| Abstract: | The authors of this paper present a new method of digital watermarking of scalable vector graphics based on discrete fractional Fourier transform to protect its authority.The watermark is embedded in the discrete fractional Fourier transform spectrum of complex signal constructed by control points.Both high invisibility and robustness to some common manipulations and local modification,have been proved by experimental results. |
