When a subject claims an identity, what process is being performed?

When a subject claims an identity, the process being performed is identification. Identification involves a user or system asserting their identity by providing a username, email address, or other identifiers to indicate who they are. This is the initial step in the identity and access management process.

Once identification occurs, further steps typically follow, such as authentication, where the claimed identity is verified through credentials like passwords or biometrics. It's important to understand that identification is about claiming an identity, while authentication confirms that claim.

While the other processes like verification, which entails confirming the claimed identity, and authorization, which involves granting permissions based on the authenticated identity, are critical in the broader context of identity and access management, they do not specifically refer to the act of claiming an identity itself. Hence, the focus on the subject claiming an identity correctly aligns with the identification process.
