A claim is a piece of information about a particular subject. It can be anything that the subject is owned by or associated with, such as name, group, preferences, etc. A claim provides a single and general notion to define the identity information related to the subject. Claim-based identity is a common way for any application to acquire the identity information. It provides a consistent approach for all applications by hiding the lower level implementation. Claims are also used in identity propagation, by packaging the claims into one or more tokens (such as SAML). These tokens are then issued by an issuer; commonly known as a security token service (STS).
The Claim Management component of WSO2 Carbon allows you to map a set of attributes from the underlying user store to a set of defined claims. The underlying user store can be either the external user store or the internal user store.
A set of claims is identified as a dialect. Different dialects represent the same piece of information with different claim URIs.
