Decentralized Copyright Detection via Blockchain Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing copyright rights defense systems based on content feature detection have limited coverage due to a centralized architecture, making it difficult to detect infringement acts by illegal content distributors and reducing detection rates and effectiveness.
Innovation Solution
A decentralized system using blockchain technology for copyright rights defense detection, where rights defense detection service apparatuses can query feature metadata and license information from distributed blockchains, allowing for detection across all content distributors, improving detection efficiency and coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a centralized copyright rights defense system is used, then the system architecture is simple and easy to manage, but the coverage range of distribution channel is limited and detection rate is reduced
Solution Approach 1:
The patent divides the centralized copyright rights defense system into multiple distributed detection nodes that operate independently across different distribution channels. Each node performs local feature extraction and matching, eliminating the single-point bottleneck while maintaining system functionality through distributed architecture.
Solution Approach 2:
The patent introduces a blockchain-based intermediary layer that mediates between content distributors and the copyright protection system. This intermediary enables decentralized verification of content features and infringement detection without requiring direct integration with a centralized system, thereby expanding coverage to illegal distributors.
2Ease of operation
If a centralized copyright rights defense system is used, then the system is easy to deploy and manage, but the detection effect for illegal content distributors is reduced
Solution Approach 1:
The patent enables detection nodes to autonomously perform feature extraction, database querying, and infringement determination without centralized coordination. Each node independently verifies content features against the blockchain-stored reference features, allowing the system to detect infringements from illegal distributors without requiring their cooperation or system deployment on their platforms.
3Reliability
If content feature collection is limited to cooperative distribution channels, then the system maintains security and control, but the detection rate and detection effect are reduced
Solution Approach 1:
The patent introduces a blockchain-based intermediary that enables secure, trustless interaction between the copyright protection system and any content distributor, including illegal ones. The blockchain stores immutable reference features and licensing information, allowing the system to verify content provenance and detect infringements without compromising security or requiring cooperation from distributors.

AI summary
A method, an apparatus, and a system for copyright rights defense detection are provided. The method includes: sending a metadata query request to a copyright handling apparatus; receiving a metadata query response that is sent by the copyright handling apparatus and that includes feature metadata, where the feature metadata is obtained by the copyright handling apparatus based on a detection task transaction identifier from a blockchain stored in a blockchain processing apparatus; obtaining a rights-to-be-defended content feature corresponding to the feature metadata from a feature database; sending a license query request to a license processing apparatus; receiving a license query response that is sent by the license processing apparatus and that includes license information, where the license information is obtained by the license processing apparatus based on the detection task transaction identifier from a blockchain stored in a blockchain processing apparatus; and performing rights defense detection for a copyright based on the obtained rights-to-be-defended content feature and the license information. Rights defense detection can be performed for a copyright by any rights defense detection service apparatus.
