🚨 Cyber Safety & Scam Detector

A simple web-based application that helps users detect scam or suspicious messages from SMS, WhatsApp, or emails using rule-based keyword analysis.

🌟 Inspiration

Online scams are increasing rapidly, especially through SMS, WhatsApp, and email messages. Many users—especially students and elderly people—find it difficult to identify whether a message is genuine or fraudulent.
This project was inspired by the need to create a simple, easy-to-use cyber safety tool that can quickly alert users about potential scam messages.

🛠 What It Does

  • Detects scam or suspicious messages
  • Highlights the risk level based on detected keywords
  • Displays the reason for classifying a message as scam
  • Stores previous message checks (history)
  • Provides a clean and simple web interface

⚙️ How It Works

  1. User enters a message (SMS / WhatsApp / Email)
  2. The system scans the message for scam-related keywords
  3. A score is calculated based on keyword matches
  4. The message is classified as:
    • ✅ Safe
    • ⚠️ Scam / Suspicious
  5. The result and reason are shown to the user
