IMPROVEMENT OF THE STEGANOGRAPHIC METHOD FOR EMBEDDING FRAGILE DIGITAL WATERMARKS TO IMPROVE SECURITY OF STREAMING VIDEO FROM UNAUTHORIZED MODIFICATION

Abstract

In today's information society, one of the most popular multimedia data distributed on the Internet is streaming video. For this reason, it is important to ensure the confidentiality and integrity of video content, which is vulnerable to various types of malicious attacks. In particular, it is worth paying attention to the threats associated with the possibility of unauthorized modification, which may lead to copyright infringement, the spread of fake information, or other undesirable consequences. To solve this problem, the work proposes to apply steganographic methods that allow you to covertly embed watermarks in video files. In this regard, the possibility of protecting videos using fragile digital watermarks was analyzed. It is proposed to improve their embedding method by increasing the amount of information for embedding, improving the selection of containers, and using the HMACSHA-256 secret key function. The method with the proposed improvement was analyzed and compared with the existing analogue, the advantages were determined. The software implementation of the improved algorithm for embedding fragile digital watermarks was carried out.
