“…Results show that this method achieved high capacity, small compression rate, high speed in the execution time for embedding/reconstruction and high quality of reconstructed image (Chang and Nguyen, 2014). Pan et al (2015) also proposed a reversible data hiding technique that hides secret bits into image.It uses side-match distortion to sort the VQ codebook to make the index very close to its neighbour and use the residual value between indexes for hiding that it is obtained from XOR operation. It preserves the quality of the reconstructed cover image and increases the hiding capacity (Pan et al, 2015).…”

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.

“…The simplicity in implementation and low cost of the operations are two important properties of the spatial domain techniques, but the drawback of this approach is low robustness against signal processing and geometric attacks. Instead, transformed domain techniques are usually employed for robust watermarking to ensure resistance of the watermarked image against the mentioned attacks [13,39,40]. Several examples of transformed domain techniques are the Discrete Cosine Transform (DCT), Singular Value Decomposition (SVD), Discrete Wavelet Transform (DWT) and Discrete Fourier Transform (DFT).…”

In this paper, an analysis on hybrid Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) for image watermarking is carried out to investigate the effect of a deeper level of the SVD on imperceptibility and robustness to resist common signal processing and geometric attacks. For this purpose, we have designed two hybrid watermarking schemes, the first one with DWT and first level of SVD, whereas, in the second scheme, the same design is employed with a second level of SVD. In this experiment, a comprehensive analysis is performed on the two designed schemes and the effect of robustness and imperceptibility is compared in the first and second levels of SVD in each DWT sub-band. Having analyzed more than 100 medical and non-medical images in standard datasets and real medical samples of patients, the experimental outcomes show a remarkable increase in both imperceptibility and robustness in the second level of SVD, in comparison to the first level. In addition, the achieved result shows that the SVD2 scheme offers the highest imperceptibility in the LL sub-band (more than 60 dB on average PSNR), with satisfactory robustness against noise attacks, but less persistence in some geometric attacks such as cropping. For the HH sub-band, strong robustness against all types of tested of attacks is obtained, though its imperceptibility is slightly lower than the achieved PSNR in the LL sub-band. In HH sub-band, an average growth of 5 dB in PSNR and 2% in NC can be observed from the second level of SVD in comparison to the first level. These results make SVD2 a good candidate for content protection, especially for medical images.

“…According to Ki-Hyun Jung [13] the highest embedded capacity must be within the acceptable image quality and also the capacity of the embedding is restricted with the lower distortion of the image [11,14].The easiest way to hide data is to embed cipher texts by hiding bitmaps in colour picture [14]. Here the number of bits that is being traversed is perceived.…”

Abstract-The idea of secretly sending information has seen its importance as old as the communication evolved itself. Steganography is nothing but to embed the secret information in an image, audio or in a video. The sensitive image that contains the secret information is called the stego-image. This information hiding makes sure that only the sender and receiver can suspect the existence of secret information in the image. The main advantage of the steganographic technique is that the secret information does not draw attention (remains subtle). In this way the hidden information is highly secured. Shannon-FanoElias is one technique of embedding the secret information where the embedding of secret string is done by generating a code word for each character in a string. By this technique high degree of data encryption is made possible. In order to make sure that the stego images are not being easily intruded, a check of the quality of stego images is done by calculating the Peak Signal To Noise Ratio (PSNR) and Mean Square Error (MSE). This paper provides a simple avant-garde review and the various analysis of the Shannon-Fano-Elias algorithm with some standards and general rules unfolded from various analysis.
