Online Financial Transaction Geolocation Checks to Reduce False Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fraud detection systems generate a high number of false positive alerts, leading to significant resource drain and customer annoyance, as they often have a low threshold for triggering fraud alerts to ensure capturing actual fraud.
Innovation Solution
Implement geolocation-based techniques to verify the location of a cardholder during an online transaction, comparing it with the expected location of the authorized cardholder, and preventing or confirming transactions based on this verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a low threshold is used to trigger fraud alerts to ensure capturing actual fraud, then fraud detection reliability is improved, but the number of false positive alerts increases
Solution Approach 1:
The system segments the fraud detection process into multiple independent verification stages: initial fraud rule evaluation, geolocation data retrieval, location matching, and final alert generation. Each stage operates independently with its own criteria, allowing the system to maintain a low initial threshold while filtering false positives through subsequent segmentation steps.
Solution Approach 2:
Geolocation data serves as an intermediary element between the transaction alert and the final fraud determination. The system introduces location information as a mediating factor that verifies whether the transaction context matches the cardholder's expected location, thereby reducing false positives without compromising fraud detection sensitivity.
2Reliability
If numerous fraud alerts are generated to capture actual fraud, then fraud detection coverage is improved, but human resource drain increases
Solution Approach 1:
The system performs preliminary geolocation verification automatically before human review is needed. By pre-processing alerts through location-based validation, the system eliminates many false positives in advance, reducing the volume of alerts requiring human investigation and thereby decreasing time loss and resource drain.
Solution Approach 2:
The fraud detection system performs self-service verification by automatically comparing transaction locations with cardholder location data. This automated self-validation reduces dependence on human resources for initial screening, allowing human investigators to focus only on alerts that pass the automated geolocation check.
3Reliability
If numerous fraud alerts are generated to capture actual fraud, then fraud detection coverage is improved, but customer annoyance increases
Solution Approach 1:
Geolocation verification is performed preliminarily and automatically to filter out false positive alerts before they reach customers. By pre-validating transaction locations against cardholder location data, the system prevents spurious alerts from being communicated to customers, thereby reducing annoyance while maintaining comprehensive fraud detection coverage.
Data Source
AI summary
In a method of preventing fraudulent online financial transactions, a request to authorize an online, financial transaction may be received, where the transaction is associated with a debit or credit card account. A computing device at which information associated with the debit or credit card account was entered for the transaction may be identified, and a first geographic location at which the computing device resides may be determined. Based upon geolocation data indicating one or more geographic locations of the authorized cardholder, it may be determined that the authorized cardholder was at a second geographic location at a time of the transaction. If the second geographic location does not correspond to the first geographic location, the financial transaction may be prevented from being executed.
