Solution Overview

Problem

Existing technologies fail to effectively address fraudulent transactions by providing optimized proactive refunds for suspected and/or detected fraudulent transactions, leading to unnecessary revenue loss and inefficiencies in fraud chargeback protection services.

Innovation Solution

A system and method for optimizing refunds by determining the probability of chargebacks through a chargeback analysis profile, generating proactive refunds based on these probabilities, and adjusting thresholds to minimize unnecessary refunds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If automatic refund is provided for all reported fraudulent transactions, then possible chargebacks are prevented, but revenue is lost due to unnecessary refunds and the market for fraud chargeback protection service is narrowed

Engineering Contradiction:

Improvechargeback preventionVSAvoidrevenue loss

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system changes the parameter of refund decision from binary (all or none) to probabilistic by calculating a chargeback probability score based on multiple factors including transaction amount, customer behavior patterns, device information, and historical data. This allows differentiated treatment of fraudulent transactions based on their likelihood of actually resulting in chargebacks.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system incorporates feedback loops by continuously monitoring actual chargeback outcomes and using this information to refine and update the probability models. Historical data from previous fraudulent transaction reports and their subsequent chargeback results is fed back into the system to improve future prediction accuracy and optimize refund decisions.

Inventive Principle:

Principle #23Feedback

2Reliability

If proactive refund is provided for reported fraudulent transactions, then chargebacks are prevented, but approximately 10-20% of refunds do not prevent chargebacks resulting in unnecessary revenue loss

Engineering Contradiction:

Improvechargeback prevention effectivenessVSAvoidunnecessary revenue loss

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system performs preliminary analysis and probability calculation before issuing a refund. By assessing the chargeback probability score in advance and comparing it against threshold criteria, the system determines whether a proactive refund is likely to be effective, thereby avoiding unnecessary refunds in cases where they would not prevent chargebacks.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces a probabilistic parameter (chargeback probability score) to guide refund decisions. Instead of uniform treatment, transactions are evaluated based on their calculated probability of resulting in chargebacks, allowing the system to focus resources on high-probability cases where proactive refunds are most likely to be effective.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If fraud detection system analyzes multiple factors for chargeback probability, then refund optimization is achieved, but system complexity increases

Engineering Contradiction:

Improverefund optimization efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system segments the complex fraud analysis into distinct modular components: data collection modules (transaction data, customer behavior, device information), probability calculation modules (using machine learning models), and decision modules (refund issuance). This segmentation allows each component to be developed, tested, and optimized independently while working together to achieve overall system efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system employs a universal probability calculation framework that can handle multiple types of fraud detection scenarios and transaction types through a single integrated approach. The same core algorithms and data structures serve various functions including chargeback prediction, risk assessment, and refund optimization, reducing overall system complexity despite the multi-factor analysis.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method for optimizing refunds for suspected or detected fraudulent transactions includes receiving a chargeback analysis request for a potential chargeback transaction from a merchant or a payment processor extracting identifying information of transactions associated with the chargeback transaction from the chargeback analysis request, searching for a chargeback analysis profile in a profile database, determining whether the chargeback analysis profile exists in the profile database, upon determining that the chargeback analysis profile does not exist in the profile database, obtaining a new fraud analysis profile, determining, based on the chargeback analysis profile, a first probability that the potential chargeback transaction will result in a chargeback, determining, based on the chargeback analysis profile, a second probability that the potential chargeback transaction will result in a chargeback after a proactive electronic refund transaction, and generating a proactive electronic refund transaction based on the first probability and the second probability.
