Blockchain Content Contract System for Copyright Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in establishing and managing copyright agreements, particularly when personal content is used by third parties, leading to inhibited content distribution and cumbersome procedures.
Innovation Solution
A content contract system utilizing a distributed ledger like blockchain, which includes a right holder terminal, an assignee terminal, a control terminal, and a content accumulation server, connected via a P2P network. This system uses smart contracts to distribute and manage rights to content data, enabling transparent and efficient transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a distributed ledger like blockchain is used to manage copyright agreements, then transparency and efficiency in right processing are improved, but the complexity of the system increases
Solution Approach 1:
The system segments the copyright management process into distinct functional modules: right holder terminal for uploading content and issuing tokens, assignee terminal for applying and receiving rights, control terminal for verifying transactions, and content accumulation server for storing content. Each terminal runs specific software components that handle particular tasks, reducing overall system complexity while maintaining transparency through distributed ledger technology.
Solution Approach 2:
The control terminal acts as an intermediary that verifies transactions between right holders and assignees. It validates token issuance, application submissions, and right transfer requests before recording them on the distributed ledger. This intermediary layer simplifies the system by centralizing verification logic while maintaining the decentralized benefits of blockchain technology.
2Productivity
If traditional copyright agreement procedures are used, then the system is simpler to implement, but the distribution of content rights becomes cumbersome and inefficient
Solution Approach 1:
The system enables self-service through automated smart contracts that execute copyright agreements without manual intervention. When an assignee's application is verified, the control terminal automatically transfers rights and updates the distributed ledger. Token issuance and right management occur autonomously based on predefined rules, eliminating cumbersome manual procedures and significantly improving distribution efficiency.
Solution Approach 2:
The system transforms copyright rights into digital tokens with specific parameters stored on the distributed ledger. Each token contains information about the content, right holder, assignee, and type of right. This parameter-based representation simplifies right management by converting complex legal concepts into structured data that can be automatically processed and transferred, improving productivity while maintaining procedural simplicity.
3Loss of time
If manual right processing procedures are used, then the procedure is easier to understand, but the time required for copyright establishment increases
Solution Approach 1:
The system performs preliminary actions by pre-defining smart contract logic and token structures before actual copyright transactions occur. Right holders upload content and configure agreement terms in advance, creating templates that automatically execute when assignees apply. This preliminary setup reduces the time required for actual copyright establishment while maintaining procedural clarity through standardized, pre-approved agreement frameworks.
Solution Approach 2:
The system replaces manual mechanical procedures with automated digital processes. Instead of physical document signing and manual record-keeping, the distributed ledger automatically records right transfers, and smart contracts execute agreements. This substitution dramatically reduces the time for copyright establishment while maintaining ease of operation through user-friendly interfaces that guide users through standardized processes.

AI summary
A blockchain is used to distribute a right to content data. A right holder terminal, an assignee terminal, and a blockchain control terminal stores a blockchain that is synchronized among the right holder terminal, the assignee terminal, and the blockchain control terminal. The blockchain includes a transaction set with a smart contract program for distributing the right. The blockchain control terminal includes a token issuance unit generating token data that includes match information for the content data and a type of right to be distributed, is set with an address of a right holder as owner information, and is identified by a token identifier, and registering the token data corresponding to the token identifier with the blockchain.
