Introduction
The sample project will show how to detect online booking fraud based on Fraud Rating Score.
Scenario
In this example, we used commonly available Fraud Rating Scores to determine the online booking fraud. Based on the Fraud Rating Score, the system can either approve or reject the transaction. If the score is within a pre-defined acceptable range, the transaction is approved. If the score is too high, the transaction will be rejected. If the score is within pre-defined buffer range, the transaction is flagged as potentially fraudulent and may be reject or approve after reviewing by a fraud analyst.
The calculated Fraud Rating Score should be less than 200 to approve the online booking. If the score is over 300, the booking will be rejected. If the score fall in between those two margins, the transaction will be flagged and forwarded to a fraud analyst to review further.
Running the Sample
- Open the file Workflow.xml
- Click on the Logic Run template.
- Click on any given template.
- Debug the sample by clicking on the debug button in the Logic Run Template window.
- You can click the ‘Next Step’ button to go step by step to follow the flow.
- If you select “Flagged” run template, you will have the following window to select either Approve or Reject decision outcome.
- Now you can see the output values in the ‘Parameters’ window.
- You can see the notifications in the Notification window base on the actions you perform.
Process Steps
The process contains the following two steps to determine “Online Booking Fraud”
- Straight through processing for determine Fraud Decision
- Fraud Analyst’s Decision
Project Description
The project contains the following documents.
- Determine History based Fraud Score.xml – Determine the score based on customer’s order history.
- Determine Payment Method based Fraud Score.xml – Based on different payment method, the score will be calculated.
- Determine Product based Fraud Score.xml – Based on different products, the score will be calculated.
- Determine Fraud.xml – Determines the fraud status and decision outcome based on the Fraud Rating Score.
Business Glossaries
- Concept.xml – Allows to reuse the customer, booking and outcome details throughout the process.
Decision Graph
- Fraud Decision.xml – Determines the fraud decision based on the score.
Workflow
- Workflow.xml – Overall flow of the process. If the fraud decision is flagged, it refer to a fraud analyst as a human task.
The Flow Design
The Fraud Decision (Decision Graph)
1. Decision Table to calculate score based on product type.
2. Decision Table to calculate the score based on payment method.
3. Decision Table to calculate the score based on customer booking history.
4 Expression for check the active disputes.
5 Compute Fraud Rating Score : This sub decision invokes the above sub decisions and sums up the calculated fraud score from each.
6. Decision Table to determine the booking fraud based on Fraud Rating Score.
The Workflow Design
The Workflow contains the Fraud Decision (Decision Graph) and a human task with 2 notifications based on the human task action.
If the Fraud Decision outcome is ‘Flagged’, then Fraud Analyst’s Decision will execute. Otherwise, the process will end. Fraud Analyst’s Decision can be either ‘Approve’ or ‘Reject’. Based on that decision, relevant notification will display.
