Abstract
The European Union (EU) Digital Identity Wallet (DIW) intends to give citizens control over personal data sharing. The DIW users will have full and sole control over their data. The EU intends to address the risk to citizens' privacy in cases where data from and about users is gathered and exchanged by online service providers. However, it is unclear how users of the EU DIW can decide what data to share and how to prevent sharing too much data with online service providers. In order to reduce this risk, we need to understand it first. Drawing on expert interviews, this paper presents a novel analysis of the risk of over sharing through the EU DIW. It defines the risk and what aspects influence the risk from literature, documentation and expert interviews. Over-sharing data occurs when users share more data than strictly required for the service or product acquired online and multiple aspects influence this risk, specifically the user capabilities and orientation, the loss of context awareness, the quality of the data and the ease of sharing.
