Method, system, and computer program product for matching card transaction data to mobile application usage

A system, comprising:

• at least one processor;
• and
• at least one non-transitory computer readable medium including one or more instructions that, when executed by the at least one processor, cause the at least one processor to:
• generate a plurality of regions within a geographic area, each region of the plurality of regions associated with a region identifier;
• receive transaction data associated with a plurality of transactions conducted between a plurality of accounts and a plurality of merchants using a plurality of account identifiers, the transaction data comprising, for each transaction, an account identifier and a transaction location;
• receive mobile application data associated with a plurality of interactions between a plurality of mobile device users and at least one mobile application using a plurality of user identifiers, the mobile application data comprising, for each interaction, a user identifier and an interaction location;
• determine a region of the plurality of regions for each transaction of the plurality of transactions based on the transaction location;
• determine a region of the plurality of regions for each interaction of the plurality of interactions based on the interaction location;
• generate a transaction signature for each account identifier of the plurality of account identifiers based on the region for each transaction of the plurality of transactions initiated with the account identifier, resulting in a plurality of transaction signatures, each transaction signature comprising at least one region identifier in association with an account identifier used to transact in at least one region corresponding to the at least one region identifier;
• generate an interaction signature for each user identifier of the plurality of user identifiers based on the region for each interaction of the plurality of interactions associated with a corresponding user identifier, resulting in a plurality of interaction signatures, each interaction signature comprising at least one region identifier in association with a user identifier for a user interacting in at least one region corresponding to the at least one region identifier;
• match at least one transaction signature of the plurality of transaction signatures to at least one interaction signature of the plurality of interaction signatures;
• and
• link at least one account identifier of the plurality of account identifiers to at least one user identifier of the plurality of user identifiers in at least one database based on matching the at least one transaction signature to the at least one interaction signature.

• and
• link at least one account identifier of the plurality of account identifiers to at least one user identifier of the plurality of user identifiers in at least one database based on matching the at least one transaction signature to the at least one interaction signature.
