The Fraud Detection Scenario

The tutorial is built on a simplified fraud detection scenario and decision making flow.

To establish whether fraud is suspected, the runtime engine correlates the frequency of and amount of debits in a rolling time window, and flags accounts that satisfy both of the following criteria:

• The account incurs more than three debit transactions in a two-minute period.
• The sum of the debits that occurred in the two minute period totals more than 80% of the average monthly balance of the account.

For the purpose of the tutorial, messages arrive from an HTTP server, provided by TIBCO BusinessEvents. The event correlation is performed using simple TIBCO BusinessEvents rules. Suspicious accounts are simply set to “Suspended.” Actions are printed to the monitor so you can see the project in action.

An additional event and rule not shown allow you to unsuspend an account.
