A Robust Image Steganography Using Multiple Edge Detection and Advanced Error Replacement Method
In this paper, the authors propose a Steganography method using the digital images. The art of embedding the data which is to be secured into the digital image is called as Image Steganography. Human visual system proved that the changes in the image edges are insensitive to human eyes. Therefore, they are using edge detection method in Steganography to increase data hiding capacity by embedding more data in these edge pixels. So, if they can increase number of edge pixels, they can increase the amount of data that can be hidden in the image. To increase the number of edge pixels, multiple edge detection is employed. Edge detection is carried out using more sophisticated operator like canny operator.
