Technical Architecture and Implementation
The system follows a three-tier architecture design pattern combining frontend presentation, backend business logic, and blockchain persistence layers. The Django framework handles HTTP requests and orchestrates communication between the AI engine and blockchain service modules.
Document processing begins when users upload files through the web interface. The AI engine module performs optical character recognition using Tesseract for text extraction, followed by forgery analysis algorithms that examine document metadata, pixel patterns, and structural integrity. Simultaneously, a SHA-256 hash is generated and sent to the Ethereum smart contract deployed on the Ganache local blockchain.
The Solidity smart contract implements document registry functionality with mapping structures that store document hashes, registration timestamps, and uploader addresses. Web3.py library facilitates transaction signing using private keys and handles gas estimation for contract interactions. All blockchain transactions are recorded immutably, creating an auditable trail of document registrations.
