The relevance of this research is driven by the increasing intensity and complexity of information attacks, in which video data has become one of the most vulnerable categories of digital information. Under contemporary conditions, traditional cryptographic tools do not provide complete protection against interception, substitution, and latent manipulations, which necessitates the use of steganographic protocols as an additional security layer. It has been demonstrated that covert embedding of service and control data into video streams enables preservation of information integrity and authenticity even under high loads and destructive impacts within network environments. The aim of this article is to develop a scientifically validated concept for enhancing video data security through integration of steganographic mechanisms into their transmission and processing under escalating information threats. This involves creating a multilevel security model that accounts for signal parameters, compression specifics, and operational modes of streaming systems. The research methodology is based on systematic analysis of steganographic concealment models, comparative evaluation of different algorithms’ resilience to transformations, compression, and packet losses, as well as structural and spectral analysis methods for video signals. Approaches for modeling covert data behavior in adaptive bitrate streams and methods for evaluating the effectiveness of integrated stego-cryptographic solutions were employed. The scientific novelty lies in comprehensive substantiation of the capabilities and limitations of steganographic protocols in high-load video systems, as well as in formulating a model for their adaptive integration with cryptographic tools. Patterns of influence exerted by video signal parameters, compression dynamics, and network characteristics on covert data preservation have been identified. It has been proven that combining steganographic and cryptographic approaches provides a synergistic effect in security enhancement. The conclusions establish that steganographic protocols can effectively strengthen video data protection through channel concealment, resilience to re-encoding, and preservation of control markers after network distortions. Scientific, technical, and algorithmic challenges in implementing such solutions have been identified, related to embedded data degradation during adaptive compression and high computational resource requirements. Recommendations have been formulated for adaptation and optimization of steganographic models based on video data type and potential attack profile.
