Data Hiding using Edge-based Image Steganography

Neelam Jaiswal | Rekhansh Rao ^[3]

Abstract: This paper proposed a new method for data hiding within a digital image by using edge based steganography. Steganography is an art and science of hiding secret data by embedding message into an innocence looking cover media in such a way that no one can suspect its existence. In this proposed method we embed the text data in the edges of the digital image, Canny edge detection algorithm is used for detecting the edges of an image. Here amount of data plays an important role on the selection of edges i. e. higher the payload weaker selection of threshold value and for lower payload stronger threshold value will be selected. Then we use 2 LSB plane for embedding the text data on the pixels of the edges. And at the receiver end we extract the text data from stego image by simply applying the reverse process of proposed algorithm. Experiment result shows that we achieve high capacity and higher quality of stego image under HVS (human vision system) due to use of edge detection method.
