A Comprehensive Review on Optimization-Based Digital Image Watermarking Approaches for Copyright Protection
Abstract
The watermark must be both invisible and long-lasting. The ability to properly restore a watermark from recovered relevant content—which may also include a range of noises and compression effects—explains how robust a watermark is. Since digital data is added to a digital signal, the process of digitally watermarking an image is incredibly accurate. Watermarking is the technique of adding records into digital media, including text, still photos, videos, and audio statistics, without lowering the quality of the digital media as a whole. Another name for watermarking is digital fingerprinting. This technique is less energy-intensive and aids in preventing unauthorized statistics copying from multimedia networks. Watermarking has numerous applications, two of which are copyright protection and authentication. An overview of the many theories and research efforts being carried out on the topic of image watermark authentication is given in this paper. The patchwork signal as well as the watermarked sign. The host signal is the transmission that will have the watermark added to it. When employing a watermarking device, there are three steps involved: detection, attack, and embeddedness. A set of rules must first evaluate the host computer and the data that will be on it in order to generate a watermarked signal. Embedding records—also referred to as digital signatures or watermarks—into a digital signature in a way that makes it challenging for the records to be deleted is the process of digital watermarking. Another name for this process is digital watermarking. Virtual watermarks can be used to confirm the authenticity or integrity of a service signal and can also be used to uncover the owners' identity.

Relevance and Originality
The Research Article addresses the critical need for invisible and durable watermarks in digital media. By discussing the robustness of watermarks against various distortions and compression effects, it highlights the importance of maintaining digital content integrity. The exploration of watermarking, also known as digital fingerprinting, underscores its relevance in protecting copyrighted material and authenticating digital media. The focus on the theoretical and practical aspects of image watermark authentication provides a fresh perspective on the advancements and challenges in this field.
Methodology
The Research Article outlines the general process of watermarking, including detection, attack, and embeddedness, but lacks detailed methodological information. To improve the methodology, the paper should specify the techniques and tools used for embedding and detecting watermarks. Details on how different types of noises and compression effects are simulated would provide clarity on how the robustness of the watermark is tested. Including a step-by-step description of the experimental procedures would enhance the understanding of the watermarking process.
Validity & Reliability
The validity of the Research Article is supported by its focus on essential watermarking aspects, such as invisibility and durability. However, the reliability could be enhanced by including empirical data or case studies demonstrating the effectiveness of various watermarking techniques. Comparative analysis of different watermarking methods, supported by quantitative results, would provide a more robust evaluation and validate the claims made about the watermarking process.
Clarity and Structure
The Research Article provides a general overview of watermarking but could benefit from a more structured presentation. Breaking down the content into clearly defined sections—such as theoretical background, technical methods, and practical applications—would improve readability. Each section should be detailed, with specific subsections addressing the different aspects of watermarking, including the theoretical foundations, the process of embedding and detecting watermarks, and real-world applications.
Result Analysis
The Research Article discusses the theoretical aspects of watermarking but lacks detailed result analysis. To strengthen this section, the paper should present specific findings on the performance of various watermarking techniques under different conditions. Including data on how well different methods withstand distortions and attacks, and their effectiveness in maintaining watermark visibility and durability, would provide a comprehensive analysis of the results and their implications for digital media protection.
