Patent ID: 8719193

Claim:
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; 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; filtering said first and second sets of de-identified transaction data to identify transactions in each of said first and second sets of de-identified transaction data associated with at least a first entity and to create first and second filtered data sets including the identified transactions; performing a pattern analysis on said data in said first filtered data set to identify a frequency of transactions in said first filtered data set; removing data associated with an identifier field for each of said transactions in said first filtered data set and creating a first lookup table entry associating said data associated with the identifier field for each of said transactions in said first filtered data with a profile ID to create a de-identified first data set; performing a pattern analysis of said data in said second filtered data set to identify a frequency of transactions in said second filtered data set; removing data associated with an identifier field for each of said transactions in said second filtered data set and creating a second lookup table entry associating said data associated with the identifier field for each of said transactions in said second filtered data with a profile ID to create a de-identified second data set; and processing said first and second de-identified data sets based on the profile IDs of said first and second de-identified data sets using a probabilistic engine to establish a linkage between data in each data set, the linkage being a probability score representing a probability match between the first and second de-identified data sets.
