Transparency of Privacy Risks Using PIA Visualizations

• Privacy enhancing technologies allow the minimization of risks to online data. However, the transparency of the minimization process is not so clear to all types of end users. Privacy Impact Assessments (PIAs) is a standardized tool that identifies and assesses privacy risks associated with the use of a system. In this work, we used the results of the PIA conducted in our use case to visualize privacy risks to end users in the form of User Interface (UI) mock ups. We tested and evaluated the UI mock-ups via walkthroughs to investigate users' interests by observing their clicking behavior, followed by four focus group workshops. There were 13 participants (two expert groups and two lay user groups) in total. Results reveal general interests in the transparency provided by showing the risks reductions. Generally, although participants appreciate the concept of having detailed information provided about risk reductions and the type of risks, the visualization and usability of the PIA UIs require future development. Specifically, it should be tailored to the target group's mental models and background knowledge.
