Systems and methods to match identifiers

摘要

In one aspect, a system includes a transaction handler to process transactions, a data warehouse to store transaction data recording the transactions processed at the transaction handler and to store mapping data between first user identifiers and first account identifiers, a profile generator to generate a profile of a user based on the transaction data, and a portal coupled to the transaction handler to receive a query identifying a second user identifier used by the first tracker to track online activities of a user. The system is to identify a second account identifier of the user from the second user identifier based on the mapping data between the first user identifiers and the first account identifiers to facilitate targeted advertising using the profile of the user and/or to provide information about certain transactions of the user related to a previously presented advertisement.

1. A computer-implemented method, comprising:
receiving, in a computing apparatus, first user data to track first online activities of users, the first user data identifying
first user identifiers,times of the first online activities of the first identifiers, andInternet Protocol (IP) addresses of the first online activities of the first identifiers; receiving, in the computing apparatus, second user data to track second online activities, the second user data identifying
first account identifiers configured to identify payment accounts in which payment transactions are processed via a transaction handler of a payment processing network,times of the second online activities of the first account identifiers, andInternet Protocol (IP) addresses of the second online activities of the first account identifiers; and matching, by the computing apparatus, the times of the first online activities and the Internet Protocol (IP) addresses of the first online activities identified in the first user data with the times of the second online activities and the Internet Protocol (IP) addresses of the second online activities identified in the second user data to identify mapping between the first user identifiers and the first account identifiers.
