A Robust Data Hiding Scheme in Tree-structured Haar Transform Domain
نویسندگان
چکیده
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.

Attack-resilient Watermarking in the Haar Wavelet Domain
In this paper a watermarking method based on the Haar wavelet transform is proposed. The hiding procedure is performed in the LL subband of the first level of Haar decomposition of the image. The coefficients resilient to specific attacks are modified in order to obtain a robust embedding scheme. The proposed method is used to define a mask to perform the embedding in the wavelet transform doma...
متن کاملA commutative digital image watermarking and encryption method in the tree structured Haar transform domain
In this paper a commutative watermarking and ciphering scheme for digital images is presented. The commutative property of the proposed method allows to cipher a watermarked image without interfering with the embedded signal or to watermark an encrypted image still allowing a perfect deciphering. Both operations are performed on a parametric transform domain: the Tree Structured Haar transform....
متن کاملA Novel DWT Based Invisible Watermarking Technique for Digital Images
The two most aspects of any image based steganographic system are the quality of the stego-image & the capacity of the cover image. A lossless data hiding scheme is presented based on quantized coefficients of discrete wavelet transform (DWT) in the frequency domain to embed secret message. Using the quantized DWT based method, we embed secret data into the successive zero coefficients of the m...

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...
