摘要：we propose a new approach of designing watermarking on jpeg image using spread spectrum by creating noise on image. It is necessary to choose noise creation scheme for security .Stream cipher encryption algorithm is used in this paper to provide confidentiality for watermark. To make sure that each pixel in the image is contributed for watermarking Five stages of spread spectrum image watermarking is applied. So it is easy to maintain best watermarking on jpeg image. Noising and Embed watermark on compressed encrypted domain. Extract watermark and decompress decrypted domain then denoise algorithm used for getting real image
