Intelligent processing: An approach of audio steganography

Abstract

“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 a technique used to transmit hidden information by modifying an audio signal in an imperceptible manner. The main challenge in audio steganography is to obtain robust high capacity steganographic systems. This paper provides implementation of two level encryption of user data by combining two areas of network security, cryptography and steganography. The combination of LSB technique with XORing method is described in this paper, which gives additional level of security. Varieties of techniques for embedding information in digital audio have been established. We will attend the general principles of hiding secret information using audio technology, and an overview of functions and techniques.
