In this paper, a novel data hiding scheme based on virtual window partition technique has been proposed to contribute the high payload capacity, low computation overhead and satisfied security. In addition, the proposed scheme has the advantage of stability because the payload capacity depends on a predetermined virtual window size. Some experimental results were performed to show that our proposed method has the superior both in payload and embedding quality in comparison to the data hiding methods based on the exploiting modification direction (EMD) embedding and the binary space partition (BSP) tree. The experimental result shows that our data hiding method based on virtual window partition technique can embed four bits per pixel without incurring any form of perceived distortion.
