ABSTRACT

The Streganography method for digital images has to insert secret data into the image without imagedistortion. Side match method is that size of secret data is calculated by difference of embedded pixel valueand mean value of side pixels. And the secret value is embedded into the embedded pixel. Therefore, themore secret data increases, the more image distortion increases, too. In this paper, we propose theenhanced method that calculates embedded pixel value by difference of secret value and mean value of sidepixels. In proposed method, more secret data is embedded and image distortion has to decreases.
