- KonferenzbeitragBalancing Privacy and Value Creation in the Platform Economy: The Role of Transparency and Intervenability(Open Identity Summit 2023, 2023) Astfalk, Stefanie; Schunck, Christian H.Data are essential in the platform economy to create value. Since the General Data Protection Regulation (GDPR) demands a high level of protection for personal data, it becomes challenging for small- and medium-sized businesses to provide both: data-based services and compliance to the GDPR. Therefore, the paper focuses on the privacy protection goals of transparency and intervenability to enable privacy friendly business models. To better understand how this approach supports the needs of small- and medium-sized platform providers, a qualitative interview study is conducted. Especially, the lack of legal certainty and the unclarity of how the GDPR can be implemented compliantly in practical terms is found to be a challenge. Based on the interviews, requirements are derived which a personal rights management tool enabling transparency and intervenability should fulfill such as supporting legal compliance or reducing operational complexity. In summary, small- and medium-sized platform providers see providing transparency and intervenability as a promising new approach which they are willing to deploy given the right personal rights management tool.

- KonferenzbeitragTracking or being tracked: How much do self-trackers care about their data’s privacy?(Sicherheit 2024, 2024) Floris, Alice; Astfalk, Stefanie; Sellung, Rachelle; Roßnagel, HeikoThe advancement of tracking technology has given people new ways to understand and rediscover themselves. These technologies provide new and unique challenges to individual privacy, particularly when privacy breaches become less apparent, and users are not adequately aware of privacy regulations and risks. Nonetheless, research on privacy concerns with self-tracking data remains inconclusive and poorly understood. Moreover, the fundamental concept of data self determination — the cornerstone of information privacy — is under attack as users fail to take the necessary precautions to protect themselves. The current study used a quantitative method to examine the overall profile of self-trackers as well as their attitudes, preferences, concerns, and hurdles to (better) privacy protection. Self-trackers, according to the findings, seek control over both their bodies (i.e., self-optimization) and their data. Additionally, people just expect to have full control over their data and are disinterested in enforcing it or devoting effort to it. This suggests that, while privacy is still associated with control, users' actions and decisions make them more susceptible to loss of data control. We contend that these findings are consistent with the privacy paradox as well as the failure of privacy self-management, as defined by [So13].
