Recent Advances in Steganography 54histogram modifications.The resulting covered/stego images are reasonably robust against main geometrical attacks, which do not change the image histogram, with high quality measurements in terms of human vision system as well as statistically.Rest of the chapter is organized as follows.Fundamentals of the digital image and image steganography are explained in the following section.Section three details both contemporary approaches to the histogram modification-based data hiding and the HSV method, its implementation, example applications in three well known images together with comparisons to those of the other classical counterparts and its steganalysis.And, final remarks are presented in the last section.
