Abstract: Electronic Identity Management has become a key ingredient for electronic governance. Countries around the world are using state-of-the-art technologies to digitize their citizen service delivery process. Uniquely identifying citizens and electronically managing their authentication information is a must for trust and fairness. However, at the implementation level, various modes of electronic identity management are currently in practice, primarily: centralized, user-centric, and federated models. This paper presents an overall summary of the level and type of identity management strategies adopted by different governments. We believe, this information will be valuable to the policymakers and development strategies to plan, design, implement and update the current state of the art.
