Industrial Automatic Control Systems and Controllers Annotation << Back Model Construction of Steganographic Container in Video Files Based on the Least Significant Bit Method M.B. Bodrova, A.Yu. Ermakova The article presents the research of steganographic methods that provide the confidentiality of information during its transmission through public data channels. According to research it is selected the method of the least signifi cant bit and it is developed the model of steganographic container. To realize this process, it is proposed to use an original algorithm for embedding messages into an MP4 video file. Video file is proposed to be split into a specifi ed sequential series of frames in PNG format with embedded text message. The sequence of frames series is set by setting the frequency of splitting the video file into frames. The process of message embedding is carried out on the basis of the generated secret matrix. The necessity of using the original video file for the embedding of each subsequent message is emphasized. With the help of the developed software, a number of experiments were carried out with different sizes of MP4 video files. The value of pertinence for steganographic transformation in various cases have been calculated. Keywords: steganography, confidentiality, least significant bit method, pertinence.
