RGB Image Watermarking System based on Cubic Spline Controller Key for Copyright Applications

Abstract

A novel mapping algorithm can be present in this paper depends on cubic spline algorithm as a key element for controlling the pixel position in the RGB image and use the proposed system with copyright application. Human Visual Systems (HVS) are conceded here , four samples are taken of the host image vector as well as interchange the position of cover image pixel with respect of another four sample of information (secret)image vector to construct a spline curve and completely exchange the cover image element( pixel). The slopes of this cubic spline curve, is employed for watermarking purpose. The achievement of the proposed method (technique) is empirically inspected and experimental consequences approve the efficacy of our method and its right robustness versus common watermarking intrusions (attacks) like Gaussian noise with the effect of Poisson noise, also salt and peppers noise with speckle noise and finally rotate 90o.
