Systems and methods for candidacy determinations and request processing while maintaining user data anonymity

A method performed by a candidacy determination system, the method comprising:

• receiving, from a first data source, anonymized first external data of a user including a first identifier;
• receiving, from a second data source, anonymized second external data of the user including a second identifier;
• receiving, from an identity resolution system having respectively received each of the first identifier and the second identifier in association with matching identifying information of the user from the first data source and the second data source, a key that associates the first identifier, the second identifier, and a common identifier with the user without providing an identity of the user;
• generating, using the association of the first identifier and the second identifier provided by the key, consolidated external data for the user that (i) includes the anonymized first external data and the anonymized second external data and (ii) is associated with the common identifier;
• providing, to the identity resolution system, non-anonymized third internal data of the user that includes at least a portion of the identifying information of the user known by the identity resolution system, wherein the identity resolution system uses the portion of the identifying information of the user to identify the common identifier for the user;
• receiving, from the identity resolution system, an anonymized dataset including the third internal data and the common identifier but excluding the portion of the identifying information of the user;
• generating, using the association of the consolidated external data with the common identifier and the common identifier included in the anonymized dataset, aggregated data that includes the consolidated external data and the third internal data from the anonymized dataset;
• and
• determining the user is a candidate for an offer set based on the aggregated data.

A method for providing identity resolution, the method comprising:

• receiving, from a first data source, identifying information of a user associated with a first identifier;
• receiving, from a second data source, the identifying information of the user associated with a second identifier;
• determining the first identifier and the second identifier are associated with the user based on a match of the identifying information of the user;
• generating a key associating the first identifier, the second identifier, and a common identifier for the user;
• providing the key to a candidacy determination system, wherein the identifying information of the user is unobtainable from the key to preserve an anonymity of the user at the candidacy determination system, and the candidacy determination system:
• uses the association of the first identifier and the second identifier provided by the key to generate consolidated external data that (i) includes first external data associated with the first identifier received from the first data source and second external data associated with the second identifier received from the second data source, and (ii) is associated with the common identifier;
• receiving, from the candidacy determination system, non-anonymized third internal data of the user that includes at least a portion of the identifying information of the user to enable identification of the common identifier for the user;
• and
• generating and providing, to the candidacy determination system, an anonymized dataset including the third internal data and the common identifier but excluding the portion of the identifying information of the user, wherein the candidacy determination system:
• generates, using the association of the consolidated external data with the common identifier and the common identifier included in the anonymized dataset, aggregated data that includes the consolidated external data and the third internal data from the anonymized dataset, and
• processes the aggregated data to determine the user is a candidate for an offer set.
