Zusammenfassung:A computer-implemented method for performing financial fraud assessment, the method includes receiving financial information associated with customer accounts that have been identified as being associated with suspicious financial activity; establishing communities for the customer accounts; creating a baseline set of features for each of the communities; receiving new financial information associated with customer accounts; updating the communities for the customer accounts based on the new financial information; extracting an updated set of features for each of the communities; and performing fraud assessment by determining whether a change between the updated set of features and the baseline set of features for each of the communities is indicative of an increased risk of fraud.
