Robust Watermarking Technology in Digital Rights Management: A Comprehensive Analysis

The rapid advancement of information technology has made the massive creation, distribution, and consumption of digital content more convenient than ever. However, this convenience has also led to challenges in digital copyright protection. Robust watermarking technology, which as an effective method for digital copyright protection, embeds invisible watermarks into digital media to identify and track copyright ownership. This paper explores the application of robust watermarking technology in digital rights management (DRM), including its basic principles, implementation methods, and challenges. This paper analyzes the development background and framework of robust watermarking technology and discusses its applications in different types of digital media such as audio and images. Additionally, this paper examines the advantages and limitations of robust watermarking and proposes suggestions for its improvement. This study aims to provide theoretical and effective support for the digital rights management field and promote the widespread application of robust watermarking technology in protecting digital copyrights.
