Abstract

This paper shows that a steganographic scheme bas e d on Wu e t al . ' s pi x e l -value differencing (PVD) and least-significant-bit (LSB) replacement method is too conformable to the LSB approach. Their PVD+LSB method can embed secret data larger than the PVD method, however, it is detectable by Fridrich et al.' s method but PVD method is not. Some of the shortcomings of the PVD+LSB method are shown in this paper. At the same time, some techniques are proposed for improving the image quality of the PVD+LSB method without sacrificing the capacity. All proposed techniques are demonstrated by experimental results. Keywords: Pixel-Value Differencing; LSB; Steganography
