PROCESS AND APPARATUS FOR ASSIGNING A MATCH CONFIDENCE METRIC FOR INFERRED MATCH MODELING

摘要

Systems, methods, means, computer program code and computerized processes include receiving a first set of de-identified transaction data from a first transaction data source, receiving a second set of de-identified transaction data from a second transaction data source, removing data associated with an identifier field for each of the transactions in the first data set to created a de-identified first data set, removing data associated with an identifier field for each of the transactions in the second data set to create a de-identified second data set, and processing the first and second de-identified data sets using a probabilistic engine to establish a linkage between data in each data set. The probabilistic engine may assign probability scores to pairs of data profiles based on two-way matching of transactions and based at least partly on matching of transactions to nearest neighbors.

1. A computerized method, comprising:
receiving a first set of de-identified transaction data from a first transaction data source, the first set of de-identified transaction data having all personally identifiable information removed therefrom, the first set of de-identified transaction data representing a plurality of first profiles; receiving a second set of de-identified transaction data from a second transaction data source, the second set of de-identified transaction data having all personally identifiable information removed therefrom, the second set of de-identified transaction data representing a plurality of second profiles; and processing said first and second de-identified data using a probabilistic engine to establish a linkage between data in each data set, the linkage being a set of probability scores, each of said probability scores assigned to a respective pair of profiles, each of said pairs of profiles including one of said first profiles and one of said second profiles, at least some of said probability scores based at least in part, for a respective one of said pairs of profiles, on nearest neighbor matches for said respective pair of profiles; a nearest neighbor match being: (a) a match to a transaction associated with the respective first profile included in the respective pair of profiles by a one of said second profiles that is not included in the respective pair of profiles; or (b) a match to a transaction associated with the respective second profile included in the respective pair of profiles by a one of said first profiles that is not included in the respective pair of profiles.
