Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods, such as those disclosed in Patent Literature 1, cannot effectively address the demand for sharing information about communication infrastructures used in services, particularly in scenarios involving 5G networks and drones, where issues of responsibility and compensation arise.

Innovation Solution

An information processing apparatus and method that acquire log information from communication infrastructures forming an end-to-end communication path and generate transaction data incorporating this log information, which is then added to a blockchain updated using a predetermined consensus algorithm.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If log information is stored in a centralized server managed by a telecommunications carrier, then information can be collected and managed, but information sharing among multiple service providers and responsibility demarcation becomes difficult

Engineering Contradiction:

Improvelog information managementVSAvoidinformation sharing capability

Core Design Contradiction:

Loss of informationVSAdaptability or versatility

Solution Approach 1:

The patent segments the centralized log information management into distributed blockchain nodes. Each node in the end-to-end communication path (telecommunications carrier, apparatus manufacturer, service provider) maintains its own log information independently on the blockchain, eliminating the single centralized server model and enabling autonomous information management while ensuring shareability across all participants.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The blockchain acts as an intermediary layer between different service providers and the telecommunications carrier. It provides a neutral, shared ledger that all parties can access and verify, enabling transparent information sharing and objective responsibility demarcation without requiring trust in any single centralized authority.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If traditional centralized log management is used, then information collection is simple, but responsibility demarcation and issue identification in end-to-end communication paths become difficult

Engineering Contradiction:

Improvelog collection simplicityVSAvoidresponsibility demarcation difficulty

Core Design Contradiction:

Ease of manufactureVSDifficulty of detecting and measuring

Solution Approach 1:

The patent divides the end-to-end communication path into discrete segments, with each segment (telecommunications carrier, apparatus manufacturer, service provider) recording its own log information in separate blockchain blocks. This segmentation enables clear identification of which segment generated which log entry, making responsibility demarcation straightforward while maintaining automated collection simplicity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The blockchain structure provides automatic feedback mechanisms where each node can verify the integrity and origin of log information from other nodes. The immutable ledger and consensus algorithm ensure that log information can be traced back to its source, providing automatic feedback for responsibility identification without increasing collection complexity.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If multiple parties manage log information independently, then responsibility can be demarcated, but information consistency and trust verification become problematic

Engineering Contradiction:

Improveresponsibility demarcation capabilityVSAvoidinformation consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges the independent log information systems of multiple parties into a unified blockchain ledger. While each party independently generates and submits its own log information, the blockchain consensus mechanism ensures that all parties see the same consistent state of the ledger, combining individual autonomy with collective consistency and trust verification.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The blockchain consensus algorithm provides continuous feedback to all nodes about the state of the ledger and the validity of new log information. This automatic feedback mechanism ensures that any inconsistencies are detected and resolved through consensus, maintaining information reliability while allowing independent responsibility demarcation.

Inventive Principle:

Principle #23Feedback

AI summary

Provided is a technique that allows persons concerned with provision of a service to share information pertaining to a communication infrastructure which has been used to provide the service. An information processing apparatus includes: an acquisition means that acquires log information of one or more communication infrastructures which constitute an end-to-end communication path; and a generation means that generates transaction data which includes the log information and which is to be added to a block chain updated using a predetermined consensus algorithm.
