National electronic identity (e-ID) card schemes and electronic identity management systems (e-IDMS) in Europe are characterised by considerable diversity. This contribution analyses the creation of a national e-IDMS in Austria with the aim of improving our understanding of the reasons behind the genesis of particular designs of national e-IDMS. It seeks to explain how the system’s specific design evolved and which factors shaped its appearance. Being part of a comparative four country study, a common theoretical framework is employed to allow (...) for a comparison of national e-IDMS in Austria, Belgium, Germany and Spain. It combines the approach of actor-centred institutionalism and the concept of path dependence in order to analyse the innovation process and to explain resulting key characteristics of the e-IDMS in Austria: a technology-neutral system with multiple tokens; an ID model based on the Central Register of Residents; a privacy concept using sector-specific personal identifiers. It is shown that innovation process and outcome are not only shaped by specific actor constellations dominated by strategic e-government bodies, but also by path dependence at three levels: technological, institutional and organisational.
