DIGITAL WATERMARKING USING CHAOTIC MAPS

Abstract

In today's digital environment, the issues of copyright protection and information security are becoming increasingly important. One of the effective methods for protecting multimedia content is digital watermarking technology, which enables the identification and tracking of unauthorized use of digital files. At the same time, traditional watermarking methods have certain drawbacks, which encourages the search for new solutions. The aim of this research is to develop a method for implementing digital watermarks using chaotic maps, in order to enhance the resilience of watermarks against tampering and alterations. The subject of the research is the methods and technologies of digital watermarking (steganography) that utilize chaotic maps to improve the reliability, security, and invisibility of embedded information within digital objects. The object of the research is digital images (or multimedia objects) to which a watermark is applied using chaotic map-based algorithms, ensuring copyright protection, authentication, and data integrity. To achieve the set goal, the following tasks were undertaken: an analysis of key digital watermarking methods, an examination of the characteristics of chaotic maps and their potential in watermark creation, and a review of an algorithm for embedding digital watermarks using chaotic maps. This work explores the theoretical foundations of digital watermarking, analyzes existing embedding methods, and thoroughly investigates the potential application of chaotic maps in this domain. A methodology for using chaotic maps to generate keys and embed watermarks is proposed. The strengths and weaknesses of this approach are analyzed, and prospects for future research in this area are outlined.
