IA-04(08) Pairwise Pseudonymous Identifiers

Generate pairwise pseudonymous identifiers.



A pairwise pseudonymous identifier is an opaque unguessable subscriber identifier generated by an identity provider for use at a specific individual relying party. Generating distinct pairwise pseudonymous identifiers with no identifying information about a subscriber discourages subscriber activity tracking and profiling beyond the operational requirements established by an organization. The pairwise pseudonymous identifiers are unique to each relying party except in situations where relying parties can show a demonstrable relationship justifying an operational need for correlation, or all parties consent to being correlated in such a manner.
