Robust and High Capacity Audio Steganography using Modified Dual Randomness LSB method

Computer Engineering

In era of digital communication, to enforce data security new technique has been proposed is Steganography. Audio Steganography is a method of hiding information in order for data in an audio file to remain safe in such a manner that existence of secret message is concealed from third party. 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. To achieve this, message bits are embedded in random and higher Least Significant Bit (LSB) layer that increases robustness against noise addition and appropriate modification of bits in audio sample is performed to reduce the distortion.
