Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack a secure and efficient method for authenticating products and ensuring transparency and traceability in supply chains, particularly in the face of counterfeiting and tampering.
Innovation Solution
A system utilizing Near Field Communication (NFC) tags integrated with a Java and SQL built API and a transaction fee-free private blockchain (Hyperledger) to encode unique product identifiers, creating an immutable tap transaction record for product authentication and verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used, then product verification can be performed, but security against counterfeiting and tampering is insufficient
Solution Approach 1:
The patent combines NFC technology, blockchain, and cryptographic hashing into a unified authentication system. The NFC tag stores product identification data, which is then hashed and recorded on a blockchain ledger, creating a merged system that leverages the contactless communication of NFC, the immutability of blockchain, and the security of cryptographic functions to resist counterfeiting and tampering.
Solution Approach 2:
The patent introduces a blockchain ledger as an intermediary between the product (via NFC tag) and the verification system. This intermediary provides a decentralized, immutable record of product authenticity, eliminating the need for trusted central authorities and making the system resistant to tampering and counterfeiting.
2Loss of information
If centralized authentication systems are used, then product verification is possible, but transparency and traceability in supply chains are limited
Solution Approach 1:
The patent enables the authentication system to be self-verifying through the blockchain ledger. Once product data is recorded on the blockchain via NFC interaction, the system automatically maintains transparency and traceability without requiring centralized management or manual verification, as the blockchain's distributed nature inherently provides auditability and transparency.
3Reliability
If complex authentication protocols are implemented, then security is enhanced, but ease of operation deteriorates
Solution Approach 1:
The patent replaces complex manual authentication processes with automated NFC-based verification. Instead of requiring users to manually verify product authenticity through multiple steps, the system uses NFC's contactless communication to automatically read product data, hash it cryptographically, record it on the blockchain, and provide verification results, thereby maintaining high security while simplifying user interaction to a single tap.
Data Source
AI summary
A system, method and process for encoding a near field communication (NFC) tag for use in product authentication and verification and to create an immutable tap transaction record. A unique product identifier is generated for a unique individual product and recorded to a blockchain initiating an immutable record for the unique product identifier. An NFC tag is encoded with a unique URL comprising the unique product identifier affixed to its corresponding unique individual product. Upon tapping by an NFC proximity coupling device, the authenticity of the tag is verified using a cryptographic verification process, and the corresponding blockchain transaction identifier is determined. The verification result and tap interaction data 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.
