Service Oriented Federated Identity System Framework

The rapid evolution of network and distributed computing, such as Service Oriented Architecture (SOA), is increasing the challenge of securely controlling access to enterprise IT resources. As gaining access to distributed resources becomes increasingly vital, the ability to make sure that the right people have secure access to the right information at the right time becomes a critical requirement. Leading enterprises have deployed identity federation to be closer to partners, accelerate execution of business partnerships, cut cost and complexity of integrating outsourced services. This paper discusses the requirements of federated identity system. A Services Oriented Federated Identity System Framework is proposed, which emphasizes flexible identity management and dynamic discovery. Furthermore, How to use ontology to describe the semantics of identity information is discussed. .
