Its applicability to the health domain was 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 a trust- and consent-based approach to the secure authentication and digital contract negotiation central to this endeavor and discusses the challenges that arose during the adoption of the Gaia-X framework, particularly 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 the digital sovereignty of both citizens and corporations, as well as its realization via future Internet technologies.<\/jats:p>","DOI":"10.3390\/fi16120463","type":"journal-article","created":{"date-parts":[[2024,12,9]],"date-time":"2024-12-09T10:11:47Z","timestamp":1733739107000},"page":"463","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Gaia-X-Med: Experiences with Building Dataspaces for Medical Applications"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1037-3404","authenticated-orcid":false,"given":"Bennet","family":"Gerlach","sequence":"first","affiliation":[{"name":"Institute of Telematics, University of L\u00fcbeck, 23562 L\u00fcbeck, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3707-3307","authenticated-orcid":false,"given":"Hannes","family":"Hesse","sequence":"additional","affiliation":[{"name":"Unitransferklinik L\u00fcbeck, 23562 L\u00fcbeck, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1292-8925","authenticated-orcid":false,"given":"Stefan","family":"Fischer","sequence":"additional","affiliation":[{"name":"Institute of Telematics, University of L\u00fcbeck, 23562 L\u00fcbeck, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3696-9222","authenticated-orcid":false,"given":"Martin","family":"Leucker","sequence":"additional","affiliation":[{"name":"Unitransferklinik L\u00fcbeck, 23562 L\u00fcbeck, Germany"},{"name":"Institute of Software Engineering and Programming Languages, University of L\u00fcbeck, 23562 L\u00fcbeck, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,9]]},"reference":[{"key":"ref_1","unstructured":"Lohm\u00f6ller, J., Pennekamp, J., Matzutt, R., and Wehrle, K.
