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]
- 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.
- Another Claim might assert that a Digital Subject knows a given key—and should be able to demonstrate this fact.
- A set of Claims might convey personally identifying information—name, address, date of birth and citizenship, for example.
- 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.
- 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.
- Claims may or may not be directed to specific Parties. [KimC, DickH, PaulT]
- A Claim is an association between a Claimant, a Digital Subject, and an Identity Attribute [PaulT]
