Blockchain Product Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face challenges in verifying the authenticity and origin of physical products due to the prevalence of counterfeit goods and a lack of real-time supply chain information, which existing technologies fail to address effectively.
Innovation Solution
A blockchain-based product verification system that generates unique tokens for each product instance, tracking its supply chain process by transferring tokens among entities and recording transactions in a blockchain ledger, allowing for real-time authentication and providing consumers with detailed information about the product's origin and manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional authentication methods are used, then product verification is simple, but consumers cannot access real-time supply chain information
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that mediates between consumers and supply chain entities. The blockchain ledger acts as a neutral intermediary that stores and verifies supply chain information, allowing consumers to access real-time data without directly connecting to complex supply chain systems. This resolves the contradiction by providing information access while maintaining system complexity management through the intermediary blockchain layer.
Solution Approach 2:
The patent replaces traditional mechanical authentication systems (physical tags, manual verification) with a digital blockchain-based system. This substitution enables consumers to access comprehensive supply chain information through digital tokens and blockchain verification, transforming the authentication process from simple physical verification to information-rich digital verification while managing complexity through standardized protocols.
2Reliability
If blockchain-based tracking is implemented, then product authenticity is verified, but system complexity increases
Solution Approach 1:
The patent creates simplified digital representations (tokens) of complex supply chain records on the blockchain. Instead of requiring consumers to interact with the full blockchain complexity, the system generates accessible token copies that contain essential authentication information. This allows reliable verification while presenting a simplified interface to end users, resolving the contradiction between authentication reliability and perceived system complexity.
Solution Approach 2:
The patent segments the blockchain authentication system into distinct layers: the underlying blockchain infrastructure for data integrity, intermediate smart contracts for business logic, and simplified token interfaces for consumer interaction. This segmentation allows each layer to handle complexity appropriately, ensuring reliable authentication while exposing only necessary complexity to users through segmented, purpose-specific interfaces.
3Loss of information
If real-time supply chain tracking is provided, then consumer information needs are met, but data security risks increase
Solution Approach 1:
The patent applies local quality by providing different levels of information access to different users based on their roles and permissions. Consumers receive appropriate supply chain information for verification purposes, while sensitive business data remains protected. The blockchain system maintains transparent tracking for authentication purposes while applying selective privacy controls, resolving the contradiction between information transparency and security by making information quality local to user needs.
Solution Approach 2:
The patent implements preliminary anti-action by incorporating security measures at the design stage rather than as afterthoughts. The blockchain system uses cryptographic hashing, digital signatures, and permissioned access controls built into the architecture from the beginning. These preliminary security actions prevent data breaches and unauthorized access before they can occur, allowing real-time tracking transparency while proactively counteracting potential security threats.
Data Source
AI summary
Methods and systems are presented for providing instant authentication of a product and enhanced user experience with the product via blockchain technologies. A product verification system uses blockchain technologies to track the supply chain process of each instance (e.g., each copy) of a product. Upon receiving a request for authenticating an item, a code provided with the item is scanned. A token corresponding to an instance of a product is determined based on the code. The product verification system traverses a blockchain to access data associated with the token. The item is authenticated based on the data. Additional content provided by the supply chain and/or the manufacturer of the instance of the product may be presented on a user device in response to authenticating the item.
