SteganographyDemo

Overview

This project demonstrates the use of steganography to hide messages within images. Steganography is the practice of concealing a message within another medium, such as an image, in such a way that only the intended recipient can detect the presence of the hidden message. This works by storing data in the least significant bit of each R, G, and B value of a pixel; this would mean 3 bits of storage per pixel. Because this only slightly changes the last bit of each RGB value, the difference is negligible.

Features

• Convert a text message to a binary string.
• Hide a binary message within the least significant bits of an image's pixels.
• Extract a hidden message from an image.

Requirements

• Python 3.x
• Pillow library (Python Imaging Library fork)

Installation

1. Clone the repository:

   git clone https://github.com/TheMasterOf9Winds/SteganographyDemo.git
   cd SteganographyDemo

2. Install the required dependencies:

   pip install pillow

Usage

Hiding a Message

To hide a message within an image, use the hide_message_in_image function. This function takes an image file and a message string as input and saves a new image file 'hidden_message_image.png' with the hidden message in the same directory.

NOTE: This will create or overwrite a file named 'hidden_message_image.png' in the same directory when hiding a message.

Example:

from steganography import hide_message_in_image, reveal_message_in_image

# Hide a message
hide_message_in_image('input_image.png', 'Secret Message')

# Extract the hidden message
message = reveal_message_in_image('hidden_message_image.png')
print('Extracted Message:', message)
