Audio steganography - SlideShare
https://www.slideshare.net/sharathkanjula1/audio-steganography-sharath
The basic spread spectrum (SS) method attempts to spread secret information across the frequency spectrum of the audio signal. This system is similar to a system which uses an implementation of the LSB that spreads the message bits randomly over the entire sound file. Unlike LSB coding, the Spread Spectrum method spreads the secret information over the …

A very interesting audio steganography method is the LSB (Least Significant Bit) algorithm. The least significant bit of the cover media is playing as a mask to the secret message. The modification made in such a way to the LSB bit should not be understood in the final stego object. Being an easy technique, a high level of security i

Steganography in Images Using LSB Technique
https://www.ijltet.org/wp-content/uploads/2015/02/60.pdf
The Least Significant Bit (LSB) steganography is one such technique in which least significant bit of the image is replaced with data bit. As this method is vulnerable to steganalysis so as to make it more secure we encrypt the raw data before embedding it in the image. Though the encryption process increases the time complexity, but at the same

steganography Image steganography Audio steganography- Audio steganography requires a. text or audio secret message to be embedded within a cover audio message. Due to availability of redundancy, the cover audio message before steganography and the stego message after steganography remains the same.

2015. TLDR. This paper proposes an audio steganography algorithm, for embedding text, audio or image based on Lifting Wavelet Transform (LWT) transform with modification of Least Significant Bit (LSB) technique and three random keys where these key is used to increase the robustness of the LSB technique.

Audio steganography is the scheme of hiding the existence of secret information by concealing it into another medium such as audio file. In this paper we mainly discuss different types of audio steganographic methods, advantages and disadvantages. KEYWORD Steganography, Cryptography, Audio Steganography, LSB. 1. INTRODUCTION
