The Trend Directive of Watermarking Techniques with Preliminary Estimates

Authentication is required to protect the content of the data because the owner never wants to degrade the quality of his data. Digital Watermarking is a fascinating study topic for research because it is an appropriate solution for claiming authorization. The interaction balance between imperceptibility, robustness, capacity, and safety must be maintained in developing an efficient and robust digital media watermarking system. And to ensure this, through the various domains, including spatial and transformation domains, have been hybridized to meet these required criteria, that are used for embedding in digital files. Also, reversible watermarking is employed to rebuild signals without data loss, increase embedding capacity, or reduce the system's perceptual impact.. During these articles reviews, we noticed some methods reached PSNR > 70 dB or to > +∞ dB, while embedding capacity reached 512 * 512 bbp.
