Vehicle Fuel Fraud Detection via GPS and Sensor Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fuel purchase card monitoring systems are inadequate in detecting fraudulent transactions due to incomplete and inaccurate location data from gas stations, allowing misuse of company vehicles for personal purposes and lack of verification on fuel usage.
Innovation Solution
A vehicle-linked credit card system equipped with a mobile data unit containing information gathering devices such as a GPS receiver, fuel meter, and ignition sensor, which monitors vehicle activity and compares it with credit card transaction data to detect fraudulent purchases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If addresses from credit card company are used to identify gas station locations, then transaction monitoring is enabled, but location accuracy deteriorates due to geocoding failures
Solution Approach 1:
A GPS receiver mounted on the vehicle acts as an intermediary device to obtain location information. Instead of relying on the credit card company's address data which may fail to geocode, the GPS receiver directly captures the vehicle's location at the time of fueling, providing accurate coordinates that can be correlated with transaction data.
Solution Approach 2:
The patent replaces the mechanical/address-based location identification system with an electronic GPS-based system. The GPS receiver electronically captures location data, which is then transmitted and correlated with fuel card transactions, substituting the unreliable address matching process with precise satellite-based positioning.
2Device complexity
If fuel card transactions are monitored using only credit card data, then transaction recording is simple, but fraud detection capability deteriorates due to lack of vehicle activity verification
Solution Approach 1:
The patent merges two previously separate monitoring systems: the fuel card transaction monitoring system and the vehicle activity monitoring system (with GPS receiver, ignition sensor, and fuel meter). By combining these systems and correlating their data, the patent creates a comprehensive monitoring solution that maintains reasonable complexity while significantly improving fraud detection reliability through cross-verification of transaction data with actual vehicle activity.
Solution Approach 2:
The system implements feedback by continuously comparing fuel card transaction data with independent vehicle activity data from GPS, ignition sensors, and fuel meters. When discrepancies are detected (such as fueling transactions not matching vehicle location or engine status), the system can trigger alerts or prevent further transactions, creating a self-correcting monitoring mechanism that improves reliability without proportionally increasing complexity.
3Loss of information
If vehicle-linked credit cards are used for fuel purchases, then purchase tracking is enabled, but verification of actual fuel usage deteriorates due to inability to confirm vehicle presence at gas station
Solution Approach 1:
The GPS receiver, ignition sensor, and fuel meter continuously monitor and record vehicle activity before, during, and after fueling transactions. This preliminary action of collecting location and engine status data ensures that when a fuel card transaction occurs, there is already verified information confirming the vehicle's presence and operational state, enabling accurate verification of actual fuel usage.
Data Source
AI summary
In a fuel card monitoring system the vehicle associate with the fuel card is provided with a transmitter and possibly a memory for relaying information associated with a credit transaction, relating to one or more of the vehicle position, the number of miles driven, the amount of fuel taken in, and the turning off and on of the vehicle engine. Information gathering devices may be provided on the vehicle for monitoring the fuel amount, the timing information and the location of the vehicle.
