A Comprehensive Survey on Image Watermarking and Secret Data Hiding for Mobile Communication

Digital media protection and unlawful redistribution have become major challenges in the digital age. One of the most important methods for protecting copyrights, verifying ownership, and stopping software piracy is watermarking software. There is an enormous amount of digital data that needs to be protected as a result of the development of communication technologies. A technique for concealing private information in an original signal while improving the signal's overall performance is watermarking. Another topic that is gaining attention in the context of digital picture watermarking is multiple watermarking, whereby more than one watermark is introduced into a single multimedia product. Only a digital watermarking technique is used to covertly encode a brand or copyright statement in the medical image. Numerous academics have created ANFIS to add a watermark on the primary (cover) image. Regions of interest (ROIs) can be used to choose the embedding locations during watermarking. To decrease the distinction between unique and watermarked unaccompanied values, an optimized-quality component is provided. First, a mould form performance index called the height signal-to-noise ratio (PSNR) is explained. The suggested method achieves excessive values for normalised contextual connection (NCC) for the recovered watermark and produces an excessive top signal in terms of PSNR for watermarked images.
