METHOD AND MATHEMATICAL MODEL OF STEGANOGRAPHICINFORMATION CONVERSION BASED ON MODIFICATION OF CONTOUROF TEXT-CONTAINER SYMBOLS
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 ste-ganographic method based on the use of text parameters, in which a .doc or .docx document is used as acontainer. The novelty of the considered method lies in the placement of a secret message based on themodification of such a parameter of text characters as a contour. The features of the use of the ste-ganographic method in electronic publications are outlined in order to protect container documents fromunauthorized copying or distribution. The developed software tool demonstrating the operation of thesteganographic method is presented: the user interface of the application, the development technology,as well as the main structural elements of its architecture are described.
