Survey on federated identity management systems

Abstract

Federated Identity Management is a version of Single Sign-On where each device, system, and application queries a centralized database for authentication and authorization information. Federated Identity Management systems are tasked with enabling authentication and authorization data across organizational boundaries. Federated Identity Management system, authentication data can be passed across security domains from within a company to its business partners. This can enable Single Sign-On to extend past organizational boundaries. Federated Identity Management is often abbreviated FIM. © 2010 Springer-Verlag Berlin Heidelberg.
