Server NFT Locking for Temporary Vehicle Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of non-fungible tokens (NFTs) as certificates for temporary access to tangible objects leads to malfunctions where the token can be transferred during use, causing unauthorized access or denial of access to the object.
Innovation Solution
A server system that locks the NFT upon a temporary use request, prohibiting its transfer until the use is completed, ensuring the NFT holder's permission is maintained throughout the temporary use period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the NFT is made transferable to allow free trading, then the liquidity and marketability of the token are improved, but the risk of unauthorized transfer during temporary use increases
Solution Approach 1:
The NFT's transferability status is made dynamic rather than static. The token can be transferred during periods when it is not in use, but automatically becomes non-transferable when a temporary use request is approved. This dynamic state change allows the system to balance market liquidity with authorization control, resolving the contradiction between transferability and reliability.
Solution Approach 2:
The system implements feedback mechanisms where the server continuously monitors the usage state of the NFT and adjusts its transferability accordingly. When the NFT is assigned for temporary use, the server receives feedback about this state change and automatically prevents further transfers. This feedback loop ensures that the NFT's transferability is always consistent with its current usage status, maintaining both market functionality and authorization integrity.
2Ease of operation
If the NFT remains transferable during temporary use, then the holder can trade the token freely, but unauthorized users may gain access or legitimate users may be denied access
Solution Approach 1:
The server performs preliminary actions by locking the NFT's transferability before the temporary use period begins. When a temporary use request is submitted and approved, the server proactively sets the NFT to a non-transferable state in advance, preventing any potential unauthorized transfers before they can occur. This preliminary action eliminates the window of vulnerability where both trading and unauthorized access could happen.
Solution Approach 2:
The server acts as an intermediary between the NFT holder's trading desires and the temporary use authorization requirements. It mediates by automatically managing the transferability status based on usage state, removing the need for manual intervention while ensuring that trading freedom is maintained when appropriate and unauthorized access is prevented when required.
3Reliability
If the NFT is locked to prevent transfer during use, then authorization control is improved, but the holder cannot trade the token even after use is completed
Solution Approach 1:
The NFT's transferability is controlled through periodic state changes rather than a continuous locked state. The token transitions between transferable and non-transferable states based on discrete events: becoming non-transferable when temporary use begins and returning to transferable status when use is completed. This periodic action ensures authorization control is maintained only during the necessary period, eliminating unnecessary trading delays.
Solution Approach 2:
The system implements self-service by automatically managing the NFT's transferability status without requiring manual intervention from the holder. When the temporary use period ends, the server automatically reinstates transferability, eliminating the need for the holder to manually unlock the token and reducing trading delays caused by administrative overhead.

AI summary
An entity server includes a communication apparatus and a processor. The communication apparatus is configured to receive a temporary use request that requests temporary use of a vehicle by a user, the vehicle being associated with an NFT. When the communication apparatus receives the temporary use request, the processor performs locking processing for locking the NFT.
