Abstract: Systems and methods for filtering data representative of consumers targeted for marketing campaigns that include receiving, at a first computer system operating on behalf of a payment card network, a first data set comprising pseudonymized data of a plurality of consumers derived from respective consumer files, the pseudonymized data of each consumer including a unique artificial identifier for the consumer, the first data set being received from a second, independent computer system storing keys configured to re-identify at least some of the pseudonymized data of the first data set; comparing, at the first computer system, the pseudonymized data of each of the consumers with payment card network criteria to generate a second data set comprising a subset of the first data set corresponding to a qualifying subset of the consumers and unique artificial identifiers included in the first data set; and transmitting the second data set from the first computer system to the second computer system.
