NFT Authenticity via NFC Template and Blockchain Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The authenticity of non-fungible tokens (NFTs) in digital transactions is challenging due to the lack of verification mechanisms, especially when transactions are fraudulent, undermining the value of NFTs as verifiable tokens of ownership.
Innovation Solution
The use of short-range wireless communication technologies like NFC, along with blockchain-based systems, enables the creation and distribution of cryptographic assets, including NFTs, by passing templates between creator and collector devices for validation and minting on a blockchain, ensuring authenticity and preventing duplicates through shared secret encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional digital transaction methods are used for NFT transfers, then transaction speed is improved, but authenticity verification reliability deteriorates due to lack of verification mechanisms
Solution Approach 1:
The system segments the NFT transaction process into distinct phases: a fast transfer phase using conventional digital methods, and a separate verification phase using blockchain validation. This allows the transaction to proceed quickly while authenticity is verified independently through blockchain consensus mechanisms, resolving the contradiction between speed and verification reliability.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary verification layer. Instead of relying on direct trust between parties or complex verification protocols that would slow down transactions, the blockchain serves as a neutral mediator that validates authenticity independently. The smart contract on the blockchain verifies the NFT's legitimacy without interfering with the speed of the actual transfer, thus maintaining both speed and reliability.
2Reliability
If blockchain-based verification mechanisms are implemented for NFT authenticity, then authenticity verification reliability is improved, but device complexity and resource requirements worsen
Solution Approach 1:
The patent extracts the complex verification logic from the end-user devices and relocates it to the blockchain network. Users only need to interact with simple smart contract functions to verify authenticity, while the heavy lifting of maintaining verification reliability is handled by the distributed blockchain network. This reduces device complexity while preserving verification reliability.
Solution Approach 2:
The blockchain system serves multiple functions simultaneously: it acts as a verification mechanism for NFT authenticity, a decentralized database for storing transaction records, and a trustless intermediary for facilitating transfers. By consolidating these functions into a single universal platform, the system avoids the need for multiple separate verification systems, thereby reducing overall complexity while maintaining high reliability.
3Reliability
If shared secret encryption is used to prevent duplicate NFT generation, then security against fraudulent transactions is improved, but ease of operation deteriorates due to additional encryption steps
Solution Approach 1:
The system implements self-service encryption where the shared secret mechanism automatically prevents duplicate NFT generation without requiring manual intervention. The encryption and verification processes are embedded in the smart contract logic, which automatically executes when an NFT is created or transferred. This eliminates the need for users to manually manage encryption keys or understand cryptographic protocols, thereby maintaining security while preserving ease of operation.
Solution Approach 2:
The shared secret encryption scheme is pre-configured and established before NFT creation begins. The cryptographic parameters and verification rules are set in advance through the smart contract deployment, so that during actual NFT operations, users simply need to follow straightforward steps without dealing with complex encryption mechanics. This preliminary setup reduces operational complexity while ensuring security.

AI summary
This disclosure is directed to methods and systems for cryptographic asset generation using short range wireless communication. The methods and systems enable creation and distribution of cryptographic assets with proof of in-person contact over various wireless technologies, including but not limited to, NFC, low-energy Bluetooth, and others. This is achieved by passing a cryptographic asset template from a creator device to a collector device via NFC. The cryptographic asset template is passed to a server for confirmation and subsequently starts the process of minting a smart contract on a blockchain. The processes disclosed herein include cryptographic asset template creation, template distribution, template-to-cryptographic asset creation, and smart contract execution.
