Blockchain Content Management System for Unauthorized Use Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems using blockchain technology can verify the authenticity of digital images but fail to determine if the content has been copied and used without permission.
Innovation Solution
A management system that utilizes a blockchain to register content data with a hash value and metadata, allowing for the determination of authenticity by comparing user information with registered provision destination information, thereby identifying unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is used to register content data with hash values, then the authenticity of content data from generation time is guaranteed, but it is difficult to determine whether the content data has been copied and used without permission
Solution Approach 1:
The system performs preliminary registration of provision destination information in the blockchain when content is legitimately distributed. This advance preparation creates a reference record that enables later detection of unauthorized use by comparing current usage against the registered provision destinations.
Solution Approach 2:
The system establishes a feedback mechanism where usage information is compared against the registered provision destination information stored in the blockchain. This comparison provides feedback that identifies unauthorized copying and usage, enabling the system to detect and respond to infringement.
2Device complexity
If only hash value registration is performed in the blockchain, then the system complexity is reduced, but the ability to verify unauthorized copying is lost
Solution Approach 1:
The system merges multiple functions into the blockchain registration process: it combines content authenticity verification with copyright management by registering both hash values and provision destination information together. This integration maintains blockchain's simplicity while adding copyright protection capabilities.
Solution Approach 2:
The blockchain registration system is designed with multi-functionality, serving both as an authenticity verification mechanism and a copyright management system. By making the registration process universal, the system avoids increasing complexity while achieving both authenticity guarantee and unauthorized use detection.
Data Source
AI summary
A management system that manages content data corresponding to a hash value registered in a block of a blockchain. Content data selected by a user from among pieces of content data that are management targets, is provided to a provision destination of the selected content data. Information on the provision destination of the selected content data is registered in a block of the blockchain in association with an identification number for identifying the selected content data. When the management system receives content data that is a target of authenticity determination, an identification number for identifying the content data, and user information of the content data, authenticity of the received content data is determined. In the determination of the authenticity of the received content data, the received user information is compared with the provision destination information registered in the blockchain.
