Solution Overview

Problem

Existing anti-counterfeiting technologies for product sales terminals are inadequate in preventing repeated use or illegal copying of anti-counterfeiting codes, leading to ineffective authentication and potential economic and safety risks.

Innovation Solution

A variable anti-counterfeiting method and system that involves a detection terminal connecting to a cloud platform, where the platform identifies and binds the terminal, changes passwords after verification, and grants access permissions based on authentication, including irreversible binding and alert messages for counterfeit detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional anti-counterfeiting codes (QR codes, RFID) are used for product verification, then consumers can verify product authenticity through scanning, but the anti-counterfeiting effectiveness is limited when products are resold multiple times or when codes are illegally copied

Engineering Contradiction:
Improveanti-counterfeiting effectivenessVSAvoidreusability of anti-counterfeiting code
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic password generation where the verification code changes based on the number of times it has been used. Each successful verification increments a usage counter, and the password is regenerated accordingly. This dynamic transformation ensures that even if a code is copied, it cannot be reused effectively since the password has already changed, thus resolving the contradiction between reliability and adaptability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the password parameter after each verification attempt. The cloud platform generates a new password based on the usage count stored in the database, transforming the static anti-counterfeiting code into a dynamic one. This parameter change ensures that the same physical code cannot be used repeatedly for verification, preventing illegal copying and resale issues

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If anti-counterfeiting codes are made reusable for product resale, then legitimate reselling is enabled, but the codes can be illegally copied and used for counterfeit products

Engineering Contradiction:
Improveresale capabilityVSAvoidcounterfeit risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system incorporates feedback mechanisms where the cloud platform tracks each verification attempt and updates the usage count in the database. This feedback loop ensures that legitimate resellers can verify products multiple times by obtaining updated passwords, while counterfeiters cannot successfully replicate the verification process since the system records and validates each usage, thus enabling legitimate resale while preventing counterfeiting

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary binding between the detection terminal and the product code before verification. This preliminary action creates a unique association that must be maintained for successful verification. Legitimate resellers who possess the original product can maintain this binding, while counterfeiters cannot establish the correct preliminary association, thus enabling legitimate resale while blocking counterfeit attempts

Inventive Principle:
Principle #10Preliminary action

3Reliability

If a centralized cloud platform verification system is implemented, then anti-counterfeiting control and password management are improved, but the system complexity and connection requirements increase

Engineering Contradiction:
Improveverification controlVSAvoidsystem architecture
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a cloud platform as an intermediary between the detection terminal and the product verification process. This intermediary handles the complex tasks of password generation, usage tracking, and verification validation, while the detection terminal itself remains relatively simple. The cloud platform mediates all verification requests, centralizing the complexity while keeping endpoint devices simple, thus improving verification control without excessively complicating the overall system

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A variable anti-counterfeiting method, system, device and medium for a product sales terminal include: identifying, by a detection terminal, a detected terminal and enabling the tested terminal to access a cloud platform, and identifying, by the cloud platform, a manner in which a current detection terminal accesses the cloud platform; discriminating, by the cloud platform, the password according to a preset comparison rule; when the cloud platform discriminates the password to be correct, changing the password according to a preset change rule, granting the current detection terminal ordinary view access to product information and exclusive view access to a changed password, and simultaneously incorporating the detected terminal into a warehousing system associated with the current detection terminal; when the cloud platform discriminates the password to be incorrect, sending a counterfeit alert message to the current detection terminal.
