Steganography is mainly oriented around the undetectable transmission of one form of information within another. This paper shows a steganographic scheme based on Pixel Value Differencing (PVD) and Kekre's Multiple LSB Algorithms (KMLA). The Scheme based on KMLA+PVD method can embed secret data larger than the PVD and KMLA method. This technique is proposed to improve the image capacity. Experimental results show that there is a 8 % to 12% increase in the capacity along with imperceptibility of error given by the proposed method to that compared with PVD and KMLA.
