SourceID.org |Liberty Alliance: "SAML, Liberty Alliance, WS-Federation - Identity Infrastructure
Federated identity infrastructure enables cross-boundary single sign-on, dynamic user provisioning and identity attribute sharing. By providing for identity portability, identity federation affords end-users with increased simplicity and control over the movement of personal identity information while simultaneously enabling companies to extend their security perimeter to trusted partners. New identity federation standards provide companies with the foundation for securing their outsourced business processes, hosted applications and web services while simultaneously addressing a host of other security, management and integration challenges."
