Hybrid Domain Steganography for Embedding DES Encrypted QR Code Using Random Bit Binary Search

Abstract

Steganography is a technology used for hiding the digital information into an electronic document so that it can be used only by the authorized entity and not available to trespassers. In the recent era, QR code is used versatile in all the applications. The data capacity of QR code is more as the information is codified in the form of image. Image Steganography can be achieved in spatial, transformation or hybrid domain. In this paper, a novel hybrid domain Steganography is employed for embedding encrypted QR code image in Source Image to get stego Image using Discrete Wavelet Transforms and Random Bit Binary Search (DWT - RBBS) technique. The information is encrypted using DES encryption algorithm and is codified to QR code image. This QR code image is then embedded into the source image using DWT-RBBS technique resulting in multiple level of security
