A system, comprising: an anonymized profile identifier datastore configured to store at least one anonymized profile identifier, provider's profile identifier, and profile consumer's profile identifier; a permissions profile datastore configured to store permissions profile information for at least one user identified by the at least one anonymized profile identifier; at least one permitted use gatekeeper application (126-1, 126-2) operatively coupled to at least one provider system and a privacy services application; a server device configured to execute the privacy services application, wherein the privacy services application is operatively coupled to at least one profile consumer system, the at least one provider system (110, 170), the anonymized profile identifier datastore, and the permission profile datastore, the privacy services application is configured to: receive a federated search request from a profile consumer system of the at least one profile consumer systems to which the privacy services application is operatively coupled, the profile consumer system being identified by a profile consumer identifier, and the federated search request including a profile search criteria, transmit a profile search request to the at least one permitted use gatekeeper application (126-1, 126-2), the profile search request including the profile search criteria, receive a profile search response from the at least one permitted use gatekeeper application (126-1, 126-2), the profile search response including a search result list of users, combine each of the search result lists of users received in the profile search response from the at least one permitted use gatekeeper application (126-1, 126-2) into a combined search result list of users, and translate the combined search result list of users that is identified by the provider's profile identifiers to a combined search result list of profile consumer's profile identifiers that is recognizable by the profile consumer system. an anonymized profile identifier datastore configured to store at least one anonymized profile identifier, provider's profile identifier, and profile consumer's profile identifier;
