A Review on Watermarking Techniques of Digital Image

Digital content including photographs, audio, text, and movies can now be replicated, edited, and stored more easily because to the quick development of computer technology. Using a technique called digital image watermarking, it is possible to include secret copyright notices or other types of verification messages in digital audio, video, picture, or document files. This paper discusses the various techniques involved in the digital image watermarking. The artificial intelligence, deep neural network (DNN) and machine learning, deep learning technique and basic technology used for watermarking are discussed. In addition to the analyses indicated above, a watermarked image is put through a variety of attacks to determine its robustness, proving the success of the procedures mentioned earlier.
