Image Steganography

Abstract

1. Introduction

A command-line interface based program for Image Steganography. It uses Least Significant Bit(LSB) algorithm for Image Steganography.

A new image will be created in your Images directory with the secret message hidden in it.

The hidden message will be displayed on your console.

2. Objective

:closed_lock_with_key:ㅤA C++ program for Image Steganography

This project demonstrates how C++ can be applied to a real-world Cybersecurity & Ethical Hacking problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Arduino IDE / PlatformIO or a C++ compiler (g++)
• Target board (e.g. Arduino, ESP32) where applicable
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/hitanshu-dhawan/ImageSteganography.git
cd ImageSteganography

1. Install Open-CV :
2. Compile the program :

$ cd ImageSteganography
  $ chmod +x make_encode
  $ chmod +x make_decode
  $ ./make_encode
  $ ./make_decode

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.
