Detection and Implementation of Robust Image Steganography by Using LSB Injection Technique

Abstract

The art or science of concealing the existence of data within an ordinary and inconspicuous medium or host is called Steganography and the art of detecting the hidden message embedded in digital media using Steganography is called Steganalysis. There are many different carriers for steganography but the most popular is digital images. The Least Significant Bit of a file is the last bit (technically speaking, it is the first) in an 8-bit byte, which modifies the value of the byte by only 1 if changed.

Original and output data are compared to each other and the robustness of the application against steganalysis attacks is measured using SHADE tools. This paper focuses on the techniques of Least Significant Bit (LSB), Embedding using digital images as a medium and an overview of image Steganography, its uses and techniques.

In this paper a new method is presented, implemented and analyzed.
