Introduction

An Online Voting System is a web-based platform that allows users to cast votes remotely, replacing traditional paper-based or EVM methods. It’s ideal for college elections, society polls, or small organizational voting.

Important Security & Customization Tips

| Area | Recommendation | |-----------------------|------------------------------------------------------------------------------------| | Default passwords | Change immediately. Store hashed passwords in DB. | | SQL injection | Use prepared statements ($stmt = $conn->prepare(...)). | | Multiple votes | Check voter’s has_voted flag before updating votes table. | | Session security | Regenerate session ID after login (session_regenerate_id(true)). | | Portable deployment | Never expose the portable server to the public internet without firewall rules. |

4. System Architecture

The system follows a Three-Tier Architecture:

1. Presentation Layer (Client): HTML5, CSS3, Bootstrap for responsive UI. Handles user input and displays results.
2. Business Logic Layer (Server): PHP scripts handle authentication, vote logic, session management, and database queries.
3. Data Layer (Database): MySQL stores user credentials, candidate details, and vote records.
