An Approach of Robust High Capacity Audio Steganography and Cryptography Using LSB Algorithms

Abstract

Increased use of electronic communication has given birth to new ways of transmitting information securely. Security has its importance and application in wide area. It is a measure of human negligence, in desire to seize the latest technological inventions. This measure may have adverse effect on human perception to the deployment of application, which needs serious concern in terms of security. Audio steganography is the science of hiding some secret text or audio information in a host message. The main challenge in audio steganography is to obtain high payload and robustness. A wide variety of techniques are existing such as LSB, Parity coding, phase coding for audio steganography. Here, a new approach with two level encryption of user data by combining cryptography and steganography is proposing to achieve high payload capacity and robust technique for Embedding information in Digital Audio data.
