Detail Description

1. Abstract

Fake Product Detection Using Blockchain is a system designed to identify counterfeit products and verify product authenticity throughout the supply chain. It uses blockchain technology, unique product IDs, QR codes, and smart contracts to maintain tamper-evident product records. Manufacturers register genuine products, and customers or retailers scan QR codes to verify product details and trace product history. The system improves transparency, reduces counterfeit risks, and builds trust between manufacturers, sellers, and consumers.

2. Objectives

To detect and prevent counterfeit products.
To verify product authenticity using blockchain.
To generate unique product IDs and QR codes.
To maintain transparent product tracking records.
To enable customers to verify products easily.
To improve supply chain security and consumer trust.

3. Existing System

Traditional product verification relies on labels, barcodes, packaging, and centralized databases. Counterfeiters can copy product labels and QR codes, making it difficult for customers to distinguish genuine products from fake ones.

Disadvantages:

Fake labels and QR codes can be duplicated.
Product information may be modified.
Limited supply chain transparency.
Manual verification can be time-consuming.
Customers may unknowingly purchase counterfeit products.

4. Proposed System

The proposed system uses blockchain technology and smart contracts to register genuine products and verify their authenticity. Each product receives a unique identifier and QR code linked to its blockchain record. Customers can scan the QR code to check product details, manufacturing information, and supply chain history. The system flags unregistered products or suspicious verification results.
