While encrypting information with color images, most encryption schemes treat color images
as three different grayscale planes and encrypt each plane individually. These algorithms …

The secure transmission of images is a critical aspect of information security, especially in
an era where digital communication is ubiquitous. Image encryption, leveraging the …

Data hiding studies that using the images as carriers are still remain popular. One of the
important reasons for this case is that it is easier to manipulate images than other carriers. In …
