Solution Overview

Problem

Existing owner identity confirmation systems face challenges in verifying that multiple terminals belong to the same owner, particularly when different certificate issue servers are involved, leading to potential fraudulent key copying and personal information leakage.

Innovation Solution

An owner identity confirmation system where terminals and terminal management servers exchange identity confirmation information through a communication network, using a process that involves requesting and verifying owner identity confirmation start requests, inter-server owner identity confirmation requests, and responses to determine if the owners are the same, while preventing fraudulent information leakage by limiting data exchange to terminal management servers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single certificate issue server is used to issue owner certificates to all terminals, then the system is simple to manage, but it cannot support multiple terminal types and manufacturers

Engineering Contradiction:

Improvesupport for multiple terminal types and manufacturersVSAvoidsystem complexity with multiple certificate issue servers

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a multi-server architecture where each certificate issue server can independently issue owner certificates to terminals. The servers communicate through standardized protocols to achieve universal functionality across different terminal types and manufacturers, allowing the system to adapt to diverse devices without requiring a single monolithic server

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system divides the certificate issuance function into multiple independent certificate issue servers, each capable of handling specific terminal types or manufacturers. This segmentation allows flexible deployment and management while maintaining overall system coherence through standardized inter-server communication protocols

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If owner certificates from different issue sources are compared directly, then key copying between terminals can be enabled, but personal information may leak and be specified

Engineering Contradiction:

Improveprivate key copying between terminalsVSAvoidpersonal information leakage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a mediation mechanism where certificate issue servers exchange verification results through standardized protocols rather than directly comparing personal information. The servers act as intermediaries that validate owner identity without exposing sensitive personal data, enabling secure key copying while preventing information leakage

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system extracts and separates the verification logic from personal information storage. Certificate issue servers extract only the necessary verification tokens and exchange them through secure protocols, leaving personal information stored locally and protected. This extraction approach enables verification functionality while removing the risk of personal information exposure

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If different certificate issue servers issue owner certificates to terminals, then various terminal types can be supported, but it becomes difficult to confirm owners are the same across servers

Engineering Contradiction:

Improvesupport for multiple terminal typesVSAvoidowner identity verification across servers

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent transforms the verification problem by changing the parameter being exchanged between servers. Instead of comparing personal information directly, servers exchange verification tokens and cryptographic proofs that represent owner identity. This parameter transformation maintains verification reliability while supporting multiple terminal types through standardized protocols

Inventive Principle:

Principle #35Parameter changes

AI summary

A terminal A transmits an owner identity confirmation start request to a terminal B including owner server association information capable of identifying an owner of the terminal and a terminal management server A of the terminal. The terminal B transmits an owner identity confirmation request to the terminal management server B of the terminal, the owner identity confirmation request including the owner server association information received and the owner server association information including information of the terminal B. The terminal management server B transmits, to the terminal management server A, an inter-server owner identity confirmation request including the identity confirmation information of the owner of the terminal B and the owner server association information of the terminal A. The terminal management server A compares the identity confirmation information of the owner of the terminal A with the identity confirmation information received, and confirms the owner identity of the two terminals.
