Abstract:
In order to improve the robustness,invisibility and security of digital watermark,this paper puts forward the fractional Fourier transform(FRFT)digital watermarking algorithm based on discrete cosine transform(DCT)and discrete wavelet transform(DWT).This method uses the focus of DCT,multiresolution of DWT and time-frequency of FRFT,the watermark information is embedded into the carrier image very well.At the same time,we use Arnold transform on the watermark encryption,security has been improved more.MATLAB simulation shows that the algorithm has good security,robustness and invisibility.
