Windows Identity Foundation for Windows 7 and Windows Server 2008 R2 (64-bit) build claims-aware applications that externalize user authentication from the application, improving developer productivity, enhancing application security, and enabling interoperability. Developers can enjoy greater productivity, using a single simplified identity model based on claims. They can create more secure applications with a single user access model, reducing custom implementations and enabling end users to securely access applications via on-premises software as well as cloud services. Finally, they can enjoy greater flexibility in application development through built-in interoperability that allows users, applications, systems and other resources to communicate via claims.
