All identity data is kept securely in the user's SSI wallet, ensuring that it is exclusively accessible by the individual.predominant cloud service provider, nor is the establishment of a central Gaia-X Identity provider necessary. Users are thus completely independent of third parties and decide themselves which identity data they share with whom, as all identity data is securely stored only with the individual user in their SSI wallet.
