“…This method profits from the inability of person to visually differentiate colour shades that differ only in one unit so that the last bit of colour code is used to hide information. This method can be applied in raster monochromatic images as well as in the colourful images, where all image colour channels of RGB format are used [4][6]. …”

“…The point of this work is to give a brief overview of methods of hiding the existence of messages, to point out the advantages and disadvantages of steganographic algorithms, and to introduce the suggested algorithm of steganography which makes use of a particular method of steganography, using the least significant bits (LSB) of hiding media [3] [4].…”

The ambition to achieve covering of secret messages into another file is implemented in many steganographic solutions, but usually the message is covered only into one file. In this paper the mechanism based on the method of steganography, with use of many cover files, is described. Proposal of the algorithm, based on Last Significant Bit method of steganography, is also described. The main contribution of this work is in the proposal of multi-carrier steganographic solution along with its implementation in the software application.

“…It is based on embedding the bits of message in the least significant bit of the host which cause less effect in the host signal value and less error compared with the original signal. It allow large amount of data to be concealed within an audio file, [11] and usually not creates audible changes to the host but low robustness against attacks and signal processing modification. Fig 2, illustrates the LSB technique and how you can embed 'hi' message in the audio samples using this technique, [1].…”

Abstract-Steganography is the art of amalgamating the secret message into another public message which may be text, audio or video file in a way that no one can know or imperceptible the existence of message. So, the secret message can send in a secret and obscure way using steganography techniques. In this paper, we use the audio steganography where the secret message conceal in audio file. We use audio rather than image because the human auditory system (HAS) is more sensitive than human visual system (HVS). We propose 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 and without it no one can know the sort of secret message type, the length of the secret message and the initial position of the embedded secret message in LSB. The performance of our algorithm is calculated using SNR and we compare the values of our proposed method with some known algorithms.

“…We can increase the depth of the embedding layer from 4th to 6th and to 8 th LSB layers without disturbing the perceptual transparency of the stego audio signal, to improve the robustness of LSB technique against distortion and noise addition, [17] [19].Only bits at the sixth place of each 16 bits sample of the original signal are substituted with bits from the data [17] [18]. To reduce the embedding error, the other bits can be flipped in order to have a new sample that is nearer to the original one.…”

Today's internet community the secure data transfer is bounded due to its attack on data communication. Security of data can be achieved by implementing steganography techniques. All of the existing steganographic techniques use the digital multimedia files as a cover mediums to conceal secret data. Audio file use as a cover medium in steganography because of its larger size compare to other carrier's file such as text, image. So there are more possibilities to hide large amount of data inside digital audio file. Signals and digital audio files make suitable mediums for steganography because of its high level of redundancy and high data transmission rate. This is not easy to hide data in real time communication audio signals. In this paper we will survey the overall principles of hiding secret data in audio file using audio data hiding techniques, and deliver an overview of present techniques and functions and also discuss the advantages and disadvantages of different types of audio steganographic methods.
