Abstract

Techniques are provided for fraud mitigation using enhanced spatial features. One method comprises obtaining transaction data associated with a transaction; obtaining a machine learning module trained using training transaction data for multiple geographic areas to learn a correlation of the training transaction data with fraudulent activity for each geographic area; extracting a transaction address from the transaction data; determining a given geographic area for the transaction using the transaction address; determining values for a predefined spatial feature for a predefined region that includes the transaction address in the given geographic area using a query of an external online data source; applying the determined values for the predefined spatial feature to the machine learning module to obtain an anomaly score for the transaction; and initiating a predefined remedial step and/or a predefined mitigation step when the transaction is determined to be a predefined anomaly based on the anomaly score.
