Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods struggle to directly confirm the reliability of posts on the Internet, leading to insufficient verification of information accuracy, particularly in the presence of disinformation.

Innovation Solution

An information processing system that receives and stores property information indicating the reliability of posts, along with digital signatures, allowing viewers to determine reliability by referencing associated information stored in a graph structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If property information and digital signatures are stored for each post to verify reliability, then information accuracy is improved, but system complexity increases

Engineering Contradiction:

Improvepost reliability verificationVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a property information management system that acts as an intermediary between posts and viewers. This system stores and manages property information (reliability data) and digital signatures separately from the posts themselves, providing a mediation layer that verifies post reliability without directly complicating the post structure or viewer interaction

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a separate copy of reliability information in the form of property information records that are stored independently from the original posts. These copied property information records can be retrieved and verified without modifying or accessing the original post data, thus verifying reliability while maintaining system simplicity

Inventive Principle:

Principle #26Copying

2Loss of time

If property information is stored in a structured format with identification information, then information retrieval efficiency is improved, but data storage complexity increases

Engineering Contradiction:

Improveinformation retrieval timeVSAvoiddata storage structure

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent segments property information into distinct components including identification information, reliability data, and digital signatures. Each component is stored as a separate field in a structured format, allowing efficient retrieval of specific information (such as verifying a digital signature or checking reliability) without needing to process the entire data set

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary organization of property information by storing it in a pre-structured format with proper indexing and identification information before retrieval is needed. This advance structuring enables fast lookup and verification operations when posts are viewed, eliminating the need for complex processing at retrieval time

Inventive Principle:

Principle #10Preliminary action

AI summary

A non-transitory computer-readable storage medium storing therein an information management program for causing a computer to execute a process comprises: receiving property information indicating a reliability of a post uploaded on the Internet and a digital signature generated from the property information; and storing the property information, to which identification information of the post and the digital signature are added, in a storage.
