Abstract

This study deals with the analysis of a system for covert transmission of information in the form of digital watermarks (DWM) generated on the basis of signals with direct spectrum spreading. It has been shown that the use of additional information about audio signal in the coder makes it possible to significantly improve the characteristics of DWM system.
