Engineering Personal Data Sharing

This report attempts to look closer at specific use cases relating to personal data sharing, primarily in the health sector, and discusses how specific technologies and considerations of implementation can support the meeting of specific data protection. After discussing some challenges in (personal) data sharing, this report demonstrates how to engineer specific technologies and techniques in order to enable privacy preserving data sharing. More specifically it discusses specific use cases for sharing data in the health sector, with the aim of demonstrating how data protection principles can be met through the proper use of technological solutions relying on advanced cryptographic techniques. Next it discusses data sharing that takes place as part of another process or service, where the data is processed through some secondary channel or entity before reaching its primary recipient. Lastly, it identifies challenges, considerations and possible architectural solutions on intervenability aspects (such as the right to erasure and the right to rectification when sharing data).
