Analysis of the characteristics of the algorithms for embedding watermark against the background of attacks and interference in communication channels

Abstract

In this paper, an overview of the algorithms of concealing information in the video, which can be used to protect copyright, has been made. A new algorithm is proposed that allows increasing the bandwidth and stability of existing methods by increasing the number of coefficients for embedding and application of noise immunity codes. An effective way to resolve copyright issues is to provide authentication through the introduction of digital watermarks embedded with steganographic algorithms. The scientific novelty of the work is that the theory of embedding information in video files has been further refined by taking into account factors that arise in communication channels, such as attacks and interference. This enhancement makes it possible to increase the efficiency of the system of transmission of hidden (embedded) information by interference channels through the use of fault-tolerant codes and the selection of the optimal latency criteria of transmission parameters (including the embedding threshold). The practical significance of the work is determined by the fact that most of the copyrighted information has to be transmitted by the communication channels and, in order to ensure an adequate level of effectiveness, the parameters of the copyright protection system must be consistent with the parameters of the communication channel.
