The aim of the IDunion organisation is to create an open ecosystem for decentralised identity management, which can be used worldwide and is oriented towards European values and regulations. Everyone (including natural as well as legal persons and things) has the possibility to manage their identity information themselves and to decide when they want to share it with whom. The sovereignty over one's own data is important, especially when it comes to very sensitive and personal information. Users can choose one of several wallets, which are used to store credentials and present them to third parties as required. This is useful for a wide range of use-cases and enables a new way of identity management. This is no longer done by technology companies acting as a central identity manager, but by the user himself! The user can decide where the information is to be viewed, with which program it is managed and with whom information is shared. We call this concept the self-sovereign identity.
