Audio steganography using dual randomness LSB method

Abstract

In the current internet scenario, secure data transmission is limited due to its attack made on data communication. So more robust methods are required to ensure secure data transmission. One solution to the above problem is Steganography. Audio steganography is concerned with hiding information in a cover (host) audio signal in an imperceptible way. Least Significant Bit (LSB) technique is the most simple and efficient technique used for audio steganography. But conventional LS B technique is easy to defeat. In this paper Dual Randomness LS B method is proposed which hides the secret message in randomly selected samples and in randomly selected bit. This method provides more confidentiality compared to conventional LSB method.
