NFT-Based Access Control for Virtual Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for managing access to virtual spaces lack effective authorization mechanisms, particularly in metaverse applications, where ensuring users have the necessary non-fungible tokens (NFTs) to access specific areas and services is inefficient and insecure.
Innovation Solution
A method utilizing a processor connected to a blockchain network that obtains access requests from users, verifies their NFT ownership by comparing token information, and transmits responses to grant or deny access to virtual space areas, incorporating authentication tokens and submission certificates to secure the authorization process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional access management techniques are used for virtual spaces, then the system is simpler to implement, but security and authorization reliability are insufficient
Solution Approach 1:
The patent introduces NFTs as intermediary objects that mediate between users and virtual space areas. The NFT serves as a verifiable credential that proves authorization without requiring complex direct verification systems. The processor verifies access rights by checking NFT ownership and properties rather than implementing complex authorization logic, thus improving security while managing complexity through the intermediary NFT mechanism.
Solution Approach 2:
The system performs preliminary verification of NFT ownership and properties before granting access to virtual space areas. The processor obtains access requests, verifies the user's NFT credentials in advance, and only then allows entry. This preliminary action ensures security is established before access is granted, resolving the contradiction between reliability and complexity by front-loading the verification process.
2Reliability
If NFT verification processes are implemented for all virtual space areas, then access security is improved, but processing time and operational complexity increase
Solution Approach 1:
The patent implements partial verification by checking only the necessary NFT properties required for each specific area access. Rather than verifying all possible NFT attributes universally, the system performs targeted verification based on the specific area's requirements. This selective approach maintains security while reducing verification time and processing overhead.
Solution Approach 2:
The system uses NFT metadata and properties as verifiable copies of authorization credentials. Instead of complex real-time verification of ownership chains, the processor verifies against the NFT's stored properties and metadata that serve as cryptographic proofs. This copying mechanism accelerates verification while maintaining security through blockchain-verified data integrity.
3Measurement precision
If detailed NFT information verification is performed, then authorization accuracy is improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent applies local quality by verifying only the specific NFT properties relevant to each area's access requirements. Different areas have different property requirements, and the system checks only those local properties needed for each specific access request rather than all NFT properties universally. This targeted verification approach maintains high authorization accuracy while reducing overall system complexity.
Solution Approach 2:
The verification process is segmented into distinct steps: obtaining the access request, retrieving NFT information, verifying specific properties, and granting access. Each segment handles a specific aspect of verification, making the complex process manageable and efficient. The segmentation allows the system to maintain high accuracy through thorough verification while organizing complexity into manageable discrete operations.

AI summary
A method includes obtaining, from a terminal operated by a user, by a processor connected with a computer network including a blockchain service, an access request to request access to an area of a virtual space including multiple areas; based on the access request, obtaining, by the processor, first information including non-fungible token information, the first information configured to be used to determine whether the user is authorized to access the area of the virtual space; verifying, by the processor, based on the first information, an access right of whether the area of the virtual space is accessible to the user by determining whether a non-fungible token is owned by the user and by determining whether the non-fungible token satisfies the non-fungible token information of the first information; and based on a result of the verifying, transmitting to the terminal, by the processor, a response to the access request.
