— There are basically two approaches to embed a watermark in a multimedia element: spatial domain and transform domain watermarking. In the spatial domain, the watermark is embedded by modifying the pixel values in the original image. Transform domain watermarking is similar to spatial domain watermarking; in this case, the coefficients of transforms such as Discrete Cosine Transform (DCT), Discrete Fourier Transform (DFT) or Discrete Wavelet Transform (DWT) are modified. In this research work we used Radon Transformation (RT) in binary image watermarking. Experimental results show that this new algorithm gives very promising results for geometric attacks.
