“…Rahim et al (2014) also proposed a technique that hides the secret data in dual bits in the 4 and 1 LSB and makes modification to the other bits on the same sample. Moreover RohitTanwar 2014 presented a technique that used two bits (3th and 4th) for embedding and intelligent algorithm for altering the bits (2 and 5 ) to minimize the difference between stegosample and original audio file (Tanwar et al, 2014).…”

The aim of this study is to present different types of steganography in brief and to give a special attention to audio steganography technique because a huge number of audio files are exchanged through the networks. Nowadays the widening of attacker's abilities to access the private and public information transmitted over public communication system makes way for highlighting a tool that guarantees the secure transmission of hidden information. Information hiding was a common security term that mainly includes three techniques: cryptography, steganography and watermark. Cryptography was an ancient form that is used for confidential data. Steganography is a popular tool that uses digital medium to hide confidential data in innocent carrier such as image, audio, text and video. Steganography is in fact a complement for the earlier data hiding technique cryptography. However watermark is used for copyright protection. Audio steganography is technique that hides any type of secret data in cover audio file. This study also discusses the main requirements of steganography methods and how those methods achieve them. Furthermore it shows steganography domain and, carriers and information hiding techniques used in audio.

“…Hiding data in duel bits in the 4th and 1st LSB and modifying other bits has been suggested by [8] for more secure communication. [9] proposed 3rd and 4th bits for embedding the secret text and intelligent algorithms for altering 2nd and 5th bits for perceptual resemblance between cover file and stego file. [10] used advanced encryption standard to enhance the security of stego-file.…”

Audio steganography is one of the important methods to transit hidden information by modifying an audio signal in an imperceptible manner. In audio steganography, determining the best possible position for embedding the secret message with minimum alteration of the cover audio remains a challenging issue. In this technique we hide secrete text or audio information in a host message such that no one except the intended receiver is aware of its existence and prevents unauthorised access. Various techniques have been used for embedding information in digital audio. Least significant bit (LSB) technique is most commonly used technique for secure data transfer. This paper presents replacement of bits of samples to hide a sequence of bits of secrete text. The bits of samples are selected in a circular manner from LSB to MSB or vice versa. The results reveal satisfactory performance of the system and may be used for secure movement of data.

“…Also, there is an increase in capacity due to the use of Huffman coding. In [26], for each sample, the third and fourth LSB are replaced with the secret message and the second and fifth LSB are altered by using an intelligent algorithm so that the stego sample gets minimized. In [27], the audio samples are 16 bits.…”

In recent years, the wide applications of the wireless sensor networks have achieved great success. However, the security is a critical issue in many scenarios ranging from covert military operations to the organization of the social unrest. Because the traditional encrypting methods are easy to arouse suspicion, an adaptive audio steganography method is proposed. The method is based on interval and variable low bit coding, which can be applied to covert wireless communication. The interval for embedding secret messages into the audio file and the threshold in variable low bit coding are used for selecting the embedding location and embedding bits adaptively; thus the embedding capacity and the embedding rate are variable. Experimental results demonstrate that the proposed method has better performance in embedding rate and invisibility than other audio steganography methods.
