Steganography is the science of communication that hides secret information inside the multimedia signal in such a way that the existence of secret information is concealed. In this paper image steganography is done. The text string is concealed in the cover image as a payload. The technique is based on pixel value differencing and pixel value sum. A secret key is used to control the message embedding process. At the receiver stego image is manipulated to get the text out of it. PSNR and capacity are used to measure the stego image quality.
