Abstract
One of the possible ways of hiding secret information is by using images. Images are the most common type of payload in terms of their availability and usage in steganographic applications. They are capable of hiding secret information because the human eye is less sensitive to minor changes in an image. In this paper, we propose a steganographic technique through Haar Discrete Wavelet transformation where data is hidden in the frequency domain. We apply the method on Computer Vision Group (CVG) image data on two scales (512 and 1024) and share its results in colour channels after embedding a different capacity of text. This allows us to observe the different behaviours of each image from the colour planes and the main measures of its evaluation.
