Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack a secure and efficient method for authenticating and managing products to combat counterfeiting and enhance security, transparency, and traceability in supply chains.
Innovation Solution
A system utilizing Near Field Communication (NFC) technology integrated with a Java and SQL built API and a transaction fee-free private blockchain (Hyperledger) generates a unique product identifier, encodes it onto an NFC tag, and records interactions on a blockchain for tamper-proof verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used, then system simplicity is maintained, but security and counterfeiting prevention are insufficient
Solution Approach 1:
The authentication system is segmented into multiple independent components: NFC tags embedded in products, blockchain ledger for immutable recording, cryptographic modules for secure verification, and database systems for data management. Each component performs a specific function, collectively providing robust authentication while maintaining manageable system complexity through modular architecture
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between product authentication and verification. The blockchain ledger acts as a trusted mediator that records and verifies product authenticity data without requiring direct trust between all system participants, thereby enhancing security while providing a clear intermediary mechanism for managing system complexity
2Loss of information
If comprehensive product tracking is implemented, then supply chain transparency is improved, but data management complexity increases
Solution Approach 1:
The patent implements a universal data structure framework that serves multiple functions: it tracks product authentication status, records supply chain transactions, stores cryptographic verification data, and maintains blockchain ledger entries. This multi-functional data structure reduces the need for separate management systems for each function, thereby improving supply chain transparency while managing data complexity through consolidation
Solution Approach 2:
The data management system employs a nested structure where cryptographic data structures are embedded within blockchain transactions, which are in turn recorded in the distributed ledger. This nested organization allows comprehensive product tracking information to be systematically structured, making complex data management more manageable through hierarchical arrangement
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, 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 comprising the unique product identifier and a cryptographic output and affixed to the product. Each time the tag is tapped by a proximity coupling device, a web client operating on the proximity coupling device opens the URL whereupon the tag is verified using a cryptographic verification process and generating a verification result. The verification result is recorded on the blockchain ledger for the unique product identifier, thereby creating an immutable record of each tap interaction result.
