Blockchain Digital Rights Management System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital rights management (DRM) technologies lack transparency and security due to reliance on content distributors, making copyright management untrusted and vulnerable to tampering.
Innovation Solution
A blockchain-based digital content copyright management system that uses a P2P network to ensure the correctness and legality of copyright processing operations by constructing and storing copyright management transactions on a blockchain, making them immutable and transparent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional DRM system controlled by content distributor is used, then copyright management can be centralized and controlled, but the system lacks transparency and security, making it vulnerable to tampering
Solution Approach 1:
The patent segments the centralized DRM system into multiple independent blockchain nodes distributed across the network. Each node maintains its own copy of the copyright management data and independently verifies transactions, eliminating the single point of control and potential tampering while maintaining system functionality through distributed consensus mechanisms.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between content distributors and users. This blockchain intermediary provides transparent and tamper-proof recording of copyright transactions, ensuring that no single party (including content distributors) can unilaterally manipulate copyright management data without network consensus.
2Reliability
If centralized DRM system is used, then copyright authorization can be controlled by distributor, but the system lacks transparency making copyright management untrusted
Solution Approach 1:
The patent implements feedback mechanisms where all blockchain nodes continuously verify and validate copyright transactions. Each transaction is broadcast to the network, verified by multiple nodes, and only committed when consensus is reached. This feedback loop ensures transparency and trustworthiness while maintaining operational simplicity through automated consensus protocols.
3Reliability
If conventional DRM system is used, then copyright control can be centralized, but the system is vulnerable to data tampering by distributors
Solution Approach 1:
The patent applies preliminary actions by pre-distributing identical copies of the copyright management system to multiple network nodes before any copyright transactions occur. Each node is pre-configured with the same blockchain data and verification capabilities, enabling them to independently verify transactions and prevent tampering from the outset rather than relying on post-hoc detection.

AI summary
A digital content copyright management method includes: receiving a copyright processing request, and constructing a copyright management transaction according to the copyright processing request; and storing the copyright management transaction in a blockchain for processing, where the blockchain is stored in all blockchain apparatuses. Trusted and secure processing of the copyright management transaction can be implemented.
