Claim

Definition: An assertion made by a Claimant of the value or values of one or more Identity Attributes of a Digital Subject, typically an assertion which is disputed or in doubt. [KimC, BenL, PeterD, ScottC, PaulT]

Examples of the kinds of Identity Attributes that might be conveyed in a Claim:


 * 1) A Claim could just convey an identifier—for example, that the digital subject's student number is 490-525, or that the digital subject's Windows name is REDMONDkcameron. This is the way many existing identity systems work.
 * 2) Another Claim might assert that a Digital Subject knows a given key—and should be able to demonstrate this fact.
 * 3) A set of Claims might convey personally identifying information—name, address, date of birth and citizenship, for example.
 * 4) A claim might simply propose that a Digital Subject is part of a certain group—for example, that she has an age less than 16.
 * 5) And a Claim might state that a Digital Subject has a certain capability—for example, to place orders up to a certain limit, or modify a given file.

Comment1: Claims may or may not be directed to specific Parties. [KimC, DickH, PaulT]

Comment2: A Claim is an association between a Claimant, a Digital Subject, and an Identity Attribute [PaulT]
