A secure audio steganography technique is introduced in this paper. Here modulo operator is used for hiding target string. The embedding as well as extracting process is of two steps which provides more robustness in this method. During preprocessing the hexadecimal equivalent of target string is calculated by taking four bits at a time. That increases capacity of cover media. Modulo operator is used during embedding and the adjustment is done in such a way so that the distortion becomes less which increases imperceptibility. The quality of experimental result is analyzed by SNR and also compared with standard LSB and HLLAS technique. Bits per sample is also calculated which shows more efficiency of the proposed technique.

This paper presents a new technique of embedding text data into an audio file using tone insertion method. The new technique generates two frequency f1 and f2 and inserts them into audio file in a suitable power level according to specific table (stego-table). The proposed technique aimed to increase the payload capacity of the audio file using two bits in the frame without increases the number of the inserted frequencies to four frequencies, as well as using another convoy frequency (CF) for specific pattern. The proposed method conceals the English text into the .wave audio. The performance of the proposed method has been checked by spectrogram, MSE and PSNR.

“…Several methods in the transform domain have been proposed in the literature as described next. To achieve the inaudibility, these methods exploit the frequency masking effect of the HAS directly by explicitly modifying only masked regions [7,[22][23][24] or indirectly [25,26] by altering slightly the audio signals samples.…”

The rapid spread in digital data usage in many real life applications have urged new and effective ways to ensure their security. Efficient secrecy can be achieved, at least in part, by implementing steganograhy techniques. Novel and versatile audio steganographic methods have been proposed. The goal of steganographic systems is to obtain secure and robust way to conceal high rate of secret data. We focus in this paper on digital audio steganography, which has emerged as a prominent source of data hiding across novel telecommunication technologies such as covered voice-over-IP, audio conferencing, etc. The multitude of steganographic criteria has led to a great diversity in these system design techniques. In this paper, we review current digital audio steganographic techniques and we evaluate their performance based on robustness, security and hiding capacity indicators. Another contribution of this paper is the provision of a robustness-based classification of steganographic models depending on their occurrence in the embedding process. A survey of major trends of audio steganography applications is also discussed in this paper.
