Solution Overview

Problem

Decentralized networks in information management systems become siloed when connected cooperatively, increasing the risk of information leakage and security breaches due to increased information sharing.

Innovation Solution

An authentication system using non-fungible tokens (NFTs) to authenticate nodes in decentralized networks, allowing secure communication without direct information exchange, leveraging blockchain ledgers for secure storage and authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If decentralized networks are connected cooperatively to improve interoperability, then user convenience is enhanced, but security risk increases due to information sharing

Engineering Contradiction:

ImproveinteroperabilityVSAvoidsecurity risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an authentication system as an intermediary layer between decentralized networks. This system uses authentication information (such as biometric data) and issue-specific information stored in secure elements to verify user identity before allowing information sharing. The authentication system acts as a mediator that enables cooperative connection while preventing unauthorized access, thus resolving the contradiction between interoperability and security.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If information about user is shared among networks for cooperative connection, then interoperability is improved, but risk of information leakage increases

Engineering Contradiction:

Improvecooperative connectionVSAvoidinformation leakage

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent segments user information into different types and stores them in separate secure elements within the authentication system. Different authentication information (e.g., fingerprint, facial recognition) and issue-specific information are kept separate. This segmentation allows selective sharing of only necessary information for each cooperative connection, preventing unauthorized access to complete user profiles and thus reducing information leakage risk while maintaining interoperability.

Inventive Principle:

Principle #1Segmentation

AI summary

In the authentication system, a first wallet of a first decentralized ledger shared by a plurality of first nodes accessible to first information about a user includes a URI of first information, and first specification information for specifying a second wallet of a second decentralized ledger shared by a plurality of second nodes accessible to second information about user, and second wallet includes a URI of second information and second specification information for specifying first wallet. First and second specification information are stored as tokens having non-fungibility, respectively. Second node, in response to a request from a user terminal, requests first node to authenticate second node for user, by using second specification information. The first node, in response to a request from a control part of the user terminal, requests the second node to authenticate the first node for the user, by using the first specification information.
