Dual Anti-Counterfeiting Code with QR and Star Map Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-counterfeiting technologies, particularly QR codes, are easily forgeable, making it difficult for consumers to verify product authenticity, and lack effective methods for ordinary consumers to distinguish between original and forged codes.
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 secondary verification, enhancing security through unique identifiers and obfuscation information.
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 code is easy to forge and difficult to distinguish between original and forged codes
Solution Approach 1:
The anti-counterfeiting code is segmented into two distinct parts: a QR code for information storage and query, and a Star Map code for verification. This segmentation allows each component to have specialized functions, with the QR code handling data storage and the Star Map code providing forgery-resistant verification, thereby improving anti-counterfeiting effectiveness while maintaining manageable system complexity
Solution Approach 2:
The Star Map code is nested within or alongside the QR code to form a composite anti-counterfeiting structure. The Star Map code contains verification information that complements the QR code, creating a layered verification system where the inner Star Map code provides the security layer while the outer QR code provides the information layer
2Reliability
If a dual verification system with Star Map code overlay is implemented, then the security and reliability of product verification is enhanced, but the complexity of the anti-counterfeiting code structure increases
Solution Approach 1:
The QR code and Star Map code are merged into a single composite anti-counterfeiting structure that can be printed together on product packaging. This merging allows the system to leverage the information-storage capability of QR codes and the verification-security of Star Map codes simultaneously, enhancing product verification security while presenting a unified code structure to consumers
Solution Approach 2:
The composite anti-counterfeiting code structure serves multiple functions: the QR code portion stores and transmits product information, while the Star Map code portion provides forgery-resistant verification. This multi-functionality allows a single code structure to accomplish both information delivery and security verification, improving verification security without requiring separate systems
3Reliability
If two anti-counterfeiting verification methods are required, then the risk of code copying is reduced, but the time and steps required for verification increase
Solution Approach 1:
The Star Map code is pre-configured with verification information during code generation, so that when a consumer scans the code, the verification data is already prepared and embedded. This preliminary action eliminates the need for complex real-time verification processes, reducing verification time while maintaining strong resistance against code copying
Solution Approach 2:
The Star Map code uses a verification mechanism that is inherently difficult to copy or replicate, as it contains encrypted or uniquely generated verification data. This copying-resistant design reduces the risk of code duplication while the integrated structure with QR code allows rapid scanning, minimizing verification time

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.
