Loginova E.V., Dubovikova E.Y. - The analysis of innovative capacity of Russian science in the context of national security ensuring pp. 17-69


Abstract: The research object comprises the factors determining the formation and realization of innovative capacity of the Russian science. The research subject is the set of economic connections and relations emerging in the process of implementation of innovative capacity of Russian science with the purpose of national security ensuring. The authors characterize the factors determining the resource component of the innovative capacity of Russian science. Special attention is paid to the analysis of rates characterizing the efficiency of scientific studies: the knowledge content of the GDP, the number of patent claims and grants, the number of created and applied advanced technologies, and the balance of technological trade with other countries, which help to define the level of realization of innovative capacity of Russian science. The authors work within the framework of the fundamental system-functional approach and apply the structural, historical-logical, complex, comparative, and monographical methods. The conclusions are based on the results of application of such specific analytical methods as classification, structuring, comparison, verification, ranging, indexing, and geographic extrapolation. The use of heuristic potential of these methods increases the validity of the authors’ assessments and the effectiveness of conclusions and recommendations. The authors conclude that scientific studies (and technologies based on these studies) define the innovative vector of the modern economy development, thus promotes the formation of conditions for national security ensuring in contemporary Russia. Such an approach allows interpreting scientific studies (in terms of their integration into the market relations system) as an active source of national security of Russia in a complicated geopolitical situation. 
Baltaev R.K., Lunegov I.V. - The method of increase of the transmitted information secrecy using the minimal possible change of the image pixels with its maximal filling with information pp. 52-59


Abstract: The research subject is the steganographic methods of data protection, able to hide not only the contents of the transmitted information, but also the very fact of transmission. The authors consider an important problem of creation of steganographic systems of information protection – the high secrecy of information transmission, which is the most important characteristic of such systems. The secrecy is understood not only as a visual or sound indistinguishability of a digital media file from the media file with embedded information, but also the statistical indistinguishability. The research methodology is based on the objective metric of image distortion, including the generally accepted figure – peak signal to noise ratio. The scientific novelty of the study consists in the proposed method of increase of the hidden transmission of information using the minimal possible image distortion with its maximal filling with embedded data. The authors analyze the most widely used steganographic systems of information protection. The authors ascertain that the most promising method of steganography is the method of direct spectrum broadening, since it has particular advantages compared with other methods. The problem of a high level of secrecy of information transmission, connected with the unacceptably high level of a container distortion upon the hidden data embedding is solved using this method. Based on the peak signal to noise ratio, the authors study the distortion of digital images with hidden information, embedded using different methods. The proposed method demonstrates the best results.
