Word-Based LSB Image Steganography
Main Article Content
Abstract
Steganography is the art and science of hiding important information by embedding message within other file. A new Least Significant Bit (LSB) steganography technique is presented in this work by treating the secret message based on its words content instead of its characters content. By using a specific small words dictionary by the sender and the receiver of the secret message, and representing each word in the secret message with an index in the words dictionary. Then embed these words indices, of the secret message, in the LSB of the pixels in the stego-image. The experimental results shown that the Word Based LSB technique will add more security to the secret message, reduces the distortion that will occur in the stego-image, increase the capability to hide very long secret message in a small stego-image, and minimize the time that is needed to hide and extract the secret message.
