An Effective and Safe Method for Digital Image Watermarking That Uses RDWT Algorithms with SVD and Firefly

Abstract

Digital watermarking is the process of concealing digital copyright information in digital content, to enable copyright protection and stop unauthorized distribution. The process of undetectable digital data embedding in the host audio stream is known as digital audio watermarking. One of the best approaches for embedding a picture into another image is image watermarking. Despite the fact that there are several methods available for watermarking SVD, Firefly is the most effective method for achieving the greatest outcomes. Watermarking is generated by SVD, and firefly aids in both encryption and watermarking. The most effective method for creating safe watermarks is to combine cryptography and watermarking. While there are several scaling factors that can be applied to fireflies, multiple scaling factors are used in this study. This study measures the Structure Similarity Index Measure (SSIM). Furthermore, the watermarked image undergoes standard processing methods such as sharpening and smoothing, and is subsequently encrypted using Firefly.
