Steganography in coloured images using wavelet domain-based saliency map

International Journal of Information and Computer Security (IJICS), Vol. 5, No. 3, 2013

Abstract: Steganography is a process that involves hiding a message in an appropriate carrier for example an image or an audio file. Many algorithms have been proposed for this purpose in spatial and frequency domain. But in almost all the algorithms, it has been noticed that as we embed the secret data in the image certain characteristics or statistics of the image get disturbed. To deal with this problem, we have another paradigm named as adaptive steganography which is based upon some mathematical model. For this mode of steganography, we have already proposed the use of saliency map as mathematical model for hiding the secret data. Saliency map is a feature map that highlights the attention region of an image. In this work, we will propose a technique which uses saliency map as a model to hide the secret bits of data.
