EVALUATION OF SIGNAL MASKING BY A TWO-COMPONENT STEGANOGRAPHIC SYSTEM IN WINDOWED INFORMATION PROCESSING
M. V. Shakurskiy, O. A. Karaulova Povolzhskiy State University of Telecommunications and Informatics
Annotation: When considering digital systems for transmitting information in real time, in most cases, the transmission of information in blocks with a given delay time is implied. In this case, the delay determines the size of the sampling window. The article deals with the issues of masking an embedded message into an uncom-pressed audio signal with a variable size of the sample being processed.
Keywords: steganography, sound, masking of information, two-component steganographic system, real time system.
