Solution Overview

Problem

Current technologies lack a structured method for evaluators to acquire and evaluate target data maintained on a network, leading to potential inconsistencies and illegitimate evaluation results.

Innovation Solution

An information processing apparatus and method that utilizes blockchain data circulated on a peer-to-peer network to securely acquire and evaluate target data, ensuring data integrity and allowing evaluators to assess evaluation targets based on predefined criteria.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If target data is maintained on a network for evaluation, then evaluators can access and evaluate the evaluation target by their own criteria, but there is no structured method for evaluators to acquire and evaluate the target data, leading to potential inconsistencies and illegitimate evaluation results

Engineering Contradiction:
Improveevaluators ability to use own criteriaVSAvoidevaluation result legitimacy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system segments the evaluation process into distinct components: target data management (maintaining evaluation target data on the network), data acquisition (evaluators acquiring data via the acquisition unit), and evaluation execution (evaluators evaluating by their own criteria through the evaluation unit). This segmentation provides structure to the previously unstructured process while preserving evaluator independence.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary information processing apparatus that mediates between the target data storage and evaluator access. This apparatus with its acquisition unit and evaluation unit serves as a structured interface, allowing evaluators to access and evaluate data systematically rather than directly, ensuring legitimacy while maintaining adaptability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If each evaluator evaluates by their own criterion, then evaluation versatility is improved, but data integrity and confidentiality may be compromised without proper structural safeguards

Engineering Contradiction:
Improvecriterion diversityVSAvoiddata integrity risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by establishing the information processing apparatus with acquisition and evaluation units before the actual evaluation process begins. This pre-structured framework ensures data integrity and confidentiality are built into the system architecture beforehand, preventing potential harm while allowing diverse evaluation criteria.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If target data is made accessible on the network, then evaluation accessibility is improved, but data security and confidentiality may be weakened without proper structural protection

Engineering Contradiction:
Improvedata accessibilityVSAvoiddata confidentiality risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The information processing apparatus acts as an intermediary between the networked target data and evaluators. The acquisition unit provides controlled access to data while the evaluation unit ensures confidential processing, maintaining both accessibility and security through this mediating structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system applies different quality characteristics to different parts of the data flow: the acquisition unit handles data retrieval with accessibility in mind, while the evaluation unit processes data with confidentiality and integrity as primary qualities. This local differentiation of security properties allows both accessibility and protection.

Inventive Principle:
Principle #3Local quality
