Solution Overview

Problem

In systems combining distributed ledger and file storage, ensuring consistency and managing file associations across different ID systems is challenging, leading to potential single points of failure and unrealistic searches within existing decentralized and centralized ledger networks.

Innovation Solution

A registration terminal and verification terminal that connect to both decentralized and centralized distributed ledger networks, using a registration unit to generate and transmit file identifiers and signature transactions, and a verification unit to verify these transactions across both networks, ensuring robust and flexible information management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate distributed ledger and file storage systems are used together with different ID systems, then system functionality is improved, but information consistency cannot be guaranteed

Engineering Contradiction:

Improvesystem functionalityVSAvoidinformation consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a file association management contract as an intermediary layer between the distributed ledger network and file storage system. This contract manages file associations and ID mappings centrally within the ledger, mediating between different ID systems and ensuring consistent information across the heterogeneous system architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent combines the file association management functionality directly into the distributed ledger system by creating a dedicated contract. This merging of file management operations with the ledger's native data structures allows the system to maintain consistency while supporting multiple ID systems, as all file associations are recorded and managed within the same immutable ledger framework.

Inventive Principle:

Principle #5Merging (Combining)

2Measurement precision

If all tokens in infinite contracts are searched to determine legitimacy, then accuracy is improved, but processing time becomes unrealistic

Engineering Contradiction:

Improveverification accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent extracts the file association management functionality into a separate, dedicated contract within the distributed ledger. This extraction allows verification operations to focus only on the relevant file association contract rather than searching through all contracts in the system, significantly reducing verification time while maintaining accuracy by concentrating all file-related associations in one manageable location.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs preliminary organization of file associations by maintaining them in a dedicated contract from the outset. This preliminary structuring of data means that when verification is needed, the system already has all relevant information organized and accessible in the file association contract, eliminating the need for exhaustive searches through all contracts later.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If a new contract is created for file association management, then verification efficiency is improved, but single point of failure risk increases

Engineering Contradiction:

Improveverification efficiencyVSAvoidsingle point of failure

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies local quality by creating a specialized file association management contract with specific functionality tailored to file operations. This dedicated contract concentrates file association logic in one location, improving verification efficiency for file-related operations. The localized nature of this contract means that failures are contained to file management operations only, while the rest of the distributed ledger system remains operational and resilient.

Inventive Principle:

Principle #3Local quality

AI summary

A registration terminal according to the present embodiment is connectable to a first distributed ledger network and a second distributed ledger network. The registration terminal includes a registration unit, a first control unit, and a second control unit. The registration unit registers a file in an external storage service. The first control unit generates a registration transaction including a file identifier assigned to the file by the storage service and a verification key, and transmits the registration transaction to the first distributed ledger network. The second control unit generates a token transaction related to generation of a token and including a signature object message including the file identifier and a signature value obtained by digitally signing the signature object message with a signature key, and transmits the token transaction to the second distributed ledger network.
