Information Hiding in Color Image Using Steganographic technique

Abstract

Steganography is one of the important research subjects in the field of
information security. It enables secret communication by embedding
messages in the texts, images, audio, video files or other digital carriers.
Among all the image information hiding methods, LSB embedding is
widely used for its high hiding capacity and it is with great significance to
detect the images with hidden messages produced by LSB embedding
effectively, accurately and reliably. Therefore, many experts made efforts
on the LSB steganography and steganalysis research over the years. This
research presents a steganographic technique based on using LSB of one of
the pixel color components in the image and changes them according to the
message’s bits to hide. The rest of bits in the pixel color component
selected are also changed in order get the nearest color to the original one
in the scale of colors. This new method has been tested with others that
work in the spatial domain through applying some common metrics which
give us good result as a compared with the other steganographic tools.
