Behavioral Biometric Transaction Authentication for Fraud Screening

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing transaction verification systems struggle to authenticate the user's identity, leading to increased fraud risk and computational inefficiencies, as they often rely on additional information like CVV which does not verify the user's identity effectively.

Innovation Solution

Implement a system that uses behavioral biometric data to authenticate transactions by communicating an authenticity assessment request to a behavioral biometrics server, which generates a response based on user and device patterns, allowing for quicker identification and reducing fraudulent transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional security authentication methods (such as requesting CVV) are implemented to verify transaction validity, then fraud detection capability is improved, but the ability to effectively verify user identity deteriorates

Engineering Contradiction:

Improvefraud detection capabilityVSAvoiduser identity verification accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The patent replaces traditional mechanical authentication methods (CVV verification, manual identity checks) with a biometric-based authentication system. The system captures behavioral biometric data during the transaction process and uses machine learning models to verify user identity, achieving both improved fraud detection and accurate identity verification simultaneously.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary authentication system that acts as a bridge between the transaction system and the user. This intermediary system collects behavioral biometric data, processes it through authentication algorithms, and provides verification results to the transaction system, enabling effective identity verification without disrupting the existing transaction flow.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If transaction verification systems request additional information (CVV, etc.) to counter fraud, then security scrutiny is improved, but processing time and computational resources deteriorate

Engineering Contradiction:

Improvetransaction security scrutinyVSAvoidtransaction processing efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent performs preliminary authentication by collecting and analyzing behavioral biometric data during the natural course of the transaction interaction, before making a fraud determination. This preliminary action allows the system to pre-verify user identity using already-collected behavioral data, avoiding the need for additional time-consuming verification steps later in the process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent maintains continuous authentication by integrating behavioral biometric data collection throughout the entire transaction process rather than adding discrete verification steps. The system continuously monitors user behavior patterns during the transaction and uses this ongoing data stream for real-time fraud assessment, eliminating interruptions and maintaining processing flow.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If systems perform additional scrutiny on transactions to determine fraud, then fraud detection is improved, but computational resources and processing time deteriorate

Engineering Contradiction:

Improvefraud detection accuracyVSAvoidcomputational resource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial scrutiny by using behavioral biometric data to assess fraud risk and only performing full verification on transactions that exceed a certain risk threshold. For low-risk transactions that exhibit normal behavioral patterns, the system approves them with minimal computational overhead, while reserving intensive scrutiny for suspicious cases, thereby reducing overall computational resource consumption.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent changes the parameters of fraud detection by shifting from verifying static information (CVV, personal details) to analyzing dynamic behavioral parameters (typing patterns, interaction sequences, temporal patterns). This parameter change enables more efficient fraud detection that leverages naturally occurring behavioral data rather than requiring additional computational verification of static credentials.

Inventive Principle:

Principle #35Parameter changes

AI summary

Provided are a system, method, and computer program product for authenticating a transaction based on behavioral biometric data. The method includes receiving an authorization request message associated with a transaction between a merchant system and a payment device. The method also includes determining that an additional security authentication should be applied to the authorization request message based on transaction data. The method further includes communicating an authenticity assessment request to a behavioral biometrics server computer and receiving, from the behavioral biometrics server computer, an authenticity assessment response generated based on at least a portion of the transaction data. The method further includes generating, based on the authenticity assessment response, an authentication response message configured to authenticate or decline the transaction.
