Abstract: The article provides an overview of the main methods of steganography, on the basis of which a new method was developed, consisting in embedding additional text (pseudo-information) in parallel with the transmitted message. An algorithm of this method has been developed. In this case, the frequency of the bit sequence was obtained in accordance with the generated pseudo-random numbers. In accordance with the algorithm, an application has been developed that allows the sender to encrypt and place the message in a container that is an image, and the recipient to determine the presence of the message and, if there is one, extract it. A computational experiment was also conducted, which showed that an image with a fairly large embedded text does not visually differ from the original image.
