Single-Use Code Verification on Blockchain for Supply Chain Authenticity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized anti-counterfeit solutions in supply chain tracking are vulnerable to single points of failure and lack transparency, making it difficult for consumers and producers to trust the authenticity of products, particularly in decentralized supply chains.
Innovation Solution
A decentralized anti-counterfeit system using single-use codes, where secret codes are packaged with products in tamper-evident packaging, generating one-way encrypted codes based on product identifiers, and recording these codes on a decentralized database like blockchain, enabling verification through smart contracts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized anti-counterfeit solutions are used, then supply chain tracking can be implemented, but the system becomes vulnerable to single points of failure and lacks transparency
Solution Approach 1:
The system segments the centralized anti-counterfeit function into distributed components across multiple nodes in the supply chain. Each participant (producer, distributor, retailer, consumer) has a local copy of the ledger and can independently verify authenticity, eliminating the single point of failure while maintaining transparency through shared data access.
Solution Approach 2:
The patent implements multiple copies of the anti-counterfeit ledger distributed across different participants in the supply chain. Each participant maintains a local copy that can be independently accessed and verified, ensuring system continuity even if one node fails and providing transparency through shared data access.
2Reliability
If single-use codes are used for anti-counterfeiting, then product authenticity can be verified, but the codes must be packaged in tamper-evident packaging which adds complexity
Solution Approach 1:
The patent merges the physical tamper-evident packaging with the digital single-use code system. The packaging physically protects the code while providing visual evidence of tampering, and this physical protection is complemented by digital verification mechanisms that confirm authenticity and prevent code reuse, creating a unified security system.
Solution Approach 2:
The tamper-evident packaging incorporates visual indicators such as color-changing elements or holographic features that change appearance when tampered with. These visual cues provide immediate physical evidence of authentication status while working in conjunction with the digital verification system.
3Loss of information
If one-way encrypted codes are generated and recorded on decentralized database, then transparent tracking is achieved, but the verification process becomes more complex
Solution Approach 1:
The system enables self-service verification where consumers can independently authenticate products using simple steps (scanning QR code, entering code) without needing to understand or manage the complex underlying cryptographic verification process. The decentralized database and smart contracts automatically handle the complex one-way encryption verification, providing transparency while simplifying user interaction.

AI summary
Systems and methods for providing a decentralized anti-counterfeit solution for supply chain tracking are disclosed. Exemplary implementations may: electronically store a product identifier that identifies a physical product; generate a secret code that is packaged with the physical product in a tamper-evident manner; generate a one-way encrypted code based on the secret code and the product identifier; create an asset that includes code executable by a decentralized database; record the asset on a decentralized database; record the one-way encrypted code in the asset; receive a request for verification regarding a given physical product; generate a given one-way encrypted code based on the request; determine whether the given one-way encrypted code is a match of the one-way encrypted code as recorded in the asset; responsive to a match, return a notification to the given user and remove the one-way encrypted code from the asset.
