FPGA implementation of data hididng in grayscale imagesusing neighbour mean interpolation

Data hiding in one of the easiest technique to authenticate and resolve the copyright issues of multimedia data. This paper proposes a new VLSI architecture for data hiding in grayscale images using neighbour mean image interpolation technique, as this mechanism will have a minimum computation complexity. In this VLSI based data hiding process the secret digital signature is hidden in the host image and analyzed with the PSNR value and Payload capacity.
