An Attribute-Oriented Model for Identity Management

Secure, interoperable and flexible identity management (IdM) architecture should be designed in large organizations to alleviate ¿identity confusion¿. Existing network-centric, service-centric and user-centric IdM models are not always efficient during processing and communicating. In this paper, we propose an attribute-oriented IdM model, which adaptively and efficiently considering requirement similarity degree of attributes in identity management. This approach is the first time to balance the requirement from network, service, user and other aspect. We elaborate the design approach of attribute-oriented module and implement it in a digital library case to show its effectiveness.
