App-Stores, zu regulieren. In vielen F\u00e4llen zwingen Gatekeeper ihren Gesch\u00e4ftskunden (den Dienstanbietern) die Integration eigener Plattform-Identit\u00e4tsdienste in ihren Diensten und Anwendungen auf. So ben\u00f6tigen die Endnutzer der Dienstanbieter digitale Identit\u00e4ten, die durch Plattform-Identit\u00e4tsdienste bereitgestellt und verwaltet werden m\u00fcssen, um auf die angebotenen Anwendungen der Dienstanbieter zugreifen zu k\u00f6nnen. Der Digital Market Act sieht vor, dass Plattformanbieter ihre Gesch\u00e4ftskunden nicht dazu zwingen d\u00fcrfen, plattformspezifische Identit\u00e4tsdienste in die Anwendungen und Dienste der Gesch\u00e4ftskunden zu integrieren. Zwar k\u00f6nnen nach dem Digital Markets Act Dienstanbieter die Identit\u00e4tsdienste frei w\u00e4hlen, aber die Endnutzer sind weiterhin dazu gezwungen, die von den Dienstanbietern angebotenen Identit\u00e4tsdienste zu verwenden. Das neue Paradigma der selbstsouver\u00e4nen Identit\u00e4ten (Self-sovereign identity, SSI) verspricht Endnutzern unabh\u00e4ngig von Identit\u00e4tsdiensten Kontrolle und Hoheit \u00fcber ihre digitalen Identit\u00e4ten. Die Zahl der Dienste und Anwendungen, welche das SSI-Paradigma umsetzen, nimmt rapide zu. Zugrundeliegende Standards und Protokolle unterscheiden sich jedoch teils signifikant. Aufgrund dieser Divergenz ist das Sicherstellen der Interoperabilit\u00e4t unterschiedlicher Dienste und Anwendungen, die das SSI-Paradigma umsetzen, einer der gr\u00f6\u00dften Herausforderungen, um eine breite Nutzerakzeptanz zu erreichen. In diesem Artikel diskutieren wir die Herausforderungen der Interoperabilit\u00e4t im Detail, bieten einen systematischen Ansatz zu ihrer Beseitigung und zeigen ein praktisches Beispiel auf nationaler Ebene in Deutschland.<\/jats:p>","DOI":"10.1365\/s40702-023-00947-3","type":"journal-article","created":{"date-parts":[[2023,2,28]],"date-time":"2023-02-28T18:03:14Z","timestamp":1677607394000},"page":"405-421","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Interoperable Selbstsouver\u00e4ne Identit\u00e4ten: Ein Digital Markets Act f\u00fcr Endnutzer?","Interoperable Self-sovereign Identities: Digital Markets Acts for End Users"],"prefix":"10.1365","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2044-0826","authenticated-orcid":false,"given":"Hakan","family":"Yildiz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3785-3130","authenticated-orcid":false,"given":"Artur","family":"Philipp","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3115-0071","authenticated-orcid":false,"given":"Aljoscha","family":"Schulte","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4356-5613","authenticated-orcid":false,"given":"Axel","family":"K\u00fcpper","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0402-4379","authenticated-orcid":false,"given":"Sebastian","family":"G\u00f6ndor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6921-294X","authenticated-orcid":false,"given":"Sandro","family":"Rodriguez Garzon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"93","published-online":{"date-parts":[[2023,2,28]]},"reference":[{"key":"947_CR2","unstructured":"Allen C (2016) The path to self-sovereign identity. http:\/\/www.lifewithalacrity.com\/2016\/04\/the-path-to-self-soverereign-identity.html.
