Steganography is the art and science of writing hidden messages in such a way that, apart from the sender and intended recipient, no one suspects the existence of the message, a form of security through the state of being unknown. The main two famous schemes used for image steganography are spatial domain embedding and transform domain embedding. The main aim of DWT is used to transform original image (cover image) from spatial domain to frequency domain. But here in our proposed work, 2-D DWT… CONTINUE READING
