A bidirectional privacy control that hides the advertiser from the traffic source and the traffic source from the advertiser.
Blind Routing is a data-isolation model for a lead network with two external parties. Traffic providers must not learn which advertiser (brand) their leads ultimately reached, and advertisers must not learn who generated the traffic — each side sees only its own half of the transaction.
It is enforced at the data-serialization boundary rather than in the interface, so the scrub applies to every surface a restricted party can reach: API responses, exports and self-service portals alike. Fields revealing the source (provider id, click/sub ids, IP, device) are stripped for advertisers; fields revealing the destination (brand, autologin/partner endpoints) are stripped for providers.
Combined with role-based data scoping, a provider or advertiser account cannot even address a record outside its own scope.
