Solution Overview

Problem

Users face challenges in verifying the accuracy and trustworthiness of digital content provided by content providers, as existing methods lack independence, openness, and resistance to modification.

Innovation Solution

Implementing a blockchain-based content validation system where content validation nodes receive data from content providers, validate content using validation information stored on a blockchain, and store results as transactions, enabling transparent and secure validation processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional content verification methods are used, then verification can be performed, but the verification lacks independence, openness, and resistance to modification

Engineering Contradiction:

Improvetrustworthiness of content verificationVSAvoidcomplexity of verification system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a blockchain-based intermediary system that mediates between content providers and users. The blockchain stores content hashes and verification data in a decentralized, immutable manner, providing an independent third-party verification mechanism that enhances trustworthiness without requiring direct trust between content providers and users.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional centralized verification mechanisms with a cryptographic-based blockchain system. Instead of relying on centralized authorities or manual verification processes, the system uses hash functions, digital signatures, and consensus algorithms to automatically verify content integrity and authenticity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If manual verification methods are used, then verification can be performed, but the process is slow and consumes significant computing resources

Engineering Contradiction:

Improvespeed of content validationVSAvoidcomputing resources consumed

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The patent implements preliminary hashing of content at the source (content provider side) before distribution. The content hash is stored on the blockchain in advance, enabling users to quickly verify content integrity by comparing the hash of received content against the stored hash, eliminating the need for resource-intensive re-verification of the entire content.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts only the essential verification data (content hashes, timestamps, verification results) from the full content and stores it on the blockchain. This allows for lightweight verification operations that consume minimal computing resources while maintaining verification effectiveness.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A device may receive content data from a content provider, the content data including: data identifying content, and data for verifying that the content has not changed. The device may access a blockchain associated with the content data, the blockchain including validation information specifying instructions for validating the content. In addition, the device may perform, based on the validation information, validation of the content to determine a measure of confidence that the content is accurate and store results of the validation in the blockchain as a transaction. Based on the validation results, the device may perform an action.
