Data hiding method using image interpolation and pixel symmetry

This article is about a new keyed steganography method for data hiding inside a digital image. Thanks to proposed method the most significant property of steganography, a large amount of secret data can be embedded while keeping a very high visual quality, is achieved. The proposed method uses image interpolation and pixel symmetry. We show our experimental results in Matlab. Similar speed and needed number of iterations when compared with previous studies can be attained.
