In this paper, a new modification of spread spectrum imagesteganography (SSIS) is presented. The proposed modification of SSIShides and recovers a message of substantial length within digital imagewhile maintaining the original image size and dynamic range. Anembedded message can be in the form of text, image, or any otherdigital signal. Our method is based on CDMA SSIS technique. To increasethe information capacity of the stego channel and decrease a distortionof a cover image, a new modification of CDMA using a codebook (in thefollowing referred to as Codebook CDMA (CCDMA)) is suggested.
