User-Centered Privacy to Improve User Quantification using Smartphone Sensing
MobileHCI 2023, Sept. 26 - 29, 2023, Athens, Greece (bib)

Mobile sensing technologies enable adaptive and context-aware applications. At the same time, they raise a range of privacy concerns. Thus, to reduce privacy concerns today apps are restricted from accessing certain information hindering to deliver full personalization and novel adaptive use cases. I investigate this issue by shedding light on the privacy concerns that arise from state-of-the-art mobile sensing data, studying the usersâ perspective on mobile smartphone privacy, and proposing concepts that protect the usersâ privacy while keeping the resulting data usable. I found that there is a lack of user-centered privacy design and that control features play a key role to give the users more agency. My results motivate the proliferation of control-enhancing privacy features in mobile applications. I show that the benefits of trust and system adoption surpass any impairments that control features might bring to the data.
