Abstract: Identification of anomalous transaction attributes in real-time with adaptive threshold tuning is provided. A set of historical transactions conducted during a defined time period are analyzed and categorizing into defined groups. Outlier transactions are identified and removed from the set of historical transactions and a set of non-anomalous transactions are determined. When a new transaction is received, the new transaction is automatically allowed based on a determination that the subsequent transaction conforms to the set of non-anomalous transactions. Alternatively, an alert for further analysis for the new transaction is output based on a determination that the subsequent transaction does not conform to the set of non-anomalous transactions.
