Steganography In Images
ABSTRACT:
In this paper, we aim to present a general introduction to steganography or data-hiding as
it is sometimes just known. We then turn to data-hiding in images. When examining these
data-hiding techniques, we bear in mind Bender's specifications, such as degradation of
the cover data must be kept to a minimum, and the hidden data must be made as immune
as possible to possible attack from manipulation of the cover data.
Steganography in images has truly come of age with the invention of fast, powerful
computers. Software is readily available off the Internet for any user to hide data inside
images. These softwares are designed to fight illegal distribution of image documents by
stamping some recognisable feature into the image.The most popular technique is Least
Significant Bit insertion, which we will look at. Also, we look at more complex methods
such as masking and filtering, and algorithms and transformations, which offer the most
robustness to attack, such as the Patchwork method which exploits the human eye's
weakness to luminance variation.
we will take a brief look at steganalysis, the science of detecting hidden messages and
destroying them. We conclude by finding that steganography offers great potential for
securing of data copyright, and detection of infringers. Soon, through
steganography,personal messages,files, all artistic creations, pictures, and songs can be
protected from piracy.
