Abstract
The paper describes the implementation of the algorithm based on the idea that each frame has a unique from all other frames of the video frequency characteristics. In the processed frames of the video sequence and the received information about the characteristics, to select only those that meet the selected criterion. Rooms the received frames are passed to the module implementing a digital watermark. The article presents step-by-step description of the algorithm, an example of processing video data, the application software in the Matlab environment. It is proved that the algorithm works correctly.
Keywords: digital watermark, discrete Fourier transform, fast Fourier transform, steganography
