Secure Steganography in Colored Images. A Novel Approach to Information Security

      Аннотация: The standard and conception of ‘‘What You See Is What You Get (WYSIWYG)’’ that we tend to encounter generally at the time of printing pictures or alternative materials is no longer precise and wouldn’t fool a steganographer because it doesn’t continuously hold true. Pictures may be quite, but we tend to see with our Human Visual System (HVS), therefore, they will convey quite simply a thousand words. The main aim of this study is to propose a steganography algorithm having strong resistance towards human visual system perception about hidden message in an image. To fulfill this aim saliency maps has been used as models for the steganography as to the authors knowledge it has never been used for steganography.
