Detailed Documentation
In this graduation thesis, we explore image digital watermarking schemes and their implementation using MATLAB alongside typical chaotic systems. We conduct an in-depth investigation of digital watermarking concepts and techniques, introducing commonly used digital watermarking algorithms with code implementation insights. Furthermore, we examine the fundamental principles of chaotic systems and present key chaotic system models, including their mathematical formulations and simulation approaches. By integrating digital watermarking with chaotic systems, we develop more secure and robust image watermarking solutions to meet modern information security demands. The implementation involves MATLAB programming for embedding/extracting watermarks using frequency-domain transformations (DCT/DWT) combined with chaos-based encryption for enhanced security through logistic maps or Lorenz systems.
