Abstract:
As the past has shown, many providers of social media services consistently demonstrate an insufficient commitment to user privacy. This has led to an increase in users’ privacy concerns. Several privacy-preserving alternatives were proposed in the research community and the market. However, these platforms face the challenges of proving and demonstrating that users’ privacy concerns are addressed within their scope as well as gaining users’ trust. In this work, we mitigate privacy concerns and enhance the trustworthiness of privacy-preserving social media, in particular a hybrid social media application. For that, we develop trust-related software features elicited with the TrustSoFt method. We evaluate the impact of the specified features on the privacy concerns as well as on the trustworthiness of the examined application by conducting an extensive user study. Furthermore, we analyze the relationships between information privacy concerns, trusting beliefs, risk beliefs, and willin
gness to use in the context of hybrid social media. Results reveal the special importance of addressing particular concerns, such as “Awareness of Privacy Practices”.
