Streszczenie: Digital content can be created or transformed using vector or raster graphics. Rasterization of the text fragments of the a birth content leads to the blurring of the contours of the letters and the transition of color into a gradient. This feature of the vector-raster transformation can specified a way to solve applied problems based on steganographic methods, creating secret channels for storing or transmitting data. To increase the throughput and steganographic stability of such channels, it is advisable to introduce elements of the deposited message into the symbols of the container document, relying on certain spatial and geometric parameters and properties of these symbols. The article presents the results of the analysis and classification of the letters of the Russian alphabet according to several statistical features. In accordance with this, all letters are conditionally divided into three groups. The results of the analysis of pixel distributions for displaying letters when converting content according to the PDF – PNG scheme can be used to develop steganographic methods by creating secret channels for storing (digital watermark) or transmitting information. The choice of appropriate symbols belonging to different groups for the placement of secret information not only increases the bandwidth of the channel and reduces the effectiveness of visual or other attacks on the steganocontainer, but also will simplify the algorithms for the introduction (extraction) of secret information.
