A Novel Technique for Data Embedding Using Visual Saliency Map

Steganography is a technique in which secret message is hidden in some media like image file, audio file or video file. The objective of the steganography is to prevent the unauthorized user to estimate that certain secret communication is going on by concealing the very existence of secret message. As it is clear this thing involves deceiving the human visual system (HVS) to get an impression that some secret message is hidden in image or some other media file. Saliency model is one of the methods that generate a map corresponding to the attention region of Human Visual System. So Human Visual System (HVS) is a point of interconnection between two concepts - Steganography and Saliency Map. In this work we represent a method for data hiding in images based on saliency map.
