Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used, then implementation is simple, but security against counterfeiting is insufficient
Solution Approach 1:
The patent combines NFC technology, blockchain, and cryptographic algorithms into an integrated authentication system. The NFC tag stores product information, blockchain provides decentralized verification, and cryptographic algorithms ensure data integrity, creating a multi-layered security system that addresses counterfeiting while maintaining manageable complexity through unified architecture.
Solution Approach 2:
The patent introduces a blockchain-based intermediary layer between product identification and verification. This intermediary provides a trusted, decentralized ledger that records authentication transactions, enabling secure verification without requiring direct trust between parties and significantly enhancing security against counterfeiting.
2Stability of the object's composition
If blockchain technology is implemented for product verification, then data immutability is achieved, but transaction costs increase
Solution Approach 1:
The patent extracts only the essential authentication data (product ID, verification status, timestamp) to the blockchain, while storing detailed product information locally in NFC tags and databases. This selective extraction minimizes blockchain transaction size and cost while maintaining data immutability for critical verification information.
Solution Approach 2:
The patent uses lightweight cryptographic hashes and compressed data representations on the blockchain, creating efficient, low-cost verification records. The system employs cost-effective cryptographic algorithms and optimized data structures that provide immutability at minimal transaction cost.
3Measurement precision
If NFC tags are encoded with cryptographic data, then verification accuracy is improved, but encoding complexity increases
Solution Approach 1:
The patent performs preliminary encoding of NFC tags during product manufacturing, embedding cryptographic identifiers and product information before distribution. This preliminary action ensures verification accuracy is established from the outset, and the encoding complexity is managed during production rather than at verification points.
Solution Approach 2:
The patent employs cryptographic parameter transformations, converting product information into secure cryptographic formats suitable for NFC storage. By changing data parameters through encryption and hashing, the system achieves high verification accuracy while managing encoding complexity through standardized cryptographic protocols.
Data Source
AI summary
A system, method and process for product authentication and verification using Near Field Communication (NFC) technology, blockchain technology (Hyperledger), and cryptography. A unique product identifier is generated for a unique individual product, incorporated into a data structure for that product, and the data structure is recorded to a blockchain initiating an immutable record for the unique product identifier. An NFC tag is encoded with a tap-unique URL that comprises the unique product identifier and a cryptographic output and the tag is affixed to its corresponding unique individual product. Each time the tag is tapped by an NFC proximity coupling device, a web client operating on the proximity coupling device reads and opens the URL whereupon the tag is verified using a cryptographic verification process and generating a verification result. The verification result is transmitted to and recorded on the blockchain ledger for the unique product identifier, thereby creating an immutable record of each tap interaction result of the tag affixed to the product. In embodiments, a verification certificate comprising the verification result is transmitted to the web client operating on the proximity coupling device for viewing by a user.
