NFC Tag Authentication With Blockchain Ownership Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems lack functionality for securely authenticating products, transferring ownership, managing insurance, preventing theft, and tracking products in primary and secondary markets, while failing to allow producers to gather data and communicate with consumers regarding secured, traceable digital and physical assets.
Innovation Solution
A system utilizing NFC tags and blockchain technology to authenticate products, record transactions, and manage ownership transfers, insurance processes, and theft prevention, while enabling data tracking and consumer engagement through a secure product authentication ecosystem.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication systems are used, then product verification is possible, but security against counterfeiting is insufficient
Solution Approach 1:
The patent introduces NFC tags as intermediary devices attached to physical products, which store unique identifiers and communicate authentication data wirelessly. This intermediary layer enables secure verification without requiring direct connection between verifier and product, enhancing security while maintaining simplicity
Solution Approach 2:
The patent replaces conventional mechanical or manual authentication systems with wireless NFC-based electronic verification. The NFC technology enables contactless communication between reader and tag, substituting physical inspection or manual verification processes with automated electromagnetic field-based authentication
2Reliability
If blockchain technology is implemented for transaction recording, then data integrity and traceability are improved, but system complexity increases
Solution Approach 1:
The patent implements smart contracts that automatically execute authentication logic and transaction recording when NFC tags are verified. The blockchain infrastructure is pre-configured with smart contracts that contain predefined authentication rules, eliminating the need for complex real-time decision-making algorithms and reducing operational complexity
Solution Approach 2:
The blockchain system operates as a decentralized self-service network where nodes independently validate and record transactions according to consensus protocols. This eliminates the need for centralized authentication authorities and complex manual verification processes, achieving high data integrity through distributed consensus rather than centralized control
3Adaptability or versatility
If NFC tags are integrated with blockchain, then product tracking and ownership management are enhanced, but implementation complexity increases
Solution Approach 1:
The patent creates a universal NFC tag system that serves multiple functions: product authentication, ownership tracking, transfer of title, and insurance management. The same NFC infrastructure and blockchain platform support diverse use cases across different industries, reducing implementation complexity through standardized multi-functional design rather than separate specialized systems

Implementation Method 1
receiving, by an application executing on a first computing device, from an NFC reader, a unique identifier of an NFC tag physically connected to a product
Data Source
AI summary
A method includes receiving, by an application executing on a first computing device, from an NFC reader, a unique identifier of an NFC tag. A second computing device stores an identification of the product and the unique identifier of the NFC tag in a blockchain. The second computing device receives, from a third computing device, a request for a determination of authenticity of the NFC tag. The second computing device requests, from the blockchain, an indication of whether the unique identifier of the NFC tag is stored in association with the identification of the product and an indication of ownership. The second computing device receives confirmation that the unique identifier of the NFC tag is stored in association with the identification of the product and the indication of ownership. The second computing device provides, to the third computing device, the confirmation.
