Abstract This paper introduces a robust and secure data hiding scheme to transmit grayscale image in encryption-then-compression domain. First, host is transformed using lifting wavelet transform, Hessenberg decomposition redundant singular value decomposition. Then, we use appropriate scaling factor invisibly embed the of watermark into lower frequency sub-band image. We also suitable improve ...

Lattices have been conceived as a powerful tool for data hiding. While conventional studies and applications focus on achieving the optimal robustness versus distortion tradeoff, in some such hiding medical/physiological signals, primary concern is to achieve minimum amount of cover signal. In this paper, we revisit celebrated quantization index modulation (QIM) scheme propose minimum-distortio...
