Abstract

Digital image steganography techniques deal with three subjects lossy/lossless
compressed images, uncompressed images. Steganography techniques embed secret data
pixel directly into uncompressed and lossless compressed cover images. The most popular
data hiding method is, changing pixels’ left most digits or last two, known as Least
Significant Bit (LSB). Lossless image formats like .bmp, .png, and 8-bit gray-scale .gif are
usable for LSB methods. LSB embedding method is not usable for palette images because
of changing just last bit of a pixel causes a big difference on image. After embedding all of
secret message to palette image, Human Visual System (HVS) can detect manipulations
on image. In this study, we compare some of the most popular LSB techniques; Chan’s
algorithm [3], 2/3 efficient embedding [4], matrix embedding for large payloads [5], image
blocks method [6] and pixel-value differencing method [7]-[8].
