Dual Anti-Counterfeiting Code With QR and Star Map Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-counterfeiting technologies, particularly two-dimensional QR codes, are easily forgeable, making it difficult for consumers to verify the authenticity of products, and lack effective tools for ordinary consumers.
Innovation Solution
A dual anti-counterfeiting code system is implemented by overlaying a Star Map code on a QR code, involving two distinct verification methods: scanning the QR code for an initial check and using a star code recognition system for a secondary verification, enhancing security through unique identifiers and encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a QR code is used for anti-counterfeiting verification, then product information can be stored and queried, but the QR code is easily forged and copied
Solution Approach 1:
The patent divides the anti-counterfeiting code into two independent parts: a QR code containing basic product information and a Star Map code containing encrypted verification data. Each code can be independently generated and verified, but both are needed for complete authentication, making the system more secure while maintaining ease of use
Solution Approach 2:
The Star Map code is overlaid on top of the QR code, creating a nested structure where the Star Map code serves as an additional verification layer within the QR code framework. This nested design allows the system to leverage the simplicity of QR codes while adding the security of encrypted Star Map codes
2Ease of operation
If a single verification method is used, then the verification process is simple, but the security against code copying is insufficient
Solution Approach 1:
The system performs preliminary verification by first scanning the QR code to obtain basic product information and then automatically initiating a second verification step using the Star Map code. This preliminary action ensures that even if a counterfeiter copies the QR code, the encrypted Star Map code prevents successful authentication
Solution Approach 2:
The verification system provides feedback through a two-step process: the first scan retrieves product information, and the second scan verifies authenticity. The system feeds back the verification result to the user, clearly indicating whether the product is genuine or counterfeit, thereby maintaining simplicity while enhancing security

AI summary
Provided is a method for querying and verifying a platform product based on a dual anti-counterfeiting code. The method includes: performing anti-counterfeiting encryption on a serial number or an ID of a platform product by using an encryption algorithm, and generating a unique identifier and an anti-counterfeiting URL; adding designated anti-counterfeiting information to the unique identifier by using a dot matrix generation algorithm of a micro dot code, to obtain a Star Map code; converting the anti-counterfeiting URL into a QR code and overlaying the Star Map code on the QR code to form a dual anti-counterfeiting code; scanning the dual anti-counterfeiting code to recognize a unique identifier in the QR code, and calling a star code recognition system; photographing the dual anti-counterfeiting code by using the star code recognition system, to recognize the unique identifier in the Star Map code.
