Gaia-X-Med: Experiences with Building Dataspaces for Medical Applications

Gaia-X, a European initiative, aims to create a digital sovereignty framework for service ecosystems in the future internet. Its applicability to the health domain has been explored in the Gaia-X-Med project, which aimed to establish a common dataspace for various medical use cases based on Gaia-X principles. This paper presents the approach to secure authentication and digital contract negotiation central to this endeavour and discusses the challenges that arose during adoption of the Gaia-X framework, in particular relating to the strict requirements of the European healthcare domain with regards to privacy and consent regulations. By exploring the practical implications of Gaia-X in the healthcare context, this paper aims to contribute to the ongoing discussions surrounding digital sovereignty of both citizens and corporations, as well as its realization via future internet technologies.
