The project started in 2012 and involved 55 organizations, both public and private, across 19 European countries. It has further built on the STORK framework for cross-border electronic identification and authentication (eID) of citizens and businesses in the EU and Associated Countries. STORK 2.0 allows citizens to identify themselves across-borders by using identity-related data from authentic and reliable sources (attribute providers) or to represent other natural or legal persons, in the context of different business domains.
