Solution Overview

Problem

Building a network that connects multiple organizations with different security approaches is difficult due to security concerns, making it challenging to construct a global model when networks are not constantly connected.

Innovation Solution

Implementing a learning apparatus that establishes secure communication with information terminals in each organization, acquires data sets, and integrates local models using secure communication protocols like VPNs and secure computation technologies to build a global model.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If secure communication protocols are implemented to connect multiple organizations with different security approaches, then the ability to construct a global model is improved, but the complexity of the communication system increases

Engineering Contradiction:

ImprovesecurityVSAvoidcommunication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a server as an intermediary that mediates communication between information terminals of different organizations. The server establishes secure communication channels with each terminal using protocols appropriate for that organization's security requirements, thereby enabling global model construction without requiring direct connections between organizations with different security approaches.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The communication system is segmented into independent communication channels between the server and each information terminal. Each channel can use different security protocols tailored to the specific organization's requirements, allowing the system to handle multiple security approaches without requiring a unified complex communication framework between all organizations.

Inventive Principle:

Principle #1Segmentation

2Reliability

If networks of multiple organizations are connected to construct a global model, then the performance of the global model is improved, but the difficulty of building the network increases due to different security approaches

Engineering Contradiction:

Improveglobal model performanceVSAvoidnetwork construction difficulty

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The server acts as a central intermediary that simplifies network construction by handling all communication with information terminals. This eliminates the need to build direct peer-to-peer networks between organizations with different security approaches, significantly reducing network construction difficulty while still enabling global model performance improvement through data aggregation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of having information terminals directly connect to each other to build the network, the approach is inverted by having all terminals connect to a central server. This reverses the network topology from a mesh structure to a star structure, making network construction easier while achieving the same goal of integrating data from multiple organizations.

Inventive Principle:

Principle #13The other way round (Inversion)

3Measurement precision

If data is collected from multiple organizations to build local and global models, then the accuracy of the models is improved, but the security risk of data transmission increases

Engineering Contradiction:

Improvemodel accuracyVSAvoiddata transmission security risk

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The server serves as a secure intermediary for data collection from multiple organizations. By routing all data transmission through the server with established secure communication channels, the system achieves high model accuracy through aggregated data while managing security risks through centralized control and protocol enforcement.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the security parameter by establishing secure communication protocols specifically for data transmission between the server and information terminals. This allows the system to maintain high model accuracy through data aggregation while transforming the security risk profile through encrypted and authenticated communication channels.

Inventive Principle:
