Steganography is the science of hiding secret data within any kind of medium such as image, video, audio and document. The two main category of image steganography are spatial-based embedding and transform-based embedding. In this paper an image steganography method in transform domain is proposed, which is based on discrete wavelet transform and a canny edge detection technique. The proposed method is an attempt to increase amount of embedded data into cover image and improve quality of stego
