Obviously due to the increased development of information technology, today methods of mathematical modeling and probabilistic and statistical processing are used globally. For example, there is often a need for systems with high demands on the structural secrecy, confidentiality and reliability of the information that can protect against unauthorized reading and modifying data.

It's also, for example, the necessary declarations study confirms the trend of high growth needs in the task of processes misstatements digital media. Which is explained random overlapping signals in the same frequency band with the increasing use of digital media information.

Objectives for our studies:

1. Representation of probabilistic models of information processes;
2. Statistical study models;
3. Development of recommendations on the use of models.

Implementation of these studies would allow to form an idea of the possible methods of improving the program models, for example, information distortion of digital media in terms of probabilistic and statistical analysis.
