Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional media verification methods are used, then the verification process is simple and fast, but the system is vulnerable to manipulation and fraud

Engineering Contradiction:
Improveverification securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces blockchain technology as an intermediary layer between media publishers and consumers. The blockchain ledger serves as a neutral, decentralized mediator that stores cryptographic hashes of media content, enabling verification without requiring trust in any single party. This resolves the contradiction by providing high reliability through the blockchain's immutable nature while maintaining operational simplicity through automated hash comparison processes.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional centralized verification mechanisms with a cryptographic system based on hash functions and blockchain technology. Instead of relying on centralized authorities or manual verification processes, the system uses mathematical cryptography to ensure content authenticity. This substitution provides enhanced security and reliability while automating the verification process, thereby not increasing operational complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If blockchain technology is implemented for media verification, then tamper-proof authentication is achieved, but system complexity and implementation difficulty increase

Engineering Contradiction:
Improveauthentication integrityVSAvoidsystem implementation ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent implements preliminary action by having media publishers register their content hashes on the blockchain before distribution. This pre-registration creates an immutable record of authentic content that can be quickly verified later without complex real-time analysis. The verification process simply compares the hash of received content against the pre-stored blockchain record, significantly simplifying the actual verification operation despite the underlying blockchain complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses cryptographic hashing to create a digital fingerprint (copy) of the media content that is stored on the blockchain. Instead of storing or transmitting the actual media files through the blockchain system, only the compact hash values are recorded. This copying approach maintains authentication integrity while minimizing system complexity, as hash comparison is computationally simple compared to verifying entire media files.

Inventive Principle:
Principle #26Copying

3Measurement precision

If media content is registered on blockchain with unique fingerprints, then verification accuracy is improved, but processing time and computational resources increase

Engineering Contradiction:
Improvecontent verification accuracyVSAvoidverification processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent employs cryptographic hashing to create a compact digital representation of media content that can be rapidly computed and compared. Instead of analyzing entire video or audio files during verification, the system only needs to compute and compare hash values, which are small fixed-size strings. This copying approach maintains high verification accuracy by detecting any content modification while dramatically reducing processing time and computational resource requirements.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent transforms the media content into a different parameter space by converting it into a cryptographic hash value. This parameter transformation changes the verification task from analyzing complex multimedia data to comparing simple hexadecimal strings. The transformation maintains verification accuracy (any content change produces a completely different hash) while reducing processing time, as hash computation and comparison are computationally efficient operations.

Inventive Principle:
Principle #35Parameter changes

AI summary

Publishers can securely register media content (e.g. video, audio, image etc.) by verifying their identity, for example, through a blockchain wallet or other verification mechanism, providing media metadata, and generating a unique fingerprint and hash of the media. The unique fingerprint hash, along with basic metadata such as the URL location or a unique identifier of the media, is stored on the blockchain to link the media to its publisher.
