The paper investigated the possibility of using matrix encoding operations synthesized and based on the sum of modulus operations, for providing the numbering of steganocontainer blocks. In accordance with the results, new promising methods and recommendations are offered regarding to the use of matrix encoding based on the sum of modulus for numbering the steganocontainer blocks. The study of the statistic properties, developed methods by testing them with the help of test package NIST STS, is carried out. Conclusions on the effectiveness of the proposed methods of numbering are formed according to test results.
