Location-Based Payment Authentication via GPS Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication systems for payment devices cannot verify if the person using the device is the authorized cardholder, as they lack the ability to confirm the user's location during transactions, making them vulnerable to fraud.
Innovation Solution
The system authenticates portable consumer devices by matching location data from a consumer's mobile communication device with the location data from a Point of Sale (POS) terminal, using a global positioning system (GPS) to ensure the transaction is conducted at the correct merchant location, thereby verifying the user's presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication systems are used, then payment transactions can be processed, but the system cannot verify if the user is the authorized cardholder
Solution Approach 1:
The patent introduces location data as an intermediary verification element between the user and the authentication system. By comparing location information from multiple sources (mobile device GPS and POS terminal), the system gains the ability to verify user presence without directly observing the user, thus resolving the contradiction between maintaining transaction processing and improving authentication reliability
Solution Approach 2:
The system implements feedback by continuously monitoring and comparing location data from different sources. The authentication decision is based on feedback from location matching - when the mobile device location and POS terminal location correspond, authentication is granted. This feedback mechanism transforms the authentication process from purely credential-based to location-verified, improving reliability without losing transaction processing capability
2Reliability
If location-based authentication is implemented, then fraudulent transactions are reduced, but the system complexity increases
Solution Approach 1:
The patent leverages the universal functionality of existing devices - mobile phones with GPS capabilities and POS terminals with location tracking - to perform authentication. Instead of introducing specialized authentication hardware, the system makes existing multi-functional devices serve the additional function of location verification, thereby improving fraud prevention while minimizing the increase in system complexity
Solution Approach 2:
The authentication system utilizes self-service capabilities where the mobile device and POS terminal automatically provide their own location data without requiring additional user input or specialized equipment. The devices serve themselves to verify location, reducing the burden on the authentication system and limiting the complexity increase to software processing rather than hardware additions
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 approach significantly reduces fraudulent transactions by ensuring that only authorized users can authenticate and complete transactions at the correct location, enhancing the security of payment processing systems.
Implementation Method 1
using a global positioning system (GPS) to ensure the transaction is conducted at the correct merchant location
Data Source
AI summary
A portable consumer device that is used to conduct a transaction at a merchant is authenticated. Information provided to a server computer includes locations of a merchant and a mobile communication device possessed by a consumer. If the location of the mobile communication device corresponds to the location of the merchant, the portable consumer device that is used to conduct the transaction is authenticated.
