Security analysis of robust data-hiding with geometrically structured codebooks
In digital media transfer, geometrical transformations desynchronize the communications between the encoder and the decoder. Therefore, an attempt to decode the message based on the direct output of the channel with random geometrical state fails. The main goal of this paper is to analyze the conditions of reliable communications based on structured codebooks in channels with geometrical transf...
متن کاملOn Security of Geometrically-robust Data-hiding
In this paper we analyze security of robust data-hiding in channels with geometrical transformations. We categorize possible decoding strategies for channels with geometrical transformations within the information-theoretic framework for geometrically-robust datahiding. Furthermore, considering template-based and redundantbased design of geometrically robust data-hiding systems, we provide the ...
متن کاملA Robust Data Hiding Scheme in Tree-structured Haar Transform Domain
A robust data hiding method is proposed. A generalized wavelet transform domain is used to design a private-key embedding scheme. Specifically, a binary mask is created in the Tree Structured Haar Transform (TSH) to select the most perceptually significant coefficients using leveladaptive thresholding. Experimental results show the effectiveness of the proposed approach.

متن کاملRobust Reversible Data Hiding for Multispectral Images
A robust reversible data hiding scheme for multispectral image is proposed in this paper. Different from the existing robust lossless data hiding schemes which use statistical quantity of the arithmetic difference of image blocks, this method shifts transform domain statistical quantity histogram to get a better performance for multispectral images. The statistical quantity of the average of th...
