Digitising personal information is changing our ways of identifying persons and managing relations. What used to be a "natural" identity, is now as virtual as a user account at a web portal, an email address, or a mobile phone number. It is subject to diverse forms of identity management in business, administration, and among citizens. Core question and source of conflict is who owns how much identity information of whom and who needs to place trust into which identity information to allow access to resources.

This book presents multidisciplinary answers from research, government, and industry. Research from states with different cultures on the identification of citizens and ID cards is combined towards analysis of HighTechIDs and Virtual Identities, considering privacy, mobility, profiling, forensics, and identity related crime.

The introduction of Enterprise Identity Management Systems (EIdMS) in organizations even beyond the purely technological level is a costly and challenging endeavor. However, for decision makers it seems difficult to fully understand the impacts and opportunities arising from the introduction of EIdMS. This book explores the relevant aspects for an ex-ante evaluation of EIdMS. Therefore it examines this domain by employing a qualitative expert interview study to better understand the nature of EIdMS, as they are situated between security and productive IT systems. To this regard, the focus is put on the general nature of EIdMS projects and the constructs being relevant for analyzing such projects in the decision support phase. Based on the derived constructs and thematic topics from the interviews, an explanatory model for EIdMS introductions is derived and iteratively improved and evaluated. Finally, a possible application use-case for the creation of adequate decision support tools is presented.
