Secure Watermarking in Fractional Wavelet Domains

Abstract

This paper proposes a novel technique for securing and preventing the misuse of images by digital image watermarking. The technique is based on a hybrid approach employing the Wavelet Transform (WT), and the Fractional Fourier transform (FRT) termed as the Fractional Wavelet Transform (FWT). We present experimental evidence to establish the advantages of this scheme over other watermarking schemes when subject to attacks such as noise and compression.
