Aiming at the problem that data hiding algorithm of high efficiency video coding (HEVC) has great influence on bit rate and visual quality, an information based intra prediction mode matrix is proposed. Firstly, 8 modes are selected from 4×4 luminance blocks in I frame to embed hidden information. Then, Least Significant Bit (LSB) used modulate LSB last mode. Finally, modulated block re-encoded...

In this paper, we propose a new method for the detection of LSB embedding in JPEG images. We are motivated by a need to further research the idea of the chi-square attack. The newmethod simply use the first-order statistics of DCT coefficients, but is more powerful to detect the random embedding in JPEG images. For evaluation, we used versions of Jsteg and Jphide with randomized embedding path ...

The communication system can be achieved based on steganography in stream media such as LSB based (Least Significant Bit) methods are the most popular strategies. The steganography algorithm for embedding data in the active and inactive frame audio streams encoded by XOR source codec. This is used extensively in channel. Then LSB embedding in the secret information flat regions of the speech. T...

As well-known, it is hard to detect LSB matching steganography when cover images are scans of photographs, which usually have high-frequency noise. This paper proposes a novel steganalysis method for this issue by making use of the following two facts: One is the local maxima of an image histogram decrease and the local minima increase after LSB matching steganography. As a result, the area bet...

In this paper, a new steganographic method that preserves the first-order statistics of the cover is proposed. Suitable for the passive warden scenario, the proposed method is not robust to any change of the stego object. Besides the relative simplicity of both encoding and decoding, high and adjustable information hiding rate can be achieved with our method. In addition, the perceptual distort...

Least Significant Bit (LSB) technique is the earliest developed technique in watermarking and it is also the most simple, direct and common technique. It essentially involves embedding the watermark by replacing the least significant bit of the image data with a bit of the watermark data. The disadvantage of LSB is that it is not robust against attacks. In this study intermediate significant bi...

For watermarking of the digital grayscale image its Gray planes have been used. With the help of the introduced representation over Gray planes the LSB embedding method and detection have been discussed. It found that data, a binary image, hidden in the Gray planes is more robust to JPEG lossy compression than in the bit planes.

ABSTARCT: Communication over the internet is facing some problem such as data security, copyright control, data size capacity, authentication etc. Here we introduce a novel scheme for separable reversible data hiding in encrypted domain in which we use image as a cover medium. This paper illustrates the various objectives of implementing separable reversible data hiding technique. The separable...

In this paper we present a new accurate steganalysis method for the LSB replacement steganography. The suggested method is based on the changes that occur in the histogram of an image after the embedding of data. Every pair of neighboring bins of a histogram are either inter-related or unrelated depending on whether embedding of a bit of data in the image could affect both bins or not. We show ...
