IUA Access Token

Provided an ITI-71 results in a PERMIT access token issued. That token would have the following residual element to inform the Consent Enforcement Point that it needs to restrict the results.

Given that the token will express the permit portion, the residual would need to express the refinement. In this case the oAuth token and scope will address a general permit, and thus the residual need only express the forbid to information related to the encounter.

The token would need to include an ihe_pcf extension to point at this consent, and that would include a residual to express the refinement. Shown as followed:

• The restriction to the given purpose (Treatment, Payment, and Operations) would be expressed in the ihe_iua extension
  • The other ihe_iua extension parameters are not shown below
• The restriction to forbid data related to the given encounter
