Abstract
The increasing reliance on digital media and the rising threat of unauthorized manipulation and distribution have underscored the critical need for advanced watermarking techniques. Robust and reversible watermarking has emerged as a dual-purpose solution, offering both content authentication and data recovery. This review explores recent advancements in this field, focusing on novel methodologies and algorithms that enhance watermark robustness, imperceptibility, and reversibility. The paper delves into the integration of emerging technologies, such as machine learning, blockchain, and hybrid cryptographic systems, to overcome existing challenges in dynamic environments. Additionally, it examines domain-specific applications, including healthcare, copyright protection, and forensic analysis, where the demand for reliable watermarking is paramount. By evaluating current trends, comparative analyses, and potential research directions, this review aims to provide a comprehensive understanding of how enhanced watermarking techniques can revolutionize digital security. The insights offered in this paper will guide researchers and practitioners in developing innovative solutions for safeguarding digital content in the evolving technological landscape.
