Abstract

Text steganography is one of the areas of research and development, which allows to solve the problem of secret transmission or storage of information quite effectively. The article describes a steganographic method based on the use of text parameters, in which a .doc or .docx document is used as a container. The novelty of the considered method lies in the placement of a secret message based on the modification of such a parameter of text characters as a contour. The features of the use of the steganographic method in electronic publications are outlined in order to protect container documents from unauthorized copying or distribution. The developed software tool demonstrating the operation of the steganographic method is presented: the user interface of the application, the development technology, as well as the main structural elements of its architecture are described.
