Image authentication based on salient regions of image

Image authentication is always a key issue in this era of multimedia technology. As we are very much familiar with all numerous hacking techniques along with the availability of image editing tools such as Photoshop, Stir Mark etc., Image security becomes a major issue, so this provides us with a lot of Research scope in the field of Image Authentication. Our paper presents a model to authenticate images transmitted across a non-secure channel. Therefore we propose the technique of image authentication based on the detection of Saliency Regions in the image and then forming a feature vector for the input image. Saliency regions are totally based upon the region of interest present in an image and it provides an accurate representation of texture features of the image.
