Описание
Digital communication has become very popular due to the tremendous growth of internet. It is the widespread of digital assets which has made their security a major concern for everybody. Mostly, countermeasures of attacks on information security are achieved through encryption and data hiding techniques. This book presents state of the art data hiding methods for digital information with respect to images and network communication protocols. It has addressed both theoretical and practical aspects along with their implementation in MatLab. All data hiding approaches have focused on two main aspects; transparency and capacity of hidden data. This book proposes different comprehensive solutions to achieve high rates of data hiding, perceptual transparency, an edge based data embedding method with high (peak signal to noise ration) PSNR for images, where stego-image (carrying hidden data) has very high resemblance to cover-image (original image). For achieving high capacity, packet...
