Essay

The thesis is devoted to the construction of digital watermarking resistant to geometric attacks and attacks by linear smoothing filter. The method of region selection that is invariant to geometric transformations has been optimized by accuracy. This optimization based on the Fourier-Mellin transformation. The created digital watermark system constructing method uses information of the phase spectrum of a discrete Fourier transformation. Key words: computer steganography, digital watermark, robustness, geometric transformations, discrete Fourier transform, Furier-Mellin transform, linear smoothing filters.
