Location-Aware Mobile Payment Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of mobile devices for financial transactions introduces new security risks due to the potential for unauthorized or unintended transfers, as these devices can initiate transactions from anywhere, lacking the physical verification of transaction parties.
Innovation Solution
Implementing location-aware techniques in mobile devices to determine the physical proximity of transaction parties, allowing financial institutions or transaction processors to take security measures such as disallowing transactions or requiring additional authorization if parties are not near each other, thereby reducing fraudulent activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile devices are used to initiate financial transactions from anywhere, then convenience and accessibility of transactions are improved, but security risks and potential for unauthorized transfers increase
Solution Approach 1:
The patent introduces location information as an intermediary factor to verify the legitimacy of transaction requests. By comparing the location of the mobile device with the location of the transaction counter or merchant, the system mediates between the convenience of remote transactions and the need for security verification, allowing transactions to proceed when location data confirms authenticity while blocking potentially fraudulent remote requests
2Reliability
If location-aware techniques are implemented to verify physical proximity of transaction parties, then transaction security is improved, but device complexity and processing requirements increase
Solution Approach 1:
The mobile device automatically performs location determination and inclusion of location data in transaction requests without requiring manual intervention from the user. The device's built-in location capabilities serve themselves to provide security verification, eliminating the need for complex external verification systems while maintaining high security standards
3Object-affected harmful factors
If additional authorization measures are required when parties are not physically proximate, then fraud prevention is improved, but transaction speed and user experience deteriorate
Solution Approach 1:
The patent implements dynamic authorization requirements based on location verification results. When location data confirms physical proximity, transactions proceed with standard authorization at full speed. When location data indicates remote transactions, the system dynamically adjusts by requiring additional authorization measures, thereby preventing fraud while minimizing impact on legitimate transaction speed
Data Source
AI summary
A mobile payment network receives a payment request from a first user operating a first mobile device and identifies recipients of the payment request based at least in part on the proximity of other mobile devices to the first mobile device.
