Abstract
Web 2.0, social media, cloud computing, and IoT easily connect people around the globe, overcoming time and space barriers, and offering manifold benefits. However, the technological advances and increased user participation generate novel challenges for protecting users' privacy. From the user perspective, data disclosure depends, in part, on the perceived sensitivity of that data, and thus on a risk assessment of data disclosure. But in light of the new technological opportunities to process and combine data, it is questionable whether users are able to adequately evaluate the risks of data disclosures. As mediating authority, data protection laws try to protect user data, granting enhanced protection to 'special categories' of data. In this publication, the legal, technological, and user perspectives on data sensitivity are presented and compared. From a technological perspective,…
