Abstract

The square-root law of imperfect steganography ties the embedding change rate and the cover length with statistical detectability. In this paper, we extend the law to consider the effects of cover quantization. Assuming the individual cover elements are quantized i.i.d. samples drawn from an underlying continuous-valued “precover” distribution, the steganographic Fisher information scales as $\triangle^{s}$, where $\triangle$ is the quantization step and $s$ is determined jointly by the smoothness of the precover distribution and the properties of the embedding function. This extension is relevant for understanding the effects of the pixel color depth and the JPEG quality factor on the length of secure payload.

A steganographic method based upon JPEG and quantization table modification
Special issue: Intelligent multimedia computing and networking

In this paper, a novel steganographic method based on joint photographic expert-group (JPEG) is proposed. The proposed method modifies the quantization table first. Next, the secret message is hidden in the cover-image with its middle-frequency of the ...
A New LSB Matching Steganographic Method Based on Steganographic Information Table
ICINIS '09: Proceedings of the 2009 Second International Conference on Intelligent Networks and Intelligent Systems

Based on the researches of LSB (least significant bit, i.e. the last bit of a binary pixel value) matching steganographic method and the steganalytic method which aims at histograms of cover images, this paper proposes a new LSB matching steganographic ...
A Steganographic Method for Hiding Secret Data Using Side Match Vector Quantization

To increase the number of the embedded secrets and to improve the quality of the stego-image in the vector quantization (VQ)-based information hiding scheme, in this paper, we present a novel information-hiding scheme to embed secrets into the side match ...
