Abstract— Data hiding is to conceal the existence of secret data and it is considered for more protection of multimedia data. A reversible data hiding method can extract the cover image without any distortion from the stego-image after the hidden data have been extracted. This study tackles a chaotic based reversible data hiding. In this paper first image histogram is employed for detect the pixels which are selected for hiding a bit of secret data, then after a sequence of hiding a bit stream is determined by logistic chaotic map. Experimental results show that WICA not only demonstrates superior hiding effect, but also resists various typical attack. The obtained PSNR of the proposed method is approximately 54 which is proven our method excellence.
Index Terms— Data hiding, chaotic map, and entropy.
