GPS Location Verification for Secure Transaction Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transaction systems lack effective verification of a user's location at the time of a transaction, leading to fraudulent activities and subsequent financial losses for both users and retailers, as stolen credit or debit cards can be used for unauthorized purchases.
Innovation Solution
A location verification system that utilizes GPS information to compare the device's location to the transaction location, stored in a database, to ensure the user is present at the transaction site before completing the transaction, incorporating predetermined criteria for accuracy and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional payment verification methods are used, then transaction ease is maintained, but transaction security deteriorates due to stolen cards being accepted
Solution Approach 1:
The system performs preliminary location verification by comparing the user's current GPS location with the transaction location before completing the transaction. This advance check prevents fraudulent transactions using stolen cards, as the system will detect location mismatches and block the transaction before funds are transferred.
Solution Approach 2:
The patent introduces GPS location data as an intermediary verification factor between the user and the payment processing system. This additional layer of verification mediates the transaction approval process, requiring both location match and traditional authentication before completing the transaction, thus enhancing security without completely disrupting the payment flow.
2Reliability
If location verification is implemented, then fraudulent transactions are reduced, but system complexity increases
Solution Approach 1:
The system leverages the existing multi-functional smartphone device that already possesses GPS capabilities, camera, and communication functions. By utilizing these existing universal features for location verification, the system avoids adding dedicated hardware complexity while achieving enhanced transaction security through software-based verification.
3Measurement precision
If GPS location tracking is continuously monitored, then location accuracy is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous GPS monitoring, the system activates location tracking periodically or on-demand at critical transaction moments. The GPS location is retrieved only when a transaction is initiated, compared with the stored transaction location, and then the tracking stops. This periodic approach maintains location accuracy for security purposes while significantly reducing energy consumption compared to continuous monitoring.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This system effectively reduces fraudulent transactions by confirming the user's presence at the transaction location, thereby protecting both the user and the retailer from financial losses and ensuring secure transactions.
Implementation Method 1
The location of the device is determined through, for example, global positioning system information
Data Source
AI summary
A location verification provision is implemented to determine the location of a device associated with a user at the time of an attempted transaction. The attempted transaction includes receiving user identification and/or payment information, which is associated with the device in an entry stored in a database. Location information of the device, as well as a time at each location, may also be stored in the database. To verify that the device is located at the location of the transaction, a comparison operation may be performed. If the device is located where the transaction is being processed, the transaction may be completed. Predetermined criteria may be defined to account for possible inaccuracies in location and time calculations.
