  • Achieving Privacy in a Federated Identity Management System

    Achieving Privacy in a Federated Identity Management System

    Achieving Privacy in a Federated Identity Management System Susan Landau1, Hubert Le Van Gong1, Robin Wilton2 {[email protected], [email protected], [email protected]} 1 Sun Microsystems 2 Future Identity Abstract. Federated identity management allows a user to efficiently authenticate and use identity information from data distributed across multiple domains. The sharing of data across domains blurs security boundaries and potentially creates privacy risks. We examine privacy risks and fundamental privacy protections of federated identity-management systems. The protections include minimal disclosure and providing PII only on a “need-to-know” basis. We then look at the Liberty Alliance system and analyze previous privacy critiques of that system. We show how law and policy provide privacy protections in federated identity- management systems, and that privacy threats are best handled using a combination of technology and law/policy tools. Keywords: federated identity management, privacy, law, policy. 1 Introduction In solving one problem, federated identity management raises others. For in- stance, federated identity management can simplify a user’s experience through the use of single sign on (SSO) at multiple websites, thus enabling multiple ser- vices to be accessed as a unified whole and simplifying the complex process of managing user accounts after systems merge [16, pp. 16-17]. But by enabling the dynamic use of distributed identity information, federated identity manage- ment systems blur the divide between security domains, apparently creating a potential risk to privacy. We believe that separating the different contexts of a user’s identity through federation creates privacy in depth and can substantially enhance user privacy.
