This paper proposed an universal steganalysis program based on quantification attack which can detect several kinds of data hiding algorithms for grayscale images. In practice, most techniques produce stego images that are perceptually identical to the cover images but exhibit statistical irregularities that distinguish them from cover images. Attacking the suspicious images using the quantization method, we can obtain statistically different from embedded-and-quantization attacked images and from quantization attacked-but-not-embedded sources. We have developed a technique based on one-class SVM for discriminating between cover-images and stego-images. Simulation results show our approach is able to distinguish between cover and stego images with reasonable accuracy.

Protecting the security of sensitive information has become a matter of great concern to everyone. data hiding technique solves the problem to some extent, but still, some shortcomings remain for researching. To improve the capability of hiding huge data file in disk with high efficiency. In this paper, we propose a novel approach called CryptFS, which is achieved by utilizing the file access mechanism and modifying the cluster chain structure to hide data. CryptFS can quickly hide data file with G bytes size in less than 0.1s. The time used for hiding and recovering data is irrelevant to the size of data file, and the reliability of the hidden file is high, which will not be overlaid by new created file and disk defragment.

We present a new high-payload joint reversible data-hiding scheme for encrypted images. Instead of embedding data in the encrypted image directly, the content owner first uses an interpolation technique to estimate whether the location can be used for embedding and generates a location map before encryption. Next, the data hider embeds the additional data through flipping the most significant bits （MSBs） of the encrypted image according to the location map. At the receiver side, before extracting the additional data and reconstructing the image, the receiver decrypts the image first. Experimental results demonstrate that the proposed method can achieve real reversibility, which means data extraction and image recovery are free of error. Moreover, our scheme can embed more payloads than most existing reversible data hiding schemes in encrypted images.

hiding data in acid （DNA） can facilitate annotation of important plant the deoxyribose nucleic the authentication and variety rights. A grant of plant variety rights for a new plant variety gives you the exclusive right to produce for sale and sell propagating material of the variety. Digital watermarking techniques have been proposed for a wide range of applications, including ownership protection, copy control, annotation, and authentication. However, existing data hiding methods for DNA change the functionalities of DNA sequences, which induce morphological changes in biological patterns. This paper proposes a high capacity data hiding scheme for DNA without changing the functionalities of DNA sequences. This scheme adaptively varies the embedding process according to the amount of hidden data. Experimental results show that the proposed scheme gives a significantly improved hiding performance than previous schemes. And the robustness and security issues are also analyzed.
