Mobile Payment Authentication Using Geolocation for Fraud Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing commercial transaction systems fail to effectively address fraud, such as counterfeit credit cards and fraudulent merchant accounts, particularly when transactions occur in foreign locations.
Innovation Solution
A system and method that utilizes a payer's mobile communications device for authentication, incorporating geolocation and transaction history to verify the legitimacy of transactions by comparing the location of the payer's mobile device to the merchant's location and analyzing transaction history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods (PIN, password, physical card presence) are used, then transaction simplicity is maintained, but fraud detection capability deteriorates
Solution Approach 1:
The patent introduces a payment authentication device as an intermediary between the payer and merchant systems. This device contains a secure element that stores payment account information and authentication data, acting as a mediator that enables enhanced fraud detection through location verification while maintaining transaction simplicity for users. The secure element serves as the intermediary that bridges traditional card payments with modern location-based authentication.
Solution Approach 2:
The patent adds a spatial dimension to traditional authentication by incorporating location verification. Instead of relying solely on what the user knows (PIN) or has (card), the system now verifies where the transaction is occurring by comparing the merchant's location with the location data provided by the payment authentication device. This dimensional addition enhances reliability without significantly increasing user burden.
2Reliability
If location verification is implemented to detect fraudulent transactions, then transaction security is improved, but processing time increases
Solution Approach 1:
The patent performs location verification as part of the authorization process before the transaction is finalized. By checking whether the merchant's location matches the location associated with the payment authentication device during the authorization phase, the system ensures security without adding separate verification steps that would extend processing time. The location check is embedded within the existing authorization workflow.
Solution Approach 2:
The patent replaces physical verification mechanisms with electronic location data comparison. Instead of requiring manual verification of merchant identity or physical presence, the system uses electronic location information from the payment authentication device and compares it with merchant location data through automated electronic processes, significantly reducing processing time while maintaining security.
3Measurement precision
If comprehensive authentication data collection is performed, then fraud detection accuracy is improved, but data privacy concerns increase
Solution Approach 1:
The patent collects and processes location data locally within the payment authentication device's secure element rather than transmitting detailed personal information to external systems. The location verification process uses only the necessary location coordinates to compare merchant and device locations, maintaining fraud detection accuracy while minimizing privacy exposure by keeping sensitive data localized and processing it with strict access controls.
Solution Approach 2:
The patent uses ephemeral location tokens and temporary authentication credentials that are valid only for the specific transaction being authorized. These location-based authentication data are generated and consumed in real-time during the transaction process, providing high precision for fraud detection without creating persistent records that could compromise long-term privacy. The location data effectively serves its purpose and is then discarded.
Data Source
AI summary
In a transaction between a merchant and a payer, approval of the transaction may be provided by a payment processing system using authentication information provided from a mobile device of the payer. The authentication information may include a location of the payer mobile device which may be compared to a location of a merchant payment device such that the transaction is approved if the payer mobile device is within a defined distance of the merchant payment device.
