Review of steganography techniques
Namita Verma · 2011
In this paper we analyze and test several steganographic techniques on still images. We show that embedding a large amount of data into the picture can modify its visible properties. We compare the LSB, DCT and Wavelet steganographic techniques; we also analyze their advantages and disadvantages in hiding secret data. In steganography it is important that the embedded data size should be minimum so that host image will not annihilate.
