Digital Watermarking and Blockchain for Copyright Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing copyright protection methods face challenges in identifying and managing unauthorized use of copyrighted content, particularly when only a portion of the content is used, as it can be difficult to trace the origin and ownership of the copyrighted material.
Innovation Solution
Generating a unique identifier based on copyright information associated with digital content, embedding it in blank pages of an electronic file by altering attributes, and distributing these pages to a blockchain network for secure storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If copyright information is embedded in electronic files using digital watermarking, then copyright identification capability is improved, but detection difficulty increases when only partial content is used
Solution Approach 1:
The patent divides the copyright identification system into two parts: (1) embedding a unique identifier in the entire electronic file using digital watermarking, and (2) recording file information (hash value, filename, extension) in a blockchain ledger. This segmentation allows efficient detection by querying blockchain for file information and verifying the unique identifier, solving the problem of detecting partial content usage.
Solution Approach 2:
The patent introduces a blockchain ledger as an intermediary between the digital watermarking system and the detection system. The blockchain stores metadata (hash values, filenames, extensions) that mediates the detection process, allowing users to query file information and verify copyright without directly analyzing the watermarked content, thus reducing detection difficulty.
2Reliability
If distributed ledger technology is used to store copyright information, then security and immutability are improved, but system complexity increases
Solution Approach 1:
The patent extracts only essential copyright metadata (hash values, filenames, extensions, unique identifiers) and stores them in the blockchain ledger, while keeping the actual copyright protection mechanism (digital watermarking) in the electronic files themselves. This extraction reduces system complexity by minimizing blockchain storage requirements and simplifying the interaction between components.
3Measurement precision
If unique identifiers are embedded in all electronic files, then copyright tracing capability is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary actions by automatically embedding unique identifiers and recording file metadata in the blockchain ledger at the time of file creation or upload. This preliminary processing enables rapid copyright tracing later, as the system already has pre-recorded file information and unique identifiers ready for verification, significantly reducing processing time during detection phases.

AI summary
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for embedding copyright information in one or more pages for presenting digital content. One of the methods includes generating, by a computing device, a unique identifier (ID) based on copyright information associated with the digital content; identifying one or more attributes associated with a page design of one or more blank pages of an electronic file; embedding the unique ID in the one or more blank pages by changing the one or more attributes to be representative of the unique ID; allocating the digital content to at least one of the one or more information-embedded pages; and distributing, by the computing device, the one or more information-embedded pages allocated with the digital content to the blockchain network.
