Digital watermarking is a technique used for copyright protection and authentication by embedding a distinctive identifier into digital content. The key concept involves extracting this hidden identifier-such as a signature or logo-from a document in which it was embedded before transmission. This book presents a successful implementation of double host image watermarking using a single watermark image, a method not previously achieved. In all proposed models, the identifier image is divided into two separate channels and embedded into two different cover images. During extraction, both…mehr

Produktbeschreibung
Digital watermarking is a technique used for copyright protection and authentication by embedding a distinctive identifier into digital content. The key concept involves extracting this hidden identifier-such as a signature or logo-from a document in which it was embedded before transmission. This book presents a successful implementation of double host image watermarking using a single watermark image, a method not previously achieved. In all proposed models, the identifier image is divided into two separate channels and embedded into two different cover images. During extraction, both concealed images are retrieved and combined to reconstruct the original identifier. The models were simulated using MATLAB software and demonstrated superior performance compared to state-of-the-art approaches.
