Abstract

A method for improving fraud scoring based on criminal activity includes: storing transaction data entries, each including transaction data related to a payment transaction and a transacting consumer identifier; storing consumer profiles, each including data related to consumers including consumer characteristics and a consumer identifier; storing fraud scoring rules, each being configured to score a payment transaction for a likelihood of fraud based on transaction data; receiving a criminal activity notification, the notification including criminal characteristics associated with criminals or victims associated with untrustworthiness or fraud; identifying a specific consumer profile where a predefined number of the consumer characteristics correspond to the criminal characteristics; identifying a subset of transaction data entries where the transacting consumer identifier corresponds to the consumer identifier in the specific consumer profile; and updating the fraud scoring rules based on the transaction data included in each transaction data entry in the subset.
