Abstract

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 image. The least significant bit substation is used as an embedding method
