EDGE-Based Image Steganography

Steganography is a technique of hiding information in another data. In image steganography, the secret message is embedded inside one digital image. The most significant traffic comes from images on the internet, so hiding the data in images is most suitable. A digital image is represented as a grid of pixels, and generally, images have a large number of pixels, so a large amount of data can be hidden inside an Image. It is done so that there is less distortion with the image. The secret message is embedded in the image so that the human eye cannot detect it. Edge of Image means a sudden change in the image pixels. It captures the boundary present in some images, so edges are the most suitable place to hide the data in an image. In this paper, we will do some qualitative and quantitative analysis of various edge-based steganography methods, and we will compare this with the existing steganography methods available.
