2. BackGround Check Model

The background-check model is so named because of the resemblance of how employers and volunteer organizations perform background checks. In this model, the attestation sequence is initiated by a Relying Party. The Attestor conveys Evidence to the Relying Party. Upon receiving evidence the Relying Party initiates a session with the Verifier. Once session is established, it forwards the received Evidence to the Verfier. The Verifier, compares the received Evidence to its appraisal policy for evidence and returns an Attestation Result to the Relying Party. The Relying Party then compares the

two step procedure. In the first step, an Attester conveys Evidence to a Verifier which compares the Evidence against its appraisal policy. The Verifier
then gives back an Attestation Result to the Attester, which simply caches it. In the second step, the Attester presents the Attestation Result (and possibly additional Claims/evidence) to a Relying Party, which then compares this information against its own appraisal policy to establish the trustworthiness of the attestor.

In this model, the attestation sequence is initiated by a Relying Party. The Attester conveys Evidence to the Relying Party, which does not process its payload, but realys the message and optionally check its signature against a policed trust anchor store. Upon receiving the evidence the Relying Party initiates a session with the Verifier. Once session is established, it forwards the received Evidence to the Verfier. The Verifier, appraises the received Evidence according to its appraisal policy for Evidence and returns a corresponding Attestation Result to the Relying Party. The Relying Party then checks the Attestation Result against its own appraisal policy to conclude attestation.
