Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NFT marketplaces face challenges in managing digital assets securely and addressing copyright concerns, with centralized storage risking data loss and decentralized storage incurring high costs and processing demands, and conventional systems failing to enforce digital rights management effectively.
Innovation Solution
A system using trusted ledgers, such as blockchain, to securely store metadata and digital assets, integrating DRM technology to manage access rights and enforce business conditions, ensuring secure and efficient NFT transactions and asset management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If metadata is stored on a centralized server, then the system is easier to implement and update, but the system becomes vulnerable to data loss and server failures
Solution Approach 1:
The patent segments the storage system into two parts: the actual digital asset stored on the decentralized network and the metadata stored on a centralized server. This allows the system to benefit from both centralized ease of implementation and decentralized reliability, as the critical asset data is distributed while metadata management remains centralized.
Solution Approach 2:
The patent introduces a decentralized network as an intermediary between the centralized server and the digital asset. The network stores cryptographic hashes and references to the actual asset files, creating a reliable bridge that ensures data availability without requiring the server to directly host the assets.
2Reliability
If metadata is stored on a decentralized ledger, then data reliability improves, but system complexity and processing demands increase
Solution Approach 1:
The patent segments the data into two categories with different storage locations: large digital assets are stored on the decentralized network while smaller metadata are stored on the centralized server. This segmentation allows the system to achieve decentralized reliability for critical data without the full complexity of storing everything on-chain.
Solution Approach 2:
The patent uses cryptographic hashes as copies or references of the actual asset data. Instead of storing the full asset on the decentralized ledger, the system stores hashes that point to the actual files stored elsewhere on the network, reducing complexity while maintaining reliability through verification.
3Adaptability or versatility
If NFTs do not have DRM protection, then access is more flexible, but copyright rights cannot be enforced
Solution Approach 1:
The patent implements dynamic DRM policies that can change based on the user's access rights. The system allows flexible access control where the same NFT can have different usage rights for different users, enabling adaptability while maintaining copyright protection through programmable access conditions.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors and enforces DRM policies. When a user attempts to access or transfer an NFT, the system checks the associated metadata and cryptographic proofs to verify copyright rights, providing feedback that prevents unauthorized actions while allowing legitimate use.
4Ease of operation
If NFTs allow free copying and redistribution, then user freedom increases, but digital rights management becomes ineffective
Solution Approach 1:
The patent implements dynamic access control where user freedom is not absolute but conditioned on their rights. The system provides freedom within boundaries, allowing users to access and use NFTs according to their purchased rights while preventing copying and redistribution that would violate copyright protection.
Solution Approach 2:
The system uses feedback mechanisms to monitor NFT transactions and access patterns. When a user attempts to copy or redistribute an NFT beyond their authorized rights, the system detects this through cryptographic verification and blocks the action, maintaining rights protection while allowing legitimate user operations.
