NFT-Embedded Tag Authentication via Cryptographic Key Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Counterfeit goods pose a challenge as they deceive consumers into purchasing inferior products by mimicking authentic goods, harming both consumers and the original manufacturer's reputation, and existing authentication methods lack effectiveness in securely verifying product authenticity.
Innovation Solution
The integration of Non-Fungible Tokens (NFTs) with cryptography to securely link physical goods, where an NFT is minted with a unique identifier and embedded in an electronic tag device, enabling authentication through public and private key encryption, thereby ensuring the authenticity and ownership of the product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used to verify product authenticity, then the authentication process can be performed, but the security and effectiveness of verification is insufficient against counterfeit goods
Solution Approach 1:
The patent introduces an NFT as an intermediary digital token that mediates between the physical product and the authentication system. The NFT contains cryptographic keys and product information, serving as a secure bridge that verifies authenticity without exposing sensitive data. This intermediary mechanism effectively blocks counterfeit deception while maintaining reliable authentication.
2Reliability
If cryptographic keys are stored in the physical good for authentication, then security is improved, but the device complexity increases due to embedded electronic tag devices
Solution Approach 1:
The patent embeds the electronic tag device containing cryptographic keys within the physical product, creating a nested structure where the authentication mechanism is integrated inside the product itself. This nesting approach secures the cryptographic keys within the product while managing the complexity through standardized embedded device design.
3Reliability
If public and private key encryption is implemented for product authentication, then authentication security is enhanced, but the ease of operation decreases due to complex encryption processes
Solution Approach 1:
The patent implements self-service authentication where the electronic tag device automatically performs cryptographic operations and verification without requiring user intervention. The system autonomously handles key management, encryption, and authentication processes, making the secure authentication transparent and easy to operate for end users.

AI summary
In an example, a non-transitory machine-readable storage medium includes stored instructions. The store instructions, when executed by one or more processors, cause the one or more processors to: receive a unique identifier of a tagged physical good; receive a public key stored in a Non-Fungible Token (NFT) corresponding to the unique identifier; encrypt a first passphrase using the public key to obtain an encrypted passphrase; compare a second passphrase to the first passphrase; and generate an output indication in response to comparing the second passphrase to the first passphrase. The second passphrase is generated by decrypting the encrypted passphrase using a private key stored on an electronic tag device embedded in the tagged physical good.
