Blockchain Timestamped Copyright ID Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in identifying and protecting copyrighted content, especially when only a portion of the content is used by unauthorized users, as it becomes difficult to determine if the used portion is part of a copyrighted work.
Innovation Solution
The solution involves generating a timestamp and a unique identifier based on copyright information associated with textual content, which is then embedded in the content, allowing retrieval of copyright information from a blockchain using the unique identifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If copyright information is embedded in the content, then identification of copyrighted material is improved, but visual integrity and content quality may deteriorate
Solution Approach 1:
The patent applies local quality by embedding copyright information only in specific, imperceptible regions of the content rather than throughout the entire work. The embedding location is strategically chosen to maintain overall visual integrity while enabling identification. This localized approach ensures that the copyright marker does not degrade the aesthetic or functional quality of the main content.
Solution Approach 2:
The patent utilizes subtle color or luminance changes to embed copyright information that are imperceptible to human observers but detectable by machine. By modifying pixel values or color channels in ways that are visually invisible, the system achieves accurate identification without compromising the visual integrity of the original content.
2Reliability
If timestamp and unique ID are embedded in content, then copyright authentication is improved, but content complexity and processing requirements increase
Solution Approach 1:
The patent applies preliminary action by embedding the timestamp and unique ID into the content at the moment of creation or distribution, rather than adding them later during authentication. This pre-embedding approach ensures that the authentication data is already integrated into the content structure, reducing the complexity of authentication processing while maintaining high reliability.
Solution Approach 2:
The patent uses cryptographic hashing to create a unique ID that is a compact representation of the content's digital fingerprint. This copied hash value serves as a reliable authentication marker without requiring storage or processing of the entire original content, thereby reducing computational complexity while maintaining authentication reliability.
3Shape
If copyright information is embedded imperceptibly, then visual integrity is maintained, but detection and extraction difficulty increases
Solution Approach 1:
The patent implements feedback mechanisms where the embedded copyright information contains self-identifying markers or checksums that enable automated detection systems to locate and verify the embedded data. This feedback loop allows extraction tools to efficiently search for and retrieve the imperceptible copyright markers without requiring complex manual analysis, thus reducing detection difficulty while maintaining visual integrity.

AI summary
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for identifying copyrighted material based on embedded copyright information. One of the methods includes generating, by a computing device, a timestamp indicating a time at which an update to a text segment within the textual content is performed to provide an updated text segment; generating, by the computing device, a unique identifier (ID) based on the timestamp and copyright information associated with the textual content, wherein the timestamp, the textual content, the updated text segment, and the copyright information are recorded on a blockchain of a blockchain network; and embedding, by the computing device, the unique ID in at least a portion of the updated text segment to provide an information-embedded updated text segment that enables retrieval of the copyright information associated with the updated text segment from the blockchain based on the unique ID.
