An Overview on Research Trends, Challenges, Applications and Future Direction in Digital Image Watermarking

Digital data including photographs, audio, and video are now readily available because to the development of the Internet. The ease of access to multime- dia raises concerns about ownership identification, authentication of content, security, and copyright protection. Here, we talk about the idea of digital pic- ture watermarking with an emphasis on the method utilized for embedding and extracting the watermark from images. This paper also presents a complete classification of digital watermarking along with its fundamental properties, such as visual imperceptibility, resilience, capacity, and security. Additionally, we have covered the most recent uses of digital watermarking in the fields of healthcare, distance learning, electronic voting, and the military. The robust- ness is assessed by looking at how image processing assaults affect the content that is signed and the recoverability of the watermark. The thorough survey that is offered in this study, in the opinion of the authors, will aid brand-new scholars in learning more about this area. Additionally, the comparative study can spark suggestions for how to enhance the methods already outlined.
