A Comprehensive Approach to Image Watermarking, Encryption and Steganography

Abstract: Steganography, water marking and encryption are widely used in image processing and communication. A general practice is to use them independently or in combination of two -for e.g. data hiding with encryption or steganography alone. This paper aims to combine the features of watermarking, image encryption as well as image steganography to provide reliable and secure data transmission .The basics of data hiding and encryption are explained. The first step involves inserting the required watermark on the image … Show more

“…They basically evaluate the DWT technique, its improvement, and its challenges and also result are analyzed on MATLAB tool by computing SSIM, PSNR and SSR values of extracted image. Sridhar, S. et al [19] combine the features of watermarking, image encryption in addition to image steganography to give consistent and protected data transmission .The fundamentals of data hiding and encryption are enlightened. The initial step entails inserting the mandatory watermark on the image at the best possible bit plane.…”
