DNFT Metadata Server with Authority Verification Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NFTs face limitations in updating reliable metadata and have a risk of malicious data changes, lacking authority verification during updates.
Innovation Solution
A server system is implemented to manage and update dynamic non-fungible tokens (DNFTs) by determining the authority of the update requester, ensuring only authorized entities can modify metadata through a differential management system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If metadata of NFT is updated to enable dynamic content, then adaptability and functionality are improved, but reliability and security deteriorate due to lack of authority verification
Solution Approach 1:
The system performs preliminary authority verification before allowing metadata updates. The server checks whether the update requesting device has proper authorization credentials stored in the database before processing any metadata modification requests, preventing unauthorized changes in advance
Solution Approach 2:
The server acts as an intermediary between the update requesting device and the NFT metadata. It mediates the update process by verifying authority through stored credentials and only permitting updates from authenticated sources, thus maintaining data integrity while enabling dynamic content
2Reliability
If authority verification system is implemented for DNFT updates, then reliability and security are improved, but device complexity increases due to additional verification steps
Solution Approach 1:
The system uses self-service authentication where the update requesting device presents its own credentials for verification. The server checks these credentials against stored authority information, enabling automated security verification without requiring complex manual authentication processes
Solution Approach 2:
The server performs multiple functions: it stores authority credentials, verifies update requests, and manages DNFT metadata. This multi-functionality consolidates the verification system into a single platform, reducing overall system complexity while maintaining security
3Adaptability or versatility
If differential management of metadata is implemented, then functionality and adaptability are improved, but loss of information increases due to selective updates
Solution Approach 1:
The metadata is segmented into different fields that can be independently updated. The server allows selective modification of specific metadata fields based on authority verification, enabling differential updates without requiring complete metadata replacement and thus preventing information loss
Data Source
AI summary
A server according to an embodiment of the present disclosure can comprise: a communication interface configured to communicate with a user device or an update requesting device; and a controller configured to receive an update request for updating a dynamic non-fungible token (DNFT) from the update requesting device, determine whether the update requesting device has an authority for updating the DNFT, and update a metadata of the DNFT if it is determined that the update requesting device has the authority for updating the DNFT.
