Solution Overview

Problem

Current systems for determining cardholder location data and merchant location information suffer from high latency, leading to inaccurate transaction authorizations, false fraud flags, and inefficient predictive capabilities, particularly for mobile-location merchants and account holders traveling without updating their issuer.

Innovation Solution

A system that continuously monitors and stores geolocation data from mobile devices, updating location records in a persistent storage system for low-latency access, allowing real-time location data to be used for transaction authorizations and merchant location type classification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the system queries mobile device location data through mobile carriers or third-party services at the time of transaction, then authentication accuracy is improved, but process latency becomes too great for real-time authorization

Engineering Contradiction:

Improvelocation data accuracyVSAvoidauthorization latency

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system pre-obtains and stores account holder location data before the transaction occurs. The processor receives updated location information from the mobile device, determines whether new location data exists, generates entries in data groups for storage, and stores this location data in advance. This preliminary action eliminates the need for real-time queries during transaction authorization, reducing latency while maintaining accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a copy of the account holder's location data and stores it in a data group within the system. Instead of querying the mobile device or third-party services during transaction processing, the system retrieves the pre-stored location data copy, significantly reducing authorization latency while maintaining location accuracy for fraud detection.

Inventive Principle:

Principle #26Copying

2Productivity

If the system uses stored merchant address data for location comparison, then transaction processing speed is improved, but location accuracy decreases due to outdated or incorrect merchant address records

Engineering Contradiction:

Improvetransaction processing speedVSAvoidmerchant location accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system continuously updates merchant location data by receiving updated location information from mobile devices associated with account holders conducting transactions. When new location data is received, the system determines whether it represents updated information, generates entries in data groups, and stores the updated merchant location data. This feedback loop ensures merchant location accuracy is maintained while enabling fast transaction processing through pre-stored data.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system pre-updates merchant location data by continuously monitoring and storing updated location information from mobile devices before transactions occur. This preliminary updating of merchant location records ensures that when transactions are processed, the system uses accurate, up-to-date location data rather than outdated stored addresses, maintaining both speed and accuracy.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the system continuously monitors and stores updated location data from mobile devices, then real-time authorization accuracy is improved, but system complexity and data storage requirements increase

Engineering Contradiction:

Improvetransaction authorization reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments location data storage into data groups, where each data group contains entries for specific account holders or merchants. The processor determines whether received location information represents updated data, generates appropriate entries in the relevant data group, and stores only the necessary location data. This segmentation reduces overall system complexity by organizing data efficiently and storing only relevant information.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system automatically processes incoming location data by determining whether it represents updated information, generating appropriate data group entries, and storing the data without requiring manual intervention. This self-service approach to data management reduces operational complexity while maintaining high reliability in transaction authorization through continuous, automated location data updates.

Inventive Principle:

Principle #25Self-service

AI summary

A system includes one or more memory devices storing instructions, and one or more processors configured to provide low-latency access to cardholder location information by receiving periodically updated location information from a mobile device associated with the account holder and updated associated systems with the information prior to the user initiating a transaction. At the time of a transaction, necessary systems can quickly access the stored information and authenticate transactions appropriately.
