Abstract

In recent years, the field of digital image watermarking has garnered considerable attention due to its critical role in safeguarding broadcasting media. This technique serves as a powerful tool for ensuring the authenticity of content, monitoring media broadcasts, managing duplication control, and tackling a variety of related issues. Researchers have extensively examined digital image watermarking to address these challenges, making it a pivotal area of study. This paper delves into the concept of digital image watermarking, starting with an overview of its fundamental model. It then explores the primary requirements for effective watermarking systems and highlights their diverse applications. Additionally, the paper reviews key techniques and algorithms employed in watermarking, analyzes potential threats and attacks that such systems may face, and outlines the methods used to evaluate the performance and reliability of these systems.
