Solution Overview

Problem

Existing systems fail to effectively mitigate cross-entity refund fraud due to a lack of data sharing and coordination between merchants and payment processors, allowing fraudsters to exploit vulnerabilities and successfully obtain refunds without returning purchased goods.

Innovation Solution

Implementing a real-time fraud alert system that enables data sharing and real-time notifications between entities involved in transactions, such as payment processors and merchants, to detect and mitigate refund fraud by sharing fraud alerts and risk assessment data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If merchants and payment processors operate independently without data sharing, then each entity maintains operational autonomy and simplicity, but refund fraud detection capability deteriorates due to lack of coordinated information

Engineering Contradiction:
Improverefund fraud detection capabilityVSAvoiddata sharing system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A fraud alert system acts as an intermediary between merchants and payment processors, enabling data sharing without requiring direct integration between these entities. The system receives fraud alerts from either party and distributes relevant information to the other, improving coordinated fraud detection while maintaining operational independence of each entity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The fraud detection system is segmented into independent components: merchants can implement their own fraud alert systems, payment processors can implement theirs, and they connect through the fraud alert system. This allows each entity to maintain its own operational complexity level while benefiting from coordinated detection through selective data sharing.

Inventive Principle:
Principle #1Segmentation

2Speed

If real-time fraud alert systems are implemented, then refund fraud detection speed improves, but system operational complexity increases due to integration requirements

Engineering Contradiction:
Improvefraud detection speedVSAvoidsystem integration complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The fraud alert system serves as a mediator that simplifies real-time communication between merchants and payment processors. Instead of requiring complex direct integration, each party connects to the fraud alert system using standard protocols, enabling rapid fraud alert dissemination without proportionally increasing integration complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If comprehensive data sharing is implemented between entities, then fraud detection accuracy improves, but information security risks increase due to broader data exposure

Engineering Contradiction:
Improvefraud detection accuracyVSAvoidinformation security risks
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The fraud alert system implements selective data sharing where only specific fraud-relevant information is exchanged between entities rather than comprehensive data sharing. This allows accurate fraud detection through targeted information exchange while minimizing information security risks by limiting data exposure to only what is necessary for fraud detection.

Inventive Principle:
Principle #3Local quality

4Reliability

If multiple fraud mitigation measures are implemented across entities, then refund fraud prevention effectiveness improves, but operational overhead increases due to coordination requirements

Engineering Contradiction:
Improvefraud prevention effectivenessVSAvoidcoordination time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fraud alert system establishes pre-defined protocols and thresholds for fraud alert generation and response. When fraud indicators meet predetermined criteria, alerts are automatically generated and distributed without requiring real-time human coordination, thus improving prevention effectiveness while minimizing coordination time overhead.

Inventive Principle:
Principle #10Preliminary action

AI summary

Methods and systems are presented for cross-entity fraud mitigation. A refund request for a transaction between a first entity and a second entity is received via a network from a device of the first entity. A transaction history associated with an account of the first entity with a service provider is obtained. From the obtained transaction history, metadata relating to previous refund requests processed for previous transactions associated with the account of the first entity is extracted. The extracted metadata is evaluated to determine a risk score for the refund request received for the transaction, where the risk score indicating a risk of fraud associated with the refund request. A decision on authorization of the refund request is generated for the transaction, based on the risk score. A notification of the decision is transmitted via the network to a device of the second entity.
