Solution Overview

Problem

Current financial management services face security issues due to stolen passwords and identity recognition devices, leading to increased labor costs and insecure personal property.

Innovation Solution

A multi-factor authentication system utilizing user devices, financial management stations, and a cloud-based biometric server apparatus that processes and encodes biometric data for secure authentication, without storing the data, to enhance security and reduce costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric data is stored for authentication, then authentication reliability is improved, but security risk increases and storage costs increase

Engineering Contradiction:
Improveauthentication reliabilityVSAvoidsecurity risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts only the essential biometric features from complete biometric data for authentication purposes. The biometric server apparatus processes biometric information to extract distinctive features (such as facial geometry, voice characteristics, or fingerprint patterns) and stores only these extracted features rather than the original biometric data, thereby reducing security risks while maintaining authentication reliability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates encoded representations of biometric data in the form of feature vectors or templates that serve as functional copies for authentication. These encoded copies contain sufficient information for verification purposes but are rendered unusable for identity reconstruction or unauthorized access, thus balancing reliability with security

Inventive Principle:
Principle #26Copying

2Measurement precision

If complete biometric data is stored, then authentication accuracy is improved, but storage costs and processing time increase

Engineering Contradiction:
Improveauthentication accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system extracts only the critical authentication features from biometric data, storing compressed feature representations rather than complete datasets. This extraction process identifies and retains only the most discriminative characteristics needed for accurate authentication, reducing both storage requirements and processing time while preserving authentication accuracy

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms biometric data into different parameter representations through feature extraction and encoding. By converting raw biometric information into optimized feature vectors with adjusted dimensions and characteristics, the system achieves efficient storage and rapid processing while maintaining the precision required for accurate authentication

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If traditional authentication methods (password, card) are used, then ease of operation is maintained, but security reliability deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidsecurity reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces mechanical authentication systems (physical cards, written passwords) with biometric-based authentication. This substitution eliminates the vulnerabilities of traditional methods such as card theft, password leakage, and replication, while maintaining ease of operation through automatic biometric capture and recognition processes that require minimal user effort

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A multi-factor authentication system for financial management may provide user a convenient and safe financial management service via enrolling with service for multi-factor authentication via an application. The user may log in the multi-factor authentication service platform during the enrollment phase via the application to acquire an account and obtain authority for use, thereby to access the service provided by the multi-factor authentication service platform via a financial management station system. In addition, during the financial management service, the user may acquire the financial management service in fewer steps and a more secure manner during an authentication phase with the multi-factor authentication service platform, thereby to enforce security for identity authentication. The multi-factor authentication for financial management may address concerns for the user property security and identity authentication during financial management.
