Claims-based identity means to control the digital experience and to use digital resources based on things that are said by one party about another. A party can be a person, organization, government, Web site, Web service, or even a device. The very simplest example of a claim is something that a party says about itself. Claims-based identity has been possible for quite a while, but there are now tools available that make it much easier for developers of Windows-based applications to implement it. These tools include the Windows Identity Foundation (WIF) and Microsoft Active Directory® Federation Services (ADFS) v2. This book shows you when and how to use these tools in the context of some commonly occurring scenarios.
