Abstract

Now a days with the wide use of multimedia is increasing to a large extent, the visual information that contains the high quality and low complexity digital images plays a very vital role in daily life applications such as satellite television, magnetic resonance imaging, computed tomography, geographical information systems and astronomy and many other areas. Main purpose of this paper is to investigate or develop new concepts to design digital image security system with good capacity and minimum a limited distortion in image quality. We investigate to develop the system that can accept all kinds of images that is grayscale images with the minimum complexity and highest PSNR (Peak Signal to Noise Ratio) value.Keywords: Multimedia, digital images, digital image security, steganography, grayscale images, PSNRCite this ArticleShashank Gupta, Rachit Jain.
