Fraud Alerting via Mobile Location Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fraud mitigation techniques in credit card transactions are ineffective due to compromised information and erratic user purchase patterns, leading to high fraud levels and customer dissatisfaction.
Innovation Solution
A system that uses a user's mobile device location to determine the likelihood of fraud by comparing the device's location with the transaction location, alerting the user and issuer when a significant difference is detected, thereby enhancing fraud detection and prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If detailed behavioral models are built to detect fraud, then fraud detection accuracy improves, but false positives increase when users break their patterns
Solution Approach 1:
The patent introduces a new dimension for fraud detection by incorporating real-time location data from mobile devices. Instead of relying solely on historical purchase pattern models, the system compares the geographic location of the mobile device with the transaction location to establish spatial consistency. This dimensional addition allows the system to detect fraud even when purchase patterns are erratic, reducing false positives while maintaining detection accuracy.
2Measurement precision
If purchase models are made rigid to reduce false positives, then measurement precision improves, but fraud detection reliability decreases
Solution Approach 1:
The patent introduces location verification as an intermediary mechanism between the transaction system and the behavioral model. Rather than making the purchase model rigid or flexible, the system uses location data as an independent verification layer. This intermediary allows the system to maintain flexible purchase patterns while adding a reliable spatial check that reduces false positives without compromising fraud detection.
3Reliability
If location verification is added to transactions, then fraud detection reliability improves, but device complexity increases
Solution Approach 1:
The patent leverages the mobile device's own location capabilities (GPS, cell tower triangulation) to perform self-verification. The device automatically provides its location data without requiring additional hardware or complex user interaction. This self-service approach enables location-based fraud detection while minimizing the added system complexity, as the burden of location tracking is already inherent in mobile devices.
Data Source
AI summary
A location of a transaction or payment request is compared with a location of a user device to determine whether the distance is great enough to send an alert for a possible fraudulent transaction. The user device location may be predicted based on a last known location and information about the area of the last known location and movement of the user device.
