WebThis paper depicts a crypto-watermarking scheme by combining watermarking and encryption to protect copyright of multispectral images and to provide security to the … The information to be embedded in a signal is called a digital watermark, although in some contexts the phrase digital watermark means the difference between the watermarked signal and the cover signal. The signal where the watermark is to be embedded is called the host signal. A watermarking system is usually divided into three distinct steps, embedding, attack, and detection. I…

WebOct 13, 2024 · This crypto-watermarking algorithm allows copyright protection and indexation. Our algorithm includes two steps. The first is insertion and it consists in inserting data into 3D meshes. This data is composed of a logo and a text describing the 3D object. WebWatermarking is a useful tool both for protecting ownership and for preventing unauthorized distribution of digital media. Software watermarking. In this work, we focus on software watermarking for cryptographic functionalities. WebWatermarking can be an answer to make secure image transmission.
