Solution Overview

Problem

Current biometric recognition systems in online transactions suffer from inefficiencies due to unidirectional communication between devices, leading to repeated biometric feature collection and failed transactions when the payment receiving device is not ready, prolonging processing times and reducing efficiency.

Innovation Solution

Implement a voice-enabled biometric recognition method where a payee initiates a voice enabling instruction after constructing a transaction order, allowing the biometric recognition device to enable its function based on voiceprint matching, collect the payer's biometric feature, and complete the transaction, thus avoiding unnecessary feature collection and improving efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If unidirectional communication mode is used between biometric recognition transaction device and payment receiving device, then device complexity is reduced, but transaction processing efficiency deteriorates due to repeated biometric feature collection

Engineering Contradiction:

Improvecommunication mode complexityVSAvoidtransaction processing efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent introduces feedback mechanism where the payment receiving device sends status information back to the biometric recognition transaction device about its readiness state. This allows the biometric device to adjust its behavior accordingly - only collecting biometric features when the payment device is ready, thereby avoiding repeated collection cycles and improving transaction processing efficiency while maintaining unidirectional communication simplicity

Inventive Principle:

Principle #23Feedback

2Speed

If biometric feature collection is performed without checking payment receiving device readiness, then operation speed is improved, but reliability deteriorates due to failed transactions requiring re-collection

Engineering Contradiction:

Improvebiometric feature collection speedVSAvoidtransaction success rate

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent implements preliminary action by having the biometric recognition transaction device first query the payment receiving device's readiness status before collecting biometric features. This preliminary check ensures that the payment device is ready to receive and process the biometric data, preventing collection of invalid features and subsequent transaction failures, thereby improving reliability without significantly impacting speed

Inventive Principle:

Principle #10Preliminary action

3Reliability

If repeated biometric recognition is performed due to invalid features, then transaction completeness is improved, but loss of time increases due to prolonged processing

Engineering Contradiction:

Improvetransaction completenessVSAvoidonline payment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The feedback mechanism from the payment receiving device about its readiness state enables the biometric recognition system to collect features only when appropriate. This eliminates the need for repeated recognition cycles and ensures transaction completeness in a single attempt, significantly reducing online payment time and avoiding time loss from retries

Inventive Principle:

Principle #23Feedback

AI summary

Techniques for processing transaction data using biometric recognition are described. A payment receiving device constructs a transaction order and transmits a voice enabling instruction initiated by a payee. A biometric recognition device performs one-way communication with the payment receiving device, extracts a voiceprint feature from the instruction, and matches it against a stored target voiceprint. If a match is found, the biometric recognition function is enabled to collect a payer's biometric feature. A payer account is obtained based on the collected feature, and transaction payment is completed using the payer account, a virtual resource, and a payee account specified in the transaction order. By employing these techniques, repeated processing during payment transactions is reduced and overall transaction efficiency is improved.
