Entangled: A Case Study of Data Exchange and Actor Relationships in a Mobility Ecosystem

With the continuous proliferation of digital services, personal data sharing has become an ever-pressing issue. Contemporary solutions such as identity management raise privacy questions for customers, as the interoperability between different service providers requires substantial integration efforts. Self-sovereign identity (SSI) is a novel identity management approach leveraging digital credentials and promising to provide privacy-friendly data sharing to users and enable interconnected ecosystems based on a common infrastructure. While creating governance frameworks has been identified as a major challenge in implementing SSI, the scarce research on this subject mainly focuses on the technical subsystem. This paper presents a case study of an urban mobility ecosystem showcasing relevant governance aspects based on data exchange, actor relationships, and service offerings.
