Mobile Device Geolocation Caching for Tap and Pay Fraud Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for authenticating 'tap & pay' transactions using RFID devices are inadequate as they cannot verify identity in real-time, making them susceptible to fraudulent activities due to the lack of immediate geolocation capabilities, which is essential for preventing unauthorized transactions.
Innovation Solution
A method that utilizes cached position information from a user's mobile device to determine its geographical location before a transaction occurs, allowing for rapid authentication by comparing the device's location to the transaction location, thereby generating alerts for potential fraudulent activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If RFID devices are used for tap & pay transactions, then convenience and speed of payment are improved, but security is worsened due to susceptibility to fraudulent activities
Solution Approach 1:
The system performs geolocation verification of the mobile device before authorizing the transaction. By checking whether the device is physically present at the merchant location in advance of completing the payment, the system prevents fraudulent transactions while maintaining rapid processing speeds.
Solution Approach 2:
The patent introduces mobile device geolocation data as an intermediary verification layer between the RFID tap & pay transaction and the authorization system. This intermediary check confirms the user's physical presence without adding significant time to the transaction process.
2Reliability
If geolocation verification is performed for each transaction, then fraud detection capability is improved, but authentication time is worsened
Solution Approach 1:
The system caches the mobile device's geolocation data in advance, so that during the transaction the system only needs to retrieve and compare cached position information with the merchant location. This preliminary caching action eliminates the need for real-time geolocation queries during the transaction, maintaining sub-second authentication times.
Solution Approach 2:
The patent uses cached copies of the mobile device's position information rather than querying the device's current location in real-time. This copying approach allows rapid verification without the time delay of live geolocation services.

AI summary
The invention provides a method for verifying the identity of an internet user, or for detecting the misuse of an identity, during an on-line transaction. The method involves comparing the geographic location of the transaction to the geographic location of the user's cell phone or other mobile device, and taking a geographically close location relationship between the two as a positive indication of identity. Various additional factors are taken into account so as to reduce the incidence of false negatives, and to improve the reliability of positive identifications.
