Abstract
Image Stegano is an open-source Cybersecurity & Ethical Hacking project. Analysis and Implementation of Image Steganography methods using Java. "Steganography is the art and science of communicating in a way which hides the existence of the communication. In contrast to Cryptography, where the enemy is allowed to detect, intercept and modify messages without being able to violate certain security premises guaranteed by the cover message with the embedded cryptosystem. It is built using Java. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.
1. Introduction
"Steganography is the art and science of communicating in a way which hides the existence of the communication. In contrast to Cryptography, where the enemy is allowed to detect, intercept and modify messages without being able to violate certain security premises guaranteed by the cover message with the embedded cryptosystem. The goal of Steganography is to hide messages inside other harmless messages in a way that does not allow any enemy to even detect that there is a second message present". In image steganography the information is hidden exclusively in images.
Steganography is employed in various useful applications, e.g. secret communication among agencies / people, copyright control of materials, enhancing robustness of image search engines and smart IDs (identity cards) where individuals’ details are embedded in their photographs. Other applications are video-audio synchronization, companies’ safe circulation of secret data, TV broadcasting, TCP/IP packets (for instance a unique ID can be embedded into an image to analyze the network traffic of particular users). In steganography many different carrier file formats can be used, but digital images are the most popular because of their frequency on the Internet.
2. Objective
Analysis and Implementation of Image Steganography methods using Java
This project demonstrates how Java can be applied to a real-world Cybersecurity & Ethical Hacking problem.
