English Abstract
Steganography is the art and science of invisible communication, this is accomplished through hiding information in other objects in such a way that no one apart from the intended recipient knows of the information existence, thus hiding the existence of the communicated information.
In this thesis, a new method is proposed to hide a colored image of any type inside 4 channel PNG image.
The method suggests that the selected secret image is converted to an indexed image with custom color palette to reduce its size, the custom color palette is constructed using Lempel-Ziv-Welch (LZW) compression which is applied to the secret image to reduce its size so that the amount of data needed to be embedded with the secret image is reduced.
The proposed method used the least 2 significant bits and achieved better results than the true color method, this is due to the fact that the secret image size was lower after conversion than the converted image in the true color method.
