Abstract:This paper propose a secure watermarking method based on the zero-watermarking framework, combining Arnold transformation, phase transformation, and advanced encryption techniques. The proposed method aims to enhance the concealment and security of the watermark. By applying Arnold scrambling to the images, the hiding capability of the watermark is improved, preventing unauthorized extraction. The image data is decomposed into overlapping blocks in the vertical and horizontal directions, and these blocks are e… Show more
