This article deals with brief review of modern steganography algorithms. Three algorithms were considered. The first one was an algorithm, working with digital signal. It was described with LSB method in this article. The second algorithm was “sealing-in” of hidden information. It was presented with DWM method in the article. And last but not least algorithm was connected with the features of file formats. Pros and cons of each algorithm were presented. It helped to fully understand these algorithms.
