Blockchain for Fake Product Detection - Project Guide for IT and Computer Engineering
1. Introduction
The Blockchain for Fake Product Detection system addresses counterfeit product issues by leveraging blockchain technology. It enables verification of product authenticity through immutable records, promoting trust among manufacturers, suppliers, and customers.
2. Objectives
- Create a decentralized platform for tracking product authenticity.
- Enable customers to verify product origins and supply chain information.
- Reduce counterfeit products in the market.
- Build trust between manufacturers and consumers.
3. Key Components
3.1 Blockchain Network
- Use a blockchain platform (Ethereum, Hyperledger, etc.) for immutable record-keeping.
- Store product-related data securely.
3.2 Smart Contracts
- Automate product registration, transfer of ownership, and verification.
- Implement anti-counterfeit mechanisms.
3.3 Product Identification
- Utilize QR codes, RFID tags, or digital signatures for product tracking.
- Ensure unique identification of every product.
3.4 Customer Interface
- Provide an app or web portal for customers to verify product authenticity.
- Display supply chain information to enhance transparency.
4. System Architecture
4.1 Workflow
1. Manufacturers register products on the blockchain.
2. Each product is tagged with a unique identifier (QR code or RFID).
3. Supply chain events are recorded as transactions.
4. Customers scan the identifier to verify authenticity.
4.2 Data Storage
- Store product metadata and supply chain events on the blockchain.
- Use decentralized storage for additional product details.
4.3 Verification Process
- Hash product data for secure storage.
- Allow customers to verify the hash against blockchain records.
5. Development Frameworks and Tools
- Blockchain SDKs: Truffle, Hyperledger Composer, or Remix IDE.
- Programming Languages: Solidity, Go, or JavaScript.
- Libraries: Web3.js, ethers.js, or Hyperledger Fabric.
- Frontend Development: React.js, Angular, or Flutter.
- APIs: Infura, Alchemy, or custom API for blockchain interaction.
6. Implementation Steps
6.1 Setup the Blockchain Environment
- Choose a blockchain platform (Ethereum, Hyperledger, etc.).
- Configure nodes for the network.
6.2 Develop Smart Contracts
- Implement contracts for product registration and verification.
- Include logic for supply chain event recording.
6.3 Integrate Product Identification
