Blockchain Asset Authentication Token System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-counterfeit measures are insufficient against sophisticated counterfeiting techniques, leading to market flooding with counterfeit products that dilute legitimate manufacturers' profits, compromise consumer safety, and reduce quality control.
Innovation Solution
A blockchain-based system generates a token with a digital signature using a manufacturer's creation key, locking it until the asset reaches a specific point in the supply chain, allowing authentication and ownership registration upon unlocking, thereby distinguishing authentic from counterfeit products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anti-counterfeit measures are used, then implementation is simple, but they are insufficient against sophisticated counterfeiting techniques
Solution Approach 1:
The patent introduces a blockchain-based token as an intermediary between the manufacturer and the asset. The token contains a digital signature created using the manufacturer's creation key and serves as a verifiable certificate of authenticity. This intermediary mechanism provides robust anti-counterfeiting protection without requiring complex verification systems at each point in the supply chain, as the blockchain network itself performs the verification.
Solution Approach 2:
The system performs preliminary actions by generating and locking the authentication token at the manufacturer's point, before the asset enters the supply chain. The token is created with the digital signature and locked until the asset reaches a predetermined point, ensuring that authentication data is prepared in advance and cannot be tampered with during transit or distribution.
2Reliability
If tokens are locked until asset reaches predetermined point, then counterfeit detection is improved, but processing time increases
Solution Approach 1:
The token is generated and locked in advance at the manufacturer's point, with all authentication data prepared before the asset enters the supply chain. This preliminary action ensures that when the asset reaches the predetermined point, the unlocking process is rapid and straightforward, minimizing time loss while maintaining high counterfeit detection accuracy.
Solution Approach 2:
The token's state transitions dynamically from locked to unlocked based on the asset's position in the supply chain. The system monitors the asset's movement and automatically unlocks the token when the predetermined point is reached, providing flexible and efficient authentication timing that adapts to the specific supply chain context.

AI summary
Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving an indication of an asset of a manufacturer and a code associated with the asset, generating a token linked to a blockchain of the manufacturer, wherein the token includes a digital signature created using a creation key of the manufacturer, associating the token to the code of the asset, wherein the token remains locked until an indication is received, receiving the indication indicating the asset has passed a point of a supply chain and unlocking the token in response to receiving the indication.
