Abstract: Healthcare data should be linked and aggregated across data sources from different organisations to manage performance and provide integrated services. The internet offers the possibility of providing near real-time integration, but the central issue is how to integrate federated identity management with healthcare data integration to protect patient identity and ensure compliance with privacy legislation. In this paper, we use a healthcare scenario to analyse three proposed approaches. Each approach addresses some aspects of the problem while failing to address others. We then present a single framework that combines the three approaches into a single, more comprehensive approach.
