Recently, identity management has gained increasing attention from both enterprises and government organisations, in terms of security, privacy, and trust. A considerable number of theories and techniques have been developed to deal with identity management issues within and between organisations. In this paper, the authors reviewed, assessed, and consolidated the research and development activities of identity management in 14 privately and publicly funded organisations. Furthermore, the authors developed a taxonomy to characterise and classify these identity management frameworks into two categories: processes and technologies. The authors then studied these frameworks by systematically reviewing the whole lifecycle of an identity management framework, including actors, roles, security, privacy, trust, interoperability, and federation. This paper aims to provide the reader with the state of art of existing identity management frameworks and a good understanding of the research issues and progress in this area.
