-depth interview study with an additional six participants. Based on the survey and the interview results, we identified factors in the illustrations that interfered with participants’ comprehension of each model. Based on the findings, we discuss potential improvements to enhance the communication of each model.
