WebCryptography and image watermarking are domains that provide multiple security services, such as authenticity, integrity, and privacy. In this paper, a digital image watermarking technique is proposed that employs the least significant bit (LSB) and canny edge detection method. The proposed method provides better security services and it is ... WebAbstract. A cryptographic watermarking scheme embeds a message into a program while preserving its functionality. Recently, a number of watermarking schemes have been proposed, which are proven secure in the sense that given one marked program, any attempt to remove the embedded message will substantially change its functionality.

WebHowever, we see some of the solutions are better than others. For example, the solution with 01, and 11 as watermark, they both have five letters as the solution, and, however, the other two have nine literals. This is one of the challenges for watermarking, which is known as fairness, and we will talk about this later. Let's see another example. WebA cryptographic watermarking technique for multimedia signals 269 potentially detectable. While in frequency domain approaches, the watermark signal is embedded into the spectrum of the host image generated through the Fourier transform. The embedded watermark is therefore distributed to the entire host image following the inverse Fourier ...
