Abstract :
The steganography is the embedding of secret message in the cover image for covert communication. In this paper we present a high capacity data embedding using colour palette decomposition (CPD) in which the payload is embedded into the cover image as an index of shifted centroids which is derived from the clustering of the cover image to derive the stego image. The error control coding is applied to stego image to increase PSNR, capacity and security. It is observed that our algorithm has higher PSNR and capacity in comparison to earlier works
