Information Processing System for Hash-Based Citation Verification

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The proliferation of fake information, particularly in the context of satellite data and reports, makes it difficult to verify the accuracy and credibility of information, especially when such data is transcribed into creations like reports.

Innovation Solution

An information processing system that detects the transcription of citation information, stores evidence information indicating the evidence of this transcription, and uses hash values to verify the authenticity of the information, with the option to store this evidence in a blockchain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If citation information is transcribed into creations without verification, then information processing efficiency is improved, but information authenticity deteriorates

Engineering Contradiction:

Improveinformation processing efficiencyVSAvoidinformation authenticity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary actions by detecting transcription of citation information and generating hash values before the creation is finalized or published. This advance verification ensures authenticity is established upfront, allowing efficient processing later without compromising reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms by storing hash values of citation information and comparing them against transcribed content in creations. This closed-loop verification provides continuous feedback on information authenticity, enabling efficient processing while maintaining reliable verification.

Inventive Principle:

Principle #23Feedback

2Reliability

If hash value verification is performed for all citation information, then information authenticity is improved, but processing time increases

Engineering Contradiction:

Improveinformation authenticityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system applies partial verification by focusing hash value comparison only on transcribed citation information that is detected through transcription detection. Rather than verifying all information uniformly, it selectively verifies only the relevant transcribed portions, reducing processing time while maintaining authenticity where needed.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If evidence information is stored for every transcription, then information credibility is improved, but storage requirements increase

Engineering Contradiction:

Improveinformation credibilityVSAvoidstorage requirements

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system uses hash values as compact digital copies or fingerprints of the original citation information. Instead of storing entire copies of cited materials, it stores only the hash values which serve as verified evidence, dramatically reducing storage requirements while maintaining credibility through verifiable cryptographic proof.

Inventive Principle:

Principle #26Copying

AI summary

An information processing system detects a transcription of citation information to a creation, and stores evidence information indicating an evidence of the citation information in a case where the transcription is detected.
