Perspective on a Hybrid Digital Watermarking Scheme for Securing Multimedia

Abstract

Technology dominates today's world, providing widespread, affordable internet access, leading to the rampant illegal sharing of digital media. Pirated versions of digital content are easily distributed globally through social media and mobile apps, violating copyrights and harming content owners' financial and intellectual property rights. The unauthorized copying, manipulation, and redistribution of digital media exacerbate piracy issues, necessitating robust authentication and copyright protection measures. Digital watermarking offers an effective solution to combat piracy by embedding additional information into digital content, ensuring authenticity and copyright ownership. Watermarking can be performed in the spatial or transfer domain. This paper outlines the lifecycle of a watermarking system, provides an overview of video watermarking techniques and their applications, and classifies these techniques based on human perception, detection methods, resistance to attacks, media type, and embedding techniques. It also discusses each approach's methods, uses, challenges, and key characteristics, presenting analytical findings from the past 15 years of literature. Finally, it discusses this study's remaining questions and suggests potential future research directions.
