Method of increasing the hidden channel band capacity for information processing technologies and transmission of video information resources
(2020) Dymchuk, V.
The urgency of the work is confirmed by the need to find new steganographic methods of concealing data. The purpose of the work is to develop a method for increasing the capacity of the information transmission channel in prospective automated intelligence processing systems. The analysis found that digital steganography methods have several disadvantages: low resistance to attacks, low amount of steganographic capacity, and are unstable when transmitting images and active attacks of the enemy, possible loss of data. The development of systems that use images and video to transmit data is forcing digital steganography techniques to protect data. The quality indices of the developed steganographic method were calculated. This method allows you to hide bits in image blocks and has a channel bandwidth 20% higher than other methods of hiding information. The developed method is resistant to known active attacks and steganographic analysis by the enemy. Recommendations for increasing bandwidth when using embedding methods in the conversion domain are defined.
