Anti-Theft Password-Based Ignition System

Overview

The Anti-Theft Password-Based Ignition System is a security project that prevents unauthorized vehicle ignition using Face Recognition and Password Authentication. This system integrates a Raspberry Pi and a Laptop to provide a secure and automated authentication mechanism before allowing ignition.

Features

• Face Recognition for authorized users.
• Password Authentication as a backup method.
• Emergency Shutdown option for quick system disable.
• Relay Control to start or stop vehicle ignition.
• User-friendly Interface using Python and Flask.

Installation

Raspberry Pi Setup

1. Update Raspberry Pi OS:

   sudo apt update && sudo apt upgrade

2. Install Python 3 and pip:

   sudo apt install python3 python3-pip

3. Install required Python libraries:

   pip3 install RPi.GPIO requests

Laptop Setup

1. Install Python 3 (Ensure it's added to the PATH during installation).
2. Install pip:

   python -m ensurepip --upgrade

3. Install OpenCV and Flask dependencies:

   pip install opencv-python flask

Project Setup

On Raspberry Pi

1. Create a directory for the project:

   mkdir AntiTheftIgnitionSystem && cd AntiTheftIgnitionSystem

2. Place pi_main.py inside this directory.

On Laptop

1. Create a directory for the project:

   mkdir AntiTheftIgnitionSystem && cd AntiTheftIgnitionSystem

2. Place app.py and authorized_face.jpg in this directory.
3. Update laptop.py to load authorized_face.jpg for face recognition.

Running the Project

Step 1: Start the Flask Server on the Laptop

1. Open a terminal or command prompt in the project directory.
2. Run the following command:

   python app.py

3. Note the IP address and port (default: http://0.0.0.0:5000).
4. Ensure that the Laptop and Raspberry Pi are on the same network.

Step 2: Run the Raspberry Pi Script

1. Open a terminal in the Raspberry Pi project directory.
2. Run the script:

   python3 pi_main.py

3. The system will initialize and wait for input from the switches.

System Controls

• Press Switch 2 on the Raspberry Pi to trigger Face Recognition:
  • If the face matches authorized_face.jpg, the relay activates ignition.
  • If the face does not match, the system prompts for a password.
• Press Switch 3 to reset the system state.
• Press Switch 4 for emergency shutdown (with confirmation).

---

Important Notes

• Ensure that SERVER_URL in pi_main.py is updated with the laptop's IP address and port.
• The authorized_face.jpg should be clear and properly visible for recognition.
• If there are issues with dependencies, verify that Python and pip are correctly installed on both devices.
• Keep the Raspberry Pi powered with a reliable power source to avoid interruptions.
