Image Steganography Project

Requirements

• Python 3.x
• Pillow library (for image processing)

To install the required dependencies, run:

pip install pillow

How to Use

1. Prepare your files:

   • Choose an image in which you want to hide the data.
   • Decide on the password and the data you wish to hide.

2. Run the script:

   • Open a terminal or command prompt and navigate to the project directory.
   • Run the script by executing:

   python steganography.py

3. Input the required information:

   • Image Path: Enter the path to the image where you want to hide the data.
   • Password: Enter a password that will be used to secure the hidden message.
   • Data to Hide: Enter the text or data you want to embed within the image.
   • Output Image: Specify the output file name (e.g., stego.jpg). If left empty, it will default to stego.png.

4. Output:

   • The script will process the image and save the modified image (with the hidden data) in the specified output file.
   • You can then share the modified image securely.

Example

Enter the image path: image.jpg
Enter the password: mysecretpassword
Enter the data to hide: Hello, this is a secret message!
Enter the output image name (optional, e.g., stego.png): stego.jpg

The resulting image will have the message hidden in its pixel values and can be retrieved by authorized users who know the password.

How It Works

1. Text to Binary: The password and data are converted to binary.
2. Embed Data in Image: The binary message is embedded into the image by modifying the least significant bit (LSB) of the pixel's RGB color channels.
3. Save Modified Image: The modified image is saved as the output file.
