Audio Steganography in a Nutshell

Information hiding technique is a new kind of secret communication technology. Steganography has been proposed as a new alternative technique to enforce data security. A perfect audio Steganographic technique aim at embedding data in an imperceptible, robust and secure way and then extracting it by authorized people. Hence, up to date the main challenge in digital audio steganography is to obtain robust high capacity steganographic systems. Leaning towards designing a system that ensures high capacity or robustness and security of embedded data has led to great diversity in the existing steganographic techniques. In this paper, we present a current state of art literature on audio steganographic techniques and how it’s performed by different methods
