Watermarking the Digital Image Using Hybrid Approach
Digital watermarking capabilities can now be improved in various ways, including resilience, imperceptibility, authentication, tamper-proofing, etc. This essay will concentrate on a novel method for optimally robustly incorporating a transparent digital watermark onto an original image (cover content). Depending on the methods used for error control, determine how to extract the high-quality digital watermark from the flagged image. How to protect the watermark from the impacts that the watermarked image’s processing produces. How to identify and rebuild the watermarked document’s tamper region image based on the cutting-edge watermarking method. We presented a hybrid strategy (which combines the DWT, SVD, and NN) to create a new intelligent model for digital watermarking that will be utilised to safeguard the copyright of the digital content and to find and recover the tampered/forged regions in the watermarked image. The experimental findings demonstrate the usefulness of the suggested system and its superior attack robustness.
