The proposed algorithm is used to obtain partial turning resistance. The traditional method of implementation of the watermark is described. The proposed method for the implementation of the watermark is described. In the proposed method, the Arnold transform is excluded and the coefficients at which the watermark is applied are changed. The results of the comparison of the traditional and the proposed methods for the introduction of watermark are presented. The cross-correlation coefficient (between two square matrices) was calculated. The proposed method has characteristics in terms of resistance to turns and reflections higher than the traditional one.

Keywords:image processing, digital watermarks, discrete wavelet transform, discrete cosine transform, frequency domain.
