WebAug 1, 2024 · Watermarking is a way to embed special information called a “mark” into digital objects such as images, videos, audio, or software so that the marked object has the same appearance or behavior of the original object. Moreover, it should be difficult for an adversary to remove the mark without damaging the object itself. WebDigital images are transferred with ease through the network. Many users are using the images without the knowledge of the owners. Therefore, a novel watermarking scheme is proposed to ensure copyright protection and authentication of images using cryptography techniques. Here, a quick response (QR) image is generated for a watermark image that … WebDec 30, 2024 · Cryptographic Watermark A watermark is a semi-transparent mark (a logo or text) that is embedded onto an image.
