The paper discusses various methods of steganography used to embed control information in digital images. The main focus is on the principles of operation, advantages and disadvantages of each method. Classical and modern methods such as LSD, FT, PVD, MPVD, DCT, S-UNIWARD, WOW, HUGO and Steghide are considered. Their resistance to steganalysis, steganographic capacity and computational complexity are analyzed. Understanding these methods makes it possible to increase the efficiency and safety of using steganographic techniques in various practical tasks.
