Solution Overview

Problem

Existing biometric authentication systems for networked devices lack secure and customizable solutions for multiple users, leading to generic default settings and loss of customization when multiple users connect, as each user overrides previous settings.

Innovation Solution

A system where a secure user device stores user profile data and biometric information, encrypts it, and transmits encrypted data to networked devices, which use a decryption key to apply user-specific settings and verify biometrics before customization, ensuring secure and customizable operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric authentication is implemented for networked devices, then user security and verification reliability are improved, but the system complexity and data management requirements increase

Engineering Contradiction:

Improveuser verification reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system divides authentication data into two separate components: biometric information stored securely in the user device and device profile information stored on the networked device. This segmentation allows biometric verification to remain reliable while preventing the networked device from handling sensitive biometric data, thereby reducing system complexity and security risks.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary mechanism where the user device acts as a secure mediator that transmits encrypted device profile information to the networked device after biometric verification. This intermediary approach ensures that the networked device never directly accesses or stores biometric data, maintaining verification reliability while simplifying the overall system architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If user profile data is stored on networked devices, then customization and user preferences are improved, but data security and privacy protection deteriorate

Engineering Contradiction:

Improveuser customizationVSAvoiddata security risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts sensitive device profile information from the user device's secure storage and transmits it to the networked device only after biometric verification. This extraction approach allows the networked device to apply user customizations and preferences while the original secure storage location remains protected, maintaining both customization capability and data security.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary biometric verification on the user device before transmitting any device profile information to the networked device. This preliminary action ensures that only authenticated users can access or modify customization data, preventing unauthorized access while allowing legitimate users to maintain their preferences on the networked device.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If multiple users connect to the same networked device, then device accessibility and ease of operation are improved, but loss of customization and settings override occur

Engineering Contradiction:

Improvedevice accessibilityVSAvoidcustomization loss

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent implements local quality by associating specific device profile information with individual users through biometric verification. Each user's customized settings and preferences are stored and applied locally to their authenticated session, ensuring that one user's customizations do not override another user's settings, thereby maintaining both accessibility and customization integrity.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system dynamically switches between different user profiles based on biometric verification. When a user authenticates, the networked device dynamically loads and applies that user's specific device profile, allowing multiple users to access the device with full customization for each user without settings conflict or loss.

Inventive Principle:

Principle #15Dynamics

4Object-affected harmful factors

If encrypted data transmission is implemented, then data security is improved, but processing time and computational requirements increase

Engineering Contradiction:

Improvedata securityVSAvoidprocessing time

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent applies encryption selectively only to the device profile information that needs to be transmitted from the user device to the networked device, rather than encrypting all data. This partial encryption approach maintains data security for sensitive information while minimizing the computational overhead and processing time required for encryption and decryption operations.

Inventive Principle:

Principle #16Partial or excessive action
