A new method for audio steganography using message integrity

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 medium 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 steganography methods. In this paper we have proposed a new method of audio steganography incorporating encryption and pseudorandom sequence as a key. The secret data has been encrypted using RSA and pseudorandom sequence. The encrypted data is then embedded in the audio signals. The use of the pseudorandom sequence increases the complexity of the encryption and the RSA algorithm gives a very tight cipher design.

In present day to day life, effective data hiding methods are needed due to attack made on data communication. This paper presents the technique for the above requirement. In this proposed method, secret message in form of audio file is embedded within another carrier audio file (. wav) . In the transmitter end the output will be similar to the carrier with secret message embedded inside. The hacker will be blinded by the transmitted signal. At the receiver end the original message can be retrieved without any loss. The entire proposed system is simulated and their corresponding waveforms prove the effectiveness of this method.

In this paper In this paper, the proposed method hides the secret message based on searching about the identical bits between the secret messages and image pixels values. The performed computer simulation demonstrates the high efficiency of the proposed technique and the analytical comparative analysis indicates a number of advantages in comparison with the existed steganography software. For hiding secret information in images, there exists a large variety of steganography techniques some are more complex than others and all of them have respective strong and weak points The first to employ hidden communications techniques -with radio transmissionswere the armies, because of the strategic importance of secure communication and the need to conceal the source as much as possible. Nowadays, new constraints in using strong encryption for messages are added by international laws, so if two peers want to use it, they can resort in hiding the communication into casual looking data.

We propose a novel LSB-BMSE method that enhances LSB audio steganography. It uses an innovative mechanism, Binaries of Message Size Encoding (BMSE), to embed a secret message after hiding its size in random samples. First, the secret message is compressed using Huffman coding, then encrypted by AES-128. The audio cover is split into number of blocks depending on secret message size. A secure key BMSE , output from the BMSE mechanism, is used to embed the secret message in random blocks and bytes adaptively according to its size. It is implemented using MATLAB and standard parameters: Perceptual Evaluation of Speech Quality and NIST Statistical Test Suite were used to measure imperceptibility between cover & stego audios and randomness of BMSE mechanism respectively. The fidelity was tested using Mean Square Error, Peak Signal to Noise Ratio and Signal-to-Noise Ratio. Comprehensive experiments on widely used metrics demonstrate that LSB-BMSE significantly surpasses existing methods in terms of hiding capacity and imperceptibility. Moreover, LSB-BMSE shows resistance to brute force attacks and statistical analysis. Although it was robust towards re-sampling attacks, nevertheless was not vigorous towards noise nor LSB attacks. The key BMSE complies with Kerckhoff's principle and exhibits avalanche criteria. The tested proposed LSB-BMSE proclaimed its effectiveness. INDEX TERMS Adaptive Steganography, Audio Steganography, Hiding Information, Least Significant Bit (LSB) I. INTRODUCTION T O increase the security of secret messages in an open system environment, it is very important to hide two properties of the message, its context and existence in order to cover it from unauthorized recipients. Steganography is a science of invisible or secret communication [1-3]. Audio steganography is the art and science of hiding digital data such as text messages and binary files into audio files such as WAV, MIDI, AVI, MPEG and MP3 files [3-5]. The reason for considering audio as cover media is the representation of amplitudes in real number format which causes very small distortions after embedding the bits of target data. An efficacious steganography scheme should meet the three requirements, namely capacity, transparency and robustness. Capacity is the maximum amount of secret information that can be embedded in a file [9]. Imperceptibility indicates that a steganographic system is perfectly secure if the statistics of the cover and the stego files are identical. The last requirement is robustness which denotes the resistance of stego file to various attacks and its capability to retrieve secret message with a minimum error [10-13]. These parameters are conflicting as the increase in hiding capacity leads to degradation in the robustness of secret message and transparency of stego file and vice versa. Thus the trade-off among them is

A technique, in which readable form of secret message is converted to an unreadable form to keep the secret message undetectable easily by the any unauthorised access or adversary, is known as cryptography. Cryptography means simply jumbling sequence of original message or altered the sequence of message. Cryptanalysis is the technique at which the secret message is converted from unreadable format to readable format without knowing the techniques how they were converted from readable format to unreadable format. Audio steganography, where the audio file (.wav) file is used for the secret data embedding. Audio signal bits are modified with the secret bits as imperceptible manner.

One of the things that must be considered when establishing a data exchange connection is to make that communication confidential and hide the file’s features when the snoopers intercept it. In this work, transformation (encoding) and steganography techniques are invested to produce an efficient system to secure communication for an audio signal by producing an efficient method to transform the signal into a red–green–blue (RGB) image. Subsequently, this image is hidden in a cover audio file by using the least significant bit (LSB) method in the spatial and transform domains using discrete wavelet transform. The audio files of the message and the cover are in *.wav format. The experimental results showed the success of the transformation in concealing audio secret messages, as well the remarkability of the stego signal quality in both techniques. A peak signal-to-noise ratio peak signal-to-noise ratio (PSNR) scored (20-26) dB with wavelet and (81-112) dB with LSB for cover file size...

Steganography conceals the existence of secret information, while cryptography hides the meaning of the confidential information. Therefore, combining these two can provide a secure communication between a sender and a receiver. This article proposes a double-layer message security scheme where cryptography is the first layer and steganography is the second layer. AES-256, Blowfish, or a Logistic map is used in the cryptography layer. The LSB substitution technique is used for the steganography layer to embed a secret message inside cover audio. The LSB substitution technique is applied by alternating between the left and the right channels, respectively. Performance of the proposed schemes is evaluated in terms of a hearing test, running time, embedding capacity, waveform plots, as well as a large number of statistical, time-domain, and frequency-domain metrics. Furthermore, a comparison between the proposed scheme using AES-256 and its counterparts from the literature is also provided. The numerical results show that the proposed schemes exhibit very good performance.

we can communicate with each other by passing messages which is not secure, but we make a communication be kept secret by embedding the message into carrier or by special tools such as invisible ink, microdots etc. Steganography is the science that involves communicating secret data in an appropriate carrier which is used from hundreds of years. In digital age new techniques of hiding the data inside the carrier are invented which are known as digital steganography. Nowadays, the carrier of the message can be an image, audio, video or a text file. In this paper we have purposed a method to enhance the security level in audio steganography and also improve the quality by making 2-level steganography.

Steganography is a science to hide information, it hides a message to another object, and it increases the security of data transmission and archiving it. In the process of steganography, the hidden object in which data is hidden the carrier object and the new object, is called the steganography object. The multiple carriers, such as text, audio, video, image and so can be mentioned for steganography; however, audio has been significantly considered due to the multiplicity of uses in various fields such as the internet. For steganography process, several methods have been developed; including work in the temporary and transformation, each of has its own advantages and disadvantages, and special function. In this paper we mainly review and evaluate different types of audio steganography techniques, advantages and disadvantages.

Security is the major challenge of digital communication. Cryptography and steganography are two common methods available to ensure security.Steganography is the term used to hide secret messages in a text, audio or image file.Modern methods are necessary to keep information secret and to protect it from the growing danger of external hackers.Steganography makes it possible to transmit information through communication channels. In this work we have focused on digital audio as the carrier and cover file. Audio steganography is a method to safely conceal a secret message into an audio cover file in various ways.The audio files are in the standard WAV format, in which the secret message is embedded by using the LSB algorithm. The secret message gets encrypted using the RSA algorithm before the embedding process. This combination is providing two level security to the secret message to be transmitted.
