Abstract

Steganography is the art and science of concealing information in content such as image, video and audio. This paper deals with achieving steganography using frequency domain technique, in particular, using discrete wavelet transform. The technique is a modified form of image data hiding technique which was proposed by Abdelwahab and Hassaan. The stego image is perceptually similar to the cover image and the quality of the stego-image remains same irrespective of the embedded secret image for a range of the size of the secret image.
