A product V-code anti-counterfeiting system and method based on multi-party smart contract collaboration

The product V-code anti-counterfeiting system, which utilizes multi-party smart contract collaboration, achieves dynamic separation and binding of pre-sale product verification. This solves the security risks of centralized anti-counterfeiting and the dependence on physical identifiers in blockchain anti-counterfeiting, thereby improving the security and convenience of the anti-counterfeiting system.

AI Technical Summary

Technical Problem

Existing anti-counterfeiting technologies cannot effectively solve the problem of verifying goods before the purchase. Centralized architectures pose security risks, while blockchain anti-counterfeiting solutions rely on physical identifiers that are easily copied, leading to fraud such as "fake wine in a genuine bottle" and limitations of one-time verification.

Method used

The product V-code anti-counterfeiting system, based on multi-party smart contract collaboration, dynamically generates verification codes that are separate from the physical packaging to achieve pre-sale verification and records product lifecycle data on the blockchain to ensure the uniqueness and timeliness of the verification.

Benefits of technology

It significantly reduces reliance on physical anti-counterfeiting labels, improves verification convenience, enhances anti-counterfeiting security, prevents "fake wine in a genuine bottle" attacks, reduces verification costs, and supports circulation in the secondary market.

Abstract

This invention belongs to the field of blockchain application and e-commerce data security technology, specifically involving a product V-code anti-counterfeiting system and method based on multi-party smart contract collaboration. The system includes a top-level user interaction layer, a middle-level service application layer, and a bottom-level blockchain ledger layer. Through a V-code generation technology combining inventory anchoring and dynamic encryption algorithms, it achieves pre-verification of the authenticity of goods circulating in e-commerce. This solution fundamentally solves the trust linking problem between the physical and digital worlds by moving the verification process from "post-purchase" to "pre-sale" and achieving dynamic separation and binding of the verification code and physical packaging. Potential consumers can request and verify a dynamically generated V-code associated with a specific transaction intent before payment, effectively avoiding the risk of counterfeiters using recycled genuine packaging for fraudulent purposes, and building a truly safe, convenient, and low-cost pre-sale "firewall" for consumers.
