Abstract

This paper presents a new technique which uses pixel value differencing (PVD) method and least significant replacement method to hide data in the four first order levels decomposed by discrete wavelet transform (DWT). The simulation results show that the proposed technique gives high performance in terms of capacity, human visual quality and PSNR better than PVD+3LSB method, the Overlapping PVD method and Semi-hexagonal PVD method (SH-PVD).
