There is a need for a secure and efficient way to authenticate resource transfers in a virtual environment, ensuring that resources are transferred by authorized transferors and recipients, while addressing security and privacy concerns inherent in metaverse technologies.
Innovation Solution
A system using tokenization, where transferor and resource NFTs are generated and digitally signed, allowing authentication through a distributed ledger, with smart contracts verifying authorized transferors and resources, and ensuring secure transfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital signatures and distributed ledgers are used for authentication, then security and reliability are improved, but device complexity and processing overhead increase
Solution Approach 1:
The system performs preliminary actions by pre-generating transferor NFTs with embedded public keys and pre-storing authorized transferor lists in resource NFTs before actual resource transfers occur. This allows authentication data to be prepared in advance, reducing real-time processing complexity while maintaining high security through cryptographic verification.
Solution Approach 2:
The patent introduces NFTs (Non-Fungible Tokens) as intermediary objects that mediate between transferors and resources. Transferor NFTs serve as cryptographic credentials, while resource NFTs act as authorization repositories. These intermediaries simplify the authentication process by encapsulating complex cryptographic operations into standardized token structures that can be easily verified.
2Reliability
If multiple verification steps are implemented, then authentication reliability is improved, but processing time and operational complexity increase
Solution Approach 1:
The patent merges multiple authentication verification steps into a single integrated process. The system combines transferor identity verification, authorization validation, and resource ownership confirmation into one unified authentication flow where all checks are performed simultaneously through smart contract execution, rather than as separate sequential steps.
Solution Approach 2:
The authentication system operates autonomously through self-verification mechanisms. Transferors automatically present their NFT credentials, and the system self-validates authorization by checking against stored authorized transferor lists. This eliminates manual verification steps and reduces operational complexity while maintaining rigorous authentication standards.
3Reliability
If cryptographic key pairs are used for each transferor, then security is improved, but storage requirements and system complexity increase
Solution Approach 1:
Instead of storing complete cryptographic key pairs for each transferor, the system stores only public keys within transferor NFTs and maintains authorized transferor lists in resource NFTs. This copying approach stores minimal essential data (public identifiers) rather than full cryptographic credentials, significantly reducing storage requirements while preserving authentication security through public key verification.
Data Source
AI summary
A system is provided for authentication of resource transfers using tokenization as indicator of authorized resource distribution. In particular, the system may be configured to generate a secure transferor token on a distributed register, where each transferor token may be associated with a resource transferor within a virtual environment. The transferor token may be digitally signed using a transferor private key such that the transferor may be authenticated by entities using the corresponding public key. The system may further generate a secure token associated with the resource to be transferred, where the token associated with the resource may specify a list of authorized transferors as one of its parameters. Accordingly, the system may ensure that resources are transferred by authorized transferors.
