NFT Avatar Access Control for Metaverse Premises
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In metaverse environments, existing authentication mechanisms allow avatars to freely roam and access premises without consent, leading to potential revenue loss and privacy issues for owners.
Innovation Solution
Utilizing Non-Fungible Tokens (NFTs) with encrypted metadata to secure access, where NFTs are assigned to avatars, allowing validation of access requests based on predefined access rights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional authentication mechanisms (two-factor authentication, single sign-on) are used to allow avatars to enter the metaverse, then user authentication is achieved, but the avatar can roam freely and access premises without consent, leading to loss of control over premise access
Solution Approach 1:
The patent segments access control by creating individual NFT-based access tokens for each avatar-premise pair. Each NFT contains specific metadata defining which avatar can access which premise and under what conditions. This segmentation allows fine-grained control where each avatar has a unique access token rather than general authentication, resolving the contradiction between ease of entry and controlled access.
Solution Approach 2:
The patent introduces NFTs as an intermediary between authentication and access. The NFT acts as a mediator that carries access rights information, bridging the gap between simple authentication and complex access control. The NFT contains encrypted metadata that serves as the intermediary layer verifying both identity and authorization, eliminating the need for complex post-authentication access control systems.
2Adaptability or versatility
If avatars are allowed to roam freely within the metaverse after authentication, then user mobility and exploration are improved, but owners cannot restrict avatar movement, leading to potential revenue loss and privacy issues
Solution Approach 1:
The patent makes access rights dynamic by embedding them in NFTs that can be issued, revoked, or modified by premise owners. The NFT metadata contains dynamic access conditions such as time periods, specific zones within premises, and permitted actions. This allows avatar mobility to be adaptable while maintaining reliable security control, as owners can dynamically adjust access rights without restricting exploration entirely.
Solution Approach 2:
The patent changes the parameters of access control by using NFT metadata to define specific conditions: time periods of access, geographic zones within premises, and types of actions permitted. These parameter changes allow avatars to move freely within defined boundaries while maintaining security, resolving the contradiction between mobility and security through configurable access parameters.
3Reliability
If NFTs with encrypted metadata are used to validate access requests, then controlled access to premises is achieved, but the system complexity increases due to metadata retrieval and validation processes
Solution Approach 1:
The patent uses NFTs as digital copies of access rights that can be verified without transferring physical control. The encrypted metadata in the NFT serves as a self-contained copy of authorization information that can be validated by scanning, eliminating the need for complex centralized verification systems. The NFT copy contains all necessary access information locally, simplifying the validation process while maintaining reliable access control.
4Measurement precision
If metadata containing encrypted NFT public keys is scanned to verify avatar information, then access request validation is improved, but processing time increases due to encryption and decryption operations
Solution Approach 1:
The patent performs preliminary encryption of access rights information when issuing NFTs to avatars. The encrypted metadata is prepared in advance with the NFT public key, so that during validation, only decryption and verification are needed rather than full cryptographic operations. This preliminary action reduces validation time while maintaining precise verification accuracy through pre-configured encrypted credentials.
Data Source
AI summary
A method for securing metaverse premises using Non-Fungible Tokens (NFTs), is disclosed. In some embodiments, the method includes receiving an access request corresponding to at least one of a plurality of premises, from an avatar of a user. The method further includes retrieving the metadata associated with the avatar of the user based on the NFT, upon receiving the access request. The method further includes validating the access request received from the avatar based on the metadata. The method to validate further includes scanning the metadata associated with the avatar to verify information associated with the avatar based on the NFT. The method further includes providing an access of the at least one of the plurality of premises to the avatar upon validating the access request.
