Title

PIV Identity Account Identification

Control

The IdP SHALL issue a unique federated identifier for each PIV identity account according to the requirements in Sec. 6.2.1 , consisting of the logical combination of:

• A subject identifier for the PIV identity account that is locally unique for the account at the IdP, and

• A globally unique identifier for the IdP.

The federated identifier SHOULD be stable over time for a PIV identity account at an IdP. To protect privacy, the IdP SHOULD use an unguessable value for the subject identifier, such as the output from an approved random-number generator or a value derived from an approved derivation method for the subject. The federated identifier SHALL NOT contain any personally identifiable information or any personal identifiers, such as the cardholder UUID, in an unencrypted or reversible form.
